A line of thunderstorms developed to the north of the Mohawk Valley last Wednesday afternoon (October 7th) and strengthened as it moved south through the Mohawk Valley. There were numerous reports of damaging winds, small hail and even a brief tornado touchdown in Canajoharie. The storms traveled over 300 miles making it all the way to Cape Cod. The National Weather Service confirmed this was a derecho.
You may have heard of a derecho before as Central New York will typically see a derecho once every three or four years. A derecho is defined as a long-lived line of damaging thunderstorms. The swath of wind damage (58+ mph gusts) must extend over 240 miles in order to be classified a derecho. This derecho strengthened as it moved to the east of the Mohawk Valley putting hundreds of thousands in the dark in the Capital Region along with producing up to 75mph wind gusts.
