TRAINS lines between Fareham and Eastleigh were blocked this morning because of flooding.
South West Trains said services which run through these stations may be diverted via Netley at short notice.
Operators are not sure when services will return to normal as the problem has not yet been fully assessed.
Due to flooding in the Botley area, London services are being diverted via Netley and are unable to call at Botley and Hedge End until further notice.
The train company said customers could travel from Fareham to Eastleigh and travel back in the Portsmouth direction for Hedge End and Botley.
Taxis are being arranged to run between Fareham and Eastleigh as the firm cannot source buses until after 9am.
Heavy rain overnight caused problems on some roads, including the A272 between Winchester and Petersfield. Police warned motorists to drive with care.
Gale force winds and high tides along parts of the coastline could lead to flooding today in the west country.
The west and south coast of Wales and the coasts of Devon, Cornwall and Somerset are likely to experience gusts of up to 60mph, forecasters said.
The Environment Agency said strong westerly winds would cause stormy seas which, combined with some of the highest tides of the year, would lead to high sea levels and spray coming over sea walls.
Low-lying coastal roads, farmland and isolated houses could be vulnerable to flooding, but the agency is also warning of the possibility of more significant problems.
There are currently 25 flood warnings in place, mostly for coastal areas in the South West and Wales, with one also in the North East, and high tides are likely to lead to more warnings being issued.
Gemma Plumb, a forecaster with MeteoGroup, the weather division of the Press Association, said there would be gusts of 50 to 55mph throughout the day along the south west Wales coast and would reach up to 60mph in places, while in Devon and Cornwall they would be between 40 and 55mph.
The Met Office said winds were expected to increase to “gale or severe gale force” on exposed parts of the coast, which could lead to localised disruption to transport.
The Environment Agency said its teams had been out checking flood defences and closing tidal gates ahead of the high tides, and warned people to be careful driving or walking along the coast over the next few days.
People should be particularly careful on exposed areas, where there is a risk of being swept away by waves or being hit by debris thrown up by waves, the agency added
