India Meteorological Department (IMD) has indicated the possibility of a flare-up in mercury conditions over the western parts of the country later this week.
It further warned that heat wave conditions may develop over isolated pockets of west Rajasthan and Gujarat, which have for sometime now been made to take on an invading area of high pressure (ridge) from across the border in West Asia.
This would mean that a fresh western disturbance making its way into the northwest after a hiatus may not be able to make an impression to the building heat towards south-southwest of its expected track.
But maximum temperatures during the day on Monday were below normal by 4 to 6 deg Celsius over parts of
northwest and west India and by 2 to 3 deg Celsius over parts of central India, the IMD update said.
The highest maximum of 40.5 deg Celsius was recorded at Barmer in Rajasthan.
Otherwise, the day saw widespread rainfall being reported from Andaman and Nicobar Islands as clouds kicked up by an erstwhile easterly wave and a persisting upper air cyclonic circulation over southwest Bay of Bengal liquidated themselves.
The rain was isolated over Tripura, as a trough in the lower levels of the atmosphere hung over Gangetic West Bengal to link north Andhra Pradesh through Orissa.
Satellite pictures early on Tuesday morning showed the presence of convective clouds over parts of south Bay of Bengal and Andaman Sea.
IMD forecast valid until Friday suggested that widespread rain or thundershowers would continue to occur over Andaman and Nicobar Islands.
Isolated rain or thundershowers has been predicted for the Northeastern States, West Bengal, Sikkim, Orissa, coastal Andhra Pradesh, Tamil Nadu, Kerala and Lakshadweep until Wednesday.
Fairly widespread rain or snow would occur over Jammu and Kashmir and scattered over Himachal Pradesh and Uttarakhand on Thursday and increase thereafter.
Extended forecast until Sunday said that fairly widespread rain or thundershowers would occur over Andaman and Nicobar Islands and the Northeastern States while being scattered over extreme south peninsular India.
Fairly widespread rain or snowfall is likely over Jammu and Kashmir, Himachal Pradesh and Uttarakhand
