MET Eireann has issued a ‘Status Orange’ alert for Donegal, predicting widespread “very heavy” rain with some thundery downpours tonight.
The wet spell is to persist through tomorrow (Friday), leading to spot flooding and possibly accumulations of 35 mm to 50mm, with up to 70mm possibly on hilly ground and on mountains.
Alerts and warnings are issued whenever weather conditions meeting certain detailed thresholds are anticipated within a 48-hr period.
A ‘Status Red’ severe weather warning is the most serious and means members of the public should “take action.”
The issue of red level severe weather warnings should be a comparatively rare event and implies that recipients take action to protect themselves and/or their properties. This could be by moving their families out of the danger zone temporarily; by staying indoors; or by other specific actions aimed at mitigating the effects of the weather conditions.
The next most serious, ‘Orange’, urges recipients to “be prepared.” This category of weather warnings is for conditions which have the capacity to impact significantly on people in the affected areas.
The third warning, ‘Status Yellow’, means people should “be aware.” The concept behind yellow alerts is to notify those who are at risk because of their location and/or activity, and to allow them to take preventative action.
