Residents of the French territory of Mayotte braced Saturday for a storm expected to bring strong winds and heavy rain less than a month after the Indian Ocean archipelago was devastated by a deadly cyclone.
Mayotte was placed on a red weather alert from 1900 GMT on Saturday in anticipation of the passage of Cyclone Dikeledi to the south of the territory.
Authorities called for "extreme vigilance" following the devastation wrought by Cyclone Chido in mid-December.
Meteo-France predicted "significant rain and windy conditions," saying that very heavy rain could cause flooding.
Residents were advised to seek shelter and stock up on food and water.
The storm hit the northeastern coast of Madagascar on Saturday evening around 1630 GMT and was heading straight for the tourist island of Nosy Be.
It is expected to pass to the south of Mayotte on Sunday morning, according to forecasts.
"Nothing is being left to chance," Manuel Valls, France's new overseas territories minister, told AFP, referring to forecasts of "heavy and continuous rain" and winds of up to 110 kilometers per hour (kph).
As it hit Madagascar, average winds were estimated at 130 kilometers per hour, with gusts up to 180 kph.
The most devastating cyclone to hit France's poorest department in 90 years caused colossal damage, killing at least 39 people and injuring more than 5,600 in December.
"We need to be seriously prepared for the possibility of a close passage of the cyclone," the Mayotte prefecture said on social media platform X.
Prefect Francois-Xavier Bieuville, the top Paris-appointed official on the territory, said Mayotte would be placed on a red weather alert from 1900 GMT on Saturday.
"I have decided to bring forward this red alert to 10 p.m. to allow everyone to take shelter, to confine themselves, to take care of the people close to you, your children, your families," Bieuville said on television.
Messages in French and two regional languages were broadcast on radio and television to alert the population.
Bieuville told reporters Saturday that the cyclone was forecast to pass within 110 kilometers (70 miles) of the archipelago's southern coast.
"We even have systems telling us 75 kilometers. So, we have something that is going to hit Mayotte very closely", he said.
The storm intensified from a tropical storm to a tropical cyclone Saturday morning, but forecasters are not expecting it to further intensify.
More than 4,000 personnel have been mobilized in Mayotte, including members of police and the army, said the interior ministry.
The prefect has requested that mayors reopen accommodation centers such as schools and gymnasiums that sheltered around 15,000 people in December.
He also ordered firefighters and other forces to be deployed to "extremely fragile" shantytowns in Mamoudzou and elsewhere.
Potential mudslides were "a major risk", the prefect said.
"Chido was a dry cyclone, with very little rain," he added.
"This tropical storm is a wet event; we are going to have a lot of rain."
Mayotte's population stands officially at 320,000, but there are an estimated 100,000 to 200,000 more undocumented inhabitants living in shanty towns that were destroyed by the cyclone in December.
