MeteoGalicia on Wednesday, 26 August 2026, has activated a yellow warning level (Aviso amarillo) for heavy rain in the province of Pontevedra and parts of the province of A Coruña . According to the regional weather service, locally heavy showers and isolated thunderstorms are expected overnight into Thursday. MeteoGalicia gives a threshold of local rainfall intensities exceeding 15 l/m² in one hour.
According to the bulletin, the warning covers the west, south-west and inland areas of the province of A Coruña, as well as the coastal zone of Pontevedra. The main risk is overnight; the more intense periods are expected in one- to three-hour windows. The regional information is consistent with a report by Europa Press on Wednesday morning, which announced the activation of the warning level in the early hours of Thursday in Galicia .
The weather trigger is an Atlantic disturbance bringing moist, unstable air into north-western Spain . AEMET forecasts an increased likelihood of thunderstorms and heavy rain in north-west Spain over the same period, but stresses that regional services are responsible for defining warning areas in detail. For Galicia, MeteoGalicia provides the authoritative, geographically detailed information on affected areas and time windows.
Short-lived heavy rain can flood basements and underpasses, reduce visibility on roads and disrupt traffic on coastal and inland routes. In such conditions, municipal services typically focus on checking drainage systems and maintaining emergency response cover. Residents are advised to follow local official information channels and, where possible, postpone journeys during heavy rainfall. These are precautionary measures; at the time of publication, no reliable information was available about actual damage or disruption.
All times refer to the night from Wednesday into Thursday, based on the information published by MeteoGalicia on Wednesday morning. Forecasts depend on how the disturbance develops and may change as warnings are updated. For affected places, the specific time windows and areas issued by MeteoGalicia for Pontevedra and A Coruña are key.
