A severe weather system brought heavy rain, high winds, hail and at least one confirmed tornado Thursday evening.
Here’s what you need to know now:

The weather service said the main threat from the storms will be “damaging wind gusts, but tornadoes cannot be ruled out.”
The National Weather Service issued a tornado warning for parts of Anne Arundel County, Maryland, including Annapolis, Parole and Edgewater, until 6:30 p.m.
Just after 6 p.m., the weather service confirmed that a tornado touched down just south of Annapolis in Anne Arundel County. They said the tornado was moving east toward the Bay Bridge and advised everyone in the area to take cover.

The weather service asked that residents stay alert to current weather conditions in their areas and to be ready to respond if hazardous conditions form.

Several tornado warnings were issued in Carroll, Howard, Montgomery, Baltimore and Prince George’s counties Thursday afternoon. The weather service reported seeing storm systems that were generating the rotating air currents needed to form a tornado in those areas.
Storm Team 4 meteorologist Mike Stinneford said the threat for serious storms would not diminish until after sunset.
“The main trigger for these storms is a strong cold front that is not likely to arrive until sometime around noon on Friday,” said Storm Team 4 meteorologist Chuck Bell.
He said that makes timing out the storm chances a little tricky and could help to keep the storms going well after sunset.

September tornadoes are not unheard of, but locally, the threat of tornadoes lessens by late summer and early fall.
The D.C. region’s most recent documented September tornado was a whirlwind that blew through Laurel, Maryland, on Sept. 29, 2015.
The weather service determined that numerous fallen trees and some roof damage was the work of a weak EF-0 tornado.
A couple of short-lived tornadoes briefly touched down along Route 234 in Southern Maryland in early September 2011.
Although Virginia’s Richmond area saw several twisters in September 2018, there haven’t been any confirmed September tornadoes in Northern Virginia since an exceptional severe weather outbreak in 2004.
By nightfall on Sept. 17, 2004, dozens of twisters had touched down, marking Virginia’s largest tornado outbreak in recorded history.
