Kolkata: On Tuesday, pre-monsoon
showers have finally made an appearance over Kolkata bringing in massive relief
from scorching heat. In a span of 24 hours from 8:30 AM on Tuesday, the
city has recorded 4.6 mm of rain.
Light rains and thundershowers were
witnessed over many places and a few places have recorded good showers but for
short duration. Few places of the city have also witnessed hailstorm. In
wake of this, maximum temperature have also registered a good drop and are now
settling near normal. On Tuesday, mercury had come down to 36.3 degree Celsius
from 40.1degree Celsius in last 48 hours.
The weather activity is due to a
cyclonic circulation marked over Bihar and adjoining West Bengal. A trough is
also extending from this system up to Orissa cross Gangetic West Bengal.
Steady flow of humid southerly
winds from Bay of Bengal will continue to feed moisture over most parts
of Bengal including Kolkata. As a result, moderate to good rain and
thundershowers will continue for another 48 hours. Isolated chances of
thunderstorm and hailstorm are also expected.
These ongoing rains will be patchy in
nature, thus day temperatures will fall but weather will continue to be warm
and sultry. But evenings and nights will be far more pleasant.
Kolkata has not witnessed any rains
since April 8, leading to significant rise in maximum temperatures. On several
occasions, day temperatures were above normal average by 4-6 degrees amounting
to heat wave conditions.
Pre-monsoon rain and thundershowers
will continue over the city now onwards with a gap of 2-3 days.
