Thunderstorm warnings have been in place for much of the week, but now the Met Office has upgraded one area to amber alert, warning of severe thunderstorms and danger to life. The Met Office warns severe thunderstorms will affect parts of England and Wales on Wednesday evening. Some places will miss these, but where they occur they will be intense.
The amber warning areas are East Midlands, London and South East England, North West England, South West England, Wales, West Midlands and Yorkshire and Humber.
Rainfall totals of 30-40 mm may fall in as little as 20 minutes, with a chance of 60 mm falling in an hour and 70-100 mm falling in 2-3 hours.
Large hail, frequent lightning and gusty winds will be additional hazards. Most thunderstorms will die out during later in the evening though a few may continue in to the night.
The Met Office warns to expect
- There is a chance that fast flowing/deep water could suddenly occur, bringing a danger to life and extensive flooding of homes and businesses
- Damage to buildings/structures from lightning strikes, hail, strong winds may occur
- If flooding occurs, road closures with long delays and cancellations to bus and rail services are possible
- Rapidly changing, dangerous driving conditions from spray, sudden flooding, standing water and/or hail might occur
