Wicomico County

Every recorded tornado

1. Injuries and deaths are for the tornado’s whole path, which may extend beyond the county. Deaths recorded within Wicomico County: 0.
2. Weak tornadoes were under-recorded before Doppler radar coverage became national in the early 1990s, so earlier decades read low. Ratings use the Fujita scale before February 2007 and the Enhanced Fujita scale after.

Every storm within 100 miles

1. Tropical storms and hurricanes (34 kt or more, still tropical) at closest approach. Post-tropical remnants with gale-force winds are listed but not counted. Direct: track within 50 miles; near: within 100 miles. Distance is measured to the county boundary for counties and to the city centre for cities, using positions interpolated hourly between HURDAT2 fixes.

Smoke overhead

1. A smoke day is a date on which a smoke plume traced by NOAA Hazard Mapping System analysts from satellite imagery covered this place's point (the county's population centre or the city centre). Counts here are of medium or heavy smoke. Since 2018 analysts have often drawn light smoke as one area over most of the continent, so light-smoke counts are not comparable from year to year. The plumes show smoke anywhere in the air above, not air quality at the ground, and smoke hidden by cloud is missed.

1. The Palmer Drought Severity Index is computed by NOAA each month from the county's average temperature and precipitation, relative to the county's own climate. Zero is normal; -3 or lower is severe drought and -4 or lower extreme drought. It describes the long-term balance of moisture, not water supply or crop losses.

Every earthquake of magnitude 4 or more within 50 miles

1. Earthquakes of magnitude 2.5 or more in the USGS Comprehensive Catalog since 1900. Within 50 miles means the epicentre lies within 50 miles of the county boundary (or inside the county).
2. Small earthquakes were under-recorded before the modern seismic networks of the 1970s and are still missed in remote areas, so early decades read low. Magnitudes are as the catalogue reports them and mix scales (moment, local and body-wave).

1. Dec 23, 1998Ice Storm, Wicomico$5.0 million
   National Weather Service narrative

   A major ice storm affected the Lower Maryland Eastern Shore from Wednesday, December 23rd into Friday, December 25th. A prolonged period of freezing rain and sleet resulted in ice accumulations of one quarter inch /0.25/ to three quarters inch /0.75/ in many locations. The heavy ice accumulations on trees and power lines caused numerous power outages across the region. Many accidents occurred due to slippery road conditions, especially bridges and overpasses. Many secondary roads were impassable due to fallen tree limbs and in a few cases, whole trees.

2. Sep 1, 2006High Wind, Wicomico$1.0 million

The tornado then moved across Main Street, causing a house to be shifted off its foundation. A shed was also totally destroyed. In addition, bark was stripped off of trees. The tornado then lifted just north of Route 50 where large garage doors were blown in.

8. Oct 28, 2021Coastal Flood, Wicomico$150,000
   National Weather Service narrative

   Strong low pressure tracked from the Middle Mississippi Valley east northeast toward the Northeast United States from Thursday, October 28th into Saturday, October 30th. This system produced very strong east southeast winds, then strong south to southwest winds through the period. This caused moderate to major (tidal) coastal flooding across portions of Wicomico county adjacent to the Chesapeake Bay.
