The National Weather Service confirmed a tornado touched down near Interstate 95 in northern Virginia.
People stuck in traffic on the highway used their cell phones to take pictures and video of the twister, which crossed over I-95 near Quantico about 5:30 p.m. Thursday.
Darlene Brock, who sent in video of the storm, said it only took a few seconds for the funnel cloud to form.
Severe weather struck around the Washington region Thursday evening.
