Several parts of Britain have received heavy rain last night, causing flash floods.
It is expected that damp and windy conditions would continue for some more days as the remnants of Hurricane Bertha are expected to hit the UK on Saturday.
The hurricane has badly affected Eastern England with some areas receiving over 50 millimetres of rainfall in 24 hours.
Several streets in the Lincolnshire town of Louth were left completely flooded and waterlogging was also seen in Maidstone, Kent.
Met Office forecaster Helen Roberts said on Friday said that some towns receive more rainfall in one day than in the whole of an average August.
"(The town of) March in Cambridgeshire had 68.8mm of rainfall in 24 hours, while the average rainfall for that region in August would normally be 53.6mm," she said.
Hurricane Bertha is crossing the Atlantic after hitting the Caribbean with gusts of more than 145kmh and its effects could be felt even today.
Weather experts said that southern parts of the country were exposed to huge risk of 'heavy rainfall, strong coastal winds and large waves'. Areas of northeast Scotland could also receive heavy rainfall on Monday.
A Met Office spokesman said the transition of Bertha from a tropical to an extra-tropical storm was a 'particularly hard one to forecast' but it would most certainly hit several parts of the UK today.
"There is still some uncertainty surrounding this weekend's weather, with the potential for heavy rainfall, strong coastal winds and large waves on Sunday," chief meteorologist Paul Gundersen said.
Environment Agency flood risk manager Craig Woolhouse said: "On Sunday and Monday a combination of high spring tides and strong westerly winds bring a risk of large waves and spray and possible flooding to the southwest coast of England and along the Severn estuary."
