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.

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.
