...WIND ADVISORY IN EFFECT FROM 2 AM TO 2 PM EDT MONDAY...

The National Weather Service in State College has issued a Wind
Advisory, which is in effect from 2 AM to 2 PM EDT Monday. 

* TIMING...Late Sunday night through Monday morning. 

* WINDS...Northwest 20to 35 MPH with gusts as high as 45 to 50 MPH
  at times.

* IMPACTS...Strong winds will bring down tree limbs and will lead
  to smaller loose objects being blown about. The combination of
  heavy rain softening the ground and strong wings may also cause
  trees to topple, which could fall on power lines causing power 
  outages.
  
 

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Wind advisories are issued when sustained wind speeds of at least
40 mph and/or wind gusts over 45 mph are expected. Winds of this 
magnitude could cause minor damage to trees, power lines and 
weaker structures. Persons in the advisory area should secure all 
loose outdoor objects. If you are traveling through the advisory 
area keep a firm grip on the wheel, especially for those driving 
high profile vehicles.
