Amber 'extreme heat' warning extended as government holds heatwave crisis talks
There is a concern the hot weather could lead to a national emergency
An amber weather warning for 'extreme heat' that covers part of Cornwall has been extended to cover all of Sunday AND Monday.
The Met Office says the exceptionally high temperatures could cause health effects, especially in the most vulnerable, which could lead to potential serious illness or even a danger to life.
Areas in north and east Cornwall will be affected by the warning, including Camelford, Liskeard, Callington, Launceston and Saltash.
Senior government officials have held a Cobra meeting to discuss plans in case the UK sees its first ever heatwave emergency.
There is a concern the hot weather could lead to a national emergency.
At the moment there is already a Level 3 'heat health alert' in force across the whole of the Duchy which lasts the whole week.
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
A Met Office spokesperson said: "Temperatures will rise again later this week and over the coming weekend, likely peaking on Sunday and Monday, but may last into Tuesday in places.
"Some exceptionally high temperatures are possible and cumulative effects of warm nights and hot days are expected to bring widespread impacts to people and infrastructure."
