The record-breaking heatwave has forced cities in the western US and Canada to open cooling centres, hand out bottles of water and hats. The scorcher is being blamed on a high-pressure "heat dome" trapping warm air in the region
The chilling report by the UN's climate science advisory panel paints a grim -- and deadly -- picture for a warming planet. If the world warms by 1.5 degrees Celsius -- 0.4 degrees above today's level -- 14 percent of the population will be exposed to severe heatwaves at least once every five years, "a significant increase in heatwave magnitude", the report says.
Rainfall over the country as a whole for the month of May 2021 shows that it has recorded 107.9 millimetres which is 74 per cent more than its Long Period Average (LPA) of 62 mm.
The India Meteorological Department (IMD) issued a red alert for Mumbai, and neighbouring Thane, Palghar and Raigad districts, warning of very heavy to extremely heavy rainfall at isolated places there during the day.
The monsoon onset over Kerala marks the commencement of the four-month rainfall season in the country.
Names suggested by 13 countries are used sequentially when a cyclone develops in the Indian Ocean.
Thunderstorms with lightning and gusty winds (speed reaching 30-40 kilometres per hour) are very likely at isolated places over Telangana, Kerala and Mahe from April 26.
Visibility at Palam dropped from 3,000 metres to 500 metres due to the dust storm. At Safdarjung, it was reduced from 2,200 metres to 1,500 metres.
The researchers noted that more rainfall is not necessarily a good thing for the farming sector in India and its neighbouring countries.
The Safdarjung Observatory, which provides representative data for the city, recorded a maximum temperature of 40.1 degrees Celsius, which was eight notches more than normal, said Kuldeep Srivastava, the head of the IMD's regional forecasting centre.
Scientists, including those from Oak Ridge National Laboratory in the US, said such an increase in extreme heat events can create unsafe labour conditions in major crop producing parts of India, such as Uttar Pradesh and West Bengal, as well as coastal regions and urban centres like Kolkata, Mumbai, and Hyderabad.
Kashmir is currently under the grip of ''Chillai-Kalan'' -- the 40-day harshest winter period when a cold wave grips the region and the temperature drops.
The convergence of moist easterly winds from the Bay of Bengal and southwesterly winds from the Arabian Sea is likely to continue over northwest India for another two-three days, weather experts said.
The orange alert by the IMD's Mumbai centre is also for coastal districts like Raigad, Ratnagiri, Sindhudurg as well as Pune in western Maharashtra.

The districts of East Midnapore, West Midnapore, South 24 Parganas, North 24 Parganas and Howrah are likely to receive heavy rain tomorrow, Regional met director G K Das said.
