The cyclone made landfall in Bangladesh in the evening of November 15, SIDR and its surge resulted in thousands of deaths and massive destruction of coastal communities.

Moderate upper-level wind shear inhibited its organized development, however strong diffluence aloft aided in developing convection.

A better defined cyclonic circulation developed when the vertical shear begun decreasing. Based on that development, a “Tropical Cyclone Formation Alert” was issued for the region.

Still later on November 11, the system intensified as it moved slowly in a north-westward direction. Later that day, it appeared that the cyclone’s brunt of force would be felt by the less populated areas known as “Sundarbans”, the mangrove forest that stretches along the western third of Bangladesh’s coast – a world heritage site that is home to the rare Royal Bengal Tigers.

However, this did not happen.

A catastrophic surge flooded the area and caused most of the deaths and the damage. Bangladesh is a country that is almost entirely situated on an an enormous delta that has been formed by the confluence of Ganges, Brahmaputra, and Meghna rivers and their tributaries. This extensive river system is constantly fed by waters of melting snow from the Himalayan mountains. Thus, the entire country is mostrly flat and extremely vulnerable to flooding.

Cyclone “SIDR” generated maximum flooding. The cities of Patuakhali, Barguna and Jhalokati District were hit hard by the storm surge that was over 5 meters 16 ft In height. Fortunately, the cyclone made landfall when the tide was low, so the surge was not as high as it could have been. Also, cyclone surge flooding occurred earlier along the coastal areas of north Chennai in the southern state of Tamil Nadu in India.

The storm’s surge flooded areas up to a height of 3 metres 9. Death Toll and Damages. Most of the cyclones that have made landfall in Bangladesh in the past have caused thousands of deaths. According to official accounts 3, people lost their lives. However this is believed to be inaccurate.



The actual death toll may never be known with certainty. It is estimated that perhaps up to 10, people actually lost their lives, with thousands more injured, or missing. Thousands more were displaced and became homeless. The damage in Bangladesh was extensive. About a quarter of the World Heritage Site “Sunderbans” was damaged. The entire cities of Patuakhali, Barguna and the Jhalokati District were hit hard by the cyclone’s surge of over 5 meters 16 ft.

There was extensive flood damage at Barisal and at Baniashanta, across from the port city, Mongla, as the cyclone’s surge rolled in. In the town of Mothbaria, one of the towns in the very center of the devastation, there was hardly anything left standing, except of a few brick and concrete buildings. Houses and and schools were demolished.

The storm’s surge washed away all roads in the region. About fishing boats were unnaccountable and over 3, fishermen were reported missing. Much of the capital city of Dhaka was also severely affected due to the winds and the flooding which affected the city’s infrastucture. Electricity and water service were cut. The agricultural industry of Bangladesh was devastated by the flooding which covered about1 million hectares of farmable land.

Bangladesh Cyclone (Sidr), 2007

In brief, “SIDR” affected about 2 million families banglsdesh about 9 million people. The warning was disseminated by emergency response authorities in Bangladesh, prompting massive evacuations of the low-lying coastal areas.

A total of 2 million people were evacuated to emergency shelters cyclons that probably contributed to the lower death toll. However, in spite of the warning, thousands of people were stranded on tiny little islands dotting the coastline, with no place to go because of the flatness of the land and its low elevation above sea level. There was simply no higher ground or shelters on stilts to evacuate to. Overall, the early warning system, cyclonee and massive evacuations, resulted in a much lower death toll than that caused by the cyclone.

However, property damage was as severe or even worse that that caused in Past Cyclones and Cyclone Surges in Bangladesh.

Bangladesh is extremely vulnerable to seasonal cyclones and floods. This is because a very large part of Bangladesh is located on river deltas with low elevation above the sea. These areas routinely suffer large-scale losses of life and property. Cyclones and depressions threaten the country every year during pre-monsoon and post monsoon seasons. In the past, cyclones and their surges originating in the Bay of Bengal, killed hundreds of thousands of people.


In a cyclone with winds up to kmh made land fall in Bangladesh and killed about 10, people. Another cyclone inwith winds of up to kph killed 12, people. The cyclone that made landfall in the coastal Chittagong region, killed more than 11, people and destroyed about 1 million homes. The deadliest of all was the cyclone of Nov 12, It made landfall on Bangladesh with winds of up to kmph and a surge that was 10 meters high.
