The Met Office has issued warnings for heavy rainfall and strong wind across large parts of Wales tomorrow and into Tuesday.
It says: "the public should be prepared for the likelihood of significant disruption due to the combined hazards of heavy rainfall and high winds."
A spell of heavy rainfall is expected across South Wales tomorrow, falling onto saturated ground and leading to a risk of some flooding.
There is expected to be 20-40mm of rainfall quite widely, with over 60mm likely on high ground.
Gusts of 70-80mph are likely around exposed coasts.
The warning is in force between 7am on Monday and 9am on Tuesday.
