First half of October bring mostly excess rain over Peninsular India

The South-West monsoon, which has refused to take leave of the entire peninsula, has delivered mostly excess rainfall for the region during the first 15 days of October.

October 15-20 is the normal window for the reverse monsoon (North-East monsoon) to set in over the South Peninsula but there is no sign that would happen any time soon.

The remnant South-West monsoon continues to be active over a large part of the country except West India and North-West India from where it has withdrawn, though with a delay.

The prevailing low-pressure area in the Central Bay of Bengal is expected to intensify into a depression or a more advanced weather system and this would further delay the North-East monsoon.

But this should not worry the South Peninsula which benefits most from the North-East monsoon, since the entire region has already received good precipitation since October 1.

Kerala alone has a negligible deficit (two per cent) but all the rest Met subdivisions have received either 'excess' showers or 'large excess' showers during the period.

Those with 'excess' precipitation (In percentage figures) are: Tamil Nadu & Puducherry (+22); Coastal Karnataka (+38); Vidarbha and Chhattisgarh (+30 each); Odisha (+22); Jharkhand (+45); and Bengal (+29).

Those with 'large excess' are: South Interior Karnataka (+98); Rayalaseema (+184); North Interior Karnataka (+101); Telangana (+91); Marathawada and Madhya Maharashtra (+102 each); and Konkan & Goa (+65).

Apart from Kerala, Coastal Andhra Pradesh found itself in the 'normal category' but with a surplus of four per cent.

The rainfall figures for the region should improve further what with the expected rain from the prevailing 'low' and the depression likely developing from it.
