quote:New Zealand bracing for severe weather as Cyclone Hale approaches the country
Tropical Cyclone “Hale” formed on January 7, 2023, as the first named storm of the 2022/23 South Pacific cyclone season. The system tracked into New Zealand’s area of responsibility on January 8 and was reclassified as a tropical low by New Zealand’s MetService.
Even though Hale won’t be a tropical cyclone by the time it impacts New Zealand, it has the potential to cause heavy rain, powerful winds, and large waves
The worst weather is expected Tuesday, January 10. However, lingering impacts are still possible across the south and east parts of the North Island on Wednesday
There is still a lot of forecast uncertainty with this system, so it’s important to frequently check forecasts for your area
The system is currently located southeast of New Caledonia. It is forecast to move southeastwards before turning towards the North Island on Tuesday, January 10, and passing southwards over the central or eastern North Island on Wednesday. The system is expected to bring heavy rain, gale or severe gale winds, and hazardous coastal conditions to parts of the North Island and Marlborough from Monday through Thursday, January 20.1
According to MetService Meteorologist Peter Little, the most likely regions to be impacted by heavy rain are the Coromandel Peninsula, Gisborne, and Hawke’s Bay, while much of the North Island will experience gale or severe gale winds from the southeast and/or southwest.
Severe Weather Warnings and Watches have already been issued, with more areas to be added as the system moves closer and its track and intensity become clearer.
Eastern coastlines from Northland to Wairarapa are also expected to be hit by large waves on Tuesday and Wednesday.
Easterly swells of 4 to 6 m (13 – 20 feet) are forecast to affect these coastlines, potentially leading to coastal inundation and erosion around high tide.
The largest swells are expected to hit the Coromandel Peninsula, western Bay of Plenty, and Gisborne on Tuesday.
While the North Island prepares for the cyclone, the South Island is experiencing relatively settled weather due to a ridge of high pressure.
The West Coast, in particular, has been enjoying sunny and warm weather, with Hokitika recording its 4th highest maximum temperature of 28.2 C (82 F) on Sunday, January 8. This dry and warm weather is expected to continue throughout the week, with highs in the mid-twenties (C) and only a slight chance of showers.
quote:Cheneso makes landfall in Madagascar
Tropical Cyclone “Cheneso” formed around 12:00 UTC on January 18, 2023, as the fourth named storm of the 2022/23 South Indian Ocean cyclone season.
The system intensified further into a severe tropical storm, moving westward toward Madagascar.
At around 07:45 UTC (10:45 LT) on January 19, Cheneso made landfall north of the city of Antalaha in northern Madagascar with maximum sustained winds of 90 km/h (55 mph) and gusts up to 120 km/h (75 mph), according to Meteo Madagascar.
Even though Cheneso weakened after making landfall, wind gusts are still expected to cause harm or destruction when it comes to homes and infrastructure located in Sava and Analanjirofo districts.
Red alerts have been issued for those areas as well as Dana Region due to heavy rainfall (100 – 200 mm/ 4 – 8 inches in 24 hours) and high winds predicted from January 19-20.
Additionally, there is an elevated risk of flooding occurring in towns and regions that are prone to such events, particularly those in the northeast, highlands, and eastern coasts.
The heavy rains could extend over Boeny and the central lands and could persist until Sunday, January 22.
Maritime users between Cap d’Ambre and Mahanoro are therefore asked not to venture out to sea until the danger has completely passed.
quote:Cyclone Cheneso hits Madagascar and destroys roads to capital
Several districts of Mahajanga, in the northwest of Madagascar, have flooded as well as the roads that connect them to the capital, Antananarivo.
Cyclone Cheneso continues to hit the island with more than 15,000 people affected to date.
"I left my house because it was destroyed by the strong winds of the cyclone. The house tilted, so I ran away. My house was totally destroyed," said flood victim Bonne Fehy.
"All our things got wet, but we had put them up high. I am disabled, so some young people took me, and that's how I escaped. They carried me in a tricycle," said Perline Razanamalala, another flood victim.
In addition to the floods, the National Office of Risk and Disaster Management has recorded numerous landslides and landslides.
Olga Rasoanirina, director of the Boeny region, Ministry of Population and Social Affairs said "we have housed people since Sunday when there were big storms. We have housed people in this site, which is a public elementary school in the neighborhood, we have set up shelters for the victims and we have also distributed meals."
The latest official death toll is four, 14 missing and more than 8,000 affected.

Tropical Cyclone “Judy” formed on February 26, 2023, over the South Pacific Ocean and is now moving SW over the northern Vanuatu Islands. A Red Alert is in effect for Torba, Sanma, and Penama. This is the 4th named storm of the 2023 South Pacific cyclone season.
At 12:00 UTC on February 27 (23:00 LT), the center of Tropical Cyclone “Judy” was located about 200 km (120 miles) NNR of Vanua Lava and 320 km (200 miles) N of Maewo.
The maximum winds close to the center were estimated at 95 km/h (59 mph) and the system was moving W at 11 km/h (6.8 mph).
Damaging gale force winds of 63 – 87 km/h (39 – 54 mph) are expected to affect the provinces of Torba, Penama, Sanma and Malampa tonight and tomorrow.
Judy is forecast to move SSW while strengthening and passing very close to the Banks Islands (NE Vanuatu) on the morning of February 28 and to cross the central and southern islands (Epi, Efate, Erromango and Tanna) on February 28 and 29.
Heavy rainfalls are expected over the northern provinces of Vanuatu with flash flooding expected in low-lying areas, and areas close to the river banks, including coastal flooding later tonight (LT).
Seas will become rough to very rough with heavy swells expected over northern and parts of the central waters of Vanuatu.
A Red Alert is in effect for Torba, Sanma, and Penama, a Yellow Alert for Malampa province, and Blue for Shefa and Tafea provinces.
People throughout the affected regions are advised to continue to listen to Radio Vanuatu and all other Radio Outlets to get the latest warning on this system.
quote:Heavy rains produced by Cyclone Yaku cause severe flooding and landslides in western Ecuador
Heavy rain caused by Cyclone Yaku produced severe flooding and landslides in western Ecuador, resulting in the deaths of at least 3 people. The worst affected was Chone Canton in Manab Province. The National Meteorology and Hydrology Service of Peru (Senamhi) described Yaku as an unusual and unorganized tropical cyclone.
The Risk Management Secretariat of Ecuador (SGR) reported that three people lost their lives due to the extreme weather, with two fatalities caused by a landslide and one due to the overflow of the Mosquito River. Furthermore, approximately 2 000 people have been affected, and one house has been destroyed.
According to El Comercio, 90% of downtown Chone was flooded on March 7. In addition, damaged homes and crops were reported in nearby rural areas, forcing authorities to declare a state of emergency.
Two additional rivers, Garrapata and Chone, have broken their banks, causing further damage and danger to residents in the area.
National authorities have taken swift action to provide assistance and humanitarian aid to those affected. However, with the floods causing the evacuation of the Chone Basic Hospital, the situation remains challenging.
Despite the efforts made by the authorities, further rainfall is forecast for March 9. However, there is hope that the situation may improve by March 10, with drier conditions expected across the affected Manab Province.
The National Meteorology and Hydrology Service of Peru (Senamhi) has reported an unusual “unorganized tropical cyclone” off the north and central coast of Peru earlier this week.
This clockwise low pressure system is also responsible for the extreme rainfall in Tumbes, Piura, and Lambayeque, as well as the anticipated intensification of rains in La Libertad, Lima, and Ancash in the coming days.
Senamhi specialists identified the formation of this system at the end of February and have been closely monitoring its progress and potential impacts.
Cyclone Yaku, as it is known, is associated with the warming of the sea surface temperature and the second band of the Intertropical Convergence Zone (ITCZ).
quote:La Nina ended - El Nino on the way
After three consecutive years of an unusually stubborn pattern, La Nia has officially ended and El Nio is on the way, the National Oceanic and Atmospheric Administration said Thursday.
That could mean a less active Atlantic hurricane season, a more active season in the Pacific – and another spike in global temperatures, forecasters say.
El Nio is associated with a band of warm ocean water that forms in the central and eastern Pacific Ocean, which has consequences for weather patterns around the globe.
NOAA’s Climate Prediction Center said “neutral conditions” are in place now and are expected to last through early summer in the Northern Hemisphere for the first time since the initial La Nia advisory was issued in September 2020.
The prediction center also wrote its forecast now favors “El Nio forming during summer 2023 and persisting through the fall.”
The transition to El Nio during the later summer months could have major influence over the Atlantic and Pacific hurricane seasons.
“Tropical cyclone activity in the North Atlantic is more sensitive to El Nio influences than in any other ocean basin,” NOAA said.
Generally, El Nio reduces Atlantic hurricane activity, but has the opposite result in the Pacific, where warmer waters can produce more intense hurricanes.
The warmer the Pacific Ocean is, especially in the eastern region, tropical cyclone quantity and strength can tend to increase. The Atlantic, however, sees fewer hurricanes as a result of increased upper-level winds that prevent hurricanes from developing.
El Nio impacts California
El Nio also significantly impacts California’s weather and could mean a continuation of the current wet pattern already plaguing the state. Traditionally, El Nio brings increased rain and snow across the Golden State, especially in the cool season, leading to flooding, landslides, and coastal erosion.
“Southern California is generally much more impacted with El Nino conditions bringing higher than normal precipitation,” the National Weather Service in Sacramento, California said.
california snow green valley 022623
Snowfall tops 6.5 feet and rainfall tops 5 inches across southern California
But having a very robust La Nia winter could still have lingering effects this summer even as we transition into more of an El Nio pattern.
“Even though La Nia is coming to an end we are likely to see latent impacts for some time to come and therefore some of the … rainfall impacts of La Nia may still continue,” the World Meteorological Organization said.
“The lingering impacts of multi-year La Nia is basically due to its long duration, and continuous circulation anomaly, which are different from the single-peak La Nia event.”
That’s a cause for concern for many Californians, given the surplus of moisture across the state in the past two months.
Increased risk for global heat waves
The more widespread concern with the return to El Nio conditions for the first time since the summer of 2019 will be the warming ocean’s impact on global temperatures and heat waves.
“If we do now enter an El Nio phase, this is likely to fuel another spike in global temperatures,” said WMO Secretary-General Petteri Taalas.
In fact, 2022 was the warmest La Nia on record, and adding the additional heat of El Nio means the next year or two will likely climb even higher on the list of hottest years on record.

More than 300 all-time heat records were broken in the US this summer. See where it was the hottest.
“La Nia’s cooling effect put a temporary brake on rising global temperatures, even though the past eight-year period was the warmest on record,” said Taalas.
El Nio and La Nia are major drivers of Earth’s climate patterns, but not the only ones.
The North Atlantic Oscillation, the Arctic Oscillation and the Indian Ocean Dipole are also have influence and are taken into account for the WMO’s global seasonal climate updates.
The change in La Nia and El Nio patterns contributes to a widespread prediction of above-normal temperatures over land areas, according to those updates.
“The El Nio and La Nia phenomenon occurs naturally,” the WMO said. “But it is taking place against a background of human-induced climate change, which is increasing global temperatures, affecting seasonal rainfall patterns, and making our weather more extreme.”

quote:Major hurricanes expected to increase in 2023, researchers
Researchers at the University of Arizona, who have successfully forecast hurricane activity since 2014, the 2023 hurricane season is expected to be very active after two relatively quiet years.
The forecast calls for a total of nine hurricanes between June and November, five of them classified as “major” hurricanes. These major hurricanes have wind speeds of up to 150 miles per hour and fall under Category 3 or higher.
While the number of hurricanes making landfall is expected to be fewer than in previous years, the number of major hurricanes is likely to be similar to the 2017 hurricane season, which saw devastating hurricanes such as Maria, Harvey, and Irma. In general, the average number of major hurricanes per year is two.
Xubin Zeng, who leads hurricane season forecasting at the University of Arizona, attributes the expected increase in hurricane activity to higher ocean temperatures and rising sea levels, both caused by global warming.
Since water vapour is fuel for hurricanes, the increase in water vapour over the oceans due to global warming is expected to cause more major hurricanes, even if the total number of hurricanes does not necessarily increase. Additionally, higher ocean surface temperatures are creating the ideal conditions for hurricanes to form.
Rising sea levels are also affecting storm surges, which can cause flooding, and a 2020 study projected that by 2100, tidal surges and storm surges will cause 68 percent of coastal flooding.
Zeng stressed the importance of emergency management agencies in providing critical services to people in affected areas during the potentially active hurricane season.
People living on the coast and in hurricane-prone areas should be aware of the increasing threats to their homes and property due to climate change and prepare accordingly, Zeng added.
El Nio, La Nia, Hurricanes explained
El Nio and La Nia are two opposing weather patterns that occur in the equatorial Pacific Ocean, characterized by differences in sea surface temperatures, precipitation, surface pressure, and atmospheric circulation.
El Nio results in above-average sea surface temperatures in the eastern Pacific, while La Nia is characterized by a periodic cooling of sea surface temperatures. This year, the presence of El Nio is expected to decrease hurricane activity in the North Atlantic, but warm ocean surface temperatures over the Atlantic may increase it.
The UArizona Hurricane Forecast Team will update their predictions in June after determining which ocean basin will prevail. Hurricanes are severe storms that form over warm tropical oceans, beginning as areas of low pressure that intensify thunderstorm activity as they move through the moisture-rich tropics.
Warm ocean air rises, cools, and condenses into droplets that further fuel the storm by releasing heat. According to the National Oceanic and Atmospheric Administration, hurricanes are storms with winds of at least 74 mph.
While atmospheric winds are useful for predicting individual hurricanes, they are not useful for predicting hurricane seasons due to their short memory. By contrast, ocean temperature remains constant over a longer period, making it a better metric for predicting hurricane seasons ahead of time.

Hawaii's Maui County and Lahaina are being evacuated as terrible wildfires fuelled by deadly winds from Hurricane Dora are pummelling the US island state today in frightening scenes
Apocalyptic scenes as people drive through Lahaina in Hawaii, surrounded by flames on both sides
Terrified people are fleeing into the sea as brutal wildfires and Hurricane Dora tear through the island of Hawaii today, sparking apocalyptic scenes.
In what could be the worst natural disaster in Hawaii’s history since Hurricane Iniki in 1992, multiple evacuations are taking place across the islands in the popular tourist area of Maui County. In a situation described as "very chaotic" by the local government, several fires have destroyed homes and buildings across Maui and Lahaina and terrifying images and footage show whole areas engulfed in flames as families flee in cars with infernos either side.
Acting Governor Sylvia Luke has issued an emergency proclamation and activated the Hawaii National Guard. Local authorities say "multiple structures" have been burnt and power lines down as flames are fuelled by strong winds from Dora.
Trapped people are reportedly fleeing into the ocean. The US Coast Guard has rescued 12 people from the waters off Lahaina and has despatched boat and helicopter rescue crews to the islands, which are a US state.
The American Red Cross has despatched hero workers to launch emergency shelters and social media users are asking people to "please pray for Lahainā, Maui and all places currently affected by brush fires".
Explosions have been triggered as fire destroyed buildings on historic Front Street in downtown Lahaina, where people leaped into the ocean to escape, as shown by a video posted to social media by Alan Dickar:
Mr Dickar, a Front Street business owner, told local media: "Buildings on both sides were engulfed. There were no fire trucks at that point; I think the fire department was overwhelmed. That is the most important business street on Maui.”
Lahaina resident Tiare Lawrence spoke to local media and said the scenes were like the apocalypse as people ran for their lives from the flames.
She said: “It’s just so hard. I’m currently Upcountry and just knowing I can’t get a hold of any of my family members. I still don’t know where my little brother is. I don’t know where my stepdad is.
“Everyone I know in Lahaina, their homes have burned down.”
Maui County Government told local media they were "dealing with an immense amount of evacuations and structure fires in both Upcountry Maui and West Maui. We understand it is very chaotic out there or law enforcement personnel are all on scene and our emergency operating center is in full activation this evening with coordination between county, state and federal agencies."
Harrowing footage posted on Instagram shows people fleeing Lahaina surrounded by flames on either side, engulfed in the blazes and unable to see where they are going

quote:Severe Tropical Cyclone Jasper could become the earliest category four tropical cyclone in Australia's area of responsibility since 2005.
Cyclone Jasper formed over the Solomon Sea late on Tuesday before moving towards the south and gaining strength. By Wednesday night, Jasper had intensified into a category 3 severe tropical cyclone and the system is expected to reach category 4 strength on Thursday night.
If Jasper does reach category 4 strength as expected, it will be the earliest category 4 tropical cyclone in the Australian region for 18 years. The last cyclone that was stronger and earlier was Severe Tropical Cyclone Bertie, which reached category 4 in late-November 2005.
Jasper’s life as a category 4 tropical cyclone will probably only last a day or so before increasing wind shear (change of wind speed/direction with height) and an injection of dry air causes it to weaken from late Friday into the weekend, while moving towards the west.
This anticipated weakening is good news for communities living in eastern Qld because Jasper is expected to continue on a path towards the state’s east coast early next week.
While there is still a lot of uncertainty regarding Jasper’s strength and location beyond the weekend, there is growing model consensus that it will make landfall somewhere over the central or northern coast of eastern Qld. At this stage, landfall will most likely be between Cooktown and Mackay between Tuesday and Thursday, if the system does end up reaching the coast.
It’s still too early to be certain that Tropical Cyclone Jasper will make landfall and how strong it will be if it does. If you live in eastern Qld, be sure to stay up to date with the latest tropical cyclone advisories over the coming days.

quote:Tropical Cyclone “Jasper” makes landfall over the Far North Queensland coast, Australia
Category 2 Tropical Cyclone “Jasper” made landfall over the Far North Queensland coast, Australia at around 07:00 UTC on December 13, 2023, with sustained winds near the center of 100 km/h (62 mph) and gusts to 140 km/h (85 mph).
“Tropical Cyclone Jasper, category 2 cyclone is making landfall over the Far North Queensland coast,” the Australian Bureau of Meteorology said at 18:06 AEST (07:06 UTC) today.
“Damaging to destructive wind gusts are occurring on the Far North Queensland coast as Jasper slowly crosses the coast in the vicinity of Wajal Wajal, just north of Cape Tribulation. Jasper is expected to weaken as it moves inland tonight.”
There is a moderate chance that the cyclone could redevelop in the Gulf of Carpentaria during the weekend or closer to the eastern Top End coast early next week.
There is also a chance that it may even move closer to the northern or western Top End by mid-next week, where there is a moderate chance of it redeveloping into a tropical cyclone.
Locally intense rainfall which may lead to dangerous and life-threatening flash flooding is forecast to develop from tonight along the coast and adjacent ranges between Cooktown and Port Douglas as well as areas near the center of Jasper. Isolated six-hourly rainfall totals between 250 to 300 mm (9.8 – 11.8 inches) are likely with 24-hourly totals between 400 to 500 mm (15.7 – 19.7 inches) possible.
Heavy rainfall which may lead to flash flooding is also forecast to develop between Cape Flattery and Ingham. Six-hourly rainfall totals between 100 to 150 mm (4 – 6 inches) are likely, with isolated falls up to 250 mm (10 inches) along the coast and adjacent ranges. 24-hour rainfall totals between 150 to 250 mm (6 – 10 inches) are likely, with isolated falls up to 350 mm (14 inches) possible.
Destructive wind gusts of up to 140 km/h (87 mph) are expected near and to the south of the track between Wujal Wujal and Port Douglas.
Gales with damaging wind gusts of up to 120 km/h (75 mph) are occurring along the coast south of Cooktown, including Cairns.
Damaging wind gusts are expected to extend further along the coast and adjacent ranges between Cooktown and Innisfail in the evening. Damaging wind gusts to 90 km/h (55 mph) are possible further south to Cardwell and north to Cape Melville, and then extending inland to the Atherton Tablelands and as far as Palmerville and Chillagoe tonight, after the cyclone has crossed the coast.
Along the track of the cyclone, the damaging wind gusts may temporarily ease to lighter winds as the eye of the cyclone passes over.
A flood warning is current for the North Tropical Coast, parts of the Cape York Peninsula and Gulf Country.
A storm tide is expected along the north Queensland coast on the high tide during Thursday morning with total waters generally expected to approach or marginally exceed the Highest Astronomical Tide level. Large waves may produce minor flooding along the foreshore.
