A thunderstorm is moving across the Algarve this Sunday afternoon (October 18), travelling from the northeast towards the west of the region.
The Portuguese Institute of the Sea and Atmosphere (IPMA) has warned of potentially heavy showers, thunderstorms and hail, with strong gusts of wind also possible.
Residents and motorists are advised to exercise caution, particularly in areas affected by heavy rainfall and sudden changes in weather conditions.
More rain forecast for Monday
According to weather website Meteored, the latest forecasts from the European Centre for Medium-Range Weather Forecasts (ECMWF) suggest that unsettled conditions will continue into Monday (October 19).
Light rain is expected in the Algarve between midday and 6pm, with the probability of precipitation reaching around 60% in some areas during the afternoon.
The forecast suggests that the rain will then shift towards northern Portugal, reaching the northern coast late on Tuesday (October 20) before spreading towards central coastal areas overnight.
Cloudy skies are expected across much of mainland Portugal on Tuesday and Wednesday, with temperatures remaining typical of autumn or slightly below seasonal averages.
In the Algarve, temperatures are forecast to remain relatively mild, although Faro could see readings of around 17°C on Monday afternoon.
