Residents in parts of Crayford, Sidcup and Dartford have been sent automated telephone messages over the past hour warning of potentially imminent flooding.
The River Cray is at risk of bursting its banks.
A government website also lists the danger.
“This Flood Warning has been issued as the heavy rain currently being experienced may lead to property flooding overnight.
Flooding to property is forecast from 11:45pm, Wednesday 20 October. Flooding is likely in multiple areas along rivers in the area, properties are particularly at risk in the Crayford and Dartford areas including around Greyhound Way and Crayford Way.”
“Please take action to protect yourself and your property if you believe you are at risk, try to avoid contact with flood water in the areas mentioned. We will be closely monitoring the situation and will have staff working to keep rivers in the area clear.”
There is also potential flooding in Thamesmead.
Plenty of weather to watch over the next few days.
We're making plans to close the #ThamesBarrier tomorrow, which if it goes ahead would be our first of this flood season and our 200th flood defence closure since it became operational in 1982.
