The Met Office has issued a yellow weather warning for Berkshire as heavy rain is expected across the county.
Residents are being warned of the potential of disruption, particularly to transport during the rainfall.
The yellow rain warning will be in place from 2am on Thursday, February 8, until Friday morning at 6am.
The Met Office said: "A couple of bands of rain, heavy in places, will push northwards across southern England and south Wales during Thursday and early on Friday.
"Whilst a drier interlude is likely for a time during the middle part of Thursday, many places in the warning area will see 15-25 mm of rain accumulate during this period.
"However, some higher ground areas of southern England and south Wales could see as much as 35-45 mm of rain."
It is advised people check whether their properties are at risk of flooding and prepare an action plan.
The Met Office added: "Give yourself the best chance of avoiding delays by checking road conditions if driving, or bus and train timetables, amending your travel plans if necessary."
