According to the meteorological service, there will probably be delays in bus and train services, and drivers will be impacted by road flooding.
In addition, a second yellow warning was issued for the Leicester region, effective from Thursday at 2 p.m. until Friday at 3 a.m.
The public has also been cautioned by the Environment Agency not to drive, bike, or walk across floods when there is a lot of rain.
