Met office tells britons to stay indoors until friday as amber weat...

Britain is baking in some of the highest temperatures for more than 100 years this week as forecasters warn temperatures could soar to a sweltering 35C.  Today the mercury rose to 33.3C in

Santon Downham in Suffolk, making it the hottest day of the year, according to the Met Office. The heatwave is to continue across much of England this week, with many areas expected to bask

in the high 20s, with others reaching 32C to 34C. The Met Office level-3 heatwave action warning urges people to keep away from the sun between 11am and 3pm as temperatures are predicted to

hit 30C (86F) during the day, and 15C (59F) at night.  It reads: "There is a 90 percent probability of heatwave conditions between 0900 on Monday and 0900 on Friday in parts of England.

"Stay out of the sun. Keep your home as cool as possible – shading windows and shutting them during the day may help. RELATED ARTICLES "Open them when it is cooler at night. Keep

drinking fluids. If there's anybody you know, for example an older person living on their own, who might be at special risk, make sure they know what to do."  The amber, or level

three, warning is issued when temperatures are predicted to hit 30 degrees during the day, and 15 degrees at night, for at least two consecutive days.  An amber heatwave action alert is

triggered when the Met Office confirms threshold temperatures for one of more regions have been reached for one day and the following night, and the forecast for the next day has a greater

than 90 percent confidence level that the day threshold temperature will be met. This stage requires social and healthcare services to target specific actions at high-risk groups. The UK is

being battered by extremely hot temperatures again as a new heatwave from Africa will reach the country pushing temperatures to up to 33C. Forecasters told people to prepare for "very 

warm and muggy overnight conditions".  Uk weather forecaster: Britons have been urged to 'stay out of the sun' (Image: GETTY/MET OFFICE) UK weather forecast: Met Office have

last month. If thermometers nudge past 33C (91.4F) it will be the hottest day since last summer when London’s Heathrow hit 34.5C (94.1F). If we beat the 34.5C (94.1F) on Wednesday it will be

the hottest day since July 2015 when temperatures at Heathrow hit 36.7C (98.06F). Uk weather forecast: Met Office increase the weather warning to Level 3 (Image: Met Office) With highs of

35C (95F) forecast by the end of next week Britain is facing some of the highest temperatures for a century. The record for July 25 is 33.9C (93.02F) set in Regent’s Park, London, in 1900;

for July 26 it is 33.3C (91.94F) recorded in Southampton, in 1885 and for the 27th it is 34.4C (93.92F) recorded in Margate, Kent, in 1933. The all-time UK record of 38.5C (101.3F) set in

Faversham, Kent, in August 2003, could also topple before the end of summer, according to some long-range experts. The hottest July day on record is 36.7C (98F), which was reached at

Heathrow on July 1 2015. UK weather forecast: Britain is baking in a summer heatwave (Image: MET OFFICE ) Porthmadog in North Wales holds the record for the hottest day of the year so far,

with temperatures reaching 33C (91.4F) on June 28. Nearly all parts of the UK are seeing above average temperatures, but it will be hot or very hot towards the east or south east. During the

current heatwave, UK temperatures have been approximately 10C higher than average for this time of year. Instead of 23C (73.4F) which could usually be expected in London in July,

temperatures could tip 34C (93.2F). Scotland, which averages 17C (62.6), could enjoy highs of up to 25C (77F), while Wales could jump to 26C (78.8F) or 27C (80.6F) instead of 19.2C (66.5F).

Those in Northern Ireland may be basking in 24C (75.2F) rather than the July average of 18.5C (65.3F). "We advise the public to take care in the sun, especially when temperatures are

potentially reaching 30 degrees or more throughout this week, either stay out of the sun or be sensible and don't go out in the strongest sunshine hours (11am to 3pm)," the Met

Office spokeswoman said. Members of the public were also urged to take the usual precautions in the sun, including covering up, wearing sun screen and drinking plenty of water. Dr Thomas

Waite, consultant in health protection at Public Health England, said: "Temperatures are likely be high in parts of England this week, which may leave older people, young children and

those with long-term conditions, including heart and lung diseases, struggling to adapt to the heat." As temperatures soar, the Met Office said the first half of the summer in the UK

has been the driest since 1961. The Met Office said several places have had 54 consecutive dry days since May 30, including a few which have had less than 1mm of rain in the period - the

longest spell since 1969, when 70 days passed with no significant rainfall. A Met Office spokesman said: "It's the driest first half of the summer since 1961. "For the UK as a

whole, we've only seen about 20% of the rainfall we'd normally expect throughout the whole summer. Parts of southern England have seen only 6 percent.” The TUC is urging offices

to relax dress codes during the heatwave to help workers cope. The union has suggested office staff be allowed to work flexible hours to avoid travelling in the rush hour and bosses should

also provide fans and cold drinks and let workers wear lightweight clothes. Staff are not expected to work when the temperature drops below 16C - or 13C if they are do physically demanding

work, but there are no restrictions for when the workplace becomes too hot. General secretary Frances O'Grady said: "It's no fun working in a baking office or factory and

employers should do all they can to take the temperature down. "The most simple way for staff to keep cool inside when it's scorching outside is being able to work in more casual

clothing. While shorts and vest tops may not be appropriate for all, nobody should be made to wilt in the heat for the sake of keeping up appearances. "Bosses who provide a cool and

comfortable work environment are going to get more out of their staff. "Workers who are unable to dress down in more appropriate summer clothing, or who work in offices without

air-conditioning, fans or a plentiful supply of cool drinking water, are going to feel lethargic, and lack inspiration and creativity."
