THE Met Office has warned of heavy showers or thunderstorms expected this afternoon (Friday).
In a yellow 'be aware' warning for the south east, including the Isle of Wight, the Met Office said some torrential downpours were possible, accompanied by hail and thunder.
It said showers and thunderstorms would die out this evening.
The chief forecaster said: "An unstable airmass across the south east of England and, with another very warm day expected, coupled with high humidity, some heavy showers or thunderstorms are likely to develop this afternoon within the warning area.
"As is always the case with showers, some places may see no rainfall at all, whilst others receive 20mm or more in an hour.
"Hail and thunder may be an additional hazard. Showers will gradually die out this evening as temperatures decrease."
