Fine and mostly dry to start, with any early showers quickly fading. Sunny spells hold on longest in the east. Through the afternoon, cloud and rain tied to Storm Austen push into the southwest, and the wind picks up noticeably by evening. A high of around 15°C.

This is when Storm Austen really arrives, bringing heavy rain and strong winds. Northern parts may get a lull in the wind in the early hours, but gales push into Cornwall around dawn. The temperature drops to about 8°C.

Rain to start everywhere, clearing away to the northeast through the morning. The wind is the headline, staying strong all day with gales along the coast and in exposed spots. Cooler too, with a high of 12°C. Worth allowing extra time if you are out on the roads.
