UK Weather Forecast:- Weather experts have issued a tornado warning as well as a warning of strong thunderstorms on Monday. According to the Met Office, winds of up to 70 mph are expected throughout the day, which is likely to “cause power outages”. Winds of 45-55 mph are expected in inland areas overnight Sunday and into Monday, while gusts of 60-70 mph are expected around the coasts and hills. Although these winds are normal for such an autumn storm, trees are still in whole leaf, which could increase the chance of branches or small trees falling.

The forecaster’s STW said: “Convection is likely to organise, possibly developing a few thunderstorms, forming into linear multi-cell convective clusters or even one or two transient supercell formations. Flash flooding from intense rainfall will also be a risk with this activity.”
Rain is expected throughout the day on Monday, with the heaviest rainfall expected in the Midlands. According to the latest update, Britons have been advised to prepare for power cuts by stocking up on torches, batteries, mobile phone power packs, and other essential items.
