Several villages have been cut off during the flooding
A "major incident" has been declared in flooded areas in Somerset following warnings of further heavy rain.
Many villagers are already cut off by floods and Sedgemoor District Council declared the major incident so it can mobilise extra support.
The area's MP said there was a risk of catastrophic flooding unless action was taken and he asked for government help.
The village of Muchelney has been cut off for almost a month while roads around Langport are expected to flood.
The Environment Agency warned of "significant disruption" caused by a band of rain passing over the area on Friday morning.
Ian Liddell-Grainger, the Conservative MP for Bridgwater, said the county faced a "very difficult weekend".
He has written to Prime Minster David Cameron and Communities Secretary Eric Pickles asking for help.
