Further rainfall on Monday and into Tuesday may lead to some flooding and disruption

Effective: Thu January 1, 1970, 1:00 AM
Expires: Tue February 3, 2026, 9:00 AM

Whilst there is some uncertainty, outbreaks of rain may become persistent on Monday, especially later in the day and overnight, before gradually easing and clearing into Tuesday. Accumulations of 10-20 mm are possible fairly widely, with perhaps as much as 30-50 mm over Dartmoor. Given saturated ground following recent rain, there is a chance this may leading to some flooding and disruption in places. 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.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
