Andorra Issues Yellow Thunderstorm Alert with Hail Risk from 3pm

A moderate-risk yellow alert warns of afternoon thunderstorms triggered by cooler upper air easing recent heat. Expect intense downpours, lightning, and possible hail, heaviest in the east, urging caution outdoors.

Key Points

  • Cooler upper air triggers convective clouds, heavy showers, lightning, and strong gusts.
  • Conditions improve from Monday with high pressure and rising temperatures.
  • Civil Protection advises securing balcony items, avoiding outdoors during storms, and sheltering from lightning.
  • Follows Saturday's flooding in Pas de la Casa after previous yellow alert.

Andorra's Meteorological Service has issued a yellow alert for thunderstorms this Sunday afternoon, forecasting locally intense showers across the Principality.

Cooler upper air is expected to trigger convective cloud development, leading to heavy downpours accompanied by lightning and strong wind gusts in various areas. The alert focuses on afternoon instability, with conditions set to improve from Monday as high pressure returns, bringing meteorological stability and rising temperatures.

Civil Protection advises securing items on balconies and terraces to guard against wind, avoiding outdoor activities during storms, and seeking shelter indoors when lightning occurs. Those outside should steer clear of metal objects, while vulnerable individuals are urged to limit exposure until the weather settles.

This follows Saturday's frontal system, which caused heavy rain and flooding in Pas de la Casa. Firefighters and Civil Protection cleared waterlogged streets then under a previous yellow alert for storms, lightning, and small hail—activated Friday amid irregular showers mainly in the east. That event followed heat peaking at 33°C in Andorra la Vella. Sunday conditions had eased earlier, with highs of 25°C in Andorra la Vella, 22°C at 1,500 metres, and 14°C at Pas de la Casa.

Civil Protection recommends staying informed as conditions evolve.
