Current watch level: Level 3 - Heatwave Action
Issued at: 08:55 on Wed 15 Jun 2022
There is a 90 % probability of Heat-Health Alert criteria being met between 0000 on Friday and 0000 on Sunday in parts of England.
There is high confidence for temperatures to rise significantly through the second half of this week, becoming hot or very hot in central and southern areas. The peak of the heat is expected on Friday, with daytime maxima likely to reach into the low to mid-30s of Celsius across large parts of central and southern England. Another warm night is expected in similar parts on Friday night before cooler and fresher conditions arrive during Saturday There remains uncertainty in regards to the speed of progression of cooler conditions arriving from the north and west over the weekend. A slower outcome may allow for the very warm or hot conditions to persist across far southern areas on Saturday, before a more definitive return to more seasonable temperatures for all regions of England by Sunday.

Amber — Heatwave action
Triggered when the Met Office confirms threshold temperatures for one of more regions have been reached for one day and the following night, and the forecast for the next day has a greater than 90% confidence level that the day threshold temperature will be met. This stage requires social and healthcare services to target specific actions at high-risk groups.
Advice: Look out for others, especially older people, young children and babies and those with underlying health conditions. Close curtains on rooms that face the sun to keep indoor spaces cooler and remember it may be cooler outdoors than indoors. Drink plenty of fluids and avoid excess alcohol, dress appropriately for the weather and slow down when it is hot.
