List of Pennsylvania hurricanes

As of 2021 Pennsylvania has been affected by approximately 53 tropical storms and hurricanes, some with winds reaching as high as {{convert|75|mph|km/h}}. The state is landlocked in the Northeastern United States. No storm has ever made landfall in the state, though many storms, notably Hurricane Irene and Hurricane Ida, have passed through the state as an extratropical cyclone. A notable one of these storms was Hurricane Agnes in 1972, with 50 people dying due to the storm in Pennsylvania.{{Cite web |last=US Department of Commerce |first=NOAA |title=Hurricane Agnes |url=https://www.weather.gov/ctp/Agnes |access-date=2024-10-28 |website=www.weather.gov |language=EN-US}} The strongest winds in the state were from Hurricane Sandy. Winds of {{Convert|81|mph|km/h}} were recorded in Allentown, Pennsylvania.{{Cite web |last=Wesser |first=James |title=What are the strongest wind gusts in Pennsylvania? |url=https://www.abc27.com/pennsylvania/what-are-pennsylvanias-strongest-wind-gusts/ |access-date=2024-10-28 |website=www.abc27.com}} While it is very uncommon for a system to hit Pennsylvania while tropical, many systems see their remnants pass through the state.
