AFTER A delay of a fortnight, monsoon finally withdrew from the state and city on Sunday, as declared by the meteorological department. While the usual date for withdrawal is around October 1 for the state, the Met department declared the withdrawal of monsoon from the remaining parts of the state and Pune on Sunday.
According to Met department, there should be no rains for five continuous days and a significant decrease in humidity levels to declare withdrawal of monsoon.
While there have been intermittent rains across the state, a few dry spells due to the cyclonic systems have delayed the withdrawal of monsoon, said the officials.
The withdrawal largely depends on the weather and wind pattern. Normally, October 1 is when the monsoon starts withdrawing from western Rajasthan and continues through October, the officials added.
As per the Met forecast, the monsoon has further withdrawn from remaining parts of Bihar, Jharkhand, sub-Himalayan West Bengal, Sikkim, Odisha, Chhattisgarh, Maharashtra, Goa and Telangana.
“We should see further withdrawal of the monsoon from the northeastern parts and several parts of the Bay of Bengal, peninsular India and the Arabian sea in the coming two to three days,’’ stated a senior Met official.
From October 1, Pune has recorded 80.4 mm rainfall. There has been an excess of 25.4 mm rainfall with the delayed withdrawal, according to the data put up by the Met department.
While the country, as a whole, witnessed three per cent less rainfall than normal for the months of June to September. Till September, Pune had recorded excess rainfall of about 35 mm.
This is the first time since 2011 that the Met department was not able to correctly forecast the overall rainfall.
The department had first forecast ‘above normal’ rainfall, changing it to ‘normal’ later.
The delay in monsoon too, could not be established with the systems predicting rainfall in the first two weeks of October. This year may well be the third most delayed withdrawal after October 26, 2010.
The Met department had earlier stated that the withdrawal would take another week, but with the reduction of moisture and no systems they declared the withdrawal from the state beginning from Friday and finally completed withdrawal from the state on Sunday. The other years where there was a delay included October 19, 2013, while there have been two occasions where the monsoon has withdrawn from the state on October 12.
While the normal monsoon withdrawal from the country usually starts from October1, this year there was a fortnight’s delay which continued for all states across the country.
The Met experts have attributed the delay to the prevalence of moisture over northern parts of the country which saw rainfall. Rain-bearing systems too only saw good rains in October which delayed the withdrawal of monsoon.
