Sweden: Heatwave forecast across southern Sweden through at least July 22
Heatwave forecast across southern Sweden through at least July 22. Transport and power disruptions possible. Health concerns likely.
Event
Forecast models indicate that extremely high temperatures will persist across southern Sweden through at least July 22. Temperatures of 30-35 C (86-95 F) are forecast across the affected area, with extremely high temperatures of around 35 C (95 F) likely in northeastern Gotaland and southern inner Svealand. Temperatures are likely to peak July 21 before beginning to lower July 22.
As of early July 20, the Swedish Meteorological and Hydrological Institute (SMHI) has issued orange high temperature warnings (the middle level on a three-tier scale) across northeastern Gotaland and southern inner Svealand through July 22. Yellow high temperature warnings are in place over the rest of the affected area over the same period.
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.
