Flood Alert issued on 10 Nov 2018 17:17
River Tamar
Following rain on Friday and Saturday river levels remain high. Bands of heavy showers will continue overnight. The ground is saturated and river levels in smaller watercourses may rise quickly in response to localised heavy rain. Minor flooding of roads and low lying properties adjacent to the river is possible. Blocked drains increase the risk of surface water flooding. Following the strong winds and rain owners of properties at risk of surface water flooding may wish to take steps before the overnight rain to check that nearby drains and gullys are clear of debris such as litter, leaves and branches. We are constantly monitoring river levels and have teams in the field to relay information, clear blockages and operate defences if required. This Alert and Floodline will be updated by 10am Sunday 11th November or earlier if the situation changes.

Flooding is possible during the evening of Friday 9th November. A deep area of low pressure has brought heavy rainfall over the day, with the largest totals over areas of high ground, particularly across the Moors. Further rain is forecast. Strong winds are causing increased autumnal debris and blocked drains, increasing the risk of surface water flooding. Expected levels suggest that there will be some minor flooding of roads and low lying properties near Gunnislake, Morwellham Quay, and Cotehele.
