The Northeastern U.S. is bracing for what the National Weather Service calls "a storm of historic proportions:"
Snow accumulations of around 500-750 mm with locally higher amounts [are forecast]. Snowfall rates of 50-100 mm an hour at times.
A blizzard warning is issued when sustained winds or frequent gusts over 56 km/h are expected with considerable falling and/or blowing and drifting snow. Visibilities will become poor with whiteout conditions at times. those venturing outdoors may become lost or disoriented...so persons in the warning area are advised to stay indoors.
All unnecessary travel is discouraged beginning Monday afternoon to allow people already on the road to safely reach their destination before the heavy snow begins and to allow snow removal equipment to begin to clear roads.
The worst snowfall on record in the Northeast dumped 683 mm of snow on Central Park over 11-12 February 2006. This one could be bigger.
Hang in there, New York and Boston. And just remember the immortal words of Michael Bilandic: "Snow melts."
Update: The governors of New York, Connecticut, and New Jersey have ordered precautionary measures including closing state offices and ordering all cars off the roads tonight. All flights at Boston Logan are cancelled starting 7pm EST tonight; New York airports are also shut Tuesday. The New England Patriots have skipped town early to get to the Superbowl on time. And residents of Maine are...well, they're not doing anything special, because it's just snow.
