Yellow warning of rain

Updated 25 May at 12:25 BST

From:06:00 BST on Sat 26 MayTo:23:59 BST on Sun 27 May

Headline: Heavy showers and thunderstorms will affect parts of Southern Britain this weekend.

What To Expect: There is a small chance that homes and businesses could be flooded quickly, with damage to some buildings from floodwater, lightning strikes, hail or strong winds.

There is a small chance of fast flowing or deep floodwater causing danger to life.

Where flooding or lightning strikes occur, there is a chance of delays and some cancellations to train and bus services.

Spray and sudden flooding could lead to difficult driving conditions and some road closures.

There is a small chance that some communities become cut off by flooded roads, there is a slight chance that power cuts could occur and other services to some homes and businesses could be lost.

Very warm and humid conditions will lead to thunderstorms developing across parts of Southern England, the South and West Midlands and Wales on both Saturday and Sunday. Thunderstorms will produce torrential rain and hail in places with up to 30 mm falling in an hour, while some places may miss the worst of the heavy rain.

Modified 27th May

Yellow Warning of Thunderstorms for 1st July from Met.Office

Saturday 30 June Published at 10:44

YELLOW WARNING OF THUNDERSTORM for 'South West England', 'Wales'

Updated 30 June at 1030 BST

Valid from 0600 BST on Sun 01 July to 2200 BST on Sun 01 July

While many areas will see little rain, thunderstorms may develop bringing torrential rain, hail and lightning to a few places.

Heavy showers and thunderstorms may affect parts of South West England during Sunday morning, becoming more widespread and also spreading into South Wales by the afternoon. 30 to 40 mm of rain in an hour is possible, though the scattered nature of the showers means it is not certain where these higher totals and any impacts may occur. However where surface water flooding or lightning impacts do occur they are likely to be in only a few places rather than across the whole warning area. The greatest chance of impacts is in the afternoon, with the risk decreasing again on Sunday evening

Some flooding of a few homes and businesses is likely, perhaps leading to some damage to buildings.
There is a good chance driving conditions will at times be affected by spray and standing water, leading to some minor journey delays.
Some short term loss of power and other services due to lightning strikes is possible
