Forecasters sounded a health warning today as they predicted a heatwave for the Portsmouth area.
Temperatures are expected to soar into the 30s around the area and across much of the UK.
The Met Office said there was an “80% probability” of heatwave conditions between noon tomorrow and 6am on Thursday in parts of England.
The forecast triggered a ‘Level 2’ alert with the Met Office warning: “Heatwaves can be dangerous, especially for the very young or very old or those with chronic disease.”
A spokesman said: “Temperatures are expected to build on Tuesday and into Wednesday, with the hottest day of the year so far expected on successive days this working week.”
