Parts of Britain are being battered by strong winds as the remains of Hurricane Katia sweep in.
There are warnings that the storms could damage buildings and blow down trees.
Train services are being affected and some ferries have been cancelled.
Katia started in the Atlantic Ocean and passed near America and Canada before heading towards Britain.
Southern and central parts of Scotland, Northern Ireland, and northern England and Wales are all being hit.
Winds of up to 80 miles per hour and heavy rain are expected in many areas.
The bad weather could last for several days.
