THE mercury is set to soar over the next two days.

Temperatures heading into the high 20s are forecast across BCP on Monday.

A yellow heat health alert has been issued for much of the country, including the south west, and will be in place from 9am Sunday, August 11, until 9am on Tuesday, August 13.

Dan Holley, Met Office deputy chief meteorologist, said: “We expect to see a relatively brief hotter and more humid spell of weather for Sunday and Monday, before these hotter conditions recede on Tuesday, allowing more unsettled conditions to return.

“This change to hotter conditions is caused, in part, by the effects of Tropical Storm Debby in North America. Debby is helping to strengthen the jet stream, causing it to meander over the Atlantic. This will allow hot air over France to move into the UK later this weekend, and early next week.”
