FLASH FLOOD WARNING
NATIONAL WEATHER SERVICE STATE COLLEGE PA
240 AM EST SAT NOV 9 1996
 
THE NATIONAL WEATHER SERVICE IN STATE COLLEGE HAS ISSUED A
FLASH FLOOD WARNING EFFECTIVE UNTIL  6 AM EST
FOR PEOPLE IN THE FOLLOWING LOCATIONS......
 
IN  PENNSYLVANIA
 
   ...TIOGA COUNTY
 
TIOGA COUNTY EMA OFFICIALS REPORT FLOODING CONTINUES TO BE A PROBLEM.
THOUGH THE HEAVY RAIN HAS MOVED EAST...LIGHT RAIN IS EXPECTED TO
CONTINUE THROUGH MORNING. THIS WILL CONTINUE TO CAUSE RUNOFF PROBLEMS
AND ALLOW FLOODING TO LAST INTO THE EARLY MORNING HOURS. WITH
THE RAIN TAPERING OFF...WATER LEVELS ARE EXPECTED TO BEGIN FALLING WITH
MOST AREAS SEEING FLOODING ABATE TOWARD SUNRISE.
 
DO NOT DRIVE YOUR VEHICLE INTO AREAS WHERE THE WATER COVERS THE
ROADWAY.  THE WATER DEPTH MAY BE TOO GREAT TO ALLOW YOUR CAR TO
CROSS SAFELY.  VEHICLES CAUGHT IN RISING WATER SHOULD BE
ABANDONED QUICKLY.  MOVE TO HIGHER GROUND.

Area forecast discussion, Nov 8, 9:31 PM EST, 5 hours 9 minutes before

CENTRAL PENNSYLVANIA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE STATE COLLEGE PA
930 PM EST FRI NOV 8 1996

BUSY NIGHT STARTING TO WIND DOWN AT THE OLD CTP TONIGHT.  WSR-88D
SHOWS RAIN NOW CONFINED TO EASTERN PORTIONS OF THE SUSQUEHANNA
VALLEY...AND CONTINUES TO MOVE EAST.

FLOOD WARNINGS CONTINUE FOR PORTIONS OF THE LOWER SUSQUEHANNA
VALLEY (YORK/LANC/LEB AND SCHUYLKILL) AS WELL AS TIOGA CO WHERE
MAJOR FLOODING CONTINUES WITH EVACUATIONS AND THE LIKE.

WAVE/FRONT CONTINUES TO SHOW SIGNS OF NEGATIVE TILTING...BUT IT
NOW SEEMS PCPN WILL CONTINUE TO PINWHEEL NORTHEAST OUT OF THE
AREA.  MODELS INDICATE THAT DVV/S OVERSPREAD MUCH OF THE AREA BY
06Z...AND THIS CORRESPONDS NICELY TO CURRENT RADAR PICTURE.
THERE CONTINUE TO BE SOME LIGHT RESIDUAL SHOWERS MOVING INTO THE
WEST...BUT FEEL THAT WESTERLY DOWNSLOPE FLOW WILL LIKELY PREVENT
MANY OF THESE SHOWERS FROM CARRYING INTO THE EASTERN COS.

PREVIOUS COORD WITH PIT HAVE AGREED TO DROP FLOOD WATCHES FOR THE
PIT ZONES.  PHL...FLOOD WATCHES ARE TRICKY.  I REALLY DO NOT
ANTICIPATE ISSUING ANY NEW FLOOD WARNINGS ATTM FOR ANY OF MY
COUNTIES.  HOWEVER...FLOOD WARNINGS FOR LOWER SUSQ COUNTIES WILL
CONTINUE TO MIDNIGHT OR BEYOND...WITH FLOODING CONTINUING.  I
THINK TIOGA WILL BE OUT ALL NIGHT.
