Flood Alert issued on 10 Nov 2018 17:18
River Hayle, Perrancoombe Stream, Bolingey Stream, River Cober, Portreath Stream
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.

River Hayle, Perrancoombe Stream, Bolingey Stream, River Cober, Portreath Stream
River levels remain high following the heavy rainfall yesterday. Further showers are forecast throughout Saturday. Following Friday’s rainfall, the ground is saturated and therefore in smaller watercourses river levels can rise quickly in response to localised heavy rain. Minor flooding of roads and low lying properties adjacent to the river is possible. Blocked drains may also increase the risk of surface water flooding. We are constantly monitoring river levels and have operatives in the field to relay information, clear blockages and operate defences if required. This Alert and Floodline will be updated by 8pm or earlier if the situation changes.


Flood Alert issued on 9 Nov 2018 13:22
River Hayle, Perrancoombe Stream, Bolingey Stream, River Cober, Portreath Stream
Flooding is possible during Friday afternoon and evening. A deep area of low pressure will bring a band of heavy rainfall which tracks east during the day. Rainfall will be highest over areas of high ground. Expected river levels suggest that there will be some minor flooding of roads and low lying properties. Strong winds will cause increased autumnal debris, which could block drains and result in localised surface water flooding. 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 if the situation changes.

River Hayle, Perrancoombe Stream, Bolingey Stream, River Cober, Portreath Stream
There is currently a band of heavy rain moving north past the tip of Cornwall. This may move over west Cornwall on the afternoon and into the evening of Thursday 8th November. If the heavy rain does move inland it could cause flooding from surface water and the small streams in west Cornwall. The flood risk is increased by drain and channel blockage from wind-blown leaves and branches. We advise you to check local drains are clear.
