AN AMBER weather warning for 'extreme heat' has been issued for Hampshire as the county boils in a heatwave.

It is the first time the Met Office has issued an “amber extreme heat warning” as parts of the UK are set to reach a sizzling 33C.

The warning – which is similar to those issued when heavy rain or snow is forecast – covers the whole of Hampshire.

It comes after temperature records were set over the weekend.

Hampshire has experienced temperatures in the mid to high 20's today and the warm weather is set to continue throughout this week.

The weather warning will be in place between 4pm on Monday (July 19) until 11.59pm on Thursday (July 22).

High temperatures are expected both by day and by night, peaking Thursday before temperatures fall on Friday.

Met Office chief operational meteorologist 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 focusses 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.”

Top ways to stay safe in the heat include drinking plenty of fluids and avoiding excess alcohol, keeping out of the sun between 11am to 3pm, walking in the shade, and applying sunscreen and wearing a wide-brimmed hat.

People are also urged to avoid physical exertion in the hottest parts of the day.

What to expect during amber weather warning

  • Adverse health effects are likely to be experienced by those vulnerable to extreme heat
  • The wider population are likely to experience some adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat-related illnesses
  • More people are likely to visit coastal areas, lakes and rivers leading to an increased risk of water safety incidents
  • Some changes in working practices and daily routines likely to be required
  • An increased chance that some heat-sensitive systems and equipment may fail, leading to power cuts and the loss of other services to some homes and businesses
  • Some delays to road, rail and air travel are possible, with potential for welfare issues for those who experience prolonged delays
