Warning Description: Winter Storm Warning
Warning Date: 10:26 PM EST on February 8, 2010/
WarningSum:...Winter Storm Warning Remains In Effect Until Noon Cst /1 Pm
Est/ Wednesday...
Warning Message:A Winter Storm Warning is in effect.
* Timing...snow will continue across the region overnight and
increase in intensity somewhat. The snow will continue through
Tuesday night. Blowing and drifting snow with near blizzard
conditions in open areas can be expected Tuesday night into
early Wednesday.
* Accumulations...snowfall rates will generally be light to
moderate...however the very long period that the snow will be
falling over will allow storm total snowfalls of 8 to 10 inches
to accumulate by late Tuesday night.
* Hazards...in addition to the long duration accumulating
snowfall...northwest winds will increase to 15 to 25 mph with
gusts to 35 mph late Tuesday and will continue through
Wednesday morning resulting in significant blowing and
drifting snow. The potential exists for ground blizzard and
near white out conditions to develop in rural areas late
Tuesday night into Wednesday morning.
* Impacts...travel is likely to be significantly hampered during
the snow storm overnight through Wednesday morning. Due to the
long duration of light to moderate snowfall even major roads and
highways may become snow covered. Blowing and drifting snow
Tuesday night into early Wednesday will result in near ground
blizzard conditions in outlying areas making travel extremely
dangerous.
Precautionary/preparedness actions...
A Winter Storm Warning means significant amounts of snow...
sleet...ice...or strong winds are expected or occurring. This
will make travel very hazardous or impossible. If you must
travel...keep an extra flashlight...food...and water in your
vehicle in case of an emergency.
