 | Amber warning for South West England |
| Extreme heat | |
| Between 00:00 (UTC+1) on Mon 18 Jul 2022 and 23:59 (UTC+1) on Tue 19 Jul 2022 |
What to expect
- Population-wide adverse health effects are likely to be experienced, not limited to those most vulnerable to extreme heat, leading to potential serious illness or danger to life. Government advice is that 999 services should be used in emergencies only; seek advice from 111 if you need non-emergency health advice.
- Substantial changes in working practices and daily routines likely to be required
- Significantly more people are likely to visit coastal areas, lakes and rivers leading to increased risk of water safety incidents
- Delays on roads and road closures are possible, along with delays and cancellations to rail and air travel, with potential for significant welfare issues for those who experience even moderate delays
Further details
Exceptional, perhaps record-breaking, temperatures are likely on Monday, then again on Tuesday. Nights are also likely to be exceptionally warm for the UK, especially in urban areas. This is likely to lead to widespread impacts on people and infrastructure. Temperatures are expected to drop away from Wednesday onwards.
