Heavy rain and strong winds are forecast for Bournemouth, Christchurch, Poole and east Dorset today.
Winds are expected to reach 63mph at around midday, with rain continuing into the afternoon.
Some attractions will offer a limited service today, including Moors Valley which is planning to stay closed until Tuesday.
The Met Office says: “Strong winds are likely to cause some disruption on Sunday, whilst spells of heavy rain may lead to some local flooding during Sunday and Monday.
“A period of heavy rain is likely to affect central and southern England and much of Wales during Sunday morning followed by some heavy, thundery showers. Quite widely, 10-20 mm will fall, with locally nearer 30-50 mm over high ground, particularly over exposed south or southeast-facing upslopes.
“It’s then possible that a further spell of heavy rain may develop and affect parts of England and Wales on Sunday evening, clearing early Monday and should this be the case a few places may see as much as 80 mm of rainfall in total.
“Given recent heavy rain, this extra rainfall could lead to some local surface water and river flooding.”
