It will be another windy day with gales in places. Highs at 6 to 10C.

Low pressure remains to the northwest of Scotland on Wednesday. It will be a brighter day for southern Scotland, much of England away from the southeast and for north Wales.

Winds will ease from Tuesday. High temperatures at 5 to 9C.
