Tonight's high tide at Blackrock is set to occur at 11.20pm.
Blackrock Tidy Towns committee have taken to Facebook to ask residents to keep them informed of potential flooding.
"If anybody living on Main Street considers there might be a risk of flooding let us know so that we can alert the Council. It should become clear from around 10.30 whether there's going to be a problem. (We're confined to base ourselves so can't monitor the situation.)"
