Spain: Heatwave forecast over much of the country through at least July 13
Heatwave forecast over much of Spain through at least July 13. Transport and power disruptions possible.
Event
Forecast models indicate that a heatwave will persist across most of Spain through at least July 13. The Spanish State Meteorological Service (AEMET) has issued a special advisory due to the prolonged hot weather. Temperatures are expected to start building across much of the country July 8-10 and will likely be highest in the Canary Islands and the southwest quadrant of the Iberian Peninsula. The heatwave is expected to last until July 11 in the Canary Islands and July 13 on the peninsula. Temperatures above 37 C (99 F) are likely across much of the Canaries July 9 and temperatures above 40 C (104 F) are possible in parts of the Guadiana and Guadalquivir valleys July 8, most of Extremadura and the entire Guadalquivir Valley July 9, and the Tagus Valley July 10. However, temperature peaks across many parts of the mainland may not arrive until July 11-13.
As of July 8, AEMET has issued heat wave warnings for the following areas:
Orange heatwave warnings (the middle level on a three-tier scale): Parts of western and central Andalusia and western Extremadura autonomous communities.
Yellow heatwave warnings: Parts of western, southern, and northern Andalusia, far southern Castile and Leon, northwestern Castile La Mancha, the rest of Extremadura not under orange warnings, and southwestern Galicia autonomous communities.
Authorities will likely 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 engines, making tire blowouts more common. Major flight disruptions are unlikely at regional airports, but general aviation disruptions are possible; 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.
