With the Monsoon unlikely to make an entry in West Bengal soon, the Met department Monday said that day temperatures in South Bengal are likely to be above normal by two to three degrees Celsius.
It said that heat wave condition is "very likely" to prevail over Purulia, Bankura, West Burdwan, Birbhum, West Midnapore and Jhargram districts of West Bengal during the next three days.
The weatherman said that maximum temperature is likely to be above normal by two to three degrees Celsius in Kolkata, North 24 Parganas, South 24 Parganas, East Midnapore, Howrah, Hooghly, Nadia, Murshidabad and East Burdwan for the next three days.
Advent of the Monsoon in South Bengal, which occurs normally on June 9, is likely to be delayed by at least a week. Monsoon hit the Kerala coast on Saturday after a delay of a week.
The Met department said that heavy rain is likely to occur in sub-Himalayan West Bengal districts of Darjeeling, Jalpaiguri, Coochbehar, Alipurduar and Kalimpong districts. Lack of pre-monsoon showers have led to higher day and night temperature in south Bengal.
In Kolkata, the highest day temperature on Monday was recorded at 36.6 degree Celsius, two notches above normal.
