Sometimes they even continue until late in the evening. Direct exposure to these winds may even prove to be fatal. (iii) Dust storms are very common during the month of May in northern India. These storms bring temporary relief as they lower the temperature and may bring light rain and cool breeze. (iv) This is also the season for localised thunderstorms, associated with violent winds, torrential downpours, often accompanied by hail. In West Bengal, these storms are known as the ‘Kaal Baisakhi’ calamity for the month of Baisakh.
