What happened

The episode as NWS PHI wrote it up.

For the second time within seven months a greater than 50-year storm affected the Delaware River Basin and its tributaries. But, this time flooding also extended into the Passaic River Basin. In all, about 6,000 persons were evacuated along the Delaware and Passaic River Basins in New Jersey with about 3,200 homes damaged. New Jersey Acting Governor Richard J. Codey declared a state of emergency on April 3rd. Many homes and businesses that were flooded because of the remnants of Hurricane Ivan along the Delaware River, were flooded again. The crests along the Delaware River were even higher than in September 2004 and were the highest crests since 1955. In many places, it was the second or third highest crest on record for the Delaware River. In Sussex, Warren, Hunterdon, Mercer and Morris Counties, about 1,800 homes and businesses were flooded, 25 homes were destroyed. Many of the homes and businesses that were flooded, had flooding into the first floor of their dwellings. About 4,000 people were evacuated from the five counties. Shelters were opened in schools, fire houses and churches. Both the Red Cross and Salvation Army assisted with the evacuations and distributing food and drinks. Many major roads were closed. A dozen low-lying bridges from Trenton north were closed and damaged by the flooding. Total statewide damage from this storm was estimated at $52 million dollars. The worst damage was reported in Lambertville (Hunterdon County) and Trenton (Mercer County). Miraculously there were no deaths or major injuries. Residents and businesses found raw sewage that backed into water-logged cellars. Many furnaces, water heaters, electrical panels, washing machines and dryers were destroyed. In many places, everything that was stored below ground level was destroyed. The flood waters dislodged propane and oil tanks. Some basements were contaminated with oil. First floor damage included ruined hardwood floors, furniture, carpeting, vinyl flooring and dry walls. The homes that were greatly affected had their electricity and gas service turned off and in many instances had to get the former replaced. Private wells had to be tested for contamination. The heavy rain loosened the ground and caused trees to be knocked down and carried down river along with waste receptacles, propane tanks and beer kegs. As river levels rose, they damaged the low-lying bridges across the Delaware River. Damage to the bridges was estimated at $1.5 million with the greatest damage and longest closure to the Washington Crossing Bridge between Bucks and Mercer Counties. On April 19th, President George W. Bush declared a major disaster area in Gloucester, Hunterdon, Mercer, Morris, Sussex and Warren Counties. This opened the door for federal aid for homeowners and businesses. Persons could get grants for temporary housing and to clean and rebuild their homes. Homeowners and businesses were now eligible for low interest loans to cover uninsured property losses and other federally funded programs.Hunterdon County was the hardest hit of all of the New Jersey counties with Lambertville Borough the hardest hit municipality. The rain began falling around Midnight EST on the 2nd and fell heavy at times from the middle of the morning into the evening. Lighter rain and/or drizzle fell through the rest of the night and ended during the morning of the 3rd. Storm totals averaged three inches. About 1,100 people were evacuated from every municipality along the Delaware River except for West Amwell Township. Tributaries to the Delaware River also flooded. Inland, flooding also occurred along the branches of the Raritan River. Five homes were destroyed, about one hundred forty-five homes and businesses suffered major damage and about another five hundred homes and businesses suffered some damage. Lambertville, Frenchtown, Stockton and Milford Boroughs were affected the most by the flooding along the Delaware River. In Lambertville, the Delaware River merged with the Delaware and Raritan Canal. Swan Creek also flooded. Flood waters ripped through the first floor of the Justice Complex and ruined some court records. About 200 homes were damaged as first floor flooding occurred. South Union Street and Lambert Lane were hit the hardest. In Frenchtown Borough about 50 homes suffered substantial damage as did the borough's post office. It was expected to be closed for one to two months. The sewage treatment plant was also damaged. Four hundred feet of River Road was washed away. New Jersey State Route 29 between Frenchtown and Lambertville was closed. In Stockton, the locks in the canal at Prallsville Mills broke and sent Delaware River water into the borough. Five homes on Mill Street were condemned as the water blew out some back doors. Fifteen to twenty families had to wait for repairs before returning to their homes. In Alexandria Township, mudslides tore down trees and wires. In Kingwood Township, sheds were ripped from their foundations. Docks and canoes floated downstream. The Musconetcong River also flooded along the Hunterdon and Warren County border. In the Delaware River itself, flooding at the Treasure Island Boy Scout Camp forced the closure of the facility for the year. Electrical transformers and interior buildings were ruined. Many of the free bridges across the Delaware River were closed on the third and did not re-open until the 6th. In downtown Clinton, flooding along the South Branch of the Raritan River flooded the Hunterdon Museum of Art. The Delaware River at Riegelsville (Bucks County) crested at 34.07 feet at 6 a.m. EDT on the 4th. This was also the third highest crest on record and the highest crest since August 20, 1955. It was above its 22 foot flood stage from 1201 a.m. EDT on the 3rd through 1141 a.m. EDT on the 5th. The Delaware River at Frenchtown was above its 16 foot flood stage from 8 a.m. EDT on the 3rd through 636 a.m. EDT on the 5th. It crested at 21.8 feet at 8 a.m. EDT on the 4th. This was the fourth highest crest on record and the highest since August 20, 1955. The Delaware River at Stockton was above its 18 foot flood stage from 3 a.m. EDT on the 3rd through 645 a.m. EDT on the 5th. It crested at 26.75 feet at 11 a.m. EDT on the 4th. This was the second highest crest on record and the highest since August 20, 1955. The Delaware River at the New Hope/Lambertville Bridge was above its 13 foot flood stage from 846 a.m. EDT on the 3rd through 814 a.m. EDT on the 5th. It crested at 19.6 feet at 11 a.m. EDT on the 4th. This was the third highest crest on record and the highest since August 20, 1955. The South Branch of the Raritan River at High Bridge was above its 10 foot flood stage from 718 p.m. EST on the 2nd through 907 a.m. EDT on the 3rd. It crested at 10.71 feet at 315 a.m. EDT on the 3rd. Farther downstream, the South Branch of the Raritan at Stockton was above its 8 foot flood stage from 6 p.m. EST on the 2nd through 357 p.m. EDT on the 3rd. It crested at 10.10 feet at 11 p.m. EST on the 2nd. Specific storm totals included 3.92 inches in Califon, 3.62 inches in Flemington, 3.26 inches in Milford and 2.20 inches in East Amwell Township. The flooding heavy rain was caused by a low pressure system that moved from the southern Gulf Coast States on the morning of April 1st northeast to the eastern Tennessee Valley during the evening of the 1st, to far western Virginia just after Midnight EST on the 2nd, into central Virginia at 7 a.m. EST on the 2nd, near Washington, D.C. at 1 p.m. EST on the 2nd, near Lancaster, Pennsylvania at 7 p.m. EST on the 2nd, near Scranton, Pennsylvania at 1 a.m. EST on the 3rd, over the Finger Lakes in New York at 8 a.m. EDT on the 3rd and into eastern Lake Ontario at 2 p.m. EDT on the 3rd. The strong southeast flow preceding the low pressure system was able to entrain Atlantic Ocean moisture in addition to the Gulf of Mexico moisture into the system. The southeast flow also was ideal for orographic lifting in the Poconos and other higher terrain. The flooding was exacerbated by the already wet soil conditions due to heavy rain on both March 23rd and 28th. In addition, along the Delaware River, snowmelt in the upper basin in New York State and because the New York City Delaware County, New York reservoirs were already at capacity added to the flooding.

Area forecast discussion, Apr 2, 4:07 PM EST, 1 hour 53 minutes before

AREA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE MOUNT HOLLY NJ
407 PM EST SAT APR 2 2005

.SHORT TERM (TONIGHT THROUGH MONDAY)...
MODERATE TO HEAVY RAINFALL WAS OCCURRING IN ADVANCE OF THE
COLD/OCCLUDED FRONT THAT LINED UP WELL WITH THE MID LEVEL DRY SLOT
SHOWING UP ON GUIDANCE AND ON SAT PIX. FAIRLY DEEP SERLY FLOW, A
DROP IN EQUIV POT TEMP WITH HEIGHT ABOVE THE SFC LAYER, AND AN
IMPRESSIVE PLUME OF MOISTURE OUT OF THE GULF ALL COMING TOGETHER TO
PRODUCE FLOODING RAINS. WE HAVE TRIED TO TIME IT ALL WITH REGARD TO
THE FORECAST, WITH THE FLOOD WATCH TIMED INTO THE EVENING CLOSER TO
THE BACK EDGE OF THE PCPN AND FOR TOINGHT FURTHER NE. LOOKS THAT THE
SRN ZONES WILL BREAK OUT OF THE STEADY RAIN BY EVENING, BUT APPROACH
OF UPPER LOW SHOULD BRING BACK SHOWER ACTIVITY OVERNIGHT. SOME OF
THE VERY STRONG WINDS OFF THE SURFACE ARE MAKING IT DOWN TO THE
SURFACE, BUT WE BELIEVE THE SHALLOW MARINE LAYER INDICATED BY MODEL
SOUNDINGS PRECLUDE SYNOPTIC SCALE SUSTAINED WINDS AND GUSTS IN THE
WIND ADVISORY CRITERIA, AND WE HAVE OPTED TO HANDLE ANY STRONGER
WINDS AND GUSTS WITH SHORT FUSED PRODUCTS. TEMPS HAVE RISEN NICELY
WITH THE PASSAGE OF THE WARM FRONT, BUT SHOULD DROP AGAIN AS UPPER
LOW MOVES CLOSE TO THE AREA OVERNIGHT.

TOMORROW THE SLOW MOVEMENT OF THE UPPER LOW MADE US KEEP SHOWER
ACTIVITY IN ALL ZONES, RANGING FROM CHANCE DOWN SOUTH TO CATEGORICAL
UP NORTH. WE PRESENTLY BELIEVE PRECIPITATION AMOUNTS AFTER TONIGHT
SHOULD DROP CONSIDERABLY, BUT ANY RAIN WOULD BE UNWELCOME AFTER WHAT
WE ARE GETTING THIS AFTERNOON INTO TONIGHT. WE SHOULD CERTAINLY SEE
THE CONVECTIVE TEMPERATURES REACHED, CONSISTENT WITH THE SHOWER AND
CLOUD FORECASTS. THOSE ARE RATHER COOL AND SUBSEQUENTLY WE WENT WITH
COOLER STAT GUIDANCE.

THE LOW LIFTING OUT LEAVES ONLY THE FAR NWRN ZONES WITH PCPN CHANCES
TOMORROW NIGHT, BUT GIVEN SOUNDINGS HAD TO MENTION THE PSBLTY OF
SNOW SHOWERS AFTER MIDNIGHT. DRYING US OUT FOR MON, WITH H8 TEMPS
CONSISTENT WITH PREV FORECASTS AND STAT GUIDANCE.

&&

.LONG TERM (MONDAY NIGHT THROUGH SATURDAY)...
NO SIG CHANGES WERE MADE TO THE EXTENDED. THE PREV AFD DISCUSSION:
A BRIEF PERIOD OF DRY WEATHER IN STORE FOR MID WEEK AS HIGH PRESSURE
BUILDS TO THE MID ATLANTIC, BUT ANOTHER LOW WILL BE WRAPPING UP OVER
THE LAKES AND PULLING IN SOME COLDER AIR WHICH AGAIN WOULD LEAD TO A
MENTION OF RAIN/SNOW SHOWERS. OTHER THAN THAT, DONT PLAN ON GETTING
MUCH MORE DETAILED WITH IMMEDIATE THREAT AT HAND. THIS NEXT SYSTEM
WILL NOT HAVE THE QPF POTENTIAL, BUT WELL HAVE TO SEE EXACTLY WHAT
FALLS BY SUNDAY MORNING AND EVEN A HALF INCH COULD BRING ADDITIONAL
PROBLEMS IN SOME VULNERABLE AREAS.

&&

.AVIATION...
IFR CONDITIONS WILL REMAIN ACROSS THE REGION AT LEAST THE NEXT
COUPLE HOURS ACROSS OUR SOUTHERN ZONES AND INTO THE EVENING HOURS
FURTHER NORTH. A DRY SLOT, CURRENTLY WORKING UP INTO THE VIRGINIAS,
IS EXPECTED TO MOVE INTO THE AREA. WRAP AROUND MOISTURE ASSOCIATED
WITH THE MID-LEVEL LOW WILL AFFECT THE REGION TOWARD DAYBREAK. ONCE
WE LOSE THE IFR CONDITIONS TONIGHT, MVFR SHOULD BE COMMON THROUGH
SUNDAY AFTERNOON.

&&

.MARINE...
BASED ON PORTS DATA AND SURROUNDING LAND-BASED OBSERVATIONS, GALES
HAVE BEEN ISSUED FOR THE UPPER BAY. NO CHANGES WITH THE HEADLINES
ELSEWHERE. GALES ARE EXPECTED TO TRANSITION TO SCAS ON SUNDAY.

THE AREA OF LOW PRESSURE RESPONSIBLE FOR THE WINDS WILL INTENSIFY
OVER VIRGINIA AND MOVE NORTHEAST INTO PENNSYLVANIA TONIGHT AND THEN
NEW YORK STATE ON SUNDAY. HIGH PRESSURE WILL SLOWLY BUILD OVER THE
MARINE AREA MONDAY THROUGH TUESDAY NIGHT. LOW PRESSURE WITH A
FRONTAL ZONE WILL APPROACH FROM THE WEST WEDNESDAY NIGHT OR
THURSDAY.

&&

.HYDROLOGY...
RAINFALL AMOUNTS AROUND THE AREA THROUGH 300 PM WERE GENERALLY IN
THE 1.50 TO 2.00 INCH RANGE, WITH THE BACK EDGE COINCIDING WITH THE
MID LEVEL DRY SLOW JUST NE OF THE VIRGINIA NORTHERN NECK. GIVEN
TIMING OF BACK EDGE, TOTALS GENERALLY IN THE 2.00 TO 4.50 INCH RANGE
SEEM POSSIBLE AND CERTAINLY WARRANT CONTINUATION OF THE WATCH. POOR
DRAINAGE FLOODING, SMALL STREAM AND CREEK FLOODING, LARGER STREAM
FLOODING AND ULTIMATELY RIVER FLOODING ARE ALL ON THE TABLE, WITH
SOME OF THAT FLOODING POSSIBLY MAJOR IN NATURE.

INTENSIFYING LOW PRESSURE MOVING THROUGH THE CENTRAL MID ATLANTIC
REGION THIS EVENING WILL MOVE NORTH INTO PENNSYLVANIA TONIGHT AND
THEN NORTHEAST INTO EASTERN NEW YORK STATE BY SUNDAY EVENING.

GALE FORCE WINDS OVER THE COASTAL WATERS WILL PERSIST THROUGH MOST
OF TONIGHT ALONG THE NEW JERSEY AND DELAWARE COASTS. WIND DIRECTIONS
WILL SHIFT FROM SOUTHEAST TO SOUTHWEST BY MORNING, BUT A MOSTLY
ONSHORE FLOW WILL PREVAIL FOR MUCH OF TONIGHT.

ABOVE NORMAL TIDES WILL RESULT, AND THIS COULD PRODUCE MINOR TIDAL
FLOODING AROUND THE TIME OF HIGH TIDE TONIGHT ON THE DELAWARE AND
NEW JERSEY OCEANFRONTS. FLOODING MAY ALSO OCCUR ON DELAWARE BAY AND
FURTHER UP ON THE DELAWARE RIVER AS THE STRONG SOUTHEAST TO SOUTH
WINDS CONTINUE TO PUSH IN THE WATER. HIGH TIDE ALONG THE DELAWARE
AND NEW JERSEY OCEANFRONT WILL OCCUR FROM 3 TO 5 AM. HIGH TIDE
OCCURS LATER ON THE BAYS AND TIDAL RIVERS AND STREAMS. ALTHOUGH WIND
DIRECTIONS ARE NOT IDEAL FOR TIDAL FLOODING ALONG THE RARITAN
BAYSHORE, MINOR TIDAL FLOODING MAY ALSO OCCUR THERE TONIGHT.

DO NOT DRIVE THROUGH FLOOD WATERS, THE WATER MAY BE DEEPER THAN YOU
THINK IT IS.  ALSO, DO NOT PARK YOUR VEHICLE AT A LOCATION THAT IS
PRONE TO TIDAL FLOODING. REMEMBER...TURN AROUND...DONT DROWN.
