Flooding and disruption expected as heavy showers and thunderstorms hit Sussex.
The Met Office has issued an amber weather warning for the whole of the county, as well as most of south-east England and parts of London and Essex.
The Weather Service has warned that flooding of homes and businesses is “likely”, with potential deaths from fast-moving and deep floodwaters.
The Met Office has also warned of possible delays and cancellations of train and bus services, as well as power outages.
Up to 100mm is expected in some locations within a few hours, with lightning and hail expected in some areas.
It comes almost a week after a drought was declared in Sussex due to a lack of rainfall.
Dan Suri of the Met Office said that while not all locations will be affected “where thunderstorms occur, there is the potential for very large precipitation totals”.
He said: “If this heavy rain falls on extremely dry ground, the risk of a flash flood is much greater.
“As some southern locations have had no significant rainfall since June, the soils in those areas have been baked by the sun, turning them into hard, almost impenetrable surfaces.
“Any rainfall in these areas cannot seep away but rather washes away soil and other hard surfaces, causing flash flooding in some areas.”
A road on Haywards Heath was flooded yesterday morning after blocked drains couldn’t handle a torrential downpour.
Weather conditions are expected to settle down later this week, with heavy rain and thunderstorms less likely.
Met Office Deputy Chief Daniel Rudman said: “Although the warnings are broad-based, forecasters expect individual thunderstorms to be fairly isolated, with many not encountering gale or heavy rain within the warning.”
The yellow warning comes into effect from 11am and ends at 10pm tonight.
