While the intense storms and rains of the past few days have subsided somewhat in South Bengal, dryness is not yet returning. Instead, cloud cover will persist and scattered light to moderate rainfall is possible in Kolkata and the southern districts. This will be coupled with oppressive humidity, which the Meteorological Department has warned could further increase discomfort in public life.
Influence of Monsoon Axis and Cyclonic Circulation
According to meteorologists, the monsoon axis currently extends from Digha towards the east and southeast, reaching the northeastern Bay of Bengal. Additionally, a cyclonic circulation is active over Bihar and Jharkhand. This axis, extending from Uttar Pradesh to Jharkhand, is supplying moisture to South Bengal. As a result, while the amount of rainfall in the south may decrease slightly, humidity will increase.
Weather Forecast for North Bengal
There are no signs of the rain stopping in North Bengal. Intermittent heavy rainfall has been occurring there since Sunday, and a warning of very heavy rainfall has been issued for Monday and Tuesday. In particular, there is a possibility of very heavy rainfall in the Darjeeling, Kalimpong, Alipurduar, and Jalpaiguri districts on August 11th and 12th. The rainfall will continue on Wednesday and Thursday, although the situation is expected to normalize somewhat from Friday.
Yellow Alert in Five Districts
A yellow alert has been issued for heavy rainfall on Sunday in the five northern districts—Darjeeling, Jalpaiguri, Kalimpong, Alipurduar, and Cooch Behar. The administration has already increased vigilance in hilly and riverbank areas, as excessive rainfall can increase the risk of landslides or flash floods.
Possibility of Thunderstorms with Rain in South Bengal
Today, Sunday, there is a possibility of thunderstorms with rain in at least seven districts of South Bengal. Of these, West Medinipur, Bankura, Purulia, West Burdwan, Birbhum, Nadia, and parts of Murshidabad are relatively more likely to experience rainfall. Rainfall will decrease further on Monday and Tuesday, but humidity-related discomfort will peak.
Indication of Rain Again in the Middle of the Week
On Wednesday and Thursday, there may be scattered rainfall again in various districts of South Bengal. Although heavy rainfall is forecast in some districts, it will be scattered. During this time, although there will be an abundance of clouds in the sky, the feeling of heat will increase further due to the combination of solar heat and water vapor.
Temperature and Humidity Situation in Kolkata
Although the possibility of rain is low in Kolkata, oppressive heat will increase due to the high amount of water vapor in the air. The city's minimum temperature on Sunday is 27.9 degrees Celsius, which is 1.1 degrees above normal. The maximum temperature on Saturday was 32.7 degrees Celsius, slightly above normal. Relative humidity is fluctuating between 66 and 93 percent.
Weather Outlook for the Next 24 Hours
In the next 24 hours, the temperature in Kolkata will remain between 27 and 33 degrees Celsius. Although rainfall will be low, the abundance of moisture in the air will make the heat unbearable. Meteorologists have advised residents of South Bengal to drink plenty of water and wear light clothing during this time.
Impact on Agriculture and Public Life
As the amount of rainfall decreases in South Bengal, agricultural work may pick up speed somewhat, but excessive humidity may increase crop diseases. On the other hand, the tea gardens and hilly areas of North Bengal are being more affected by the rain. Heavy rainfall can disrupt transportation and daily activities.
Call for Caution
The Meteorological Department has advised residents, especially those in North Bengal, to remain vigilant. They have been advised to avoid unnecessary travel in hilly areas, stay away from riverbanks, and follow the instructions of the administration. Although there is no possibility of any major disaster in South Bengal, people are advised not to stay in open spaces during lightning.
