WEATHER forecasters have issued a thunderstorm and tornado alert for Donegal later today.
Irish Weather Online and Met Eireann have both issued alerts with heavy rainfall expected this evening and tomorrow.
Up to 90mm of rain could fall – with winds gusting to 100km/hr.
“A strong cold front will make its away across the country this evening of which will quickly destabilize the air around and showers are expected to form , with strong wind shear (change of wind speed & direction with height ) present,” said IWO.
“Thunderstorms are expected to develop and strong downdrafts with gusts of up to 110km/hr and heavy rain are possible. There is also present, strong low level shear which can lead to supercell characteristics – a rotating thunderstorm – and possible weak tornados.
“This situation will need to be closely monitored. It is likely from reports that a tornado hit Carrickmacross yesterday, so more today is certainly possible with stronger conditions present.”
The forecaster added: “Take extreme caution if travelling this evening , the squally showers alone can be dangerous enough.”
Met Eireann has issued a national Yellow alert from this evening until tomorrow.
