Tornado Risk in Baltimore County, MD
Baltimore County, MD: what NOAA's tornado record says
31 tornado tracks have crossed Baltimore County since 1973 by NOAA's count, roughly one every 2.5 years - the Elevated band on this site's scale. That is the 71st percentile nationally for tornado frequency. Within Maryland alone, Baltimore County ranks 4 of 24 counties for tornado frequency.
The number that matters more than frequency
No violent (EF4-5) tornado has been recorded in Baltimore County in NOAA's 76-year database. Of its 31 recorded tracks, 28 were weak (EF0-1) and 3 significant (EF2-3).
Shelter and safe-room economics
Maryland does not currently have a confirmed state rebate layered on top of FEMA's 75% Hazard Mitigation cost-share, so a Baltimore County homeowner should expect the full national range: $2,890-$13,280, $7,645 typical.
Power after the storm, not just shelter during it
852,425 people live in Baltimore County, and a tornado outbreak's power loss usually reaches far more of Maryland than the tracks themselves touch. A portable battery unit is the faster, no-fuel way to bridge that outage.
What Baltimore County's figure does not tell you
Baltimore County's figure is county-wide, not address-specific. Baltimore County covers about 598 square miles, so a single touch here counts the same as a single touch in a county a fraction of that size. NOAA also documents that older records undercount weaker tornadoes from before Doppler radar became standard. Baltimore County has about 852,425 residents.
