Myanmar: High temperatures forecast to persist across much of the country through at least mid-May

High temperatures are forecast to persist across much of Myanmar through at least mid-May. Authorities recorded the country's highest-ever April temperature of 48.2 C (118.8 F) in Chauk in Magway Region on April 28, and temperatures over 40 C (104 F) have been recorded in many parts of the country in recent days. Myanmar's Department of Meteorology and Hydrology has observed temperatures of 5-6 C (9-11 F) above the April average in Sagaing, Mandalay, Magway Regions and Shan State April 29-30 and 2-4 C (4-7 F) above the April average across much of the rest of the country, with the exception of Kachin State. Temperatures of 34-44 C (93-111 F) are forecast across much of the country May 1-3, and the high temperatures are expected to persist over the coming weeks.

The extended period of oppressive heat and dry conditions may produce ideal circumstances for wildfire growth throughout the region. Heatwaves also threaten 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 during prolonged exposure to high temperatures. These health risks could also extend to relatively healthy individuals during significant heatwave events. In addition to significantly impacting athletes and those who work outdoors, high temperatures can cause problems for people using mass transit. The lack of air conditioning and cramped vehicles during rush hour may lead to some passengers' hospitalization.

Very high temperatures may damage road surfaces, 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 regional airports, 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.
