KOLKATA: Even as the city was struck by a thunderstorm on Tuesday afternoon, the Met office predicted light to moderate rain on Mahalaya — to be observed on Wednesday.
Since monsoon currents are still active across the state, thunderstorms will continue. The rain on Tuesday was heavier in northern parts and fringes of the city even as south Kolkata received drizzles.
A low-pressure trough between Bihar and Odisha and a cyclonic circulation over Malda led to thunderstorms in the city and several districts of south Bengal, said the Regional Meteorological Centre (RMC). “Both systems are supplying moisture into the region. So long as these two remain active, thunderstorms and rain will continue,” said RMC director GK Das.
The weather could turn dry from the latter half of Thursday. “By then, the low-pressure trough and the circulation could move away. But sporadic rain can’t be ruled till monsoon recedes,” said Das. Kolkata has received almost double the normal volume of rain – 96% above the normal mark — in September even as Gangetic Bengal has recorded 31% excess rain.
