Andorra Issues Storm Alerts and Extreme Heat Warnings up to 35°C

Andorra's Meteorological Service has issued yellow alerts for intense thunderstorms today alongside yellow and orange heat warnings nationwide through Monday, with temperatures expected to reach "extremely high" peaks of 35°C.

The yellow storm alert covers the entire country from midday until 9pm, bringing risks of heavy downpours over 5mm in 30 minutes, lightning, and showers fueled by high pressure, cool upper air, daytime heating, and lingering moisture. Sunny starts will give way to afternoon cloud development and possible isolated showers. Today's highs hit 31-32°C in Andorra la Vella, 26-27°C at 1,500m, and 16-17°C at Pas de la Casa, with limited overnight cooling under high clouds from southern Catalonia.

Heat warnings activate tonight. Northern areas face a yellow alert from noon tomorrow, while central and southern zones shift from yellow—active since 9am today—to orange from noon tomorrow through Monday. The weekend promises sunny conditions with high clouds and Saharan dust haze curbing visibility and nighttime relief, intensifying valley heat. Friday clears to mostly sun after scattered clouds, reaching 30°C in the capital, 25°C at 1,500m, and 15°C at Pas de la Casa.

Saturday stays warm and summery under dominant sunshine despite high clouds, with peaks of 30°C in Andorra la Vella, 26°C at 1,500m, and 16°C at Pas de la Casa. Sunday ramps up to 34-35°C in the capital, 29-30°C at 1,500m, and 19-20°C at Pas de la Casa, amid weak southwest winds, persistent high clouds, and potential afternoon showers that won't temper evening warmth. Monday delivers the hottest conditions at 34-35°C in Andorra la Vella, 30-31°C at 1,500m, and 19-20°C at Pas de la Casa, with no afternoon rain prolonging the heat.

Central and southern valleys below 1,100m will meet heatwave criteria through Tuesday, with highs possibly exceeding 32°C, while northern spots like Ransol stay milder around 26°C. Wednesday around Sant Joan may see slight cooling from afternoon showers, though full normalization could wait until next weekend.

Civil Protection's heat pre-alert runs from Saturday, peaking Sunday-Monday. Guidance stresses frequent hydration, light clothing, head cover, avoiding peak-hour exertion, and seeking air-conditioned areas. Close sun-facing windows and shutters by day, open at night, stick to cooler home zones, and opt for light meals. Infants require regular fluids, shade, light attire, and head protection; daily check-ins are vital for elderly or ill individuals living alone. Civil Protection and Social Affairs have shared tailored self-protection advice with day centers, retirement homes, socio-health facilities, and other entities. Pet owners should ensure shade and water access.
