Orange thunderstorm alert issued for Galway, Mayo and Roscommon amid heatwave and storm damage in Ireland

Met Éireann issued a Status Orange thunderstorm warning for Galway, Mayo and Roscommon after Ireland’s short heatwave gave way to severe and highly localized storms.

The warning covered a four-hour window from 5pm to 9pm on June 26 and came after weather conditions turned increasingly unstable across the west and northwest. Reporting said the storms brought a risk of flooding, hail, difficult travelling conditions and damage to utilities.

Temperatures had already climbed to 31.7C in Athenry, Co Galway, on June 25 before the thunderstorm threat escalated.

Heatwave to thunderstorms

The Irish weather pattern shifted quickly from hot and settled to storm-prone air. Earlier on June 26, Met Éireann had placed 22 counties under a Status Yellow thunderstorm alert, underlining how widespread the unstable conditions had become.

The later orange warning was focused on Galway, Mayo and Roscommon, where the most severe impacts were expected. The public was warned that power, water, gas and telecommunications could all be affected.

The storm risk was described as highly localized or hit and miss, but the hazards were serious where cells developed. Lightning, hail and sudden downpours created the main threat, especially for people travelling or spending time outdoors.

Outages and disruption

Reporting said about 8,000 homes and businesses lost power as the thunderstorms moved through. That made the event more than just a weather warning, with the potential for knock-on disruption to households, businesses and emergency response.

The warning also flagged travel hazards from flooding and poor visibility. Roads could become difficult quickly if intense rain fell over a short period.

Beaches were also reported to have been crowded during the heat spell before conditions deteriorated, showing how fast the public-safety picture changed from heat to severe weather.

Galway tornado report

Later coverage said a tornado was confirmed in Galway near Athenry and Oranmore during the orange thunderstorm alert. That added another severe-weather dimension to an already volatile evening.

The tornado report followed the earlier heat peak in Athenry and the same-day escalation in thunderstorm warnings. It reinforced how localized but intense the storm impacts were in parts of the west.

What happens next

The key questions now are whether Met Éireann extends or ends the warning as scheduled, whether ESB Networks updates the outage total, and whether local authorities or emergency services report further disruption.

Officials and forecasters will also be watched for any formal assessment of the Galway tornado and for any reports of injuries, road closures or transport disruption linked to the storms.
