A yellow weather warning for rain in Buckinghamshire and Berkshire has been extended.
The warning comes into force from 6pm today and remains until midnight tomorrow (November 2).
The Met Office said more wet weather could bring disruption to the region.
"Heavy rain associated with Storm Ciarán is likely to bring disruption to southern parts of England and Wales," they said.

A spokesman said: "Periods of heavy rain, associated with Storm Ciarán, are expected to affect much of southern England and south Wales from Wednesday evening and during Thursday.
"A further 20 to 30 mm is likely quite widely, but 40-60 mm may accumulate in a number of places, especially, but not exclusively, over higher ground. Upland areas of southwest England and south and southwest Wales may see 80 mm of rain in a few locations.
"Given this amount of rainfall, the current saturated conditions, and the potential for fallen leaves to block drains etc, further impacts are likely.
What to expect from the weather:
- Delays or cancellations to train and bus services are possible
- Homes and businesses could be flooded, causing damage to some buildings
- Some communities may be cut off by flooded roads
- Fast flowing or deep floodwater is possible, causing a danger to life
