The Met Office is warning of heavy rain causing potential flooding over the Christmas period.
It says: "Outbreaks of rain will gradually spread north across Wales and northern England through the course of Christmas Day, reaching southern parts of Scotland during the early hours of Boxing Day. The rain will be heavy at times, particularly over high ground and will persist through much of Boxing Day. Be aware of the potential for flooding and some disruption to transport.
"There is still uncertainty over where the heaviest rainfall will be in the warning area, but around 60 to 80 mm is likely to fall quite widely, with a chance of up to 150 mm locally over high ground. Despite uncertainties in frontal positioning and therefore rainfall amounts, there is increasing evidence to suggest rainfall accumulations will be high enough to cause some medium levels of disruption. Given sensitivities with saturated ground over Cumbria, the likelihood of medium impacts is higher here and as a result an amber alert has been issued for parts of Cumbria."
The alert, from around 3pm tomorrow, applies mainly to the western half of Northumberland, although Storm Eva is proving unpredictable.
