According to the United Kingdom Government’s “Check for Flooding” service, which is currently being beta tested:
Flood alert for Upper River Tamar
Flooding is possible – be prepared
This Flood Alert remains in force. Flooding is possible this afternoon and overnight into Thursday 30th December. Last night’s rain has caused river levels to rise and we expect these to remain high throughout the rest of today and into tomorrow morning. This may result in flooding to low lying land and roads close to rivers this afternoon and overnight into Thursday morning 30th December. However, flooding to properties is not currently expected. Take care near the areas of concern and monitor your local weather conditions. We are monitoring river levels and have staff in the area checking for and clearing blockages. This message will be updated on Thursday morning or earlier if the situation changes.
Flood alert area: Bude, Helebridge, Bridgerule, Canworthy Water, Launceston and Yeolmbridge
