The two systems have officially merged and our storm has been born. Currently, the powerful nor'easter is undergoing rapid intensification, a process we call "bombogenesis", which means that a mid-latitude cyclone drops in surface barometric pressure by 24 or more millibars in a 24-hour period.

Over the next 12 to 14 hours, intense bands of snow accompanied with wind gusts over 60 miles per hour. These snow bands will contain some of the
most intense snowfall rates some of us have ever seen! The storm center will slowly move to the north east, eventually coming to a near stall east of Nantucket early Saturday morning.
From 10PM tonight to 10AM tomorrow morning, most locations will receive between 12-18 inches of snow! There have already been scattered reports of thunder snow over the south shore. Thunder embedded in snow bands represents the deep intensification the storm is undergoing. These are the bands that can drop snowfall at rates of 2 to 3 inches per hour.
The wind is also going to become a huge issue. Winds will continue to increase out of the north east, creating blizzard conditions with near white out for visibility. Snow drifts and blowing snow will continue to cover the roads overnight, rendering plows useless and making travel impossible

Coastal flooding is also a concern, especially during tomorrows high tide at 10AM. An area extending from Newburyport all the way south to the Cape and islands, including Boston Harbor, will experience moderate to major flood levels. Loss of property is almost a guarantee.
Snowfall totals still ranging from 24-30 inches for most of the area. Truly an historic storm. Stay safe tonight!
