Spain: High temperatures forecast to persist over southern and eastern regions through at least Aug. 20
High temperatures forecast to persist over southern and eastern Spain through at least Aug. 20. Transport and power disruptions possible.
Event
Forecast models indicate high temperatures will persist across parts of southern and eastern Spain, including the Balearic Islands, through at least Aug. 20. As of early Aug. 17, the Spanish State Meteorological Service (AEMET) has issued orange high-temperature warnings (the middle level on a three-tier scale) across central Aragon, northern Basque Country, La Rioja, and southern Navarre autonomous communities Aug. 19; temperatures of up to 39 C (102 F) are forecast. Yellow high-temperature warnings are in effect across most of the rest of the affected area through Aug. 20. Authorities will probably issue new alerts or update/rescind existing advisories as weather conditions change over the coming days.
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 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.
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.
