| 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.

| 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: 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. | |||||||||||
