A Met Office warning for snow and icy conditions in Northumberland has been extended until Wednesday.
An Arctic airmass hangs over the region and is sufficiently cold for snow showers to accumulate at low levels.
The latest yellow (be aware) alert, issued at lunchtime today, predicts heavy snow showers for most of the county, but particularly in the east on Wednesday, following earlier warnings of snow for the rest of the weekend, Monday and Tuesday.
The agency has said: “The Arctic airmass already over UK will continue to bring frequent and heavy snow showers to eastern parts of the UK during Wednesday, giving icy patches in places. A band of more-organised sleet and snow is expected to reach northwestern areas later in the day. Accumulations of snow are possible in places, even to low levels. The public should be aware of the potential for disruption to travel.
“Later on Wednesday, an Atlantic weather system is expected to move towards north-western UK, and this is likely to bring a more-organised period of snow to many north-western areas, especially over high ground. However, there are some uncertainties with regard to the detail of this weather system, including its timings, and thus this alert is likely to be updated and refined on Sunday.”
