NEW DELHI: There appears to be no early respite for residents of Chennai and those living in other parts of coastal Tamil Nadu and Andhra Pradesh, as the India Meteorological Department (IMD) has forecast that the heat wave conditions over the coastal areas of the two States for over a week now may continue for two more days.
Speaking to The Hindu, an IMD spokesperson said there appeared to be no possibility of any change in the weather conditions, as there seemed to be no indication of any movement of the monsoon.
The monsoon current, remaining stationary since May 11 after advancing into the Andaman Sea and the south-east Bay of Bengal about a week earlier than the normal date of onset over these area, is likely to stay put at least for another two days.
Mathematical models showed that a vortex could develop over the Arabian Sea in the coming days and thus help the monsoon to move forward. But, these were only early indications. One has to wait and watch, the spokesperson said.
Consequently, the expectation, he said, was that the westerly and north-westerly winds will continue to blow, bringing hot and dry air from the north-west and western regions to the coastal areas of Tamil Nadu and Andhra Pradesh and at the same time blocking the sea breeze from setting in. There was, however, a possibility of more rain over the extreme southwest peninsular region.
Under the influence of a western disturbance as an upper air system, scattered rain or thundershowers are likely over the western Himalayan region during the next 48 hours. Isolated to scattered rain/thundershower accompanied with squall is also likely over the plains of northwest India during the same period.
Isolated thunder-squalls are likely to occur over Delhi, Haryana, Chandigarh, Punjab, Himachal Pradesh, Jammu division of Jammu and Kashmir, Uttarakhand, Rajasthan, Uttar Pradesh, Bihar, Jharkhand, Orissa, West Bengal and Sikkim, while isolated heavy rainfalls are likely over Nagaland, Manipur, Mizoram, Tripura, Assam and Meghalaya after 24 hours.
