Flood alerts have been issued across the South West as heavy and prolonged rain brings a miserable end to the week.
Persistent rain is expected to fall on Thursday and Friday in Devon and Cornwall.
Up to 60mm of rain (2.4 inches) is expected across many parts of the region, equal to more than half of the average monthly rainfall in March.
An entire month's worth of rain (100mm) could fall on exposed coasts and upland parts by the end of Friday.
Some 15 flood alerts are in place across the South West including St Austell and Par rivers in Cornwall.
The Exeter-based Met Office has upgraded its severe weather warning to amber across vast swatches of Devon and Cornwall, telling people to 'be prepared' for heavy rain.
It warned heavy and persistent rain would continue to fall on Thursday and through most of Friday.
The Environment Agency warned the heavy rain could lead to flooding in the South West.
Agency spokesman Ben Johnstone said: "We strongly urge people to sign up to flood warnings on the Environment Agency website, keep a close eye on local weather forecasts and be prepared for possible flooding. We also ask that people stay safe and not try to wade or drive through any deep water."
Teams are out monitoring river levels and could upgrade some of the alerts to flood warnings.
