SURVEY SUMMARY:
ON TUESDAY, AUGUST 11, 2026, THE NATIONAL WEATHER SERVICE
BALTIMORE/WASHINGTON WEATHER FORECAST OFFICE SENT A TEAM TO THE
CITY OF BALTIMORE AND BALTIMORE COUNTY TO SURVEY STORM DAMAGE
FROM THUNDERSTORMS THAT OCCURRED ON AUGUST 10, 2026. ADDITIONALLY,
SEVERAL VIDEOS FROM TRUSTED SOURCES WERE RECEIVED AND ANALYZED,
ALONG WITH WEATHER RADAR AND EYEWITNESS REPORTS.
VIDEO TAKEN FROM THE JOHNS HOPKINS BAYVIEW MEDICAL CENTER SHOWS A
BRIEF CIRCULATION, LIKELY A WATERSPOUT, OVER THE PATAPSCO RIVER
MOVING TOWARDS THE SEAGIRT MARINE TERMINAL, PORT OF BALTIMORE. AS
THE WATERSPOUT MOVED ONSHORE, IT BECAME TORNADIC, AND CONTINUED
EAST-NORTHEAST TOWARD BROENING HIGHWAY WHERE A LARGE HARDWOOD
TREE WAS UPROOTED AND ANOTHER HARDWOOD TREE WAS SNAPPED. THE
TORNADO CROSSED COLGATE CREEK AND A POWER POLE WAS SNAPPED ALONG
RALLS AVENUE JUST EAST OF COLGATE CREEK. THE TORNADO CONTINUED TO
TRACK EAST-NORTHEAST AND A VEHICLE WAS DISPLACED AROUND SOLLERS
POINT ROAD IN DUNDALK. A TREE WAS ALSO UPROOTED IN THIS AREA AND
AN AWNING WAS RIPPED OFF AN APARTMENT AS WELL. THE TORNADO
DISSIPATED AROUND THIS AREA. THE FAA TERMINAL DOPPLER WEATHER
RADAR FOR THURGOOD MARSHALL BWI AIRPORT (TBWI) SHOWED A TORNADIC
SIGNATURE ALONG THIS PATH, CORROBORATING THE DAMAGE OBSERVATIONS.
BASED ON RADAR OBSERVATIONS FROM NEARBY TBWI AND DAMAGE ON THE
GROUND, IT WAS DETERMINED THAT AN EF-0 TORNADO, WITH A MAXIMUM
VELOCITY OF 65 MPH, PATH WIDTH OF 90 YARDS, AND A PATH LENGTH OF
2.0 MILES OCCURRED MONDAY AFTERNOON IN THE CITY OF BALTIMORE AND
BALTIMORE COUNTY.
THE NATIONAL WEATHER SERVICE THANKS TRAINED SPOTTERS, MEDIA, AND
LOCAL EMERGENCY OFFICIALS FOR THEIR ASSISTANCE IN THIS SURVEY.
