Circulation loses steam but showers to hit Kolkata on Tuesday – Times of India

Kolkata News

Kolkata: Even as cyclone Gulab headed towards north Andhra Pradesh and Odisha coasts between Kalingapatnam and Gopalpur, threatening to hit land around midnight on Sunday, Kolkata and south Bengal remained unaffected by it.
The city, however, is set to receive moderate to heavy rain between Tuesday and Wednesday. Weathermen have sounded a rain alert for Kolkata triggered by a cyclonic circulation that will emerge over northeast and east central Bay of Bengal on Monday and had been predicted to intensify into a low pressure over the subsequent 24 hours, but has now turned weaker. “The system, however, has got diluted and may not intensify into a low-pressure now. It will head northwestwards and could reach the Bengal coast on Wednesday, and cause moderate to heavy showers across Kolkata and Gangetic Bengal,” said Regional Meteorological Centre (RMC) director GK Das.
He added that depending on the pace of movement, the system could start having an affect on south Bengal and Kolkata on Tuesday. “We expect moderate to heavy rain either on Tuesday or Wednesday, including an intense spell. Subsequently, the circulation will lose sting and pass away but light to moderate monsoon raiin will continue,” said Das.
The city received spells of light rain on Sunday but it was unrelated to the approaching cyclone, said the Met office. “Local thunderstorms have been striking Kolkata and its neighbouring districts over the last few days and Sunday was no exception,” said an official.
Gulab was likely to have a landfall with a wind speed of 75-85 km/hr, gusting up to 95 km/hr. The Met office sounded a rain alert for East Midnapore and South 24 Parganas under its impact on Monday.
On Tuesday, however, heavy rain has been forecast in Kolkata and south Bengal districts even as the cyclonic circulation hits coast and approaches the city.
Squally winds reaching a speed of 30-40 km/hr have been predicted along the Bengal coast including East Midnapore, South 24 Parganas, Jhargram, Howrah, Hoogly and Kolkata.
Even if the circulation loses sting, Kolkata may still receive 70 mm – 110 mm rain between Tuesday and Wednesday.
