Thiruvananthapuram, April 30 The mercury crossed the 47 degree Celsius mark at Nagpur in the Vidarbha region, prompting some international weather models to scale up the expected highs by another notch as early as on Friday.

This, even as some others signalled that the 50 degree Celsius mark may be reached in the interior parts of the region bordering Orissa and North Andhra Pradesh during the period up to May 4.

The heat wave is being triggered by the hot air steered by the seasonal anti-cyclone (high-pressure area with sinking and compressed air) extending from North Africa and West Asia through Pakistan.

Heating has already reached all-time highs at many places led by Nagpur; in Bhopal, the all-time high has been equalled.

In Delhi, the 43.5 degree Celsius recorded on Thursday was the highest in 50 years.

There is no let up indicated either with India Meteorological Department (IMD) warning that the heat wave will continue to take a stranglehold of entire North, Northwest, Central and adjoining East-Central India.

Current meteorological analysis suggests that heat wave conditions are likely to continue for another two days and also extend into parts of Marathwada, Telangana and southeast Uttar Pradesh. International models say the heat wave would last longer.

The IMD said that severe heat wave conditions will largely hold over many parts of Rajasthan.

Heat wave conditions are expected to continue over Madhya Pradesh, Chhattisgarh, Vidarbha and Delhi.

Parts of Punjab, Haryana, west and south Uttar Pradesh, Telangana, madhya Maharashtra, Marathwada, interior Orissa, Jharkhand and Jammu division of Jammu and Kashmir will also be under the grip of the heat wave.

Arrival of a western disturbance over Northwest India on May 3 might help relieve the situation somewhat but might be reversed sooner than later as the westerly system moves away into the east-northeast.

Meanwhile, a north-south trough lay extended from sub-Himalayan West Bengal to North Bay of Bengal. Under its influence, scattered to fairly widespread rain or thundershowers are likely over the Northeastern States during the next three days.

In the south, the Regional Met Centre, Chennai, said in its update that heat wave conditions prevailed over parts of Telangana during the 24 hours ending on Thursday morning.

Rainfall occurred at a few places over Kerala and isolated rainfall occurred over Tamil Nadu, Lakshadweep and Karnataka. Adilabad in north Andhra Pradesh recorded the highest maximum temperature of 46 degree Celsius in the region.
