The Hindu Business Line : Heat in North above normal

Thiruvananthapuram, March 3 Northwest and central India are sizzling under above normal temperatures and India Meteorological Department does not find any respite from the prevailing conditions at least for the next two days.

Maximum temperatures continued to remain above normal by 6-8°C over the western Himalayan Region, Haryana, Delhi and North Rajasthan. They were slightly less (4-6°C above normal) over the remaining plains of northwest India, Madhya Pradesh and Vidarbha.

LESS AMPLITUDE

A western disturbance ambling in from the northwest border may not possess the amplitude to cover the wheat growing belt in the northwest. The incoming system has parked itself over Jammu and Kashmir and adjoining north Pakistan and will start affecting the western Himalayan region two days from now.

The system has thrown up an induced cyclonic circulation, which on Monday lay over central Pakistan and adjoining northwest Rajasthan and Punjab. It is forecast to move in an east-northeast direction and largely skip the Rabi farmlands in the region. Isolated rain or snow has been forecast for Jammu and Kashmir.

Scattered thundershowers activity is forecast for sub-Himalayan West Bengal, Sikkim and the Northeastern States during the next 4-5 days. This will happen as the eastern flank of the sub-tropical jet allows some of the extra-tropical moisture to filter into the region. Isolated rain/thundershowers are also likely over coastal Orissa, Arunachal Pradesh, Assam, Meghalaya, Nagaland, Manipur, Mizoram and Tripura.

EASTERLY WAVE

Meanwhile, in the south, a retinue of easterly waves is expected to preside over local weather from the Andaman and Nicobar Islands to peninsular mainland. Isolated to scattered rain/thundershowers activity is likely over the Andamans and the extreme south peninsula during the next 3-4 days.

The rains are expected to get better organised from March 8 onwards, according to forecasts by the ensemble forecast system of the Fleet Numerical Meteorology and Oceanography Centre of the US Navy.

The European Centre for Medium-Range Weather Forecasts sees two cyclonic circulations taking shape in the southwest Bay of Bengal, one after the other, and spearheading the wet session to cover more areas of the peninsula.

On Monday, a cyclonic circulation lay over the Lakshadweep area and neighbourhood while a trough of low was present over the southwest Bay of Bengal, off the south Tamil Nadu-Sri Lanka coast.
