A powerful nor’wester accompanied by heavy rain and thunderstorms wreaked havoc in Dhaka last evening, disrupting communication services and affecting the lives of city dwellers.
The wind velocity was 83km per hour (km/h), the highest measured so far this year.
A number of trees were uprooted in the storm in Bijoy Sarani and Agargaon and on Manik Mia Avenue, bringing vehicular movement to a grinding halt and causing inconvenience to commuters.

“Based on the velocity of winds, nor’westers can be classified into three categories such as low, moderate and severe. The velocity of a low-level nor’wester ranges from 61 to 90 km/h, moderate from 91 to 120km/h, and severe from 121 to 149km/h.”
The average wind speed of a tornado is 150km/h or more, he added.
