While the weather outlook for St Patrick's Day is for a dry day with good sunny spells, motorists are advised of foggy conditions early tomorrow morning.
Met Eireann has issued a status yellow fog warning for Connacht, from 3am to 9am tomorrow morning, and says foggy conditions will lead to reduced visibility.
However, the fog will clear quickly to give a mostly dry and sunny day, but cloud will build through the afternoon, with some outbreaks of patchy light rain or drizzle possible along the coast towards evening.
Temperatures tomorrow a mild 11-14 degrees in light breezes.
