Met Office issues first-ever extreme heat warning across South
There have been record temperatures recorded in England and Wales
Last updated 20th Jul 2021
The Met Office has issued its first-ever extreme heat warning for South and South-West England and South Wales as the UK experiences high temperatures.
The warning – which is similar to those issued when heavy rain or snow is forecast – covers a large part of Wales, all of south-west England and parts of southern and central England, and will remain in force until the end of Thursday.
The alert is in force across all of Dorset and the Isle of Wight and much of Hampshire, with the exception of some eastern areas such as Havant and Petersfield.
It is the first time the warning has been issued since the Met Office said last month that it would launch weather warnings for extreme heat after a record-breaking number of heatwave deaths were recorded in England last summer.
Temperatures are expected to reach 33C in some western areas later this week, with high 20s and low 30s expected elsewhere.
Chief operational meteorologist at the Met Office, Steven Ramsdale, said:
“The high temperatures are going to continue through a large part of this week. Many areas will continue to reach heatwave thresholds but the amber extreme heat warning focuses on western areas where the most unusually high temperatures are likely to persist.
“There’s a continuing risk of isolated thundery downpours late in the afternoons but most areas will stay dry until later in the week. Temperatures should begin to fall for most areas heading into the weekend, with some more unsettled conditions looking to develop.”
