The Scottish Environment Protection Agency (SEPA) has issued a flood alert across Aberdeenshire and parts of Moray.
Heavy and persistent rain is expected to affect the area with southern parts at greatest risk.
Some localised river flooding to low-lying land and roads is likely, this will be accompanied by difficult driving conditions and ponding of water in known trouble spots.
Isolated property flooding could also occur.
A statement said: “SEPA will continue to monitor the situation and further updates will appear here if the situation changes.”
