Cloudy weather is expected to prevail in the city and South Bengal districts till the beginning of the next week.
According to the Alipore Meteorological Department, moisture would continue to flow into the coastal districts of Bengal, with cyclonic circulation in northern Bay of Bengal. It would result in cloudy weather, with scattered rainfall in some parts.
This would leave an effect on the temperature as well. The minimum temperature at night, however, would not drop to levels as low as it did just after Durga Puja. Due to sudden drop in temperature at night in the days after Durga Puja, city dwellers began expecting winter to arrive earlier this year.
However, it would take some more time, mainly due to cyclonic circulation in North Bay of Bengal, which is creating a barrier for the northerly wind to enter the state.
Usually, winter completely sets in the city by mid-December, with the minimum temperature falling to 16 degree Celsius in Kolkata. The process, however, begins by the end of October. But this time, cyclonic circulation is restricting the usual drop in temperature and allowing normal flow of the northerly wind.
The situation would become more complicated if on Tuesday a low pressure trough forms in south-eastern of Bay of Bengal, as predicted by the meteorological department.
The formation of the low pressure trough would result in sporadic rainfall in south Bengal districts by the end of this week. The maximum temperature recorded on Monday in Kolkata was 31.6 degree Celsius, which is one degree above normal and the minimum temperature was 24.7 degree Celsius, three degrees above normal.
