Gusts of wind up to 70 miles-per-hour and heavy rain have caused problems across the South West.
Six cars were involved in a pile-up on the A38
Several traffic accidents and localised flooding were caused by the hazardous conditions.
About 30 millimetres of rain fell overnight, and flood watches from the Environment Agency were put in force across much of the region.
In Devon, a tree fell onto a house in Torquay, and the weather was thought to have partly responsible for a six vehicle pile-up on the A38 in Plymouth.
The Devon County Council Control Room said there was localised flooding across Devon, including Compton in Plymouth and on the A377 near North Tawton.
The weather also caused problems for rail passengers on one of the region's main lines after a Virgin voyager train broke down at Dawlish.
Police dealt with a number of road accidents, including one on the M5's north-bound carriageway between junctions 26 and 27, another on the A380 at Kingsteignton.
There was also a six vehicle pile-up on the A38 near the Manadon roundabout in Plymouth which caused long delays, with traffic coming to a standstill from the roundabout back to the Tamar Bridge.
Two people were taken to hospital with slight injuries.
The A38 was closed for an hour and staff from the Highways Agency put sand on the road.
In Cornwall, several roads were covered in debris and had deep surface water, including the Glynn Valley between Bodmin and Liskeard and St Erth in west Cornwall.
Winds stopped high-sided vehicles from using the Tamar Bridge between Devon and Cornwall, and one of the Torpoint ferries could not dock because of rough conditions in the River Tamar.
