Hailstorms and lightning are also likely. They added: “A band of very squally showers is expected to push quickly east across the warning area, reaching the Isles of Scilly and Cornwall by 5am, then continuing quickly east through Tuesday morning.

"Showers will likely be accompanied by thunder and lightning. Gusts of winds to 40-50 mph are also likely, as is hail. The last of the showers should clear into the North Sea late Tuesday morning.” The Met Office said there would be a chance of damage happening to a few buildings due to strong gusty winds and possible lightning strikes.

They added that driving conditions will be affected by spray, standing water or hail, delays on public transport routes are possible and there could be power cuts for short periods of time.

The Met Office forecasts rain over Portsmouth until 1pm, with an average temperature of roughly 13C.
