WINTER STORM SUMMARY FOR
FEBRUARY 13, 2014 TO FEBRUARY 14, 2014 EVENT

Synopsis

An area of low pressure was located near the coast of North Carolina during the early morning hours of February 13th, then tracked northeastward near the Mid Atlantic coast during the 13th into the 14th. The storm combined with plenty of cold air in place and produced a significant snowfall across much of our region. As the low pressure system intensified to our east, gusty northerly winds occurred especially closer to the Atlantic coast. The storm then moved away and allowed the snow to end in the early morning hours of the 14th.

The winds during this storm were mainly from the north and northwest at 10 to 20 mph with some gusts to 30 mph.

Significant Impacts/Aspects

Snowfall rates of 1 to 3 inches per hour during the morning of the 13th greatly impacted the snow removal process, as the plows could not keep up. In addition, significant impacts were felt at the regions airports with many cancellations and delays. This storm resulted in another snow day for many school districts across the region. The bridges over the Delaware River as well as many Interstates in the region had greatly reduced speed limits posted.
