A tropical cyclone designated 03S, named Ava at 09:00 UTC, January 3, has formed east of Madagascar and is currently affecting Reunion, Mauritius and especially northern Madagascar where heavy rain is already causing problems. This system is expected to continue organizing and gaining strength until it makes landfall early Friday, January 5, 2018 (UTC) along the northeastern coast of Madagascar. Be ready for strong winds, dangerous storm surge, heavy rain, flooding and landslides.
Ava is the first named cyclone of the 2017-18 South-West Indian Ocean cyclone season. It comes unusually late in a season which runs November 15 through April 30/May 15.
Showers produced by TC03S, now Ava, started across northern Madagascar late Tuesday, January 2 and intensified overnight Wednesday, reaching close to and over 200 mm (7.8 inches) in some places by Wednesday morning. Reunion and Mauritius saw first drops of rain around 09:00 UTC Tuesday and accumulated close to 100 mm (3.9 inches) in places over the next 24 hours.
This is a slow-moving cyclone with a potential to drop huge amounts of rain on Madagascar over the next couple of days, before and after landfall which is expected sometime around 09:00 UTC on January 5 in the vicinity of Toamasina (Madagascar is UTC+3).
These pre-landfall rains could set the stage for some serious flooding after already heavily soaked ground receives more intense downpours.
Tropical storm-force winds are expected as well as dangerous storm surge on top of rainfall amounts of 200 - 400 mm (8 - 16 inches), locally over 600 mm (24 inches).
Reunion and Mauritius are not in a direct track of this storm but will experience its effects over the next couple of days.

Tropical Cyclone "Ava" made landfall in Toamasina, Madagascar on January 5, 2018 with maximum sustained winds of 167 km/h (103 mph), an equivalent a Category 2 hurricane on Saffir-Simpson Hurricane Wind Scale. Ava is dropping heavy rain on Madagascar for several days now and is expected to continue producing heavy rains, strong winds and flooding as it moves over and along the coast of Madagascar over the next couple of days.
Ava is the first named cyclone of the unusually slow 2017-18 South-West Indian Ocean cyclone season. The season officially began on November 15, 2017, and will end officially on April 30, 2018, with the exception for Mauritius and Seychelles, for which it will end on May 15, 2018.
It reached hurricane strength with maximum sustained winds of 167 km/h (103 mph) around 15:00 UTC on January 5, a couple of hours before it made landfall.
Rising water levels have been observed in the Alaotra Mangoro and Analanjirofo regions, while flooding, interruptions to communications networks and power cuts have been reported in Fokontany Ambinany (Soanierana Ivongo), according to UN OCHA. Preventive evacuations began in Brickaville on January 4.
Météo Madagascar, the national weather service for the country has issued red alerts and yellow alerts that cover a large area of the island's east coast.
Ava's interaction with land has somewhat weakened it and further weakening is expected as it traverses the country, but its heavy rain and strong winds will remain a significant threat to lives and property over the weekend.
There is a very high risk of major flooding and landslides as some places might receive as between 200 and 400 mm (8 - 16 inches) of rain and as much as 600 mm (24 inches) total.

Antananarivo - Twenty-nine people died and more than 80 000 were affected after tropical cyclone Ava tore through Madagascar last week, authorities said on Monday.
Seventeen people died on Monday, after a house crumbled following a mudslide in the Ivory suburb, south-east of the capital Antananarivo.
"On a national scale, the provisional toll is 29 dead, 22 missing, 17 170 displaced and 83 023 affected," the National Bureau for Risk and Catastrophe Management said in a statement.
The cyclone, which made landfall on Friday morning, lashed the eastern part of the African island off Mozambique with violent winds and heavy rains before moving off the territory on Saturday night.
The cyclone caused flash flooding in the capital Antananarivo and the port city of Toamasina and in the eastern town of Tamatave. Several homes were without power and roads cut off by felled trees.
Madagascar, one of the world's poorest countries, is regularly hit by cyclones.
In March last year, cyclone Enawo killed at least 78 people.

Tropical Cyclone "Joyce" formed late January 10, 2018 (UTC), near the west Kimberly coast, Western Australia. The system is expected to intensify while moving in a S to SW direction. There is a risk of a severe tropical cyclone impacting the Pilbara or far west Kimberley coast during Friday or early on Saturday, BOM warns. This is the 5th named storm of the 2017-18 Australian region tropical cyclone season.
As of 06:47 UTC (14:47 AWST) on January 11, the center of Tropical Cyclone "Joyce" was located about 90 km (56 miles) NW of Broome and 155 km (96 miles) N of Bidyadanga. The system has maximum sustained winds of 75 km/h (46 mph) with wind gusts to 100 km/h (62 mph) and is moving S at 9 km/h (5.6 mph), according to BOM.
Cape Leveque to Port Hedland, including Broome and Port Hedland, as well as remaining inland parts of the far western Kimberley and far northeast Pilbara are currently in the warning zone.
Port Hedland to Dampier, including Karratha and Dampier, as well as remaining inland parts of the central and eastern Pilbara, including Nullagine, Marble Bar, Telfer, Newman and Tom Price are in the watch zone.
According to BOM, gales with gusts to 100 km/h (62 mph) are possible today between Cape Leveque and Bidyadanga. Gales may extend to areas between Bidyadanga and Wallal Downs during Thursday evening (local time), and to areas between Wallal Downs and Port Hedland on Friday. If the system tracks further to the west, gales will be possible in areas between Port Hedland and Karratha on Saturday.
Destructive winds with gusts to 130 km/h (81 mph) may develop in coastal parts between Beagle Bay and Wallal Downs, including Broome, on Thursday evening if the system is close enough to the coast. Destructive winds may extend to Pardoo Roadhouse during Friday.
Very destructive winds with gusts to 180 km/h (112 mph) are possible near the center of the system on Friday, if it develops into a severe tropical cyclone.
Tides will be higher than expected between Cape Leveque and Pardoo Roadhouse, BOM warns.
Heavy rainfall is expected over the northwest and west Kimberley coast, extending to the far eastern Pilbara during Thursday. Widespread daily rainfall totals of around 50 to 150 mm (1.9 - 5.9 inches) are expected with isolated heavier falls of 150 - 300 mm (5.9 - 11.8 inches) possible.
