Cyclone Batsirai weakened overnight but floods were still expected due to heavy rain after it hit eastern Madagascar with strong winds, the island's meteorological office said Sunday.
"Batsirai has weakened," Meteo Madagascar said, adding that the cyclone's average wind speed had almost halved to 80 kph, while the strongest gusts had scaled back to 110 kph from the 235 kph recorded when it made landfall on Saturday evening.
The cyclone, the second storm to hit the large Indian Ocean island nation in just a few weeks, was moving westwards at a rate of 19 kph, the meteorological services said.
But "localized or generalized floods are still feared following the heavy rains," it said, adding that Batsirai should emerge at sea in the Mozambique Channel later Sunday.
Batsirai made landfall in Mananjary district, more than 530 kilometers southeast of the capital Antananarivo, around 8 p.m. local time (1700 GMT) Saturday.
It reached the island as an "intense tropical cyclone", packing winds of 165 kph, Faly Aritiana Fabien of the country's disaster management agency told AFP.
The national meteorological office has said it fears "significant and widespread damage."
Just an hour and a half after it first hit land, nearly 27,000 people had been counted as displaced from their homes, Fabien said.
He said his office has accommodation sites, food and medical care ready for victims, as well as search and rescue plans already in place.
'Very serious threat'
The Meteo-France weather service had earlier predicted Batsirai would present "a very serious threat" to Madagascar, after passing Mauritius and drenching the French island of La Reunion with torrential rain for two days.
In the hours before the cyclone hit, residents hunkered down in the impoverished country, still recovering from the deadly Tropical Storm Ana late last month.
In the eastern coastal town of Vatomandry, more than 200 people were crammed in one room in a Chinese-owned concrete building.
Families slept on mats or mattresses.
Community leader Thierry Louison Leaby lamented the lack of clean water after the water utility company turned off supplies ahead of the cyclone.
"People are cooking with dirty water," he said, amid fears of a diarrhea outbreak.
Outside plastic dishes and buckets were placed in a line to catch rainwater dripping from the corrugated roofing sheets.
"The government must absolutely help us. We have not been given anything," he said.
Residents who chose to remain in their homes used sandbags and yellow jerrycans to buttress their roofs.
Cyclone still 'dangerous'
Other residents of Vatomandry were stockpiling supplies in preparation for the storm.
"We have been stocking up for a week, rice but also grains because with the electricity cuts we cannot keep meat or fish," said Odette Nirina, a 65-year-old hotelier in Vatomandry.
"I have also stocked up on coal. Here we are used to cyclones," she told AFP.
Winds of more than 50 kph pummeled Vatomandry on Saturday morning, accompanied by intermittent rain.
The disaster agency said the cyclone was expected to remain "dangerous" as it swept across the large island overnight and in the morning.
Flooding is expected due to excessive rainfall in the east, southeast and central regions of the country, it warned.
The United Nations was ramping up its preparedness with aid agencies, placing rescue aircraft on standby and stockpiling humanitarian supplies.
At least 131,000 people were affected by Ana across Madagascar in late January. Close to 60 people were killed, mostly in the capital Antananarivo.
That storm also hit Malawi, Mozambique and Zimbabwe, causing dozens of deaths.
The U.N.'s World Food Program pointed to estimates from national authorities that some 595,000 people could be directly affected by Batsirai, and 150,000 more might be displaced due to new landslides and flooding.
The storm poses a risk to at least 4.4 million people in one way or another, the International Federation of Red Cross and Red Crescent Societies said.
