Survey Summary:
The National Weather Service in Buffalo completed a damage survey
across Niagara County today in response to reports of 
concentrated areas of damage near Olcott from a line of severe 
thunderstorms yesterday, September 2nd.

A severe supercell thunderstorm, that had been previously sighted
having a waterspout, moved onshore over Olcott in northern 
Niagara County shortly after 6 pm. It is unclear based on the 
shoreline damage if the waterspout moved onshore, but about one 
block inland along Main Street, significant tree damage was 
observed and this is where we are confident the tornado started. 
The tornado then continued south-southeastward crossing the Great 
Lakes Seaway Trail and entered the southern portion of Krull Park 
while also producing tree damage along Althea Street. Drone video 
obtained by Niagara County Emergency Services indicated large 
swirls in the open grass south of the entrance, which led to the 
most significant tree damage where a whole stand of mature pine 
trees were snapped and uprooted. The tornado then weakened 
southeast of here with sporadic tree damage observed and likely 
lifted just east of the park.

The National Weather Service extends its thanks to Niagara County
Emergency Services for their assistance with todays survey.

Survey Summary:
The National Weather Service in Buffalo investigated storm-
related damage from a bowing line of thunderstorms that ended up
producing an EF-1 tornado during the evening of September 2nd that
affected areas east of Alexander, NY near Route 20. 

Initial damage from the tornado was noted in a corn field north 
of Route 20 both north and south of Browns Mill Road. Downed corn
crops displayed a convergent pattern with an initial path width 
paced at 70 yards. Nearby, additional tree damage was observed 
with multiple tree branches broken and one large tree trunk 
snapped. The damage path continued southeast toward W Bethany Road
where broken tree branches and additional convergent signatures 
within a corn field were observed both east and west of the 
roadway immediately north of Route 20. In the distance, uprooted 
and leaning trees with branches broken were observed along the 
same path south of Route 20. 

Farther to the southeast, the survey team found similar tree 
damage along Silver Road and Mill Road. A higher density of downed
and snapped trees were observed near a residence along Mill Road.
This included a dense cluster of large locust tree trunks snapped
with a convergent pattern that led to the high-end EF-1 rating 
for this tornado. Sporadic tree damage continued near Linden and 
along Skates Hill Road just north of the Genesee-Wyoming County 
Line.

across Orleans County today in response to reports of 
concentrated areas of damage near Shelby from a line of severe 
thunderstorms yesterday, September 2nd.

A severe supercell thunderstorm moved into western Orleans county
shortly after 6:30 pm passing just south of Medina. As it moved 
over East Shelby the low level circulation tightened and a tornado
touched down in a field east of Bigford Road and south of Martin 
Road. Several trees were toppled on the edges of this field before
the tornado crossed over East Shelby Road causing significant 
tree damage across several residences on the east side of the 
road, along with minor structural damage to a home. The tornado 
then continued eastward through a forested area with numerous 
trees uprooted and few snapped. The tornado then lifted over an 
open field west of Townline Road.

The National Weather Service extends its thanks to Orleans County
Emergency Management for their assistance with today's survey.

Survey Summary:
The National Weather Service in Buffalo completed a damage survey
across southeast Wyoming County today in response to reports of 
concentrated areas of damage near Portageville and the southern 
end of Letchworth State Park from thunderstorms on the evening of 
September 2nd. A line of severe thunderstorms moved through the 
area during the evening hours, producing areas of thunderstorm 
wind damage. Several small, brief areas of rotation developed 
along the line and produced this brief squall line tornado around 
8 PM EDT.

The first instance of damage was noted along Griffith Rd just 
east of Halvorsen Rd in the Town of Genesee Falls, about one mile 
west of Portageville. Sporadic tree damage was noted in this area.
Sporadic tree damage was also noted along the eastern end of East
Koy Rd, which was likely a mix of thunderstorm wind damage and 
tornado damage. Tree damage became more significant at the eastern
end of Griffith Rd near the intersection with Route 19A, where 
dozens of healthy hardwood and softwood trees were uprooted or 
snapped off at the trunk. The tree damage in this area showed a 
distinct convergent pattern. Significant tree damage extended east
across Route 19A into Letchworth State Park near the Portageville
entrance, with numerous large trees uprooted or snapped off at 
the trunk on the slope between Park Rd and the Genesee River. The 
damage then rapidly diminished along the Genesee River, at which 
point the brief tornado dissipated just north of the Hamlet of 
Portageville.

This tornado was in close proximity to another tornado just over 
the Genesee River in Livingston County. Radar data and the damage 
paths suggest these were two separate, distinct tornado damage 
paths with a different path orientation.

The National Weather Service extends its thanks to Wyoming County
Emergency Management for providing the location of the most 
significant damage.

Survey Summary:
The National Weather Service in Buffalo completed a damage survey
across southwest Livingston County today in response to reports 
of concentrated areas of damage near Portageville and the southern
end of Letchworth State Park from thunderstorms on the evening of
September 2nd. A line of severe thunderstorms moved through the 
area during the evening hours, producing areas of thunderstorm 
wind damage. Several small, brief areas of rotation developed 
along the line and produced this brief squall line tornado around 
8 PM EDT.

The first instance of damage was on the eastern side of the gorge
in Letchworth State Park along the East Parade Grounds Rd in the 
Town of Portage. There was significant tree damage in this area, 
with dozens of large hardwoods snapped and uprooted. A cluster of 
a half dozen large and very tall locust trees were snapped off at 
the trunk, with several falling on a large park pavilion. The 
structure sustained significant damage from the falling trees. 
Farther southeast along East Parade Grounds Rd, several dozen 
hardwood and softwood trees were uprooted or snapped, with tree 
damage in this area showing a convergent path. The final damage 
location was along River Rd just northeast of Route 436, with 
another cluster of a dozen hardwood trees uprooted or snapped at 
the trunk. Tree damage in this area showed a clearly convergent 
and rotational damage path. The path of damage ended in a forested
area just north of Route 436.

This tornado was in close proximity to another tornado just over 
the Genesee River in Wyoming County. Radar data and the damage 
paths suggest these were two separate, distinct tornado damage 
paths with a different path orientation.

The National Weather Service extends its thanks to Livingston 
County Emergency Management for providing the location of the most
significant damage, and for providing an escort through the 
heavily damaged east side of Letchworth State Park.

Survey Summary:
The National Weather Service in Buffalo completed a damage survey
across eastern Monroe County and western Wayne County today in 
response to reports of concentrated areas of damage near Webster 
and Ontario from a line of severe thunderstorms on Wednesday, 
September 2nd.

Embedded low level rotation within a squall line moved through 
Webster shortly before 7:30 pm, and a tornado touched down in the 
vicinity of Salt Road just north of Route 104 as evidenced by 
several snapped softwood trees. The tornado then crossed Route 104
as it headed southeastward, with another area of concentrated 
damage noted near the intersection of Basket Road and Ridge Road. 
Here several hardwood trees were snapped or uprooted, and a few 
power poles were knocked down. The tornado then continued to the 
southeast through open fields until encountering a small 
subdivision just west of County Line Road. Here the most 
significant damage occurred with roof uplift, considerable shingle
loss, and siding damage on a few homes on Halesworth Lane and 
Bannerwood Drive. Numerous trees in the subdivision were also 
snapped or uprooted. Additional tree damage was seen along 
Foxworth Drive, and then the tornado traveled through a large 
forested area with no road access. Finally, the tornado emerged 
along North Lincoln Road just north of Whitney Drive, and produced
extensive tree damage at a large property where numerous mature 
trees were uprooted or snapped, before lifting just east of this 
area.
