Agency gangs have been out checking flood defences and closing tidal flood gates at a number of coastal locations including Truro, Polperro and Plymouth Sutton.
The critical periods will be the early morning tides over the next three days.
If they co-incide with rain, there’s a risk of tide-locking where water is held in rain-swollen rivers and cannot escape into the sea because of the high tides.
