NOAA recorded where this tornado touched down but not where it lifted, so it appears as a point. Other tornadoes recorded nearby that day are shown faint.

What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

The National Weather Service confirmed a brief tornado from an eyewitness report of about 15 trees with their tops torn off in a forested area on a hilltop at about 2400 feet elevation. This report aligned with strong rotation evident on Doppler radar imagery. The maximum estimated winds were 90 miles per hour.

The wider storm

Severe thunderstorms developed along a warm front during the afternoon of the 27th. Two of these storms became quite intense as they tracked from the northern Catskills through the Mid-Hudson Valley and into the Taconics. These storms spawned a brief tornado in a forested area in Greene County, and produced more widespread wind damage in the Amenia, Dover Plains, and Millbrook regions of Dutchess County with numerous downed trees. One fatality occurred in East Fishkill as a tree was downed onto a moving vehicle. More than 4,000 people in Dutchess County and 2,000 people in Ulster County lost power as a result of the storms. The storms also produced a couple of reports of hail up to half dollar size.

Began near Halcott Center (42.2162, -74.5152).
