Rain warning of yellow

Yellow warning of rain

Be aware

Valid from 16:00 on Sunday until 23:50 on Sunday

Although not all areas will be affected, thundery showers are likely to affect some southeastern parts of England later on Sunday. Lightning may be an additional hazard. The public should be aware of the risk of localised impacts from heavy rain and flooding, which may affect travel and some outdoor events. This is an update to the warning issued on Saturday, to reduce the area at risk from the thundery downpours whilst delaying the start time.

Chief Forecaster's assessment

A complex frontal system will remain slow-moving from southwest to eastern England during Sunday. Warm, humid air on the southeast of this boundary is likely to become the focus for thundery activity imported from northern France during the late afternoon and particularly the evening, leading to localised torrential downpours. As often in these situations, some places will miss the worst, but a few places may see 30 to 50 mm of rain in total, with hourly totals very locally above 20 mm.

Rain warning of yellow

Yellow warning of rain

Be aware

Valid from 01:00 on Monday until 17:00 on Monday

Further areas of heavy rain or thundery showers are likely to affect parts of southeastern England and East Anglia at times on Bank Holiday Monday. The main risk periods would seem to be before dawn and again during the middle of the day and into the afternoon. The evening should see a slow transition to drier conditions from the west. This update slightly reduces the northwestern extent of the area at risk from thundery downpours, and brings forward the end time of the warning. Given continuing complexities, a further update to the Warning is likely to be issued early on Monday. The public should be aware of the risk of further localised flooding and impacts on holiday activities.

Chief Forecaster's assessment

Parts of East Anglia and southeast England will still be affected by a warm, humid and unstable airmass during much of Monday, which leaves the opportunity for thundery downpours to spread from Northern France. As in many such cases, only a minority of places will see the heaviest rain, but there is a chance that some locations could see 20 to 25 mm of rain in an hour and perhaps 40 mm in a few hours.
