| 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: A strong cold front crossed eastern New York late on May 18. At the same time, very strong winds aloft moved over the area. The combination of the instability, and lift ahead of the front, spawned a line of thunderstorms. These storm tapped into the strong wind aloft, to produce the largest outbreak of severe weather across eastern New York in nearly two years. While the vast majority of damage was from thunderstorm winds, there was also some hail damage reported, along with two confirmed tornadoes. It was the first time since June 1998 that a tornado was officially confirmed in eastern New York. Thunderstorm winds knocked down large trees a powerlines at several locations in Albany, Columbia, Greene, Montgomery, Saratoga, Schoharie and Ulster counties. Dutchess county was especially hard hit. A line of strong to locally severe thunderstorms first moved into Montgomery County during the mid afternoon. Strong winds blew down large trees in Fort Plain. Then a microburst produced a swath of damage, 8 miles long, from west to east in the town of Canajoharie. The swath began at the intersection of Nestle and Clinton roads where a large barn lost its roof and two sides. Debris was blown over the adjoining house, landing inside a garage on the other side of the intersection, as well as up the road about 40 feet . A wooden silo located adjacent to the garage lost one entire side, thus collapsing inward inside the silo. The rest of the damage was mainly from snapped power poles and trees, as the path ended just west of Knauderack Creek, adjacent to Bower road. Trees and powerlines came down in Selkirk, Albany county, as well as Gilboa and Jefferson in Schoharie county. At Ballston Lake, in Saratoga county, a microburst sheared off 8 forty-foot trees at the 10 to 20 foot level. One tree damaged a house. More trees and limbs fell in Clifton Park. Another series of microbursts began in Ulster county about a mile northwest of the center of Esopus. They knocked down several clusters of trees as they neared State HIghway Route 9W, while moving in an easterly direction. Embedded within the microburst, an F1 tornado, touched down briefly to the east of Black Creek and 9W, less than a tenth of a mile south of the center of Esopus. The track of the tornado was about a quarter mile long and 25 to 50 yards wide with numerous trees pushed about 70 degrees to the left of the storm track. There was little property damage due to the tornado, but it was sighted by nearby residents. Meanwhile the series of microbursts continued across the Hudson river, into Dutchess county, blowing over over the estreme southern portion of Hydeo Park as well as the Poughkeepsie Yacht club in northern Poughkeepsie. Winds were clocked at 126 mph at the Poughkeepsie Yacht club. Several boats were overturned and damaged. A trailer was overturned. The roof was removed from the Yacht club. Damage from this microburst fanned out to a width of approximately one hundred yards, and a path length of up to a quarter of a mile. The wind overturned a car. The roof was removed from the Yacht club. Damage from this microburst fanned out to a width of approximatley 100 yards, and a path length of up to a quarter of a mile. A car was damaged by a falling tree in Hyde Park. A weaker F0 tornado, touched down in the Fairview section of the town of Poughkeepsie, about one quarter mile east of the Fairview Fire Station, on the leading edge of another microburst. The width was 25 yards, the length less than one hundred yards. Damage from the tornado was marginal, confined to downed trees and some minor structural damage to seven homes. Thunderstorm winds produced damage in many other portions of Dutchess county. Another microburst produced damage between County Route 83, just north of U.S. Highway Route 44, east to the village of Leedsville. Damage included destruction to a barn on the Bel Air farm. Many trees were down in a huge swath with this microburst. There were unconfirmed sightings of funnel clouds in this area. Many trees fell in Millbrook, which was described as a war zone. Large trees were uprooted in Clinton Corners and falling trees knocked powerlines down in Rhinebeck. In Pawling, a large tree fell on power lines, then crashed onto a car, causing extensive damage. Trees were blown across a power line, which then fell on Allyn's restaurant in the Town of Washington. Trees and poles were also blown down in the village of Fishkill. Winds were clocked to 70 mph in Stone Ridge, and 60 mph at New Paltz, both in Ulster county. Many windows were smashed or blown out of buildings at the New Paltz S.U.N.Y. campus. Trees were blown over in Ellenville. A tree fell on the mayor's car in that town, destroying it. Another tree damaged a historical home. A 60 mph wind gust was also recoreded at Kinderhook, Columbia county. Two 50-foot concrete silos of a coach barn in Gallatin, Columbia county were obliterated. A door was blown off a nearby house. In the promixity of Gallatin, a car was destroyed by a fallen tree. Huge trees fell on Schneider road in Columbia county. Many trees were snapped off their bases in East Taghkanic. Shingles from a roof were blown off in Cairo, Greene county and large trees fell on a house in and around the town of Phoenicia. A microburst uprooted many 22 to 24 inch diameter trees and snapped utility lines in the vicinity of Route 23, a few hundred yards north of the intersection of County Route 23A. Dime size hail fell at Kerhonkson, Ulster county. Pea-size hail was noted at Tivoli and Clinton corners, both located in Dutchess county. While property damage with the hail was minimized, hail took a toll on apple orchards. Many apples were partially damaged by small hail in Ulster and Dutchess counties that produced permanent indentations on the apples, making them unusable for sale. Total crop damage could easily exceed a million dollars. Lightning took the life of two horses at a farm in Ballston Lake. At the height of the storms, up to 52,000 customers, mainly in the Mid Hudson Valley region, were without power. A funnel cloud was noted by two on-duty meteorologists at the National Weather Service office at Albany. There were no human injuries or casualties, reported to the National Weather Service, in association with this large severe outbreak. | |||||||||||

| 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: The NWS confirmed that an F2 tornado was responsible for significant damage that occurred in Lynbrook. Most of the village received damage from straight line winds up to 80 mph, that was associated with a severe squall line. Downed trees covered the village with some structural damage where the F2 tornado touched down. The major path of damage was from the northwest section of Lynbrook east-southeast to the southeast section of the village. Funnel clouds were observed from near the intersection of Marshall Ave. and Burtis Street and to the southeast. A tornado was first sighted by two eyewitnesses on Hampton Place. It rose and touched down several times: Second, near Winter Street and across Glover Circle; Third, along Peninsula Blvd. between Earle and Benton Avenues; and Fourth, as a weak F2 near the intersection of Rocklyn Ave. and Merrick Road. It moved across the Long Island Railroad Tracks and Sunrise Highway before it finally dissipated. More than three hundred trees were blown over, many on houses and cars. Six people received minor injuries. Four of these were in "The Fun Zone" on Rocklyn Avenue. One woman was slightly injured by a tree that fell on her car. One police officer was also injured. An intense line of severe thunderstorms oriented from north to south developed during Labor Day afternoon ahead of a strong approaching cold front. As the storms moved east at 40 to 50 mph, they produced high winds, large hail, and an isolated tornado. Wind gusts from 60 to 80 mph downed many trees and power lines throughout the area. The cost estimates of damage included above are preliminary figures submitted by the Nassau County Office of Emergency Management. In Richmond County, the following peak wind gusts were reported: 80 mph at Great Kills, the Verranzano Bridge, and in Richmond. High winds downed trees and caused a building to collapse in Richmond. One tree fell on and injured a man in Richmond. In New York County (Manhattan), high winds caused a building to collapse.
