What happened

The episode as NWS PHI wrote it up.

Several days of heavy rain throughout the Delaware River Basin culminated with major flooding along the Delaware River from the 28th through the 30th. It was the fourth or fifth highest crest on record for the Delaware River along Bucks County and hit Yardley and New Hope the hardest. The crest was slightly lower than the April 2005 flood. President George W. Bush declared Bucks County a disaster area. Inland flooding affected Perkasie and Sellersville the most. Sporadic periods of heavy rain started on the 23rd, but the most widespread and heaviest rain fell from the night of the 27th into the morning of the 28th. Event totals in Bucks County averaged four to ten inches, but storm totals exceeded ten inches in parts of the Upper Delaware Basin in New York State.Governor Ed Rendell declared a disaster emergency in the state on the 28th. In Eastern Pennsylvania approximately 5000 homes, apartments and businesses were damaged. Many homes had their basement appliances and furniture ruined. The disaster area declaration made individual and public assistance possible. Numerous roads were damaged and closed. Even the Pennsylvania Turnpike in Montgomery County was closed. Between Bucks and Monroe Counties ten Delaware River bridges operated by the Delaware River Joint Toll Bridge Commission were closed. Tolls were suspended on bridges that remained open to ease congestion on the 28th through the 30th. Four bridges were still closed the night of the 29th, three bridges were closed on July 1st, they all were re-opened on the 2nd. Flooding damaged and forced the closure of twenty-two Pennsylvania State Parks. Emergency responders told people to not walk into flooded waters because it might contain sewage and other contaminants. Many homes also had oil in their basements from ruptured tanks. There was also concern about persons with individual wells having their drinking water compromised. An explosion of mold and mosquitoes was expected in the wake of the flood. Crops closest to the ground were also impacted by the flood and included cabbage, cucumbers, strawberries, spinach and squash. Bucks County took the worst hit from the flooding along the Delaware River with an estimated 30 million dollars in damage. Around 950 homes, 150 businesses, 150 apartments, 60 roads, 4 bridges, 5 parks and 3 public buildings were damaged. Around 250 homes and buildings, 50 businesses, four roads (River Road - Pennsylvania State Route 32 in particular), three bridges and two parks suffered major damage. Three homes were destroyed; two were in Lower Makefield Township. Upper Makefield Township had the greatest number of homes that suffered major damage, while Yardley Borough had the greatest number of homes that suffered any flood damage. New Hope Borough had the greatest number of businesses that suffered flood damage. About 4,000 people were evacuated from Yardley, New Hope, Solebury, Riegelsville, Perkasie, Lower Makefield and Upper Makefield Townships. Drinking water or filtration plants were closed in New Hope, Yardley, Sellersville and Morrisville. The Yardley plant did not come back on line until July 5th. Over 50 people were rescued from flood waters. Two kayakers were rescued from the Delaware River and one jet-skier was rescued from a tree. Flood damage also occurred inland along the Neshaminy Creek and the East Branch of the Perkiomen Creek. The Delaware Canal that was still damaged from the two previous floods in 2004 and 2005 was damaged further. Several county and municipal Independence Day functions were postoned.In Riegelsville Borough, nearly half of the homes were flooded, some up to the first floor. In Tinicum Township, nearly 100 feet of River Road (Pennsylvania State Route 32) was washed away. In Solebury Township, a Pennsylvania State Route 32 bridge was damaged over Milton Creek. In New Hope Borough, about 600 people were evacuated. As a precaution PECO Energy turned off gas and electric power to about 500 homes and 200 businesses. The exclusive Waterview Condos were evacuated. The flood waters reached the intersection of Waterloo and Mechanic Streets and also flooded Main Street. About 15 homes, 9 multi-family homes, 30 businesses and four apartment buildings suffered major damage. The Bucks County Playhouse suffered about one million dollars in flood damage. The famous Odette's Restaurant saw flooding reach halfway up the front door. It was one of the last businesses to reopen and was still closed about a month after the flooding. While it was reopened, the New Hope-Lambertville Bridge suffered the most damage of all of the Delaware River bridges and will need repairs. In Upper Makefield Township, about 200 people were evacuated. About 80 homes suffered major damage. Three businesses were also damaged. In Lower Makefield Township, over 75 homes were damaged and over 100 people were evacuated. The Robinson Place and River Glen neighborhoods were affected the most by the flooding. Except for the two destroyed homes, all evacuees were back in their homes by July 2nd. In Yardley Borough over 700 people were evacuated from the Rivermawr Section north of the Yardley Inn (which was flooded) and in the flats south of Afton Avenue between the Delaware Canal and the Delaware River. Waters from the canal and river met on the 29th. Homes on the north side of Afton Avenue were flooded on the 28th and the southern half of the borough was flooded on the 29th. Mud lines reached as high as 4.5 feet on the sides of homes. About three-quarters of the evacuees were able to return to their homes on the 30th. Some of the soil that was supporting the borough's sewer pipe line was carried away by underground rivulets. This caused cracks and breaks in the borough's sewer line underneath two streets that had to be replaced. Inland in Middletown and Northampton Townships, about 10 roads were closed because of flooding along both the Neshaminy and Little Mill Creeks. In Perkasie, flooding along the East Branch of the Perkiomen Creek forced the evacuation of residents of the Covered Bridge Apartments by raft. In Sellersville, both Main and Elm Street were flooded. This was described as the worst flooding in the area since Floyd in 1999.The Delaware River at Riegelsville was above its 22 foot flood stage from 451 a.m. EDT on the 28th through 632 p.m. EDT on the 30th.

AREA FORECAST DISCUSSION...UPDATED
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
1108 PM EDT TUE JUN 27 2006

.SHORT TERM /REST OF TONIGHT/...
HAVE MADE A QUICK UPDATE TO RESEMBLE CURRENT TRENDS. RIGHT NOW,
MOST OF NEW JERSEY AND PARTS OF EASTERN PENNSYLVANIA ARE NOT
SEEING MUCH RAINFALL, HOWEVER THERE ARE SOME SHOWERS DEVELOPING
AHEAD OF THE MAIN AREA OF RAIN IN CENTRAL/EASTERN PENNSYLVANIA,
MARYLAND, AND VIRGINIA. THIS AREA OF RAINFALL SHOULD PROGRESS ITS
WAY SLOWLY AS THE NIGHT CONTINUES. THERE IS STILL A FLASH FLOOD
WATCH FOR OUR WHOLE CWA AND A NUMBER OF FLASH FLOOD WARNINGS AS
WELL AS FLOOD WARNINGS FOR NUMEROUS RIVERS AROUND THE AREA.
PLEASE REFER TO THESE STATEMENTS FOR ANY FURTHER UPDATES TO

LOW MOVING ONSHORE IN NC. UPPER FLOW HAS NO WHERE FOR THE SYSTEM TO
GO EXCEPT THROUGH OUR CWA. THE CONVECTION FROM THE APPROACHING FRONT
AND THE TROP FEED WILL RAIN THEMSELVES OUT OVER OUR CFW.

MAIN CONCERN WILL BE WITH SOME OF OUR MOST VULNERABLE STREAMS THAT
FLOOD QUICKLY. WITH THE GROUND SATURATED AND THE RIVERS RUNNING
HIGH, THIS NEW HEAVY RAIN EVENT MAY CAUSE SOME TO COME OUT OF THEIR
BANKS DURING THE LATE NIGHT HOURS. THE NIGHTTIME MAKES THE SITUATION
FAR WORSE ESPECIALLY IF ANY RESCUES/SEARCHES ARE NECESSARY. SO
PLEASE LISTEN TO THE LATEST FORECASTS AND TAKE APPROPRIATE ACTION IF
YOU LIVE NEAR A STREAM. LATEST THINKING IS 3.5 INCHES OVER A WIDE
AREA AND PERHAPS SOME ISOLATED SPOTS IN EXCESS OF 6 INCHES.
CONDITIONS ACROSS THE REGION WILL NOT SUPPORT THIS AMOUNT OF RAIN
ESPECIALLY IN LESS THAN 12 HOURS. AS A RESULT, FLOODING WILL
CERTAINLY OCCUR ON THE SMALL FLASHY STREAMS.

THE SHORT TERM TO SPILL INTO THE LONG TERM AS REGION CONTINUES UNDER
DEEP TROUGH INITIALLY THEN BROAD CYCLONIC FLOW INTO THE WEEKEND.

ANTICIPATING MUCH CHANGE FROM GUID FOR TEMPERATURES.

AVIATION...
PREDOMINATELY MVFR CIGS AND P6SM VSBYS WORKING WELL WITH THE CURRENT

PERSISTENT SHOWERS (KABE AND KRDG). CONDITIONS DETERIORATE OVERNIGHT
WITH APPROACH OF LOW CENTER. IFR CONDITIONS ONCE THE RAINS BEGINS.
WINDS SWITCH AROUND FROM E OR SE TO SW TOMORROW AFTERNOON.

MARINE...
IN COORDINATIONS WITH AKQ, WE HAVE RAISED THE GALE FLAG FOR GUSTS
ALONG THE SOUTHERN NJ WATERS AND DE BAY. MODELS NOT PERFECT WITH THE
WIND SPEEDS WITH THE SYSTEM AND HIGHER THAN GUIDANCE WINDS SEEM THE
WAY TO GO WITH THIS ONE. SCA WILL REMAIN ALONG THE UPPER NJ COAST
FOR NOW, BUT WILL ADVISE THE NEXT SHIFT TO WATCH THINGS THERE.
CONDITIONS IMPROVE ONCE THE LOW MOVES AWAY WED AFTERNOON.
