From the press release:
Markell Declares State of Emergency for Kent and New Castle Counties Effective at 3:00 PM
Motorists In Two Counties Encouraged to Clear Roads as Soon as Possible
Wilmington, DE – Governor Jack Markell declared a State of Emergency for New Castle and Kent counties effective at 3:00 pm today. All non-emergency vehicles are strongly encouraged to remain off Delaware roads in those counties until the State of Emergency is lifted.
To this point, Kent and New Castle have received the brunt of the storm, though western Sussex has also received snow. Conditions are expected to intensify this afternoon with heavy snowfall and strong winds that will make driving exceptionally dangerous. DelDOT crews will be forced to concentrate only on major arteries for plowing, leaving most roads untouched.
Conditions may dictate the declaration be extended to Sussex County later today, though no decisions have been made.
