Description of the event

On Monday, the tropical island of Madagascar was hit by Cyclone Giovanna. Since the storm, two people have been killed and in total five deaths have been reported.

Offices, schools and businesses have been closed due to power cuts in several areas. Telephone lines have also been cut after the cyclone.

The entireity of the damage to the island is not yet known, however, officials warn to expect further danger affecting property and loss of human life. So far, Vatomandry district, where the storm first began, has been badly damaged and mudslides have been reported in the Toamasina-Antananarivo area.   

Government officials issued initial warnings to residents of the Cyclone on Monday. However, the intensity or impact of the storm had not been explained very well. The severity of the Cyclone has left many residents in shock.

Further rainfall between 10 – 20 inches is expected to cover the entire Island and there are fears that this could lead to dangerous landslides.

A rescue operation is underway in the Vatomandry district; helicopter flights will assess the extent of damage caused. Food and shelter will be provided where it is needed most.
