The Met Office has extended its weather warning for extreme heat in an update issued on Saturday morning. The national forecaster has enforced an amber warning covering several areas in the Midlands, London and southern England, as the UK remains in the grip of a heatwave.
The warning, which has been updated on Sunday, will come into force at 12am on Saturday and will remain active untill 9am on Sunday. According to forecaster, hot and humid weather will continue over parts of east and southeast England over the weekend. The rare heat warning is likely to cause adverse health effects including sunburn or heat exhaustion (dehydration, nausea, fatigue) and other heat related illnesses among the wider population.
The forecaster said: “Very hot and humid weather will continue to affect eastern and southeastern England but likely a few degrees cooler than the previous few days. Temperatures will still widely exceed 30 Celsius, peaking around 32 – 33 Celsius in London or East Anglia.
“Temperatures overnight Saturday into Sunday remain unlikely to fall below high teens Celsius for most, with a few places not dropping below 20 Celsius.
“This will again be accompanied by high humidity at first, but fresher conditions will steadily become established from the west during the latter part of the night. Another hot day is expected in the far east of the region on Sunday, but both temperatures and humidity lower than recent days with a much lower likelihood of further impacts.”
The Met Office also warned that there is 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.
