| 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: 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: An F2 (on the Fujita scale) tornado touched down in northern New Castle County with maximum winds estimated at 130 mph. The path length was 5.0 miles long with a maximum path width of 150 yards. The tornado touched down near and was observed at the New Castle County Airport. The northern end of the tornado track was in Elsmere. Significant damage did occur along the path of this tornado, particularly to some of the planes at the airport and industrial buildings near the airport. In addition, five persons were injured. The tornado damaged five C-130 cargo planes at the New Castle County Airport, caused thousands of pounds of jet fuel to spill and damaged hangers. It tore through the Newport Industrial Park along Delaware State Route 141. It tossed long strips of metal siding into the air and onto roads. Windows were shattered, walls peeled away and trees and light poles were snapped. The roof and whole side of the United Electric Supply building was torn away. Delaware State Route 141 and some nearby side streets were closed. Gas service was shut off to prevent explosions. On Bellecor Drive, a self-storage facility suffered major damage. One man at the business was injured after he was trapped under a fallen refrigerator. Three people were injured at the airport itself. A man in Elsmere was hit by a fallen tree limb. The tornado also caused damaged to homes in Wilmington Manor and Chelsea Estates near the airport. In Elsmere, the tornado tore shingles and vent covers from the Corpus Christi Elementary School. The ensuing heavy rain damaged the gymnasium. In the Red Clay Consolidated School District, the tornado also caused minor damage to the Richardson Park Elementary School. | |||||||||||
