Based on public NOAA and National Weather Service records, published under StormAuditor's methodology and data-source standards. Radar-derived hail sizes are estimates unless attributed to a ground report.
Maryland experienced significant severe weather events during the past year, with Montgomery County leading the pack with 17 events. Learn more about Maryland's severe weather history and how to research date of loss.
Introduction
Maryland runs from the Atlantic coast to the Appalachian Mountains. That range of land makes it prone to many kinds of severe weather. In StormAuditor's data, Montgomery County had the most events with 17. Carroll County came next with 14, then Howard County with 12.
Top Counties by Event Count
The top Maryland counties by event count are:
- Montgomery County: 17 events
- Carroll County: 14 events
- Howard County: 12 events
- Baltimore County: 8 events
- Caroline County: 8 events
These counties saw a range of severe weather, including hail and wind storms. Homeowners, contractors, and insurance adjusters need to know how strong and how frequent these events are in their area.
How StormAuditor Estimates Severe Weather
StormAuditor estimates wind and hail size with two methods:
- SAWE-2 (Storm Auditor Wind Estimate) for wind.
- SAHE-2 (Storm Auditor Hail Estimate v2) for hail.
Both rest on radar data and ground reports.
