Central Europe: High temperatures forecast to persist across parts of Austria, Czech Republic, Germany, Poland, and Slovakia through at least June 22

Event

High temperatures are forecast across parts of central Europe through at least June 22. The affected areas include parts of Austria, the Czech Republic, Germany, Poland, and Slovakia. Temperatures of up to 35 C (95 F) are possible in parts of Austria, Germany, and Slovakia and 32 C (90 F) in parts of the Czech Republic and Poland through June 22, before the heat begins to abate from June 23.

As of June 20, Austria's Central Institution for Meteorology and Geodynamics (ZAMG) has issued yellow heat stress warnings across the country June 20. Orange warnings are in place for parts of eastern, northern, and southern Austria for June 21, with yellow warnings across the rest of the country. The orange warnings become more widespread across most of the country on June 22, with the few remaining areas under yellow warnings.

The Czech Hydrometeorological Institute issued yellow high temperatures warnings across central, northwestern, southern, and western regions on June 20. An outlook for dangerous phenomena message for high temperatures has also been issued for June 21-22.

The German Meteorological Service (DWD) has issued the lowest of two levels of heat warnings across most of central and southern Germany June 20-21. Further high temperatures are forecast across much of the country on June 22, with slightly cooler conditions possible in coastal regions.

Poland's Institute of Meteorology and Water Management (IMGW) has issued orange heat warnings (the middle level on a three-tier scale) across Greater Poland, Kujawy-Pomerania, and Opole provinces, most of Lesser Poland, Lower Silesia, and Silesia provinces, and parts of western Mazovia Province June 20-21. Yellow heat warnings are in place across Lodz and Lubuskie provinces, the rest of Lesser Poland, Lower Silesia, and Silesia provinces, and parts of southern Pomerania and southern West Pomerania provinces.

The Slovak Hydrometeorological Institute issued yellow high-temperature warnings for western regions on June 20 and southern and western regions on June 21. Orange warnings are in place for western regions on June 22, as well as yellow warnings for southern and west-central regions.

Officials could update and possibly extend the coverage of weather alerts over the coming days.

The high temperatures may result in increased energy and water demand and a heightened risk of heat-related illnesses, such as heat exhaustion and heat stroke.

Hazardous Conditions
The extended period of oppressive heat and dry conditions may produce ideal circumstances for 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.

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 stress vehicles, making tire blowouts more common. Major flight disruptions are unlikely, 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 heat waves, 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.
