A thunderstorm warning is in place across Portsmouth with similar alerts issued over the weekend.
The Met Office has implemented a yellow alert which covers the city, as well as Gosport, Fareham, Havant, Waterlooville, Hayling Island, and much of the south east of England.
“Scattered heavy showers and thunderstorms are expected on Monday,” the forecaster said. “Rainfall amounts will vary from place to place but in some locations 30-50 mm is possible within a couple of hours. Heavy downpours of rain will be the primary hazard, but lightning strikes are also likely along with the potential for hail and gusty winds.”
