The Met Office has issued a severe weather warning with heavy rain and high winds heading for Brighton and Hove today (Monday 24 August).
The official weather forecaster said that more than 2in of rain could fall in a few hours in some places.
The chief forecaster said yesterday: “A low pressure system is expected to run into the UK from the south on Monday morning, bringing areas of heavy rain particularly across some southern areas of England.
“There remains some uncertainty over the locations of the heaviest rain but with the potential for 20mm to fall quite widely and with 40mm to 60mm possible in some places, much of this falling in a few hours.
“Latest indications are that the most intense rainfall may be expected across parts of south east England and the southern portion of East Anglia during the afternoon, as brightening skies supply extra energy, leading to development of slow-moving thundery showers.”
The Met Office warned of “persistent and heavy rainfall in places” although “some places will miss the heaviest rain”.
It added: “The public should be aware of the risk of flooding, including disruption to travel.
“In addition to this there is the potential for strong winds, particularly around exposed coastal areas.”
Wind speeds are expected to reach almost 30 knots (35mph) with gusts of almost 40 knots (46mph) over the coming couple of days.
Another inch of rain is forecast to fall on tomorrow (Tuesday 25 August) and Wednesday.
