Heavy rain may bring some flooding and travel disruption in places on Monday night into Tuesday morning: UPDATED
Effective: Thu January 1, 1970, 1:00 AM
Expires: Tue December 9, 2025, 2:00 PM
Information on update: The warning end time has been brought forward. Outbreaks of rain will become persistent and heavy on Monday night into Tuesday morning. There will naturally be some variation in rainfall totals across the area, but accumulations of 20-40 mm are likely in quite a few places, with 60-80 mm over Dartmoor and high ground in Wales. There is a chance of up to 100 mm falling over the most exposed, prone hills. Given the saturated nature of the ground, this is likely to lead to some flooding in places and transport disruption. Rain will also be accompanied by strengthening southerly winds, which may exacerbate impacts. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings
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.
Strong winds may cause some disruption on Monday night into Tuesday
Effective: Thu January 1, 1970, 1:00 AM
Expires: Tue December 9, 2025, 4:00 PM
South to southwesterly winds will strengthen on Monday night and remain strong and gusty into Tuesday morning, before gradually easing through Tuesday afternoon. Peak gusts of 40-50 mph are expected fairly widely, but gusts of 60-70 mph will be possible along some exposed coasts and over/to the north of high ground. There is a small chance of gusts in excess of 70 mph over northwest Wales. For further details see https://www.metoffice.gov.uk/weather/warnings-and-advice/uk-warnings

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.
