A storm survey team consisting of meteorologists from the National Weather Service and staff from the Westchester Office of Emergency Management conducted a ground and aerial survey of wind damage from thunderstorms on Friday July 29th. Based on information gathered during the survey and conversations with local residences, the damage is being attributed to a microburst. The microburst had estimated maximum gusts of 80 mph associated with it, a path length of about 1.4 miles, and a maximum path width of 0.4 miles.||Damage from this microburst began on the Croton River along Route 9 and spread south-southeast towards central Ossining. The damage consisted primarily of snapped trees. A large 3-4 foot diameter tree fell on Route 9 near Eagle Bay Drive taking down power lines that resulted in the snapping of several telephone poles. Significant tree damage occurred at Cedar Lane Terrace at 6 Meadowbrook Drive. The tree damage was noted in a divergent pattern.

A large tree and power lines were reported down on Anderson Hill Road in Purchase.

A powerful cold front produced numerous severe thunderstorms across Connecticut, Long Island and the Lower Hudson Valley of New York. Some of the storms were very heavy rain producers, training across the same area, which caused isolated flash flooding on Long Island.

As a strong cold front moved east, a wave of low pressure rapidly intensified as it moved northeast along the front. A line of severe thunderstorms developed and moved southeast across the region. This line enhanced the strong synoptic scale wind gradient in place and produced damaging winds. High winds downed trees and power lines in Port Jervis and Monroe in Orange County and in Ossining in Westchester County.

Remnants of Tropical Storm Ernesto brought heavy rain and gusty winds of 40 TO 57 MPH across Long Island and Southeast New York, east of the Hudson River, including most of New York City. This resulted in numerous trees and power lines down with hundreds of thousands of power outages reported.

A cluster of severe thunderstorms moved east across the Lower Hudson Valley. High winds downed trees and power lines.

Severe thunderstorms produced damaging winds and large hail across many locations. High winds downed many whole trees, large tree branches, and power lines. News radio WCBS reported up to 150,000 power outages across the tri-state region.The National Weather Service confirmed that as a severe thunderstorm moved northeast, it produced a down burst near White Plains around 10:45 pm EDT. Wind damage to trees was observed from near the Scarsdale-White Plains border east through Harrison to Port Chester. Most of the wind damage in these towns was to trees, with many of them uprooted and all falling in the same direction, east to northeast (ENE). This damage was caused by 50 to 60 mph straight line winds. An embedded area of higher straight line winds occurred near the White Plains-Harrison border, the region bounded by the Maple Moor Golf Course to the east, Ridgeway Country Club to the west, and Interstate 287 to the north. Many large trees were downed in this area, some at least 3 feet in diameter. A few trees fell on houses and cars. The trees fell all in the same direction, east to northeast (ENE). The highest wind gusts were estimated up to 75 mph.

A line of thunderstorms formed ahead of an advancing cold front. The airmass ahead of the front was moist and unstable. As the thunderstorms moved into the Lower Hudson Valley, they became severe and knocked down several trees which caused power outages.

A strong cold front moved into a very unstable airmass over the Lower Hudson Valley of New York. A line of thunderstorms formed along the cold front, some of which produced wind damage such as knocking over large trees and downing power lines. Frequent lightning occurred as well.

On Friday, August 10th, a strong cold front moved east across southeast New York during the afternoon hours, preceded and accompanied by several lines of strong to severe thunderstorms. The cold front, which separated oppressively hot and humid air from significantly cooler and drier air, combined with very unstable atmospheric conditions to produce rapid and intense thunderstorm development during the early afternoon hours. Strong wind gusts accompanied the thunderstorms, tearing trees down, which subsequently fell onto power lines and led to numerous power outages. Nearly 90,000 customers were affected by the power outages on Long Island. Fallen trees and large tree limbs blocked several roadways, and led to scattered road closures. In Westchester County, numerous large tree limbs were downed in the vicinity of Armonk and North Castle. In Nassau County, numerous tree limbs were also downed near Roslyn. In Suffolk County, several tree limbs were downed in the vicinity of Hauppauge and also in Southampton. Heavy rainfall and frequent cloud to ground lightning also accompanied the thunderstorms. The heavy rainfall fell in excess of one inch per hour, leading to highly localized flooding of roadways and highways. Frequent cloud to ground lightning struck many buildings and electric poles, producing additional power outages.

During the morning hours of Wednesday, July 11th, a strong cold front swept across southeast New York. As this front clashed with moist and unstable air already in place, a line of strong to severe thunderstorms rapidly moved east-southeast across portions of southeast New York and Long Island. The line eventually developed into a "bow-echo" structure, which produced a swath of damaging winds and dime size hail across portions of Westchester County in southeast New York and Suffolk County on Long Island. Wind gusts were measured at 61 mph as the line passed through Stony Brook. These damaging winds toppled numerous large trees onto power lines and roadways, which resulted in scattered power outages and road closures. There were numerous reports of dime size hail, including at the National Weather Service Office in Upton.

With a warm humid unstable air mass in place, lines and clusters of scattered severe thunderstorms developed ahead of a cold front that moved slowly southeast. As severe thunderstorms moved east at 15 to 20 mph, they produced high winds that downed trees and power lines in the Rio/Deer Park area of Orange County, in Brewster and in Somers, where golf ball sized hail was also observed.

A low pressure system rapidly intensified as it moved northeast across the Great Lakes as a strong high pressure system northeast of New England moved slowly northeast during Sunday, December 17th. The difference in pressure between these systems caused increasing south winds. As an intensifying cold front trailing from the low approached the area with abundant low level moisture in place, widespread rain with embedded thunderstorms occurred. Heavy rain caused significant flooding in Orange and Rockland Counties. It also caused localized flooding of low-lying and poor drainage areas. Heavy showers, some associated with severe thunderstorms, produced wind damage at several locations.Here are selected wind damage reports and measured peak wind gusts:In Putnam County, high winds downed several trees and power lines throughout the county. Large trees fell across Route 6N in Mahopac Falls, which caused a partial road closure.In Rockland County, high winds downed trees and power lines at several locations.In Westchester County, high winds downed trees and power lines at several locations including Sleepy Hollow, Ossining, Rye, Yorktown, and Lewisboro.In Queens County, high winds downed trees onto buildings and lifted sidewalks as they uprooted.

The second band of heavy rain extended from Eastern New Jersey northeast across Western Rockland County, where 2 to 2 1/2 inches of rain fell with isolated amounts up to 3 inches. Widespread flash flooding of low lying and poor drainage areas occurred at several locations throughout Orange County. Both small stream and urban flooding occurred across Western Rockland County.Here are selected rainfall amounts and flood damage reports:In Orange County, rainfall amounts from available locations ranged from 2.11 inches at Gardnerville to 2.80 inches at Sterling Forest.
