A number of alerts into the orange tier, meaning prepare for a more impactful event—like longer-duration power outages due to wind, or for areas where snow involved, a longer cleanup.
Also, a coastal flooding statement for parts of the NE coast.

2/4 Significant snow likely for central & western parts of the island. GFW and areas just west favoured for heaviest main-system snowfall, with the west coast seeing additional accums from post-storm squalls. #Gander may get briefly dry-slotted, tempering totals somewhat. #nlwx

1/4 Beginning to see convergence among the models on the Monday storm track (especially if we discount the NAM/JMA, which typically aren’t leaned on for #nlwx). Low tracks over or near Fortune Bay while undergoing explosive deepening, then departs via the NE coast.

View from NOAA-20 VIRRS just after noon today showing yesterday's wind maker racing away as a ~960 mb low over the mid Atlantic.
Clear view of a cold and mostly snow-covered island in its wake (though still some bare ground still holding over the SE Avalon).
