1933 Chesapeake–Potomac hurricane

[nb 1] 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.

Although the storm struck North Carolina, damage in the state totaled only about $250,000,[nb 2] largely to crops and transport.

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.

On August 13, a tropical depression developed near the west coast of Africa, southeast of Cape Verde, with an associated closed circulation.

Based on observations from a nearby ship, it is estimated the depression quickly intensified into a tropical storm while moving generally to the west-northwest.

Based on interpolation of reports, it is estimated the storm intensified into a hurricane on August 16 while halfway between Africa and the Lesser Antilles.

[5] After remaining near peak intensity for three days, the hurricane began steadily weakening while curving more to the west-northwest,[5] a rare track for the region due to steering from a ridge over New England.

At 1000 UTC on August 23, the hurricane made landfall along the northern Outer Banks of North Carolina,[5] near Nags Head,[1] with a pressure of 963 mbar (28.4 inHg).

Based on the steady weakening, coastal observations, and a larger than normal size, landfall winds were estimated at 90 mph (140 km/h).

A few hours later, the hurricane made another landfall on the North Carolina mainland after crossing the Albemarle Sound.

[8] Early on August 21, the Weather Bureau issued storm warnings from Cape Hatteras to Boston, Massachusetts.

[7] The Federal Emergency Management Agency later used high water levels from the storm as a 100-year event for the Chesapeake Bay region.

[12] This hurricane caused damage from North Carolina through New Jersey, due to the combination of high winds and storm tides,[6] and left at least 47 people dead overall.

Across the region, the storm downed power lines, washed out highways, wrecked boats, and destroyed houses, and overall damage in the state was around $250,000.

In Hampton the storm surge flooded Langley Air Force Base, swamped homes and businesses, wrecked boats, and destroyed fishing piers.

[1] In Virginia Beach, the storm knocked down about 600 trees, many of them about 100 years old, and over 79,000 people lost telephone service.

[6] However, high waves damaged the steamer Madison with 90 people on board and caused it to drift off Cape Charles, which necessitated rescue from the Coast Guard.

[10] Inland flooding occurred along the James River as far west as Richmond, where damage was limited to downed trees and broken windows.

The pier of the Jamestown Ferry was washed out in Surry and a marina at Jordan Point near Hopewell was wrecked after the river reached the highest level on record.

At Colonial Beach along the Potomac River, the surge flooded the town with 4 ft (1.2 m) of water and wrecked a local amusement park.

High winds in the city caused power outages, and flooding along the Cameron Run washed out a bridge.

The combination of rain and winds damaged crops in Fairfax and Loudoun counties, mainly to corn and peaches.

In Washington, D.C., the storm dropped 6.39 in (162 mm) of rainfall, at the time the highest on record for a single day total.

[16] Heavy rainfall in the state increased water levels along streams, causing one person to drown at Mount Tremper.
