SUMMER may be officially here but if you were planning on packing away your raincoat this weekend you might want to think again.

The Met Office has issued a yellow ‘be aware’ warning for Bournemouth, Poole and Dorset on Saturday, which is valid from 12.15am until 11.45pm.

The warning says: “Thundery downpours are expected to affect parts of England, Wales and southern counties of Scotland during Saturday.

“The public should be aware of the potential for localised flooding due to the intensity of these storms, although at this stage the location of the heaviest rainfall is uncertain.”

A spokesperson for the Met Office said: “Warm, humid air is likely to be pulled northwards from France late on Friday and during Saturday. Within this airmass, there is an increasing likelihood that heavy, thundery showers will break out.

“It is likely that many places within the current broad warning area will miss the worst of the storms; over the next few days it may be possible to focus on the areas most at risk."
