Cyclone Sidr (2007)

Tropical cyclone Sidr was a category 5 cyclone which made landfall in Bangladesh on November 15 2007, causing a storm surge of up to 5m across much of the country. It was one of the worst natural disasters to occur in Bangladesh, with estimates of up to 10,000 deaths. 

Meteorological history

Sidr developed in the southern part of the Bay of Bengal, close to the Andaman islands. In developed and strengthened as it moved North-East. By the time of landfall at Bangladesh (89.8 E) on November 15th, the sustained winds were around 215 km/hr. After landfall, the storm dissipated rapidly.

The storm surge and its aftermath.

As is common in this area, the storm surge was the biggest killer from cyclone Sidr. Fortunately, at the time of impact the tide was low; had this not been the case the damage could have been even greater.

A storm surge of 5m was experienced in many places. The surge reached Galachipa, about 50km inland, and reached 3m depth at the city of Pirojpur about 80km inland. 

An assessment of the impact from satellite data can be downloaded from ReliefWeb.
