An amber weather warning has been issued by the Met Office - but only for Ramsey.
The warning - for Coastal overtopping and inner harbour flooding has been upgraded from yellow for the town.
It's expected the high tide tonight will cause flooding in the Quay, but also Christian Street and Parliament Street.
A yellow warning remains in place for some areas of Douglas - including Lake Road and Tesco car park.
