Blizzard Alert
2:00pm Friday December 18, 2009
...This is not an official National Weather Service product and should not
be confused for an official watch, warning or advisory...
In New Jersey: Coastal Monmouth, Coastal Ocean
In New York: Nassau, Suffolk, Queens, Kings
...Blizzard Warning remains in effect through 3pm Sunday...
A significant coastal storm will move northeast from the Carolinas to off the
New Jersey and Long Island coasts overnight Saturday into Sunday. A strong
high pressure to the north will result in very cold air and a tight pressure gradient
with the low pressure. As the low pressure rapidly deepens off the coast, winds
in excess of 30 kts will be possible along with heavy snow for at least a 4 hour
period Saturday Night.
Forecast guidance has come into better agreement with the track of this surface
low pressure and strength, although a slight shift would result in stronger or weaker
winds, with a shift to the west or east respectively. Currently, storm snowfall
totals in excess of 12 inches are increasingly possible across the Blizzard Alert area.
The high winds will cause significant blowing and drifting and snow, as well as
near whiteout conditions at times with minimal visibility during heavier snow bands.
There is still some uncertainty with this system, but it is expected to be a high
impact event. Please stay tuned for more information and updates, as well as
your local National Weather Service for official safety information.
...A Blizzard Alert means that blizzard or near blizzard conditions are expected
to occur over the next 12-24 hours or are occurring. Significant amounts of
snow coupled with extremely low visibilities and high winds will make travel
nearly impossible. Travel is not recommended. Please refer to your winter
weather safety procedures...
