Hot weather triggers heatwave warning - but only in the south

The hot weather across some parts of the country has prompted the Met Office to issue the first heatwave warning of the summer.

Temperatures are predicted to soar to as high as 32 °C, with peaks in East Anglia and south east England on Friday and Saturday - although the conditions will be very varied across the country with cloud and rain possible in the north.

Health warning

Head of Health Forecasting at the Met Office, Wayne Elliott, said: "While there is the possibility of daytime temperatures reaching trigger thresholds, it is the night time values which are of real concern."

"High humidity and the lack of any breeze could make matters worse for people with underlying health problems.”

Our tips on keeping cool in a heatwave

Excessive heat can cause dehydration, heat exhaustion and heat stroke. To keep cool and avoid dehydration:

• If possible, avoid going out in the hottest part of the day, between 11am and 3pm, especially if you have existing health problems.
• Drink cold drinks regularly. Avoid drinks which can increase dehydration such as tea, coffee and alcohol.
• When outside, stay in the shade, wear a hat and light loose-fitting clothing. Carry drinks with you. Don't forget the sunscreen.
• Take plenty of cool showers and baths - splashing yourself with cold water on the face and the back of the neck helps.
• Shut and shade windows when it is hotter outside and open them again when it is cooler outside.
• Eat as normal, but try to include more cold foods such as salads and fruit which contain water.

Finally, check on friends, family and neighbours who are more vulnerable to the effects of heat and are less able to look after themselves.
