(22nd-24th) George Washington Hurricane; After causing ship disasters off SW Bermuda, the storm moved NW over Tidewater, NC and VA to pass right over George Washington's Mt. Vernon plantation. On July 24th, George Washington wrote in his diary: "About noon the wind suddenly shifted from NE to SW and blew the remaining part of the day violently from that quarter. The tide this time rose near higher than it was ever known to do, driving boats, etc. into fields, where no tide had ever been heard of before, and most, it is apprehended, having done infinite damage on their wharves at Alexandria, Norfolk, Baltimore, etc. At home all day."
