Bangladesh: Heatwave conditions forecast to persist over much of the country through at least April 20

Event

Heatwave conditions are forecast to persist across much of Bangladesh through at least April 20. High temperatures have been prevalent across most of the country in recent days, with highs of 41.8 (107.2 F) C recorded in Jashore and Chuadanga in Khulna Division April 16. Highs in Dhaka reached 40.5 C (104.9 F) April 16, the highest recorded temperature in the capital for 58 years. The Bangladesh Meteorological Department has warned that severe heatwave conditions are likely to continue across Khulna Division and parts of Dhaka and Rajshahi divisions for a few more days, with mild-to-moderate heatwave conditions likely over the rest of Bangladesh.

Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. 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. The extended period of oppressive heat and dry conditions may lead to wildfires.

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 vehicles, 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.
