A high impact nor’easter dubbed Winter Storm Gail will spread across the Northeast and mid-Atlantic tonight into tomorrow, bringing heavy snow, strong winds and coastal flooding.
The National Weather Service has posted winter storm warnings and winter weather advisories from portions of New England to the southern Appalachians. Among the cities in winter storm warnings are Boston, Hartford, Providence, New York City, Philadelphia, Pittsburgh, Harrisburg, Pennsylvania, and Roanoke, Virginia. Travel should be avoided in these areas.
Per the National Weather Service:
- The driving factors behind this storm include a deep upper-level trough currently swinging across the Mid-South, an area of low pressure developing off the Southeast coast, and a strong arctic high-pressure system located over southern Quebec, Canada.
- These ingredients will result in an expanding area of snow to overspread the Ohio Valley, central Appalachians, and northern Mid-Atlantic today.
- Between the snow in the north and the rain in the south, a wintry mix is forecast to stretch across the southern Appalachians and the interior Mid-Atlantic roughly along the I-95 corridor.
- Freezing rain is the main concern across this region, as upwards of a quarter-inch of ice accretion is possible. This could lead to scattered tree damage and power outages.
- As the precipitation shield advances north throughout the day, heavy snow will overtake areas northwest of I-95 in the Mid-Atlantic. This means major cities, such as Washington D.C. and Philadelphia, will likely see a wintry mix and potentially plain rain for areas just to the southeast.
- The heaviest snowfall amounts from this system are currently forecast across central Pennsylvania, where as much as two feet of snow is possible. This will likely lead to very dangerous, if not impossible, travel conditions and isolated power outages.
- Many locations from eastern West Virginia to far southern Maine are forecast to see a foot of snowfall accumulation.
The GlobalTranz team will continue to track Winter Storm Gail’s impact on shippers and carriers in the affected regions and assist with any weather-related supply chain disruptions.
