Further Details

Heavy rainfall will affect much of the UK this weekend. Rain is expected to develop during Saturday morning across southwest and southern England, becoming particularly heavy and persistent overnight and into Sunday. Accumulations of 50-75 mm are expected to fall fairly widely during this time. There is a chance that some places over Dartmoor could see 100-150 mm. Strong southerly winds will accompany the heavy rain and may locally exacerbate impacts. Rain will become less extensive through Sunday as it erratically clears eastwards.

What should I do?

Check if your property could be at risk of flooding. If so, consider preparing a flood plan and an emergency flood kit.

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.

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.
