Winter Weather Advisory

…WINTER WEATHER ADVISORY IN EFFECT FROM 7 PM THIS EVENING TO

10 AM EST SATURDAY

* WHAT…Mixed precipitation expected. Plan on difficult travel

conditions. Total snow accumulations of up to two inches and

ice accumulations of up to one tenth of an inch are expected.

* WHERE…Portions of central Pennsylvania.

* WHEN…Rain will change to a wintry mix around midnight, then to

snow late tonight. Expect the snow to taper off shortly after

dawn on Saturday.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

The Pennsylvania Department of Transportation and Pennsylvania

Turnpike Commission remind motorists to adjust speeds based on

driving conditions as winter weather impacts Pennsylvania

roadways. Visit www.511pa.com for the latest travel, roadway and

Flood watch

…FLOOD WATCH REMAINS IN EFFECT THROUGH SATURDAY EVENING

The Flood Watch continues for

* A portion of central Pennsylvania, including the following

counties, Cameron, Clearfield, Columbia, Elk, McKean, Montour,

Northern Centre, Northern Clinton, Northern Lycoming,

Northumberland, Potter, Snyder, Southern Centre, Southern

Clinton, Southern Lycoming, Sullivan, Tioga, Union, and Warren.

* Through Saturday evening

* Periods of rain will continue to fall over the area today, some

of which could be heavy this morning. 1 to 3 inches of rain are

expected across the watch area by early this evening. The rain

is expected to change to a wintry mix by late this evening and

eventually snow overnight.

* Area waterways are covered with ice due to our recent arctic

outbreak. Rapidly rising stream and river levels may lead to a

break up of the ice, leading to localized ice jam flooding, as

the ice collects at constrictions. The most susceptible areas

are at bridges or bends in the river, where ice jams could clog

the flow, causing water to back up onto land.

PRECAUTIONARY/PREPAREDNESS ACTIONS…

Keep an eye on area waterways and be alert for sudden rises.

...FLOOD WATCH IN EFFECT FROM THIS EVENING THROUGH SATURDAY
EVENING...

The National Weather Service in State College has issued a

* Flood Watch for a portion of central Pennsylvania, including
  the following areas, Cameron, Clearfield, Columbia, Elk,
  McKean, Montour, Northern Centre, Northern Clinton, Northern
  Lycoming, Northumberland, Potter, Snyder, Southern Centre,
  Southern Clinton, Southern Lycoming, Sullivan, Tioga, Union,
  and Warren.

* From this evening through Saturday evening

* A period of intermittent rain will begin this evening and last
  until it turns into a wintry mix and eventually to snow late
  Friday night and Saturday morning. Rainfall across the watch
  area will be up to an inch and a half even before the transition
  to wintry precipitation begins. This heavy rainfall will occur
  in conjunction with a significant warm up. Eventual totals may
  reach over two inches by Saturday morning, but some of that will
  fall as snow or sleet.

* Area waterways are covered with ice due to our recent arctic
  outbreak. This volume of water running into the streams and
  rivers may lead to large rises on the waterways. The ice may
  melt initially and break up due to the force of the rising water.
  This could also lead to ice jam flooding as the ice collects at
  constrictions, clogging the flow and backing up onto land.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Keep an eye on area waterways and be alert for sudden rises.
