A small tornado swirled across the National Mall and Tidal Basin during severe storms Thursday.
CEMA said there is the possibility for half-dollar sized hail and wind gusts of up to 60 miles per hour.
So far, 2017 has been a very active year for severe weather across the United States.
Thursday's tornado started near Highway 168 around 1:10 p.m., then raced northeast and north along a 4.7 mile path.
The tornado was the second to touch down in D.C. on Thursday.
"Destructive and long-track tornadoes will be possible, along with hail up to the size of baseballs, and damaging straight line winds", the weather service said. That number puts the Peach State in the lead for tornado reports, surpassing the usual leaders in the Great Plains.

With three more ties in the final minutes, a Valanciunas hook shot followed by a DeRozan jump shot gave Toronto a four-point lead. The numbers are ugly and yet Toronto is two wins away from its second consecutive 50-win season, and wrapping up the No. 3 seed.
The weather service confirmed that an EF1 tornado touched down in the Irvington area and an EF0 touched down in Chesapeake on Thursday.
Another EF-0 tornado was confirmed near Joint Base Anacostia-Bolling in the District of Columbia. And due to strong gusty winds, blowing and drifting snow is possible.
A third round will develop this evening through 9 p.m.
