India: Severe heatwave to persist in northwestern, central, and eastern regions through May 2
Severe heatwave to persist in northwestern, central, and eastern India through May 2. Transport, utility, and power disruptions possible.
Event
A heatwave is forecast to persist across much of northwestern and central India through at least May 2 and parts of eastern India through at least April 30. The India Meteorological Department (IMD) has forecast heatwave conditions in isolated pockets over western Rajasthan April 28-30 and severe heatwave conditions in the region May 1-2. Heatwave conditions are also expected in some or isolated parts of Vidarbha, western Uttar Pradesh, Madhya Pradesh, Punjab, Haryana, Chandigarh, Delhi, and eastern Rajasthan April 28-May 2, as well as eastern Uttar Pradesh and Telangana April 28-May 1, Bihar, Jharkhand, interior Odisha, Chhattisgarh, and Gangetic West Bengal April 28-April 30, and Gujarat State April 28. A rise in temperatures of 2 C (3.6 F) is likely in northwestern regions April 28-29, with no significant rises expected over the rest of the country; however, temperatures have already reached 40-45 C (104-113 F) in recent days across parts of the country.
The IMD has issued orange heatwave warnings (the middle level on a three-tier scale) for western Rajasthan April 28-29 and May 1-2, as well as for Madhya Pradesh and Vidarbha April 30-May 2. Yellow heatwave warnings have been issued across the rest of the affected area for various days between April 28-May 2. Yellow dust storm warnings have been issued for Punjab, Haryana, Chandigarh, Delhi, Uttar Pradesh, and Rajasthan April 30. Authorities will likely amend advisories as weather conditions change over the coming days.
The surging power demand triggered by the prevailing heatwave has led authorities in Rajasthan, Gujarat, and Andhra Pradesh to schedule power cuts in factories and some rural regions in order for electricity supply to attempt to keep up with the heightened demand. Further power cuts and outages are likely across the affected regions whilst the extreme temperatures persist.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the affected regions. Heatwaves pose a threat to vulnerable groups - such as the elderly, children, pregnant women, and those with respiratory illnesses - due to the increased possibility of heat stroke or heat exhaustion. Relatively healthy individuals, especially those working outdoors or using mass transit, may also face health risks during significant heatwaves. The lack of air conditioning and cramped vehicles, particularly during rush hour, may lead to dehydration and other health issues in some passengers.
Transport and Utilities
Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speed. Road surface damage is also possible, and overheated vehicles may worsen traffic problems in urban areas where congestion is already a problem. Commercial trucking disruptions might occur as very high temperatures put more stress on engines, making tire blowouts more common. Major flight disruptions are unlikely at airports in the region, but general aviation disruptions are possible, and some airfreight carriers could reduce cargo loads. High temperatures could lead to an increased demand for electricity, which might trigger localized brownouts or blackouts, exacerbating hazardous conditions when air conditioning is no longer possible.
Advice
Monitor local media for weather updates and related advisories. During heatwaves, remain indoors in air conditioning when possible. If outdoor activities are necessary, frequently rest in shaded areas; avoid activity during the hottest times of the day. Stay well hydrated by drinking plenty of fluids. Avoid alcoholic beverages, which are dehydrating; drink bottled water or water that has been boiled. Wear loose-fitting, light-colored clothing. Cotton fabrics are more cooling than synthetics. Promptly seek medical attention if signs of heat exhaustion or heat stroke develop. Charge battery-powered devices in case prolonged electricity outages occur. Reconfirm ground and rail transport services.
