Localised disturbances are forecast to sustain the churn in south peninsular India until March 1 while their better known counterparts across the northwest border could keep the pot boiling in the north till as far as March 9, say latest available outlook by global weather models.

In the south, the confluence of northeasterlies-to-easterlies from the Bay of Bengal and southerlies from equatorial Indian Ocean has created some unstable weather and resultant thundershowers around the peninsular south.

EASTERLY CAULDRON

In east and east-central India, a western disturbance that just exited the region has set off its tail wagging as indicated by formation of trough, confluence of opposing wind streams and convection.

This is at a time when a fresh ‘active' western disturbance has set up a perch over north Pakistan and its steamy front-end has set up clouds and snow over Jammu and Kashmir and the rest of the hills.

A number of models have picked the Comorin seas between equatorial Indian Ocean and southeast Arabian Sea to be the hot spot that would drive weather into the adjoining landmass of south Tamil Nadu, Kerala and parts of Karnataka during the rest of the week.

WIDESPREAD RAIN

Some of them also saw persistent westerly flows scooping up a circulation from east-central Arabian Sea into the Mumbai coast and onward into Madhya Pradesh.

An India Meteorological Department update said on Tuesday evening that fairly widespread rain or thundershowers occurred over coastal Andhra Pradesh and Tamil Nadu during the previous 24 hours.

It was scattered over Kerala, south interior Karnataka, Orissa and Gangetic West Bengal while being isolated over Sikkim, Manipur and Jharkhand.

Clear skies on Monday night brought minimum temperatures to below normal by 2-3 deg Celsius over parts of central India. Lowest minimum temperature of 5.2 deg Celsius was recorded at Adampur in Punjab in the plains of the country.
