Storm Dennis: Raft of flood alerts for Cornwall

Published by Emma Carton at 1:44pm 15th February 2020. (Updated at 8:15pm 15th February 2020)

Rivers across Cornwall are on flood watch as Storm Dennis does its worst.

Alerts have been issued from Penzance to Bude as torrential rain hits the Duchy, along with ‘immediate action’ warnings for part of the River Lynher and River Tamar.

Roads have been flooded, including stretches of the A30 at Fraddon and Lockengate.

The Met Office yellow alert for downpours will remain in force until 9pm on Sunday.

It comes just a week after Storm Ciara left the ground well and truly saturated.
