F1 tornado, Faulkner to Newport, Maryland, May 18, 2002

From Faulkner to Newport, this F1 tornado ran 5.0 miles across Charles County on May 18, 2002, touching down at 7:25 AM EDT and reaching 50 yards wide. It killed nobody, and did $20,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mphthis tornado

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

Scattered thunderstorms pushed through Southern Maryland between 7 and 9 AM EDT on the 18th. These storms produced damaging wind gusts in addition to three waterspouts. High wind gusts downed trees in Charles, Calvert, and St. Mary's Counties. Communities reporting downed trees included Nanjemoy, Malcolm, Wallville, St. Leonard, and Dunkirk. On the Potomac River, a waterspout formed about three miles north of the Route 301 bridge. It became a tornado as it struck land about 2 miles south of Faulker at F1 strength (60 to 80 MPH winds). It stayed on the ground for 5 miles and was 50 yards wide. The tornado first struck Popes Creek Road, then pushed east to Budds Creek Road near the intersection of Route 301. Next, it crossed the Wicomico River near the Zekiah Swamp Natural Environment Area. Several boats were damaged. Finally, it crossed Allens Fresh Road before dissipating about ½ mile south of Newport. Along its rural path it downed several trees, removed shingles and screen doors from homes, and destroyed a few sheds and barns. Two other waterspouts were spawned on the Chesapeake Bay. The first waterspout formed near Parker Creek, east of Prince Frederick on the Western Shore. It flipped a boat and sent the three people aboard into the water. One person was injured. The other waterspout formed near the Eastern Shore off Blackwater Point on Tighman Island. A wind gust of 42 knots was recorded at the Choptank River Sensor nearby.

A tornado damaged barns and downed trees along its 5 mile rural path.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 04:55 UTC.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
