What happened

The episode as NWS PHI wrote it up.

The combination of the remnants of Tropical Storm Ernnesto and a large high pressure system over eastern Canada produced heavy rain and strong winds in Chester and Delaware Counties. This caused power outages and downed trees. Rain moved into the area around Noon EDT on the 1st and did not exit until around 6 p.m. EDT on the 2nd. The heaviest rain fell during the day on the 2nd. Storm totals averaged around two inches. The heavy rain produced poor drainage flooding. In addition to the heavy rain, persistent east to northeast winds caused tree damage as the heavy rain loosened the root support and weighed down limbs. PECO Energy reported about 117,000 of its southeastern Pennsylvania customers lost power including those within Chester and Delaware Counties. In Chester County, about 50,000 customers lost power and in Delaware County, baout 18,500 customers lost power. Throughout PECO's service area, about 28,000 customers still did not have power restored as of 2 p.m. EST on the 2nd. In Delaware County, about 50 trees were knocked down and required repairs to about 350 lines. Trees blocked roadways in Haverford Township. In Upper Darby Township, the wind and rain knocked down a 350-year-old oak tree that subsequently damaged garages, a vehicle, pool deck and patio. In Chester County, downed trees closed roads in East Goshen Township. Actual storm totals included 2.28 inches in Valley Forge (Chester County), 2.14 inches in Exton and West Chester (Chester County), 2.04 inches in Glenmoore (Chester County),1.82 inches in Chadds Ford (Delaware County) and 1.52 inches at East Nantmeal Township (Chester County). Highest wind gusts included 40 mph at the Philadelphia International Airport. The low pressure system that was Ernesto moved slowly north from around Petersburg, Virginia at 5 p.m. EDT on the 1st, to near Fredericksburg, Virginia at 11 p.m. EDT on the 1st, passed close to Washington D.C. at 5 a.m. EDT on the 2nd, near Hagerstown, Maryland at 8 a.m. EDT on the 2nd, near Altoona, Pennsylvania at 2 p.m. EDT on the 2nd and accelerated northward and was just southeast of Buffalo, New York at 2 a.m. EDT on the 3rd. Of greater importance, was a strong high pressure system (greater than 1032 millibars) that remained over southeastern Canada and maintained the pressure gradient (difference) between it and the remnant low of Ernesto.

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
448 AM EDT SAT SEP 2 2006

.SHORT TERM /TODAY THROUGH MONDAY/...
THE MAIN FOCUS OF THE FORECAST REMAINS TO BE THE REMNANTS OF
ERNESTO AND HOW THEY ARE AFFECTING OUR AREA. WHAT IS LEFT OF
ERNESTO IS LOCATED JUST WEST OF THE SOUTHERN CHESAPEAKE BAY
WATERS AND MOVING VERY SLOWLY...IF AT ALL..NORTHWARD. THE HIGH
PRESSURE TO THE NORTH THAT IS SLOWLY MOVING SOUTHEAST IS COMBINING
WITH THE LOW PRESSURE CENTER TO CREATE A VERY TIGHT GRADIENT
MAKING FOR SOME VERY STRONG WINDS, ESPECIALLY ALONG THE COAST.
WEVE HAD REPORTS OF GUSTS OVER 70 MPH DURING THE NIGHT. THIS
SHOULD RELAX DURING THE DAY, BUT BEFORE IT DOES, WE ARE EXPECTING
WINDS TO STAY RATHER STRONG, MAINLY FOR COASTAL AREAS, THROUGH
MOST OF THE MORNING. THEREFORE, WE HAVE CONTINUED THE WIND
ADVISORY AND HIGH WIND WARNING WHERE THEY WERE PREVIOUSLY, AND
ALSO ADDED A FEW AREAS TO THE WIND ADVISORY AND HIGH WIND
WARNING. PLEASE REFER TO THESE STATEMENTS FOR PARTICULARS.

RAINFALL TOTALS HAVE RANGED FROM 3 TO 4 INCHES IN SOUTHERN
DELMARVA TO AROUND A HALF AN INCH IN NORTHERN NEW JERSEY. RAINFALL
WILL CONTINUE FOR MOST OF THE DAY FOR THE MAJORITY OF THE CWA
TODAY. WE HAVE DECIDED TO KEEP THE FLOOD WATCH UP FOR THE ENTIRE
AREA TODAY EVEN THOUGH TOTALS MAY NOT REACH AS PREVIOUSLY
EXPECTED. WE WILL MOVE THE EXPIRATION TIMES UP A FEW HOURS THOUGH.
THERE IS A STRONG THETA-E TONGUE IN WHICH SOME CONVECTIVE BANDED
PRECIPITATION HAS BEGUN TO FORM THIS MORNING IN THE SOUTHERN PART
OF THE DELMARVA WHICH COULD PRODUCE SOME HEAVY AMOUNTS WHERE
TRAINING TAKES PLACE. THIS WILL MOVE NORTHWARD THROUGH THE DAY AND
PROVIDE EXTRA RAINFALL WHERE RAIN HAS ALREADY FALLEN, SO THIS IS
THE MAIN REASON WE HAVE KEPT THE FLOOD WATCH UP.

AS THE HIGH TO OUR NORTH MOVES SOUTHEAST WARD, AND AN UPPER
LOW/TROUGH DIVES DOWN IN TO THE CENTRAL PART OF THE COUNTRY, THEY
WILL HELP STEER THE REMNANTS OF ERNESTO COMPLETELY OUT OF OUR
REGION BY SUNDAY. WE HAVE LEFT RAIN IN THE FORECAST THROUGH
LATE SATURDAY/EARLY SUNDAY MORNING, AND TAPERING FROM SOUTH TO
NORTH. WE HAVE LOWERED PRECIP TO SLIGHT CHANCE ON SUNDAY AND TAKEN
IT OUT FOR LABOR DAY AS IT LOOKS LIKE THEY MIGHT END UP BEING
PRETTY NICE DAYS. HOPEFULLY THE END OF THE LABOR DAY WEEKEND AND
LABOR DAY WILL BE NICER THAN IT STARTED.

&&

.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
CONTINUED TO FOLLOW HPC PROGS...WITH SOME CHANGES MADE TO THE
EXTENDED. THE EXTENDED STARTS OFF WITH SOME RELATIVELY NICE WEATHER
EVEN THOUGH A CHANCE FOR SHOWERS OR A POSSIBLE THUNDERSTORM EXISTS.
TEMPERATURES SHOULD REMAIN IN THE UPPER 70S TO LOW 80S, WITH THE
POCONOS REGION STAYING IN THE LOWER 70S. A LOW PRESSURE SYSTEM IS
EXPECTED TO MOVE THROUGH THE AREA ON WEDNESDAY INTO THURSDAY,
BRINGING THE NEXT CHANCE FOR RAINFALL ACROSS THE REGION.

&&

.AVIATION...
AT 4:00 AM, CEILINGS RANGED MAINLY FROM 1000 TO 2500 FEET AT OUR
TAFS SITES.  VSBY VALUES WERE NOT FALLING MUCH BELOW 4 MILES IN RAIN
SHOWERS AS A NORTHEAST WIND CONTINUED TO DRAG SOME DRY LOW LEVEL AIR
DOWN FROM NEW ENGLAND.

NOT MUCH CHANGE IS EXPECTED DURING THE EARLY MORNING HOURS, EXCEPT
THAT THE HIGHEST WIND SPEEDS AND GUSTS SHOULD WORK THEIR WAY
NORTHWARD THROUGH THE PHL METRO AREA DURING THE HOURS AROUND
DAYBREAK, AND UP INTO THE LEHIGH VALLEY AROUND MID MORNING.

AS THE DAY PROGRESSES, THERE WILL BE A TREND TOWARD DIMINISHING WIND
SPEEDS FROM SOUTH TO NORTH AND THE WIND DIRECTION SHOULD VEER
AROUND TO THE SOUTHEAST THEN SOUTH.  CEILING HEIGHTS WILL BE A
LITTLE SLOWER TO IMPROVE, THOUGH ITS POSSIBLE THAT ALL EIGHT OF OUR
TAF SITES WILL RETURN TO VFR CONDITIONS BY LATE IN THE DAY.

&&

.MARINE...
AS THE TIGHTER SURFACE GRADIENT AND THE LOW LEVEL JET SHIFT
NORTHWARD, WEVE MOVED OUR STORM WARNING UP TO OUR COASTAL WATERS
FROM GREAT EGG INLET TO SANDY HOOK.  FOR OUR WATERS SOUTH OF GREAT
EGG INLET AND FOR DELAWARE BAY WEVE LOWERED THE STORM WARNING TO A
GALE WARNING.

CONDITIONS SHOULD SLOWLY IMPROVE STARTING TODAY, WITH WIND SPEEDS
DROPPING BELOW SMALL CRAFT ADVISORY CRITERIA FOR TONIGHT.  WAVES ON
OUR OCEAN WATERS WILL TAKE A LITTLE LONGER TO DROP BELOW THE SMALL
CRAFT ADVISORY CRITERIA OF 5 FEET.  THAT PROBABLY WONT TAKE PLACE
UNTIL MONDAY.

&&

.TIDES...
UNTIL WE LOSE THE STRONG ONSHORE FLOW WELL LIKELY CONTINUE TO SEE
SOME SPOTTY MINOR TIDAL FLOODING AS WATER REMAINS UNABLE TO DRAIN
OUT OF THE BAYS AND ESTUARIES OF DELAWARE AND NEW JERSEY.

AS FAR AS CHESAPEAKE BAY IS CONCERNED, THE REMNANTS OF ERNESTO ARE
NOT CREATING MUCH OF A SURGE UP THE BAY.  AS A RESULT, WELL SIMPLY
MENTION THE POSSIBILITY OF SPOTTY MINOR TIDAL FLOODING FOR THE UPPER
EASTERN SHORE AS WELL.

&&

.SURF...
AFTER THE WIND SPEEDS SUBSIDE A BIT TODAY, IT WILL TAKE MUCH OF
TONIGHT AND SUNDAY FOR SEAS TO SETTLE DOWN A BIT.  AS A RESULT,
WELL EXTEND THE HIGH SURF ADVISORY UNTIL EARLY SUNDAY MORNING.

&&

.HYDROLOGY...
STORM TOTAL AMOUNTS HAVE RANGED FROM 3 TO 4 INCHES IN SOUTHERN
DELMARVA, TO AROUND A HALF AN INCH IN NORTHERN NEW JERSEY. THIS HAS
NOT CAUSED ANY MAJOR PROBLEMS ALONG AREA RIVERS AND STREAMS YET,
ALTHOUGH SOME HAVE SEEN SOME HIGH RISES SO FAR. THERE COULD BE
ANOTHER 1 TO 2 INCHES WITH SOME ISOLATED HEAVIER AMOUNTS POSSIBLE IN
TRAINING AREAS OF RAINFALL, SO WE HAVE KEPT THE FLASH FLOOD WATCH.
NO WARNINGS HAVE BEEN ISSUED YET AS AREA WATERWAYS ARE EXPECTED TO
REMAIN BELOW FLOOD STAGE.  OF COURSE, THIS IS DEPENDENT ON THAT WE
DO NOT GET ANYMORE SIGNIFICANT RAINS.  IF THINGS CHANGE, STATEMENTS
WILL BE ISSUED AS NEEDED.
