Map Information

Tropical storm ENAWO-17 has formed in the Southern Indian Ocean north-east of Madagascar. It is moving south-west and is currently foreseen to make landfall early 7 March on the north-eastern coast of Madagascar as a very intense cyclone, with extreme rainfalls and maximum storm surge height of one meter.

ENAWO-17 is predicted to have a high humanitarian impact based on the maximum sustained wind speed, the potentially affected population (up to one million people) and their vulnerability.

The present map shows the damage grade assessment in the area of Sambava (Madagascar). The thematic layer has been derived from post-event satellite image using a semi-automatic approach. The estimated geometric accuracy is 5 m CE90 or better, from native positional accuracy of the background satellite image.
