The 1933 Chesapeake–Potomac hurricane was among the most damaging hurricanes in the Mid-Atlantic states in the eastern United States. The sixth storm and third hurricane of the very active 1933 Atlantic hurricane season, it formed in the eastern Atlantic, where it moved west-northwestward and eventually became a Category 4 on the Saffir-Simpson hurricane wind scale. A strong ridge over New England allowed a continued northwest course, bringing the storm south of Bermuda and later toward the middle coast of the eastern United States. Advance warning allowed hundreds of people to evacuate ahead of the hurricane making landfall. It did so in northeastern North Carolina on August 23 with winds of about 90 mph (150 km/h). Soon after, the eye crossed over Norfolk, Virginia, the first time that happened since 1821. The hurricane weakened into a tropical storm over northern Virginia shortly before passing near Washington, D.C., becoming the worst tropical cyclone there since 1896. Curving northward, the storm moved through Pennsylvania and New York before losing tropical characteristics on August 25. Now extratropical, the former hurricane moved across Atlantic Canada, dissipating on August 28.

Across the eastern United States, the hurricane left widespread damage amounting to over $40 million (equivalent to about $800 million in 2020) and causing at least 47 deaths. Although the storm struck North Carolina, damage in the state totaled only about $250,000, largely to crops and transport. Along the Chesapeake Bay, the storm produced 100-year flooding from its storm surge, setting records that remained for 70 years. In Virginia, flooding covered downtown portions of Norfolk in the southeast and Alexandria in the north. Damage in the state was estimated at $17.5 million. Similarly heavy damage occurred in Maryland, including over $7 million to crops. High waves along the coast eroded beaches and created a new inlet at Ocean City. The highest rainfall associated with the hurricane was 13.28 in (337 mm) at York, Pennsylvania. In the state, the rains flooded several rivers which forced thousands to evacuate. In neighboring New Jersey, high waves wrecked boats and destroyed a fishing pier, while in New York, flooding caused traffic jams. In Atlantic Canada, heavy rainfall assisted firefighters in combating wildfires, and the associated winds caused isolated power outages.

Vintage photos: the 1933 Chesapeake Potomac hurricane – flooding in Washington, D.C.

Eighty years ago today, the Chesapeake Potomac hurricane pushed a wall of water up the Potomac River and Chesapeake Bay. It also carved the inlet between Ocean City and Assateague Island, as Don Lipman described in his earlier post.

The incredible 11-12 foot storm surge that rushed up the Potomac river caused massive flooding in tidal areas of Alexandria and the District.

On the Library of Congress’ Web site, CWG’s Kevin Ambrose discovered a set of archived photos documenting both the surge and stream flooding around the District.

I reproduce them here:

1. My mom remembered this well, she grew up on the Eastern shore of Virginia

The storm wiped out all the development on the bay side of the peninsula. There was no building back of it for decades and decades
