Currently the warning level is at yellow. It varies from green to red depending on the severity of the advance warning.
The most recent snow event experienced in the Bailiwick at the end of February and beginning of March was preceded by a red warning but promised blizzards didn’t occur in Guernsey, with occasional snow fall instead. Alderney received a good covering and Sark also experienced some snow.
In March 2013 when the islands came to a standstill for days due to snow was also preceded by a red warning, issued on Sunday 10 March, before blizzards occurred on Monday 11 March, 2013.
