Thunderstorms and two tornadoes barreled through the D.C. area Thursday, uprooting trees, ripping down power lines, tearing materials from rooftops and cascading debris onto streets and highways. The National Weather Service confirmed Thursday night that two EF-0 tornadoes with winds between 60 to 70 mph touched down, one at a D.C. military base and

another in nearby suburban Northern Virginia. One tornado hit Joint Base Anacostia-Bolling in Southeast D.C. and had a one-mile path. Another tornado touched down in Herndon, Virginia, for nearly one mile. An EF-0 is the lowest ranking on the Enhanced Fujita scale, which measures tornadoes by wind estimates based on damage. MORE
