The rain and snow has triggered flood warnings in Norfolk and Suffolk on the River Waveney and River Tas.
The average March rainfall in East Anglia is around 44 mm but in the 48 hours ending at 9am on Sunday a few places in Norfolk had seen more than that. Lingwood to the east of Norwich had 57 mm while Norwich itself had 48 mm.
