UK weather: thunderstorm warnings in north and 34C predicted in south-east
Alerts about potential disturbances from thunderstorms have been given for areas in the north of the UK, while southern England could experience what might be the warmest day of the year up to now.
It was predicted that temperatures would reach 34C or higher in the south-east on Monday. The hottest day of the year in the UK so far was on 19 July when a temperature of 31.9C was recorded at St James's Park in central London.
A representative from the UK Health Security Agency has stated that a yellow heat health alert will be in effect until 9am on Tuesday in various regions of England, including London, the south-west, south-east, east of England, East Midlands, and West Midlands.
A disturbance in the jet stream, triggered by Storm Debby in the US, is shifting warm air towards the north and is likely to result in thunderstorms. The Met Office has issued a yellow warning for thunderstorms on Monday for northern England, Scotland and Northern Ireland.
It cautions that unexpected floods could make driving challenging and result in road closures. Some towns may also be temporarily isolated due to flooded roads.
The Met Office also mentioned that there is a small possibility of power outages affecting homes and businesses due to strong winds reaching gale force, especially in northern Scotland.
The advisory mentioned that even though not all locations in the warning area may experience them, there is a high chance of organized thunderstorms bringing frequent lightning, heavy rain, hail, and brief periods of strong winds. Some very heavy rainfall is expected, with 20-40mm in some areas and a possibility of 40-60mm of rain falling in one to two hours in isolated spots, along with hail up to 2cm in size.
It said: "Get ready to keep your belongings and individuals safe from harm. Prior to the arrival of strong winds, make sure that things that can be moved or structures that are temporary are securely fastened. These items may include: trash cans, outdoor furniture, trampolines, tents, gazebos, sheds, and fences."
The weather predictions say that the thunderstorms will move away towards the northeast by Monday afternoon. The high temperatures in the southern areas will likely decrease to more typical levels for this time of year by the middle of the week.
The hot weather will cause more nettle and mugwort pollen in the air and strong UV rays. The Met Office suggests wearing protective clothing and using sunscreen around noon.
