Storm Amy will bring a period of strong and gusty winds to parts of England and Wales on Saturday
Effective: Thu January 1, 1970, 1:00 AM
Expires: Sat October 4, 2025, 7:00 PM
West to southwesterly winds will strengthen and become rather gusty on Saturday, with gusts of 45-55 mph possible in places, and perhaps 60-65 mph along some exposed coasts, especially in the west, and briefly over more exposed hills inland.

Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary. People cope better with power cuts when they have prepared for them in advance. It’s easy to do; consider gathering torches and batteries, a mobile phone power pack and other essential items. If you are on the coast, stay safe during stormy weather by being aware of large waves. Even from the shore large breaking waves can sweep you off your feet and out to sea. Take care if walking near cliffs; know your route and keep dogs on a lead. In an emergency, call 999 and ask for the Coastguard. Be prepared for weather warnings to change quickly: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
