The National Weather Service has confirmed an EF-0 tornado touched down near Battle Creek in the St. Leonard area of Calvert County during severe storms that moved through Southern Maryland on Monday, June 22, 2026.
The tornado was listed by the National Weather Service as the “Mutual MD Tornado.” It touched down at approximately 7:02 p.m. about 2.7 miles west of Mutual and lifted at approximately 7:04 p.m. about 1.3 miles west of Mutual.
According to the National Weather Service Baltimore/Washington Weather Forecast Office, the tornado had estimated peak winds of 75 mph, a path length of 1.3 miles, and a maximum width of 75 yards. No injuries or fatalities were reported.
The tornado developed as a line of severe thunderstorms moved east into Southern Maryland, causing a widespread severe weather outbreak across portions of Maryland and Virginia.
The National Weather Service reported that one of the storms developed rotation as it moved out of St. Mary’s County and crossed the Patuxent River into Calvert County. Once the storm moved into Calvert County, Terminal Doppler weather radar at Joint Base Andrews showed the rotation strengthening as it approached Battle Creek while moving east at approximately 50 mph.
A drone video captured the tornado developing. Tornadic damage was first reported off Honey Cove Court on the west shore of Battle Creek, where several large branches were snapped from trees and one branch fell onto a dock.
An eyewitness on Shamrock Court, on the east shore of Battle Creek, reported seeing the tornado cross the creek before taking shelter.
Additional tree damage was reported along Shamrock Court, Crane Road, and Shannon Way. An eyewitness off Crane Road also provided video showing rotating and lofted leaf debris.
After crossing Shannon Way, the tornado lifted. The National Weather Service reported that intermittent minor tree damage continued in St. Leonard, but that damage was caused by downburst winds after the storm’s rotation weakened.
An EF-0 tornado is the lowest rating on the Enhanced Fujita Scale, with estimated winds between 65 and 85 mph.
The National Weather Service thanked the Calvert County Office of Emergency Management for its assistance, as well as trained spotters, media members, and residents who provided videos and damage reports from the storm.
