... Winter Storm Warning remains in effect until 9 am CST
Wednesday...

A Winter Storm Warning remains in effect until 9 am CST
Wednesday.

* Timing... snow will continue through the day before ending this
evening. Considerable blowing and drifting of the freshly
fallen snow is likely tonight into very early Wednesday
morning.

* Accumulations... light to occasionally moderate snow will
result in snowfall rates of generally a half inch or less per
hour through this evening. The long duration of the storm will
result in snowfall totals reaching 6 to 10 inches by this
evening.

* Hazards... in addition to the long duration accumulating
snowfall... northwest winds will increase to 15 to 25 mph with
gusts between 30 and 35 mph tonight into early Wednesday morning
resulting in significant blowing and drifting snow. The
potential exists for near white out conditions to develop in
open and rural areas tonight.

* Impacts... travel will continue to be significantly hampered during
the snow storm through tonight. Due to the long duration of
light to moderate snowfall even major roads and highways may
become snow covered. Blowing and drifting snow tonight will
result in near ground blizzard conditions in outlying areas
making travel very 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.






The Flood Warning continues for
the Fox River at Dayton.
* At 845 am Tuesday the stage was 21.4 feet.
* Flood stage is 12.0 feet.
* Moderate flooding is occurring and moderate flooding is forecast.
* Forecast... the river level will be nearly steady for the next few days.
Ice jams can result in rapid rises in water levels with little or no
warning.
