The Met Office has issued a warning of heavy rain for the West Midlands.
It said that between one and two inches (30 to 50mm) could fall on Monday, much of it in a period of just six hours or fewer.
The region-wide yellow warning highlights a risk of flooding and travel disruption, with pockets of Worcestershire and Warwickshire subject to the more serious amber warning which points to even heavier rainfall.
Some communities in the region may face power cuts and being cut off by flooded roads, the Met Office said.
Difficult driving conditions and public transport delays and cancellations were possible, the Met Office added.
The warnings follow weekend storms that battered the West Midlands and led to flooded streets, evacuations and power cuts.
The National Grid on Monday reported power cuts in more than 25 post code areas including Birmingham, Coventry, Leamington Spa and a location near Market Drayton in Shropshire.
