Tuesday, July 27: Parts of east India are set to experience some enhanced rainfall activity this week starting today, i.e. Tuesday, July 27.

According to the India Meteorological Department (IMD), a cyclonic circulation and a related low-pressure are located near north Bay of Bengal as of Tuesday morning.

From here on, The Weather Channel’s met team has indicated that the low-pressure system may gradually move westwards in the days to come, reaching West Bengal on Thursday, and Jharkhand and adjoining areas by Saturday.

This system is expected to influence the weather across the East Indian states, as per the IMD. It will cause enhanced rainfall activity in the form of fairly widespread to widespread rains, with isolated heavy to very heavy falls, over the region starting Tuesday, July 27.

Heavy rainfall alerts in place

The Weather Channel’s met team has predicted isolated heavy to very heavy showers across West Bengal, Odisha and Jharkhand from Wednesday to Friday, and over Bihar on Thursday.

In view of this forecast, the IMD has issued a red warning over Gangetic West Bengal on Wednesday and Thursday, and over Jharkhand just for Thursday. The advisory urges residents to ‘take action’ in order to keep themselves safe from the rough weather.

Within West Bengal, the IMD’s regional met centre in Kolkata has indicated a strong likelihood of heavy to very heavy falls over the districts of Nadia, North & South 24 Parganas, East & West Midnapore, Howrah, Hooghly and East Burdwan on Wednesday, while heavy showers may occur over Murshidabad, Jhargram, Purulia, Birbhum, Bankura and West Burdwan.

On Thursday, the districts of Birbhum, East & West Burdwan, Howrah, Hooghly and North 24 Parganas could witness heavy to very heavy rains, while South 24 Parganas, Nadia, Murshidabad, East & West Midnapore, Jhargram, Purulia and Bankura may be in for heavy rainfall.

The district of Kolkata, which houses the state capital, is also expected to receive heavy rains during this 48-hour period.

Further, the IMD has issued orange alerts over the states of Bihar and Odisha in this period, so as to urge their residents to ‘be prepared’ for unstable conditions as well.

Varied monsoon activity over East India thus far

Since the beginning of the monsoon period on June 1, the eastern Indian states have had varied experiences as far as the amount of rainfall received is concerned.

Between June 1 and July 26, the state of Bihar has recorded 550.2 mm rain—a whopping 20% higher than what it typically receives in this period. Meanwhile, West Bengal (645.9 mm) and Jharkhand (443.9 mm) have both recorded ‘normal’ precipitation in this time frame; whereas Odisha, at 399.6 mm, has suffered a 20% ‘deficit’ as compared to its long-term average.
