The flooding is causing a lot of disruption on the region's roads and railway, with rail operator Transpennine Express urging people not to travel unless essential.
The conditions are making driving conditions difficult with some roads impassable.

The weather is also disrupting our railways.
There's a reduced service on Transpennine Express between Carlisle and Glasgow Central, and Carlisle and Edinburgh Waverley, due to poor weather conditions.
