Belgium: Heatwave forecast over much of the country through at least June 21
Heatwave forecast over most of Belgium through at least June 21. Transport and power disruptions possible.
Event
Forecast models indicate that a heatwave will persist across most of Belgium through at least June 21. The Royal Meteorological Institute (RMI) has issued a heat warning covering the period June 16-21 due to the expected rise in temperatures. Temperatures of up to 29-31 C (84-88 F) are expected across the plains June 17. Temperatures are expected to peak June 18, with maximum of 33-34 C (91-93 F) likely across the plains and 35-36 C (95-97 F) possible in the Gaume region in the southeast and Campine region in the northeast. Only coastal areas are expected to be spared from the extreme temperatures, with maximums only reaching around 25 C (77 F). Temperatures are expected to begin to cool across much of the country from June 19; however, it will remain around 30-32 C (86-90 F) in parts of the southeast. Temperatures may remain high across eastern areas June 20-21.
As of June 16, the RMI has issued orange heat warnings (the middle level on a three-tier scale) for Luxembourg Province June 17-18 and yellow heat warnings for the rest of the country, with the exception of coastal areas. The RMI will likely update the warnings over the coming days, with further warnings expected June 19 when temperatures are likely to peak. Authorities are advising the public to stay hydrated, avoid prolonged exposure to direct sunlight, and wear light and loose-fitting clothing.
Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for additional wildfire growth throughout the region. Heatwaves also 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 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 being hospitalized for dehydration.
Transport and Utilities
Very high temperatures may warp rail tracks and force passenger and freight trains to operate at reduced speeds. 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 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.
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 water that is bottled or 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.
