The Met Office has issued a yellow weather warning for the risk of heavy rain on Bank Holiday Monday.
The warning has now been extended to cover all of the Anglia region.
The Met Office Chief Forecaster says: "Rainfall amounts are likely to exceed 15 mm quite widely, while a few places could see more than 30 mm.."
The warning is valid from 6.00am on Monday 25 August 2014 until 11.50pm.
"Heavy rain will spread from the southwest on Bank Holiday Monday. A complex area of low pressure will bring an unpleasant day's weather to much of England and Wales on Monday. The public should be aware that there may be some impacts to holiday traffic and outdoor activities."
It's been the coldest week in the Anglia region since January 2013 with temperatures dipping close to -8°C.
It will be a dry and mostly sunny day, although it will feel a little on the cold side, particularly at first in a north-westerly breeze.
