Kolkata: Fairly widespread light to moderate rain and thundershowers with one or two heavy spells have occurred over West Bengal and a few places over Jharkhand.

A cyclonic circulation is seen persisting since last two days over East Bihar and adjoining Jharkhand and West Bengal. A deep trough is also seen running from Sub-Himalayan West Bengal to North Bay of Bengal up to 7.5 km.

In the last 24 hours from 8:30 am on Monday, Asansol recorded 25 mm of rain, Bankura 7 mm, Bardhaman 9.8 mm, Coochbehar 19.2 mm, Darjeeling 19 mm, Diamond Harbour 6.1 mm, Digha 52.9 mm, Jalpaiguri 12.7 mm, Kolkata 9.2 mm, Sriniketan 20.4 mm, Jamshedpur 18.2 mm, Ranchi 1.4 mm.

Now also conditions are favorable for good rains to continue over Gangetic West Bengal and Jharkhand for next two to three days. Therefore, temperatures over both these states are also expected to remain below normal.

Furthermore, during the month of April and May heavy to very heavy thundershower or thunder squall are very common over West Bengal and Jharkhand. They are usually accompanied by strong winds which sometimes reached to 80 to 90 kmph. Frequent lightning strikes are also very common which is one of the main cause of fatalities.

Most such thundershowers are triggered by clouds forming over the Chhotanagpur Plateau and drifting eastwards. An abundance of moisture caused by the combination of four weather systems, especially the cyclonic circulation over Bengal, led to rain-bearing clouds forming over south Bengal on Monday.

In view of the warnings issued by the weather office, the district administrations have alerted all the blocks, asking them to take precautionary measures so that such incidents can be averted. The villagers in various blocks have been asked not to work out on the field during a thundershower.
