Soms wordt een naam geschrapt als een eerdere orkaan met dezelfde naam veel slachtoffers heeft veroorzaakt of veel schade heeft aangericht.

Zo heeft Mexico gevraagd om de naam Odile van de namenlijst af te halen, omdat orkaan Odile in september veel overlast heeft veroorzaakt in het land. Tienduizenden toeristen werden geëvacueerd en Odile richtte flink wat schade aan. Odile is op de lijst Odalys geworden.

This is the same dust in the atmosphere that prevented significant tropical cyclone development for the last two years over the North Atlantic. All the haze shrouding The Bahamas this week may not be great for your health, but it has a major benefit: It helps stymie hurricanes and tropical storms. The haze actually is Saharan dust that drifted more than 4,000 miles from Africa, and abnormally heavy concentrations currently are blanketing the main region of the Atlantic where storms develop. The dust, denies the systems of their lifeblood - heat and moisture.

In The Bahamas, the dust is expected to remain thick, possibly for the rest of the week. It has lowered air quality from the good to moderate range. If you have extreme respiratory problems, stay inside air-conditioned facilities to minimize exposure. Anyone who works outside for any length of time also should be careful because of the combination of dust and high heat. Dust outbreaks occur when strong winds lift clouds of particles from the Sahara desert. Winds or tropical waves – areas of low pressure – then push the dust west across the Atlantic.

David vs. Goliath? 96L fights the El Niño factor
As of 2:00 pm EDT Monday, Invest 96L was located near 10°N and 31°W, moving west at about 10 mph. Located along a broad monsoon trough that coincides with the Intertropical Convergence Zone, 96L remains only loosely organized, with a large but unconsolidated area of showers and thunderstorms. Vertical wind shear is light (less than 10 knots), and 96L will encounter warmer sea-surface temperatures as it moves west-northwest (up to 28°C, or 82°F, by later this week), so the large-scale conditions favor gradual strengthening. The National Hurricane Center has been increasing the odds that 96L will develop: in its 8:00 am and 2:00 pm EDT updates, NHC gave the system a 50% chance of becoming a tropical depression in the next 48 hours and a 70% chance over the next 5 days. The RAMMB/CIRA Tropical Genesis Index is also maintaining high odds for development. Among the favored models for intensity, the 1200 GMT Monday runs of the statistics-based LGEM and SHIPS models, which rely heavily on climatology, bring 96L to Category 2 strength by Thursday. The dynamics-based HWRF and GFDL models, which simulate tropical systems within nested high-resolution grids, diverge on the future of 96L. The HWRF develops 96L into a Category 1 hurricane by Thursday, while the GFDL fails to develop 96L significantly. As we discussed in last week’s post on tropical cyclone modeling, HWRF features a dramatic increase in resolution this year, so it will be interesting to see if it correctly pegs the fate of 96L.

While it seems that 96L has a reasonable shot at becoming a tropical storm (which would be named Danny), it also faces some obstacles. Foremost is a huge area of dry air and Saharan dust that extends across the tropical Atlantic just north of 96L's path. As the system grows in size and strength, it would become more likely to ingest some of the dry, dusty air, which would hinder shower and thunderstorm activity. 96L may also encounter an increasing amount of vertical wind shear as it approaches the longitude of the Leeward and Windward Islands this weekend, assuming it survives up to that point. Over the northern Caribbean, shear has actually lessened from the near-record values observed earlier this summer, although shear values of 20 to 40 knots continue to prevail across the southern Caribbean. The ever-strengthening El Niño favors westerly wind at upper levels across this region, though it's possible that the relative lull in shear over the northern Caribbean will continue as 96L approaches. A weak upper-level low is forecast to become pinched off near the Bahamas, south of a building ridge over the northwest Atlantic; this low could become a growing influence on 96L's track and intensity as it moves west of longitude 60°W.

Eastern Atlantic / Africa

There are more systems in the pipeline, coming off of Africa.

NHC is already highlighting the western one and has upped the probability of becoming at least a tropical depression within the next five days.

If this observation from earlier this afternoon is correct, there's already a northwest wind around that side of the disturbance, meaning it has or is getting close to having a "closed" (fully circular) surface circulation already, and models predict that if it doesn't yet, it will soon.

And then latest model runs are consistent in showing it taking a track next week not too far from Danny's.

The one after that will come off the African coast this weekend, and looks to be healthy and have some chance to further develop too. Models are vacillating between a quickly out-to-sea track and one farther west.

Ignacio may threaten Hawaii early next week

Residents of Hawaii need to keep close tabs on Hurricane Ignacio, which was packing top sustained winds of 90 mph as of 5:00 pm HST (11:00 pm EDT) Thursday. Now located just under 1000 miles east-southeast of Hilo, Ignacio is on a fairly straightforward west-northwest course that should continue over the next several days. Simply extrapolating Ignacio’s track would bring the hurricane very close to Hawaii by Monday or Tuesday. Hurricanes on such a course typically weaken before they reach the islands, traveling over surface waters near the threshold for tropical development of around 26°C (79°F). In this case, Ignacio is getting a boost from favorable upper-level conditions as well as unusually warm sea-surface temperatures, roughly 2°C (3.8°F) above average for this time of year. NHC intensifies Ignacio to just short of Category 3 strength by this weekend, then gradually weakens it starting on Monday. The official forecast calls for Hurricane Ignacio to pass about 100 miles north of Hilo on Tuesday as a Category 1 storm with sustained winds of 80 - 90 mph. No hurricane has ever been officially recorded on the Big Island of Hawaii--the strongest event on record was Tropical Storm Iselle in 2014--so today’s forecast is noteworthy in itself. Beyond the five-day period, models are tending to bend Ignacio’s track slightly leftward, as upper-level ridging strengths to the north. The predicted steering currents and the very warm SSTs make Ignacio a force to be reckoned with, and all of the Hawaiian islands should take this hurricane seriously. Large swells will become a near-certainty over the next few days.

New tropical wave expected to emerge from Africa on Thursday

A tropical wave currently over west-central Africa is expected to move off the coast of Africa on Thursday, at a location a few hundred miles southeast of the Cape Verde islands. The Tuesday morning runs of the GFS model predicted some slow development of this wave late in the week as it moves west at 15 - 20 mph towards the Lesser Antilles Islands. Our other two reliable models for predicting tropical cyclone genesis, the European and UKMET models, depicted an atmosphere with higher wind shear, and little or no development of the new tropical wave. In their 8 am EDT Tuesday Tropical Weather Outlook, NHC gave the wave 2-day and 5-day odds of development of 0% and 20%, respectively.

New study reveals the possibility of hurricanes ‘unlike anything you’ve seen in history’

Last week, the nation focused its attention on the 10-year anniversary of Hurricane Katrina, the most destructive hurricane in U.S. history. As bad as the storm was, though, it wasn’t the worst storm that could have possibly hit New Orleans.

That’s true of many, many other places, too. And now, in a new study in Nature Climate Change, Princeton’s Ning Lin and MIT’s Kerry Emanuel demonstrate that when it comes to three global cities in particular — Tampa, Fla., Cairns, Australia, and Dubai, United Arab Emirates — there could come a storm that is much worse than anything in recent memory (or in any memory).

Granted, these theoretical storms are also highly unlikely to occur — in some cases, they are 1-in-10,000-year events, or even rarer. The researchers refer to these possible storms as “gray swans,” riffing on the concept of a “black swan” event, an unpredictable catastrophe, or highly impactful event. A “gray swan,” by contrast, can indeed be predicted, even if it is extremely rare.

The purpose of the study is “to raise awareness of what a very low probability, very high impact hurricane event might look like,” said Emanuel. The gray swan storms were generated by a computer model that “coupled” together, in the researchers’ parlance, a very high-resolution hurricane model with a global climate model. That allowed the researchers to populate the simulated world with oodles of different storms.

“When you do hundreds and hundreds of thousands of events, you’re going to see hurricanes that are unlike anything you’ve seen in history,” said Emanuel, a key theoretician behind the equations determining the “maximum potential intensity” of a hurricane in a given climate. Indeed, he has published in the past that a theoretical “hypercane” with winds approaching 500 miles per hour is possible in scenarios where an asteroid hits the Earth and radically heats up ocean waters, far beyond their normal temperature.

So what did the researchers see? Let’s take Tampa Bay, first. It hasn’t been hit by a major hurricane since 1921 — but that storm drove a 3- to 3.5-meter (10- to 11-foot) storm surge and caused dramatic damage. Earlier, in 1848, another storm produced a 4.6-meter surge (about 15 feet).

Why is Tampa Bay so vulnerable? Check out any good map that shows the water depth (the bathymetry) around the Florida peninsula. It’s deep off the east coast. But there’s an extraordinarily broad continental shelf off the west coast. And although the city of Tampa, proper, sits at the head of Tampa Bay, relatively far from the mouth and well removed from the barrier islands that get battered by the waves from the Gulf of Mexico, that’s a more vulnerable spot than you’d think.

“One can get much larger surges where the offshore waters are shallow, as is true along the west, but not the east coast of Florida. Also, surges can amplify by being funneled into bays,” Emanuel said Monday in an e-mail.

The new method allows the researchers to show that a worse storm than these historical examples is possible, especially with sea level rise and global warming. They simulated 2,100 possible Tampa Bay hurricanes in the current climate, and then 3,100 each for three time periods (2006 through 2036, 2037 through 2067, and 2068 through 2098) in an unchecked global warming scenario.

In the current climate, the study found that a 5.9-meter (19-foot) storm surge is possible, in a strong Category 3 hurricane following a similar track to Tampa’s classic 1921 and 1848 storms. Moreover, in a late 21st century climate with global warming run amok, the worst-case scenario generated by the model included a very different storm track, moving north along Florida’s Gulf Coast and then swerving inland at Tampa, that generated an 11.1-meter (nearly 37-foot) surge.

Granted, the study said that these two “gray swans” are exceedingly unlikely — less than 1 in 10,000 years for the 5.9-meter surge in the current climate. But it also said that global warming shifts the odds toward the worse surges.

“The more publicity of the hurricane risk in Tampa, the better,” Emanuel said.

The study also shows that for Cairns, Australia, a 5.7-meter (18-foot) storm surge is possible in the current climate, but that would happen less than once in 10,000 years. And perhaps most strikingly, it also suggests that an extremely powerful hurricane is theoretically possible where we’ve never yet seen them occur — the Persian Gulf.

The waters in the Persian Gulf are very hot and so contain considerable potential hurricane energy, but the atmosphere is normally too dry for hurricanes, Emanuel explained. Nonetheless, “physics says that you can have one,” he said. “‘It’s not likely, but it’s not impossible.”

Indeed, there have been several hurricanes or tropical storms that have entered the Arabian Sea, though none have made it into the Persian Gulf. But the study showed that in extraordinarily rare circumstances, it’s also possible for a hurricane to be generated there.

Indeed, it found that with 3,100 simulated events in today’s climate, it is theoretically possible to get a hurricane with winds of over 250 miles per hour — stronger than anything we’ve seen on Earth — and a storm surge of 7.4 meters (24 feet) affecting Dubai. Granted, it is hard to emphasize enough that this is a rare phenomenon — storms like this have “return periods of the order of 30,000–200,000 years,” the study said.

So, is all of this just a mathematical exercise — or something more? In the end, it’s kind of in the eye of the beholder, as it’s up to us to decide how much to worry, if at all, about an extraordinarily rare event. But you could make the case that a study like this helps us think a lot better about what risk is all about.

“You go out on the tail, the risk gets tinier and tinier and tinier, but the consequences of that event get exponentially larger,” Emanuel said.

Another healthy wave coming off Africa
African continues to generate an impressive supply of easterly waves that have at least a chance of developing into tropical cyclones as they move into the Atlantic. Our next tropical wave is in the process of moving from West Africa into the Atlantic at a fairly low latitude (see Figure 1 above). SSTs remain unusually high in this region, and I expect we will see this wave emerge into a tropical depression and perhaps become Tropical Storm Henri late this week. Once again, the tendency for high wind shear from the Caribbean northeastward will greatly reduce the odds that any tropical cyclone from the deep Atlantic tropics might approach North America relatively intact.

New African tropical wave worth watching
A tropical wave moving off the coast of Africa on Thursday has the potential to develop into a tropical depression early next week as it moves westwards across the Atlantic at about 15 mph. Though the wave does not yet have much spin or heavy thunderstorm activity, conditions are favorable for development, with wind shear a moderate 10 - 20 knots, ocean temperatures at 27.5 - 28.5°C (82 - 84°F), and only a modest amount of dry air from the Saharan Air Layer to the north of the disturbance. One of our three models for predicting tropical cyclone genesis, the UKMET model, forecasted in its 00Z Thursday run that the wave would develop into a tropical depression midway between the Lesser Antilles Islands and Africa by Sunday. Many of the 20 members of the GFS ensemble forecast also predicted development, though the operational high-resolution version of the GFS model did not. In their 8 am EDT Thursday Tropical Weather Outlook, NHC gave the wave 2-day and 5-day odds of development of 0% and 20%, respectively. This wave looks less likely to affect the Lesser Antilles Islands than the waves that spawned Grace, Erika, and Danny, but it is too early to be confident of this.

Tropical Storm Koppu is on track to threaten the Philippines this weekend. Those in Taiwan and Japan should also monitor the storm for potential impacts next week.
While Koppu is currently battling wind shear, the potential exists for it to go through a period of rapid intensification while crossing the Philippine Sea, resulting in a very powerful typhoon approaching the Philippines this weekend.

Luzon Island, especially northern areas, would then be at risk for flooding rain, damaging to destructive winds and dangerously rough seas this weekend. The extent and duration of these impacts will depend on how close Koppu tracks to the Philippines and its speed at that time.
"From Friday and into the weekend, Koppu is expected to slow significantly or stall, then turn to the north," stated AccuWeather Meteorologist Adam Douty.

"Due to the significant length of time Koppu is expected to remain near the island, flooding rain and mudslides will become a major threat," Douty continued. "If the center of the storm gets close enough to the island, several days of damaging wind are possible."
Based on current indications, Manila will escape the worst of the impacts.
Impacts from Koppu will not be limited to the Philippines. The turn to the north may cause Koppu to threaten Taiwan and Japan's southern Ryukyu Islands early next week with damaging winds and flooding rain.

Depending on the exact future track of Koppu, the rest of Japan and far eastern China may then face hazards later next week.
AccuWeather meteorologists will continue to provide updates on the expected track and more precise details of its potential impacts to lives and property in the upcoming days.
Behind Koppu is Tropical Depression 25W, which expected to strengthen into the next tropical storm in the western Pacific Basin at midweek.
Douty expects this system to cross the Northern Mariana Islands on Friday and will either be at or approaching typhoon status.
"Saipan is probably the largest island that will be impacted by this system as it will pass to the north of Guam," stated Douty.
Latest indications point toward this system then curving to the north, then northeast away from Japan next week.

Lijkt niet enorm veel voor te stellen alsnog.

En Patricia is een categorie 5 geworden. Merk er hier in Guadalajara nog weinig van behalve dat het de hele dag bewolkt is geweest en zo nu en dan wat motregen. Ben benieuwd naar morgen wanneer het meer richting deze kant trekt.

Patricia groeit uit tot een apocalyptisch monster: windsnelheden nu naar 325 km/uur en barometer op 880 hPa.

Technically, Patricia is the strongest tropical cyclone in terms of wind speed since reliable record began. Typhoons listed by WeatherGuesser did have higher wind speed (for example, Nancy is a 185-kt storm), but JTWC has stated that the estimates back in the 1960s might not be reliable. For Haiyan, JTWC had it at 170 kt, but it should be noted that no aircraft were flown into the storm, and it is based solely on satellite imagery (i.e. the Dvorak technique). For Megi, despite recon supporting 170 kt, JTWC had it at 160 kt in their best track. Storms like Haiyan may have higher intensity, but there were no solid proof. So in the official record, Patricia is no. 1.

Sommige geleerden zoeken ook verbanden tussen orkanen en aardbevingen.
Ik ga d'r eens op letten of centraal Mexico in de komende week wordt getroffen door een 6.0 of hoger.
