Thunderstorm Warning Issued for Cork

Met Éireann has issued a yellow weather warning for thunderstorms affecting Cork and Waterford counties, with heavy showers and localised thunderstorms expected from late Wednesday evening into Thursday morning.

The warning, issued at 11:37 on Wednesday, 11th June 2025, comes into effect at 22:00 tonight and will remain in place until 03:00 on Thursday, 12th June.

What to Expect

Residents in the affected areas should prepare for heavy downpours accompanied by thunderstorms that may develop locally throughout the warning period. The meteorological service has highlighted two primary concerns:

Spot flooding is possible as intense rainfall over short periods can overwhelm drainage systems, particularly in urban areas and low-lying regions. Drivers should exercise extra caution on roads where water may accumulate quickly.

Lightning damage poses another risk during the thunderstorm activity. Electrical equipment and outdoor structures could be affected, and residents are advised to avoid unnecessary outdoor activities during peak storm periods.

Areas Affected

The warning specifically covers Cork and Waterford counties, where conditions are expected to be most severe. Neighbouring counties should monitor updates as thunderstorm patterns can be unpredictable and may shift slightly.

Safety Advice

Local authorities recommend staying indoors during the most intense periods of the storm, ensuring mobile devices are charged in case of power interruptions, and avoiding elevated outdoor areas where lightning strikes are more likely.

The relatively short duration of the warning suggests the weather system will move through fairly quickly, with conditions expected to improve by Thursday morning.
