THE Environment Agency is warning there could be a risk of flooding from rivers and surface water during Friday and Saturday.
Latest forecasts show up to 100mm of rain could fall in the region from 5 a.m. tomorrow.
The exact locations of the bad weather are unknown at the stage, but a weather system of thunder showers and slow moving bands of rain is likely to affect Northern and Eastern parts of Lancashire and Greater Manchester as well as South Cumbria.
This forecast could change closer to the time and this does not mean other areas will not be affected.
“We are urging the public to remain vigilant, check local weather forecasts, and the Environment Agency website for information,” said an EA spokesman.
The Environment Agency has mobilised teams across the North to check and clear river blockages and monitor river levels. It is also working with local partners to ensure surface water flooding is minimised where possible.
Steve Moore, Director of the Environment Agency in the North West, said: “Our latest forecasts show that, over the next 36 hours, some parts of the North West could experience very heavy rainfall.
“We are experiencing a period of very unsettled weather and, where necessary, our teams are out monitoring river levels and ensuring blockages to rivers and drains are removed.”
