...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.
