A red weather warning has been issued by the MET office as a storm front moves in from the West.
A band of rain and gales are expected to sweep across the area and the rest of the country.
A statement from the MET Office said: “Around 10-20mm of rain is possible fairly widely with 20-30mm possible in parts of Wales and South West England.
“The strongest winds are expected during the afternoon and evening across Wales and northern England. Gusts of 70-80 mph and perhaps as high as 90 mph are possible around exposed western areas, with 50-60 mph generally across inland and southern areas.
“These potentially damaging winds could bring down trees and cause disruption to travel and power networks.
“In addition, large waves could cause problems around coastal areas.
“Thursday will see generally less windy weather, with some scattered squally showers which could be wintry at times.”
Martin Young, Met Office Chief Meteorologist, said: “With more rain on the way and very strong winds, it’s likely we will see more impacts over the next few days.
“The winds through Wednesday could see trees brought down, which could cause disruption to transport and power networks. Gusts will be strongest in western and northern parts of England and Wales during the afternoon and evening.
“Further rain both on Wednesday and Friday could also lead to further flooding.”
Lytham Hall’s woodland walk was closed on Wednesday due to high winds.
