In Howard County, numerous roads were closed due to flooding and downed trees -- mostly in the Columbia, Ellicott City and Elkridge areas.

Main Street in Ellicott City and surrounding roads were closed as a precaution. A Tornado Warning and Flash Flood Warning was issued for parts of the Howard County area.

"The impact of Wednesday night’s storm was felt across our community," said Howard County Executive Calvin Ball Thursday. "Nearly 30 roads across the county were effected by flooding or downed trees. In Ellicott City, a flash flood warning triggered our outdoor tone alert system to notify residents to seek high ground. This and other initiatives we’ve implemented through Ellicott City Safe and Sound made us more prepared."


In Columbia, the strong storms prompted the Merriweather Post Pavilion to cancel a Halsey concert following a lengthy delay. The concert was called off around 10 p.m. Videos posted online show water rushing through parts of the venue as the storm raged.

Merriweather tweeted that concertgoers should look for more information about the cancellation from their ticket sellers. Halsey also tweeted a message to fans.

A dry and mostly sunny Thursday is expected with high temperatures in the 80s.
