The Environment Agency has upgraded a flood alert notice on the River Hipper to a flood warning.
The warning covers the central Chesterfield part of the river including Park Road on Ravenside Retail Park.
A statement on the Environment Agency’s website said: “Persistent rain combined with heavier bursts has led to rising river levels. This is expected to continue to rise through this afternoon and into this evening.”
Derbyshire police has also been called to the Horns Bridge roundabout in Chesterfield.
An officer said the area was flooding quite badly and cars were getting stuck. The roundabout is down from three lanes to just one.
Derbyshire County Council has said it is monitoring the situation and drivers are being warned to expect delays.
Matlock Road, Chesterfield, where the old White Hart pub used to be, has been closed off due to flooding.
The county council is looking to pump out the water from the area.
Meanwhile on the River Rother from Chesterfield to Staveley, including the Drone and Whitting, a flood alert - the first stage in the Environment Agency’s warning system - is in place.
Heavy rainfall with torrential downpours, strong winds and the risk of gales, are also expected over the Peak District, later today.
