Expires: Sat January 31, 2026, 6:00 AM

Outbreaks of rain, heavy at times, are expected to arrive across Cornwall on Friday morning and move northeastwards across other parts of southwest England by afternoon, followed by showers during Friday evening and overnight into Saturday morning. 10 to 20 mm rainfall is likely widely, with up to 30 mm possible over the moors and perhaps west Cornwall. Falling on saturated ground, this may lead to some flooding and disruption. Strong winds are also likely 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. 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.
