THE Environment Agency is warning that there could be a risk of flooding from rivers and surface water during Friday and Saturday.
Latest forecasts show that up to 100mm of rain could fall in the region starting at 5am tomorrow morning.
The exact locations of the bad weather are unknown at the stage, however 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 that other areas will not be affected.
The Environment Agency has mobilised teams across the North to check and clear any river blockages and closely monitor river levels.
They are also working with local partners to ensure that surface water flooding is minimised where possible.
The public are encouraged to remain vigilant and those concerned about flooding can call Floodline 0845 988 1188.
