...SHORT LIVED WATER SPOUT ON THE LOWER SUSQUEHANNA RIVER...

A REPORT FROM THE POWER PLANT AT PEACHBOTTOM IN LANCASTER COUNTY
INDICATES THAT A SHORT LIVED WATER SPOUT DROPPED OUT OF A RAIN SHOWER
THAT WAS PASSING THROUGH THE AREA. POWER PLANT WITNESSES DESCRIBE A
FUNNEL THAT DROPPED OUT OF THE CLOUD AND MADE CONTACT WITH THE WATER
SURFACE...THEN MOVED APPROXIMATELY 1000 YARDS UP RIVER BEFORE LIFTING
BACK INTO THE CLOUDS AND DISSIPATING. THEY REPORT THAT THE WATER
SURFACE WAS CHURNED UP AROUND THIS FEATURE AND ALSO THAT NO DAMAGE WAS
DONE.

STATE COLLEGE DOPPLER RADAR SHOWED ONLY WEAK TO MODERATE RAIN SHOWER
ACTIVITY IN THE VICINITY OF PEACHBOTTOM AT THE TIME OF THE REPORT.
DOPPLER PRODUCTS FROM THE RADAR SHOWED NO EVIDENCE OF A TORNADO. IT IS
LIKELY THE FUNNEL WAS A WEAK SHORT LIVED LOCAL PHENOMENA THAT IS NOT
UNCOMMON DURING UNSTABLE ATMOSPHERIC CONDITIONS. THESE SYSTEMS SELDOM
LAST MORE THAN A FEW MINUTES AND ALMOST NEVER DO ANY DAMAGE.

CONDITIONS DO FAVOR MORE SHOWERS AND THUNDERSTORMS FOR THE REMAINDER OF
THE AFTERNOON OVER EASTERN PENNSYLVANIA. THE PRIMARY THREAT FOR THE
REST OF THE AFTERNOON AND NIGHT TIME HOURS IS LIKELY TO BE HEAVY RAIN.

THESE WEAK WATER SPOUTS ARE USUALLY SHORT LIVED. THEY HAVE HOWEVER...ON
OCCASION TOUCHED THE GROUND AND CAUSED DAMAGE.  BECAUSE OF THIS
POSSIBILITY...YOU SHOULD SEEK A SAFE INDOOR SHELTER WHEN THESE FUNNELS
ARE OBSERVED.
