"There will be strong northeasterlies in places for most of the week until Thursday end. On Friday the region can expect a break in the rain and strong winds.
"There are no heavy rain watches or warnings in place, but that can change."
She said the nights, because of the northeasterly flow and rain, were expected to be warm and muggy.
