Hot weather maps indicate that Greater Manchester will reach 27°C within days, as the UK braces for another heatwave. The Met Office has forecast temperatures climbing to 29°C on Sunday, June 21, with a yellow 'risk to life' warning issued for several regions.
UKHSA Yellow Alert
The UK Health Security Agency (UKHSA) has issued yellow alerts for four English regions: East Midlands, East of England, London, and the southeast. The warning, effective from Wednesday, June 17, until Monday evening, June 22, cautions of a possible risk to life for vulnerable individuals due to temperatures exceeding 32°C in some areas.
Forecast Details
The Met Office predicts heatwave conditions across much of the UK. On Friday, June 19, eastern parts of England may see 32°C, potentially rising to 33°C in the south and southeast by Monday. Greater Manchester's temperature maps show a high of 27°C on Monday, June 22, though localized forecasts suggest it could reach 28°C.
Deputy Chief Forecaster Gregory Wolverson noted: "This week's weather reflects a contrast we often see in summer, with more unsettled conditions passing to the northwest of the UK while heat builds in the south and east. As we move towards the weekend, conditions will become more widely settled and temperatures will rise."
Heatwave Criteria
In the UK, a heatwave is defined as three consecutive days with daily maximum temperatures meeting or exceeding the threshold (25-28°C, depending on location). For Greater Manchester, the threshold is 25°C. Current forecasts show 25°C on Thursday and Friday, dropping to 22°C on Saturday, then rising to 26°C on Sunday, 28°C on Monday, and 26°C on Tuesday, likely meeting the criteria.
Not All Sunshine
Despite the heat, the Met Office warns it may not bring "wall-to-wall sunshine," with potential for heavy rain and thunderstorms. Wolverson added: "While temperatures may be high, we might not see the blue skies experienced in May due to more cloud. There is also a chance of thunderstorms developing, particularly later each day, bringing heavy showers and localized impacts."
