An amber or level 3 "heat health watch warning" has been issued for parts of England this week. The MET Office is urging people to either stay out of the sun or avoid being in the sun when it is at its strongest between 11 a.m. and 3 p.m., Cambridge News reported. The amber, or level three, warning is issued when temperatures are predicted to hit 30 degrees Celsius during the day, and 15 degrees at night, for at least two consecutive days, a Met Office spokeswoman said. There is a 90% possibility of heat wave conditions between 9 a.m. on Monday and 9 a.m. Friday in parts of England, mainly in the south and east, she added. The heat health watch warning is designed to make local services aware that these conditions are being met, and for them to take action. 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. Temperatures will rise as the week progresses with values of up to 34 degrees Celsius predicted locally in the south-east.
