Storms and Floods

Tropical Storms

In the South Indian Ocean:

Tropical cyclone Hellen is located approximately 240 nm north-northwest of Antananarivo, Madagascar.

Extremely dangerous Category 4 Tropical Cyclone Hellen is bearing down on Madagascar after an extraordinary burst of rapid intensification brought the cyclone from a 60 mph tropical storm to a high-end Category 4 storm with 150 mph winds in just 24 hours. Hellen is forecast to strike Madagascar as a very intense tropical cyclone at about 12:00 GMT on 31 March.

The La RĂ©union weather service has issued a warning: Hellen is likely to be one of the most powerful tropical cyclones ever seen over the northern channel since the satellite era (1967). the likelihood is increasing for an extremely dangerous tropical cyclone landfall over the northwestern coastline of Madagascar between cape Saint-Andre and Mahajonga. the RSMC tropical cyclone storm surge RWP has been run and shows phenomenal sea elevations in the area exposed to the northerly winds.
