Pitsford Hall Weather Station in the county is forecasting more rain for the weekend.
The weather has already caused massive problems for Silverstone with thousands of fans being told to stay away by the organisers of the British Grand Prix after 50 per cent of the public car parks were lost due to the severe weather.
Wellingborough Carnival and the Party in the Park were also called off as a result of downpours in recent days.
Pitsford is forecasting several hours of rain this afternoon, becoming lighter and more patchy this evening and overnight.
Tomorrow (Sunday, July 8) will be unsettled with showers and longer spells of rain continuing and becoming heavier as the day wears on.
The rain should die down for a while during the evening, but further heavy showers are expected overnight into Monday.
Looking ahead into next week, showers and longer spells of rain are likely through Monday, Tuesday and Wednesday.
