| Brief Description: A strong tornado (F2 on the Fujita Scale) struck extreme northern Manalapan and extreme southwest Marlboro Townships. Four houses had severe roof damage and about a dozen others suffered minor damage. A construction trailer was tossed and two vehicles were overturned. Between 150 and 200 trees were either uprooted or damaged. Tree damage was so extensive that Hawkins Road Park was closed. The area was littered with broken pieces of wood, shingles, gutters and parts of roofs. The tornado's path length was about 1.5 miles and its path width was around 200 feet. No injuries were reported. This was the first strong tornado in New Jersey since August 20, 1999 and the first strong tornado in Monmouth County since October 16, 1955. The tornado first touched down near Arbach Lane in Manalapan Township. It initially was relatively weak (F0) on the Fujita Scale, but intensified into an F1 tornado before it reached Kentucky Court. One property on Kentucky Court lost dozens of trees. The tornado also downed trees on Ivanhoe and Rowena Roads. The tornado reached its maximum strength (F2) as it passed through Debracy Court where the worst damage occurred. Four homes suffered severe roof damage. The roof and second floor of one home had to be completely repaired. The windows of another house all burst. A restored Thunderbird was damaged by flying debris that penetrated the garage door. The house apparently shifted as doors no longer closed. A third home on the block had a picnic table blown into its sunroom along with a piece of the neighbor's fence. Patio furniture was splintered throughout the block. A minivan parked in one driveway, was rolled about 40 feet. The tornado weakened to an F1 after it left Debracy Court. Nevertheless, it tore shingles from a home on Eastwood Boulevard and downed a tree onto a car. A construction trailer on Hawkins Corner Road was blown 50 feet across the street and crushed like an aluminum can. As the tornado crossed into Marlboro Township, it knocked down dozens of trees in Hawkins Road Park. The part was closed because of the uprooted trees. As the tornado exited the park, it weakened to an F0. It still knocked a tree onto a house on MacLeisch Drive and ripped shingles and gutters from homes on Guest and MacLeisch Drives. The tornado lifted as it approached Barclay Brook. | |||||||||||

| Brief Description: EVENT NARRATIVE: An EF-2 tornado with estimated maximum wind speeds of 120 mph touched down and affected Hamilton and Stroud Townships. The highest wind speeds and worst reported damage occurred on Middle Road in Hamilton Township and Stroudsmoor Road in Stroud Township. Two men were injured and about 10,000 homes and businesses lost power. Hundreds of trees were destroyed and at least 25 telephone poles had to be replaced. Power was not fully restored until the 31st. In Hamilton Township, two homes suffered roof damage and four large farm buildings and one garage were destroyed. In Stroud Township, one home lost its roof, two others had trees on their roofs and a section of a resort building lost its roof. This was the first reported tornado in Monroe County since July 1, 2001 and the first reported EF2 or F2 tornado in the county since October 5, 1979. The tornado touched down southwest of Kemmertown Road in Hamilton Township before causing substantial damage to the Blakeslee Farm near the intersection of Middle and Blakeslee Roads. On Kemmertown Road, a downed tree damaged a porch at an assisted living facility. At the Blakeslee Farm, the tornado destroyed three barns and a garage shed and took the roof and attic off of the home. A 46-year-old man suffered facial and rib injuries and a 66-year-old man suffered a head injury as the garage shed collapsed. In addition to the property damage, the tornado damaged the corn, hay, wheat and oat crops on the farm. Thirty percent of the trees on the property were destroyed . The tornado then lifted, causing only relatively minor damage as it followed Middle Road into Stroud Township. However, more substantial damage again occurred from Larsens Lane northeast to Fox Run Road and Essig Lane. More damage occurred as the tornado crossed Stroudsmoor Road, where numerous trees were felled, and roof damage occurred to the Stroudsmoor Country Inn. A downed tree also damaged a home on Stroudsmoor Road. Another downed tree damaged a home on Pennsylvania State Route 191. The tornado lifted just before it moved over the intersections of Routes 191 and 611 (Foxtwon Hill Road) just south of Stroudsburg. The tornado was on the ground for about 4.6 miles and its maximum width was about 100 yards. Damage was estimated at 1 million dollars. EPISODE NARRATIVE: A warm front retreating to the north and a cold front approaching from the west produced strong to severe thunderstorms across eastern Pennsylvania during the afternoon of the 29th. One EF-2 tornado also occurred. | |||||||||||

| Brief Description: A tornado ripped through Upper and Lower Moreland Townships as well as extreme northeast Philadelphia during the early morning of June 1st. The tornado was rated as an F1 (A weak tornado on the Fujita Scale) in Montgomery County and intensified into an F2 (or strong tornado on the Fujita Scale) within Philadelphia. The worst damage occurred within the unoccupied Byberry Industrial Park as the tornado reached its strongest intensity. Thirty-five commercial buildings were damaged, nine severely. Damage outside of the industrial park was mainly confined to downed trees. About ten homes were damaged by fallen trees. The damage within Philadelphia was discontinuous suggesting the tornado was not on the ground for its entire lifetime across the city. Damage was estimated at $1.8 million dollars. Because the buildings were unoccupied, no injuries occurred. The tornado moved into the city from Lower Moreland Township in the Bustleton/Lumar Park area around 120 a.m. EDT. Trees were split and knocked down. The tornado intensified into a strong one (F2 on the Fujita Scale) as it crossed into the Byberry Industrial Park. The worst damage was done in the area around Byberry Road, McNulty Road, Roosevelt Boulevard and Southampton Road. Five ton air conditioning units were tossed. Of the 35 commercial buildings damaged, nine were severely damaged and declared "imminently dangerous". Slabs of the roof were tossed 200 yards. Some buildings lost entire sides, had buckled steel beams, shattered windows and crushed equipment. The tornado plucked utility poles from the ground. About 20 poles were knocked over. Five teams of tree service personnel were overwhelmed. Damage south of the industrial park became sporadic as the tornado turned toward the southeast. It lifted just before the Bucks County border near Woodhaven Road just to the southeast of the Franklin Mills Mall. Its path length was about 5.6 miles and path width about 200 yards. PECO Energy reported 34,000 customers in Philadelphia lost power. Five thousand still did not have power the evening of the 1st. It was the worst non-winter storm in PECO Energy's 50 year history and the fourth worst overall. According to their lightning detection system, there were 7,000 cloud to ground lightning strikes in their service area as this line of thunderstorms moved through. | |||||||||||

| Brief Description: EVENT NARRATIVE: This circulation intensified as it moved east across the Verrazano Narrows. The tornado re-developed by the time the circulation moved on shore in Brooklyn. Damage in the form of fallen trees and structural roof damage occurred in Bay Ridge starting in the area from Shore Road between 71st and 78th Streets eastward to Bay Ridge Blvd. This occurred at approximately 6:32 am. The tornado may have briefly lifted and then touched down again on Bay Ridge Avenue between 3rd and 4th Avenues, and continued on an east-northeast path across 68th Street between 3rd and 4th Avenues. Eleven homes in this section had moderate to severe roof damage. The storm continued to move east-northeast into Leif Ericson Park Square, where severe damage to trees occurred. As the tornado lifted, it tore off the roof of the Nissan car dealership at the corner of 66th Street and Fifth Avenue. The tornado returned to the ground farther northeast, with scattered tree damage along 6th avenue. Based on the assessed damage in Bay Ridge, this tornadic damage is classified as EF-2 with estimated wind speeds of 111 to 135 mph. The tornado returned to the ground as another pocket of significant damage occurred on 58th Street between 5th and 6th Avenues. The roof was ripped off of 5 homes, and tree damage indicated strong EF-1 damage. The tornado then headed east, and touched down for at least the fourth, but final time, in Kensington just east of the intersection of Church Avenue and Beverly Road at approximately 6:40 am. Numerous trees, approximately 30, were uprooted along Ocean Parkway as the tornado moved east. The tornado produced significant damage to trees and structures in the area with East 8th and 7th Streets being hit hard. Damage was reported as far east as Argyle Road. The tornado was on the ground for approximately 1/2 mile in this area before it lifted. EPISODE NARRATIVE: An approaching cold font, interacting with energy aloft, produced numerous thunderstorms, including one which produced two tornadoes across Southern New York City, and later produced wind damage in Nassau County. In addition, the storms produced copious amounts of rainfall which caused widespread significant flash flooding in New York City, including several subway lines, and Long Island. | |||||||||||

| Brief Description: A tornado touched down in northwestern Northampton County near Danielsville at about 340 pm EST. It remained on the ground for about two miles and lifted prior to moving over the Blue Mountain Ridge which is the dividing line between Northampton and Monroe Counties. One person was injured and two families were made homeless after their homes were destroyed. About a dozen homes were damaged, two were destroyed, three vehicles were damaged or destroyed and significant roof damage occcurred to the Salem United Methodist Church. Damage estimates were around $250,000. The tornado was rated an F2 (or strong tornado with wind estimates between 113 and 157 mph) on the Fujita Scale. Lehigh Township was declared an emergency area. The tornado touched down near the Blue Mountain Road just south of Pennsylvania State Route 946. One of the first buildings in its path was the Salem United Methodist Church which lost part of its roof and a vehicle near the church was destroyed. It proceeded eastnortheast through Danielsville. An elderly woman was injured when the tornado struck the mobile home she was in and pushed it off its foundation. Another unoccupied 70 foot by 14 foot mobile home was tossed into a ditch 50 feet away. The roof of another house was found 100 feet downwind. A playhouse and a metal school bus shelter were deposited in the trees. Numerous trees were either snapped or damaged, but the majority of damage to other homes along the periphery of the tornado's path was limited to windows and chimneys. Prior to the tornado's touch down, the same parent thunderstorm did produce some damaging winds in Treichlers along Long Lane Road. | |||||||||||

| Brief Description: EVENT NARRATIVE: An EF-2 tornado touched down in Wantage Township at about 248 p.m. EDT on the 29th. It was the first confirmed tornado in Sussex County since August of 1990, the first tornado of F2 or EF2 strength ever in the county since records started in 1950 and the first tornado to reach EF2 or F2 strength in New Jersey since the Manalapan tornado of May 27, 2001. The tornado remained on the ground for 6.6 miles before it crossed the border into New York State. Its maximum width was about 100 yards and its highest estimated wind speed was 120 mph. The tornado damaged thousands of trees, decimated acres of farmland and some rural property. The tornado touched down near the intersection of Route 519 and Rutgers Road, then crossed Libertyville Road, Snoyer Road and Ramsey Road, producing minor tree and limb damage along the way. More substantial damage, mainly in the form of downed trees and some minor structural damage, occurred after the tornado crossed New Jersey State Route 23 near its intersection with Unionville Road and Rose Morrow Road. The worst damage of the entire tornado occurred along Beemer Road and on the north side of New Jersey State Route 23. Substantial damage occurred to the Ricker Farm, as two barns and one silo were destroyed. Two other barns suffered severe wind damage. Some minor damage also occurred to the adjacent farmhouse. Pieces of one barn roof were found three quarters of a mile away. A two week old calf was killed by the flying debris, two others were thrown fifty feet, but not seriously hurt. Damage estimates for the Ricker farm reached as high as $500,000. Hundreds of trees were felled further north along Beemer Road, and power was out for several hours as power lines were brought down by the tornado and falling trees. The tornado weakened after it crossed Wolfpit Road and Black Dirt Road on its way into New York State. On Wolfpit Road, it ripped the porch from a home and lifted a boat and carried it one quarter of a mile away. A vineyard in the township was also damaged. The tornado crossed into Orange County, New York near Quarry Road as an EF-1. No other deaths or injuries were reported from this tornado. EPISODE NARRATIVE: A warm front retreating to the north and a cold front approaching from the west produced strong to severe thunderstorms across New Jersey during the afternoon and early evening of the 29th. One EF-2 tornado also occurred. The wind damage and lightning resulted in about 57,000 homes and businesses in losing power. | |||||||||||

| Brief Description: The cell that produced tornadic damage earlier both in southern Wayne county and just upstream in Promised Land State Park dropped a tornado once again across the southern and southeastern portions of Pike county. A nearly continuous 20 mile path was uncovered via aerial storm surveys from Pecks Pond east-southeastward to near route 739 in Delaware township. The average width of the damage path was about 200 yards. The twister descended once again in the Pecks Pond area around 8:20 pm EDT. At that point, the intensity was rated as F2 as the tornado cut down nearly every tree in its path on its way towards Blue Heron Lake. At approximately 8:30 pm, the tornado struck the small vacation community surrounding Blue Heron Lake. A summer home was leveled by the force of the twister. The only things left standing were an interior wall and a few sturdy metal cabinets on the floor in the kitchen. An adjacent mobile home was severely damaged as well. Two campers near this area had minor injuries from falling tree limbs. Otherwise, though, injuries were kept to a minimum as homes were mostly vacant. In addition, an estimated thousands of trees were sheared off or toppled bordering Blue Heron Lake both to the west and east. The twister's intensity increased at this point to F3. Further downstream, the tornado continued to cut a consistent path of twisted off and/or uprooted trees across the Little Mud Pond, Silver Lake, and Deer Leap Factory areas. The tornado appeared to skip across hilltop sections along this route with its intensity mainly in the F1 range. Finally, just before 8:45 pm EDT, the tornado ascended once again in Delaware township as little in the way of damage was evident between route 739 and the Delaware River. In all, emergency management and federal officials estimated that in excess of 1 million dollars damage was incurred along this approximately 20 mile path. Many roads were closed as they became impassable due to fallen trees and wires. Portions of routes 402 and 390 were closed for several days. In addition, sections of Promised Land State Park were closed off to the public for about two weeks until all debris was cleared away and power was restored. An intensifying storm system moved across upstate New York and into southern Quebec early in the morning on the 31st. This system dragged a warm front across northeastern Pennsylvania. Behind this front, a southerly flow of warm, moist, and unstable air quickly developed. This set the stage for the development of severe weather later that afternoon as a cold front and strong upper air disturbance approached. From late in the afternoon until late that evening, northeastern Pennsylvania was under siege from severe thunderstorms, including several tornadic supercells. In all, nine separate tornadoes touched down on this day. Overall damage estimates run into the millions with many homes and structures heavily damaged or destroyed. The most devastating storms occurred in Pike county. Within about a 3 hour stretch from 7 to 10 pm EDT, four different twisters affected the county. One tornadic cell was responsible for knocking down thousands of healthy large trees in and around Promised Land State Park with several vacation homes damaged or leveled. Fortunately, injuries were kept at a minimum. Widespread straight line wind damage also occurred with hailstones the size of ping pong balls falling in some places. The north side of Scranton had extensive wind damage as a storm passed through shortly before 10 pm EDT and sections of Wayne and Luzerne counties had roads closed and/or blocked from falling trees for more than 2 days after the storm. Pennsylvania Power and Light Company estimated that hundreds of thousands of customers were without power at the height of the storms on the evening of the 31st. Some of the more remote locations did not have power restored for the better part of a week. | |||||||||||
