A yellow warning for rain will come in to force for most of Wales from 6pm this evening until Wednesday says Natural Resources Wales.
Spells of heavy rain could lead to surface water flooding and will likely impact roads and driving conditions so please take care if you need to travel and do not drive or walk through flood water.
A spokesperson said: "We don’t provide flood warnings for surface water flooding, so it’s a good idea to check your risk for where you live, work or travel."
