WESTERLY DIPS IN

The weather-setting low-pressure area over East-central and adjoining Northeast Arabian Sea has persisted from overnight on Sunday, an India Meteorological Department (IMD) said on Monday.

Widespread rainfall were reported from Tamil Nadu and Kerala during the 24-hours ending Monday morning, an IMD update said.

WESTERLY DIPS IN

The rains were scattered over Lakshadweep, Andaman and Nicobar Islands, Konkan and Goa, Madhya Maharashtra and Gujarat while being isolated over South Rajasthan, Marathawada and North Interior Karnataka.

Meanwhile, the ‘low' in the Northeast Arabian Sea system has come under the influence of an itinerant western disturbance crossing the Northwest border and dipping south into Northeast Arabian Sea.

The IMD expects westerlies associated with the eastward-bound system to drag the ‘low' north-northeastwards towards Gujarat coast, which is in line with international model outlooks.

On Monday, a trough originating from the ‘low' arched its way across as far north-northeast as into Southeast Rajasthan.

Towards the east, an upper air cyclonic circulation hung over Southwest Bay of Bengal and adjoining Coastal Tamil Nadu.

The US Navy's Fleet Numerical Meteorology and Oceanography Centre assessed that a remnant circulation and a likely offshore trough would linger even after the ‘low' has washed over South or Southwest Gujarat.

A weather warning issued by the IMD has spoken about the possibility of isolated heavy rainfall over South Tamil Nadu and Kerala on Tuesday and Wednesday also.

Interaction of excess moisture with the band of cool northwesterlies associated with the western disturbance and day-time warming of land may combine to trigger isolated hailstorms over Rajasthan, Haryana, Delhi, West Uttar Pradesh, West Madhya Pradesh and Gujarat during this period.

Meanwhile, the FNMOC expected the rains over West and adjoining Central India to linger until Sunday.

An intervening easterly wave is forecast to dump heavy rains over Sri Lanka and adjoining Southeast Tamil Nadu coast by Wednesday.

A remnant of the wave is shown erupting in isolated heavy falls over coastal North Tamil Nadu around Chennai around Friday and later over South Kerala.

An IMD outlook valid until Thursday said that fairly widespread rain or thundershowers would occur over Kerala, Lakshadweep, South Tamil Nadu and Andaman and Nicobar Islands.

Insat cloud imagery showed the presence of convective clouds over parts of North, West and South Peninsular India, South Bay of Bengal, South Andaman Sea and East Arabian Sea.

Fairly widespread rain or thundershowers would also occur over Gujarat, East Rajasthan, West Madhya Pradesh, while it will be scattered over West Rajasthan, Haryana, Delhi and Uttar Pradesh on Tuesday and Wednesday.

Scattered rain or thundershowers is expected to occur over Coastal and South Interior Karnataka, Konkan and Goa.

The western disturbance and moisture incursion from Arabian Sea is forecast to cause scattered rain or snow over the Western Himalayan region.

This would lead to a rise in minimum temperatures by 2 to 3 deg Celsius over parts of Northwest and Central India during this period.

Extended forecast until Saturday spoke about the possibility of fairly widespread rainfall over South Peninsular India.
