Finland: Heatwave forecast to impact portions of southern Finland through at least June 27
Heatwave forecast to impact portions of southern Finland through at least June 27. Localized transport and utility disruptions possible.
Event
Forecast models indicate that a heatwave will persist across portions of southern Finland through at least June 27. As of early June 27, the Finnish Meteorological Institute has issued orange (middle level on a three-tier scale) warnings for extreme heat across Aland, Kanta-Hame, Kymenlaakso, Paijat-Hame, Southwest Finland, South Karelia, South Savo, and Uusimaa regions. Yellow forest fire and extreme heat warnings are in place across the rest of the affected area. Authorities will likely issue new alerts or update/rescind existing advisories, as weather conditions change over the coming days. The extended period of very high temperatures and dry conditions may magnify the potential for wildfires throughout the region.
Health
Heatwaves pose a health 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 risks could also extend to relatively healthy individuals during significant heatwave events. In addition to impacting athletes and those who work outdoors significantly, 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 could warp rail tracks and force passenger and freight trains to operate at reduced speeds. Overheated vehicles could prompt traffic disruptions in urban areas where congestion is already a problem. Commercial trucking disruptions might occur, as very high temperatures put more stress on engines and make 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. Consider remaining indoors in air conditioning when possible, particularly if operating in one of the worst-affected regions. 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 caffeinated and alcoholic beverages, which are dehydrating. 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.
