Irish weather service extends fog alert: 12 counties face reduced visibility

Met Éireann declared a yellow fog warning for twelve counties in the Republic of Ireland on Sunday night. The alert covers Donegal, Cavan, Monaghan, Louth, Meath, Westmeath, Longford, Galway, Leitrim, Mayo, Roscommon, and Sligo. Visibility is expected to be poor, making travel difficult in these regions.

The warning takes effect at 9 p.m. on Sunday and lasts until 11 a.m. on Monday. This timing places the heaviest impact on commuters as the work week begins. A yellow warning indicates conditions that are not especially unusual but present a localized danger.

This alert follows a similar warning issued the previous night, which covered twenty-five counties. That prior alert included the entire state except for Donegal. On Sunday, the day was expected to be dry overall after earlier patches of fog and mist lifted in affected areas. Patches of rain were expected from the southwest in areas not covered by the fog warning on Sunday night.

The UK Met Office did not issue a corresponding warning for the region. Forecasters predict the week will begin milder and wetter. Rain and drizzle are expected to roll in from the south on Monday night.

Heavier rain is possible on Tuesday and Wednesday. Cooler and brighter conditions are forecast to prevail by the end of the week.
