The Met Office issues heat-related warnings that could lead to planned power cuts across parts of the UK. According to reports, the warnings cover multiple regions over consecutive periods starting from Monday and then again from Wednesday. One report says a 47-hour power cuts warning applies to 71 UK areas beginning Monday, linked to extreme heat expected in the coming week. A second report states that a further 48-hour warning applies to 90 areas starting on Wednesday. The timing of the alerts coincides with forecasts for very high temperatures, including conditions where temperatures could reach around 38°C on Wednesday. The warnings are presented as a precaution in response to forecast demand and strain on energy supplies during the hottest period. Across the outlets, the central points are that the Met Office is forecasting extreme heat, that the potential impact includes possible power cuts, and that coverage extends to many local areas with the risk periods spanning roughly two days each.
