The National Weather Service has posted a Blizzard Warning for the area effective as of 11PM tonight, valid until 8PM on Tuesday.
A mix of rain and snow will overspread the area tonight and transition to all snow from west to east (beginning near the Canal and reaching the far Outer Cape last) in the pre-dawn hours. Expect snow to fall throughout the day on Tuesday and to only gradually taper down to lighter snow and flurries Tuesday evening and night.
Expect snow to fall very heavily at times through at least the first half of the day on Tuesday, with snowfall rates of 1 to 3 inches per hour common at times…with perhaps even a rumble of thunder as some of the heaviest bands of snow rotate northward and onto the Cape during Tuesday morning.
The intense snowfall rates, combined with northeast winds gusting 45 to 65 mph, will create near zero visibility at times and make travel virtually impossible in spots throughout the day. Obviously non-emergency travel is not advised and will be a hindrance to public safety personnel and snow removal operations.
Strong winds combined with a heavy wet snow – particularly on the Lower and Outer Cape where rain could mix in with the snow at times – will result in scattered tree and limb damage, which will lead to localized power disruptions across the area. While winds won’t reach the extreme levels experienced in early March (when gusts reached 80-95 mph), they will howl for extended period of time and also cause extreme blowing and drifting of the snow.
Conditions will only very slowly improve later Tuesday afternoon and evening as the powerful storm slowly wobbles away from the region.
Here is the updated snowfall forecast for the area:
