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.
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.
#Florence produced one of the most significant rainfall events on record in the Carolinas. Over a large portion of the region, observed rainfall had an estimated less-than 1% chance of occurring in any given year, indicating a rare and historic event. pic.twitter.com/NZ15sO8D6i
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.
