The Met Office has issued a yellow weather warning for parts of west Norfolk this week.
An area including King's Lynn, Downham Market, Wells-next-the-Sea and Hunstanton will be affected by the bad weather on Tuesday, the forecaster says.
Heavy and persistent rain is expected, which could cause homes and businesses to flood.
Travel could be disrupted due to spray on the roads causing slow moving traffic. Roads could also be flooded by the heavy downpour.
The wet weather will subside by Wednesday although the air will still feel cool. Warmer weather can be expected later in the week from Thursday onwards, bringing sunshine and highs of 19-21c.
Tuesday's weather warning comes after Saturday saw heavy rain and wind batter north and east Norfolk, signalling autumn has well and truly arrived.
