An amber weather warning for heavy rain will be in place for a most of tomorrow.
Adverse conditions are expected to affect the Island from 7am until 2pm.
The Ronaldsway Met Office says there will be a further 15-20mm of rain at low levels with 30-40mm over high ground.
This will mean standing water in prone locations as well as a moderate risk of localised flooding, especially in recently affected areas.
As well as rain, minor coastal overtopping is expected around high tide at 1:15pm, affecting most of the Island's promenades.
