The Mendips and North Somerset have been particularly badly affected by heavy rainfall overnight.
According to the Met Office, almost 50mm of rain fell in South Gloucestershire.
A large number of roads were blocked and some households were flooded. In Chew Magna near Bristol, the commute to work was a nightmare as at one point all roads out of the village were blocked.
The above photo was taken in Chew Magna soon after a car was rescued from the bridge.
The following video was filmed by Jo Kidby, who lives in the village, to show the dangerous driving conditions being faced by motorists right across the region.
Avon & Somerset Police have issued the following statement about coping with hazardous driving conditions.
Flooding is affecting much of our region today. If you have photos, we'd love to see them. Email them to email@example.com or post them on our Facebook page. The following picture was taken by one of our viewers, Roger Fry, who's from Hutton in Weston-super-Mare.
At the time of publication, there are 15 flood warnings operating across the whole of the south west. For the latest, log onto the Environment Agency website.
