Headline

Thunderstorms are likely, these potentially severe, bringing a risk of flooding and disruption to travel.

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 slight chance that power cuts could occur and other services to some homes and businesses could be lost
Further details

Reason for update

Warning updated to reflect increased likelihood of thunderstorms.

Further details

Thunderstorms are expected to spread north from France on Monday night before clearing away into the North Sea during Tuesday morning. Whilst some locations will miss these storms, where they do occur 20-30 mm of rain could fall in one hour, with a few spots perhaps seeing as much as 40-60 mm in an hour or two. This is very unusual for the UK. Hail, lightning and gusty winds are also likely in some places.

Further details

Reason for update

The category has been changed from thunderstorm to heavy rainfall, with reduced impacts, and updates to the warning area and headline rainfall accumulations.

Further details

Heavy rain is expected to affect southern Scotland from early Monday, then move northwards across central and eastern Scotland through Monday. In many locations 20-40mm of rain may fall in a 12-18 hour period, with peaks in excess of 80mm possible over high ground. Although some isolated thunderstorm activity is expected, the heavy rainfall aspect has now been deemed to be of greater significance.

Further heavy thundery rain may then arrive into parts of southern and southeastern England and East Anglia during the evening. In areas affected by the thundery rain, 15 to 30 mm may fall widely and 30 to 40 mm of rain may fall over parts of northern England. In areas affected by isolated heavy thunderstorms, 30 to 40 mm of rain may fall in an hour in a few places.
