Episode Narrative	A cluster of heavy thunderstorms produced torrential rain that resulted in widespread and significant flash flooding across the region. Maximum 1 hour rainfall rates were estimated at 2 to 3 inches. The storm total rainfall for this event ranged from around 3 to 6 inches. Nassau Community College measured 5.18 inches. Other amounts included 4.20 inches in Holtsville and 3.35 inches in Fresh Meadows. Thunderstorms produced many frequent and intense lightning strikes that resulted in more than 20,000 customers without power across portions of Long Island, as reported by the Long Island Power Authority. A severe thunderstorm produced an EF1 tornado in East Islip Terrace.
Event Narrative	National Weather Service Meteorologists investigated storm damage in the Islip Terrace area and confirmed that tornadic damage occurred. The tornado touched down in the town of Islip Terrace near the intersection of Irish Lane and the north service road of Sunrise Highway. It moved east to northeast across Carleton Avenue, Roslyn, and Nassau Streets, and lifted near Nassau and Kunigunda Place. The path was discontinuous over two thirds of a mile. The width was narrow at first, only around 50 yards near the intersection of Irish Lane and the north servicee road of Sunrise Higyway, then fanned out to 150 yards further east. Most of the damage was to hard wood trees. Twisted off branches were evident throughout the damage path. Some trees were snapped off half way up, including some healthy 40 foot pines. The Medical Arts Building at Irish Lane and Sunrise Highway sustained structural damage, with a significant loss of its' roof covering and the HVAC unit blown off its roof. Other homes along the damage path also sustained minor damagee to siding and some directly from fallen trees.
