Cyclone Emnati crashed into the southeastern coast of Madagascar in the early hours of Wednesday, ripping roofs off houses and raising fears of flooding and food shortages in a region still recovering from the destruction inflicted by another tropical storm weeks ago.
There were no immediate reports of deaths or injuries from Emnati but local officials and witnesses reported extensive damage to houses and other buildings in at least one southeastern city.
More than 30,000 people were moved to safe accommodation before Emnati arrived.
Known for its wildlife and unspoiled natural treasures, Madagascar has now been hit by four major tropical storms in the last month, killing nearly 200 people already adding to issues of food insecurity.
A drought in the south of the country left around 400,000 at risk of starvation last year, according to the U.N. World Food Program.
The cyclones have again underlined how climate change may be affecting weather patterns and putting lives at risk in vulnerable places like Madagascar. The U.N. weather agency previously warned of more "high-impact tropical cyclones" that are linked to climate change hitting the region.
A string of aid agencies said that Emnati will be a double blow for the eastern and southeastern regions that were hit by Cyclone Batsirai early this month. Batsirai ultimately left more than 120 people dead and displaced 143,000.
Emnati made landfall around midnight local time in the district of Manakara Atsimo in the southeast, with average sustained winds of 135 kph (84 mph) and gusts as strong as 190 kph (118 mph), Madagascar's Department of Meteorology said. Six regions in the southeast are on red alert, most of them already hard-hit by Batsirai.
"We can't go out so it's hard to see what happened but from what I can see from the gendarmerie barracks, there's a lot of damage. Many houses no longer have roofs," said Lt. Col. "We have not received any calls because the telephone communication has been very disrupted. We have had no electricity and water since yesterday (Tuesday) morning."
Manakara resident Gabriel Filiastre said his family joined others in taking refuge inside the main hall of a hotel where he works as Emnati hit.
"My house is completely flooded," Filiastre said. "We couldn't sleep inside. It's a wooden house. I saw a lot of houses around our house that are destroyed. For us, this cyclone did more damage than the one before."
"Even in the hotel, there is a lot of damage. One of the walls collapsed ... the roof tiles have been blown away and some of the ceilings of the rooms have collapsed. We need help."
The U.N. World Food Program and other aid organizations have warned of the risk of critical food shortages due to crops being destroyed and transport links being disrupted.
Forecasters have also predicted eight to 12 more cyclones in the Madagascar region before the cyclone season normally ends in May.
