The Met Office has issued a severe weather warning as Tropical Storm Henri heads towards Britain.
Brighton and Hove has been included in the list of areas likely to be affected by high winds, with heavy showers adding to the unsettled weather over the coming week.
Wind speeds are expected to top 35mph with gusts of more than 45mph, according to localised predictions.
And an inch of rain is likely to fall in the area over the next 24 hours with up to an inch and a half on Wednesday (16 September).
The Met Office said: “Westerly gales will start to affect the Isles of Scilly and the far south of Cornwall early on Monday morning before moving further north and east across other parts of southwest England and southern coastal counties during the rest of the day.
“Gusts of 45mph to 55mph are likely in some places, perhaps touching 60mph to 65mph across exposed coasts and hills.
“Given that this is one of the first gales of the autumn, the public should be aware of the risk of localised disruption, possibly affecting travel and late holiday activities.
“Gusts will be particularly strong near to heavy showers and may be enough to cause some damage to trees which are still in full leaf.”
