Thunderstorm warning is issued for 19 counties, ESB works to restore electricity.

ESB workers attempt to restore electricity to more than 1,000 houses affected by power outages brought on by yesterday's storms, a Status Yellow thunderstorm warning has been issued for Munster, Connacht, and eight other counties.

The Cavan, Donegal, Monaghan, Kilkenny, Laois, Longford, Offaly, Westmeath, Munster and Connacht will be alert until 10 p.m.

According to Met Éireann, the thunderstorms will bring frequent lightning, torrential rain, brisk gusts, and the potential for hail.

The hardest affected areas by yesterday's thunderstorms were in the west, midwest, and midlands, where 5,000 to 10,000 households and businesses lost electricity.

Although workers worked all night, some 1,000 clients are still without power.

The Midlands and Co. Kerry seem to have been the areas most severely impacted; the Valentia Coast Guard had a lightning strike overnight and had to use generators for a while before electricity was completely restored.

Anyone affected by a lightning strike that has resulted in damage or disruptions has been urged to call 1800 372 999 by ESB Networks.

Following floods yesterday in Tralee, University Hospital Kerry is still warning the general public to stay away from its emergency room.

Localized flooding was caused by heavy rain and a thunderstorm in several areas of Kerry, notably Castle Street and Denny Street in Tralee.

A lightning strike near two lifeguards at Banna Beach led to their hospitalization for monitoring, but it is not believed that they were hurt.

According to the Kerry County Council, Banna Beach will not have any lifeguards on duty today.

The route to Glanteenassig Lake near Castlegregory was reportedly stopped due to subsidence even though the floods had abated.

In other locations, from noon to nine o'clock, the UK Met Office has issued a Yellow thunderstorm warning for Antrim, Armagh, Fermanagh, Tyrone, and Derry.
