Flooding possible. Be prepared.

Flood alert

There is the small possibility of flooding of the most vulnerable low-lying properties as well as roads and low lying land. Flooding is possible two hours each side of the high tide tonight at 10 PM. Areas most at risk include the coastline between Portishead Point and Avonmouth.
The tidal forecast peak level at Avonmouth is 7.93 mAODN at 10 PM tonight, Friday 20/09/2024, with north-easterly force 5 winds. (mAODN is height above average sea level.)

Tidal conditions are expected to improve after this high tide and further flooding is not expected. We are closely monitoring the situation and closing flood gates. Be careful along beaches, promenades, coastal footpaths and roads as large waves and sea spray could be dangerous. We will remove this message by 11:00 AM on Saturday.
