India Meteorological Department (IMD) has said in an extended weather outlook valid until Wednesday next that a fresh easterly wave would approach south peninsular India.

This goes to confirm global model predictions, which now indicate an incoming rain-head erupting over northern Sri Lanka and adjoining southeast Tamil Nadu coast later during the week.

PREVAILING SYSTEM

This is even as an existing weak easterly wave spends itself out over Sri Lanka with associated spilling over to coastal Tamil Nadu and parts of Kerala.

This would continue to affect extreme south peninsular India during the weekend, the IMD said.

Its weather update said that the 24 hours ending Friday morning saw rainfall being recorded at many places over Tamil Nadu, Rayalaseema and Kerala.

An Insat imagery revealed the presence of tall convective (rain-bearing) clouds over parts of coastal Tamil Nadu, southwest Bay of Bengal and southeast Arabian Sea.

RAIN, SNOW

Meanwhile, a prevailing western disturbance over north Pakistan and adjoining Jammu and Kashmir has dropped rain or snow at one or two places over sub-Himalayan West Bengal, Sikkim, Assam and Meghalaya during the last 24 hours.

Rain or snow would continue to occur at one or two places over Jammu and Kashmir on Saturday and Sunday also.

Fog to shallow fog has been forecast over parts of Uttar Pradesh, Bihar, Jharkhand and Gangetic West Bengal.

This may also extend into parts of Punjab, Haryana and Delhi in morning hours on Saturday.

RAINS FOR SOUTH

An outlook valid for the south peninsula said that rain or thundershowers would break out at many places over Tamil Nadu on Saturday and reduce in intensity thereafter.

This would likely be the lull ahead of the arrival of a stronger system as is being predicted from Tuesday onwards.

Rain or thundershowers have been forecast at one or two places over Kerala, Lakshadweep and Andaman and Nicobar Islands.

But rainfall may increase over Andaman and Nicobar Islands from Monday, signalling the arrival of the fresh easterly wave.
