A severe Nor'wester lashed through Dhaka and northwestern region of Bangladesh late April 4, 2015 leaving at least 24 people dead and hundreds injured. Weather officials said this was the first severe storm in the usual spring storm season.
It left a tail of destruction uprooting hundreds of trees and flattening many tin and mud-built houses and snapping road and rail communication with affected areas.
Bogra district, 197 km from capital Dhaka, was worst hit with at least 19 casualties. Most of them died after they were buried under collapsed houses and trees while some were electrocuted by electrical wires from fallen poles, ZeeNews reports.
In Bangladesh and adjacent parts of India, an intense type of storm known as a "Nor'wester" occasionally brings high wind and very heavy rain, usually in spring. Based on event descriptions and the meteorological environments involved, it appears that at least some "nor'westers" are, in fact, progressive derechos.1
Bangladesh is affected by severe tornadoes and storms from March to mid-May ahead of the four-month-long wet monsoon season.
