The Met Office is warning about coastal overtopping with waves driven by strong winds.
At high tide tonight at around 10pm and 10am tomorrow morning, strong south-westerly winds could push water and debris onto roads.
This evening, Shore Road in Rushen, Castletown promenade, the northern end of Douglas promenade and Fenella Beach in Peel are likely to be worst affected.
Forecasters at Ronaldsway Airport say they'll monitor poor weather over the weekend and issue more warnings if necessary.
