The Met Office says people should be aware of the risk of difficult driving conditions due to localised surface water flooding and possible debris from trees.

The Met Office warning states: "A spell of heavy rain and some very strong winds are expected to sweep across southern and southeastern parts of England during Saturday night and Sunday morning.

"Gusts of 45-55 mph are likely inland and 60-65 mph near the coast, but we now expect the strongest winds to affect coastal counties from the Isle of Wight eastwards, where 70-80 mph gusts are possible."

"A vigorous area of low pressure, now named Storm Angus, will move northeast across southern and southeast England on Sunday.

"This will be accompanied by a period of heavy rain, starting in the west of the area during Saturday evening, and very strong winds. 20-30 mm and locally 40 mm of rain is expected within a 6-9 hour period.

Conditions are expected to improve from the west during the late morning and early afternoon."

The Met Office says the warning area has been extended further west and north, but there remains some uncertainty about the exact track of the weather system and therefore the northward extent of any impacts.
