Concerns of flash flooding across the Baltimore region diminished Tuesday afternoon as the remnants of what was Hurricane Florence move out of the area.

Heavy rains overnight dumped more than 3 inches of rain in some areas, prompting flash flood warnings.


That caused service on the MARC train’s Camden Line to be canceled Tuesday morning due to flooding, and the Penn Line was experiencing delays.

Wind warnings were also in effect on the Francis Scott Key Bridge as well as the Bay Bridge. Northbound lanes of the Harbor Tunnel on Interstate 895 were closed for a seven-car crash.

A flash flood watch was in effect Tuesday morning as more rounds of rain moved through, but the National Weather Service canceled it by 2 p.m.

Weather service meteorologists said rain was being pushed off to the east as Florence’s remnants move toward New England. Drier air is forecast to move into the region Tuesday night and Wednesday.

Overnight, more than 2 inches of rain were reported in many areas: 3.32 inches in Laurel, 3.01 inches at the Maryland Science Center, 2.67 inches in Arbutus and 2.37 inches in Columbia, according to the National Weather Service.

Florence brought devastating flooding to the Carolinas, leaving at least 32 people confirmed dead, including 25 in North Carolina.

Downgraded from a tropical depression, the storm still had abundant rain and top winds around 25 mph. Forecasters said it was expected to continue toward the Northeast, which is in for as much as 4 inches of rain, before the system moves offshore again.

Preliminary statistics from the National Oceanic and Atmospheric Administration showed Florence had the fourth-highest rainfall total of any hurricane to hit the U.S. mainland since 1950, with 35.94 inches in Elizabethtown, N.C. Harvey’s total of 60.58 inches last year in Texas is No. 1.

Because of severe weather across much of the East Coast and ongoing response efforts, the Federal Emergency Management Agency announced that a national emergency alert test has been postponed to the backup date of Oct. 3 at 2:18 p.m.
