For those getting hung up on BBC weather charts and forecasts, don't bother with them. Apps are rubbish too.
Keep up to date on the Met Office page and app to give you alerts when warnings are updated and changed.
lastly don't forget to watch Carol in the morning, firstly because she is awesome and secondly she's live so if there are any changes you'll know about them.
Remember too, the BEST tool is the radar. EVERYTHING that falls will be snow!
Enjoy. Stay safe, it's going to be epic.
