Weather Alerts

Further rain is expected and may lead to more flooding and transport disruption.

South West England
Severity: Moderate Urgency: Future

A band of rain is likely to reach southwest England on Thursday afternoon then spread quickly northeast across the rest of the warning area by evening. The rain is only likely to last for a few hours in any one location but will be heavy at times. A further 10 to 20 mm is likely quite widely, and in the wetter spots, particularly across the moors, a further 20 to 40 mm is possible and will fall onto already saturated ground. 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.

Event: Yellow rain warning Certainty: Possible Category: Met

Further rain on Thursday afternoon to early Friday is expected to lead to some transport disruption and exacerbate flooding in places: UPDATED

London & South East England | South West England
Severity: Moderate Urgency: Future

Information on update: Rainfall amounts are expected to be slightly lower and the impact level has been decreased. The warning end time has been extended slightly later whilst the eastern boundary has also been adjusted. A band of rain will arrive across Cornwall on Thursday afternoon then move northeast across the warning area through the evening and clearing during early Friday. The rain is only likely to last for a few hours in any one location but will be at heavy at times. A further 10-15 mm of rain is expected fairly widely, but some locations, most likely in the south of the area, could see 20-25 mm. The likelihood of impacts from these rainfall amounts is higher than normal due to saturated ground and ongoing flooding following Storm Chandra.
