Another whip of squall, thundershower in city

The Regional Meteorological Centre (RMC), Kolkata, indicated heavy rainfall with squall on Monday and Tuesday evening due to the nor'wester.

"The latest Radar Observation indicates that thunderstorm is likely to affect certain parts of Purulia, Bankura and West Midnapur districts.

"It may be accompanied with lightening or hail or squall or moderate rain and strong winds reaching 50 to 60 km per hour or more," said a senior official at RMC, Kolkata.

Meteorologists spotted a cyclonic circulation on Bihar and the trough extended from there to north India. Another trough also extended from the same position to Odisha.

"Due to these weather features, light to moderate rains are likely over many parts of the northeast states, Sub-Himalayan West Bengal and East Bihar," Skymet weather, a private weather forecast agency informed.

"Trough generally brings uninterrupted rainfall. It is an elongated region of relatively low atmospheric pressure. In this case, there are two troughs — one had gone to Odisha and another towards Uttar Pradesh," another meteorologist explained.

The RMC predicted that the light rainfall may take place over Jharkhand, Gangetic West Bengal. "There is a strong possibility that rain will hit the city along with a few South Bengal districts on Monday and Tuesday. This rain accompanied by storm, will happen due to the cyclonic circulation formed on Bihar. This is actually known as nor'wester," the RMC official added.

Meteorologists indicated that there would be rainfall in Karnataka, Tamil Nadu and Kerala as trough was spotted over Andhra Pradesh and South Chhattisgarh. "Down south, a cyclonic circulation spotted over South Chhattisgarh and adjoining Andhra Pradesh. A trough extended from this region to North Interior Karnataka, western parts of Tamil Nadu and Kerala. South Karnataka, Kerala and interior Tamil Nadu will receive scattered afternoon shower till Tuesday. Bengaluru may also receive a spell or two of rain and thunderstorm," Skymet weather predicted.

Meteorologists confirmed that the after effect of cyclone "Marutha" had failed to bring rain in the city last week. It may be mentioned that the meteorologists had earlier predicted medium rainfall last week. But only negligible rainfall was recorded.

However, one person was killed and three others were injured as a nor'wester hit the city on Saturday evening disrupting rail and road traffic. Police said one person was killed and three others injured when a tree fell on a car near Airport Gate No. 1, on Jessore Road.

While the driver of the car was declared brought dead at hospital, the three other occupants were admitted there.
