6:00 AM THURSDAY 2.4.2010 A powerful low pressure system developing across the southwest United States is combining with a significant influx of tropical Pacific moisture enhanced by much above normal sea surface temperatures courtesy of a strong El Nino. This low pressure will tap additional moisture from the Gulf of Mexico and Atlantic Ocean, while moving slowly off the Carolina coast by Sunday morning. Latest computer model indications of 2.0 - 3.0 inches of liquid suggest this will be an historic and extremely heavy wet snowfall across the entire Northeast I-95 corridor from Virginia to southern New England. We urge citizens to heed public safety advisories from local and state authorities as well as the National Weather Service while preparing for this crippling event.

On Sunday, high winds will blow and drift snow, then overnight lows in the teens will freeze solid any snow not removed, potentially paralyzing the region for a significant period of time. A statement from emergency management in Arlington County, VA summarizes the situation:
"A severe winter storm, with near blizzard conditions, is forecast to hit (the region) Friday Feb 5 through Saturday Feb 6. Be prepared to shelter in place for 3 to 5 days. Please stay off the roads. Snow crews will plow primary and secondary roads first for emergency vehicles. It may take 36-48 hours after the snow stops before County plows can get to residential streets. Removal and treatment may take several days."
