Late Twentieth Century Hurricanes in Virginia

Comment: Virginia is considering uranium mining all over the state! We have earthquakes but we have many Hurricanes, which causes flooding! The anniversary of Hurricane Camille is Thursday, so this blog will highlight the hurricanes of the 20th and 21st century and the affects it will have on uranium mining which is flooding! Many people will remember Hurricane Hazel, she brought destruction to Halifax and Pittsylvania County!

August 13, 1953 (Barbara): Early on the 11th, a tropical storm was discovered in the southeastern Bahamas. It became a hurricane northeast of the Bahamas on the 11th and gained intensity as it moved north. At 10 p.m. on the 13th, it struck the North Carolina coast between Morehead City and Ocracoke (track to the right). The storm then moved north and northeast, before going out to sea just south of Norfolk. Winds reached 63 mph with gusts to 76 mph at Norfolk. Winds at Cape Henry were sustained at 72 mph. Cape Henry lighthouse saw its copper canopy torn loose during the cyclone. Rainfall amounts of five to eight inches were common across southeast Virginia. Portsmouth saw 9.3" of rain deluge the city in only 24 hours.

August 25-31, 1954 (Carol): Hurricane Carol, a major hurricane when it made landfall in North Carolina, moved northward into New England (track above and below). It moved 100 miles off the Virginia Capes and brought winds of 40 mph to Virginia Beach. Norfolk received four inches of rain. Chincoteague reported the lowest pressure...29.28". The system helped ease drought conditions in Washington, D.C..

October 15, 1954 (Hazel): On the 4th, a tropical storm moved through the Windward Islands into the Caribbean Sea. It quickly formed into a hurricane and continued on a westerly track until the 10th. An upper low in the western Caribbean steered Hazel northward through the Mona Passage on the 12th. As the hurricane did so, heavy rains caused mudslides in Haiti which killed 500 people. Its track became northwesterly as a cold front approached from the Mississippi Valley. The hurricane then accelerated into northeast South Carolina as a category four hurricane. On the 15th, it passed over Raleigh, Richmond, and West Virginia (track to the left). One of the most severe storms to ever strike the Eastern seaboard caused destruction at beach resorts. Pressures fell to 28.67" at Virginia Beach, 28.75" at Richmond, and 28.99" at Norfolk. Trees, power lines, and radio towers were downed. Power failure was common across the region...in some areas, for as long as 48 hours

Considerable damage was done to residential and business property in Washington as sustained winds peaked at 78 mph with gusts to 98 mph. At National Airport, a light plane flipped over and part of the hangar was blown away. The Weather Bureau radar had to be turned off for three hours when the motor began to heat up. As a cold front interacted with Hazel, a squall line swept through Washington, D.C. at 6:15 p.m., dropping the temperature 20 degrees in one hour. Frost was seen in the suburbs the following night.

Hundreds of trees fell across the Federal City. Many store front windows shattered. Falling trees damaged many houses in Fairfax. Winds whipped up white caps on the Potomac. Waters overflowed the seawall at Hains Point. Alexandria saw the Potomac flood reclaim two blocks of the city, flooding basements and first floors of businesses. U.S. 1 was flooding by 9 p.m. at Hunting Creek. Heavy rains fell in the mountains, with a couple locations measuring over 10 inches.

Norfolk's sustained winds reached at 78 mph with gusts to 100 mph. Hampton saw winds as high as 130 mph. Damage was extensive from strong winds and high tides. Several ships in the James River were sunk or wrecked. At the Old Dominion Boat Club in Alexandria, two cruisers sank and several docks washed away. Quantico saw most of its docks vanish. Fourteen sailboats met an untimely fate at the Washington Sailing Marina. Tides reached 8.7 feet above low water datum at Washington, D.C..

The battleship Kentucky broke its moorings and ran aground 100 feet away. The gun screw vessel Pirate was lost off West Norfolk. The Coast Guard beacon light on the Potomac at Morgantown was toppled by Hazel's winds. Thirteen across Virginia perished...2 in the District of Columbia ...damage estimates reached $15 million.
