Isaias' remnants will impact Maryland into Monday. Here's what to expect.
Isaias made landfall as a Category 2 hurricane around 8:30 p.m. on Friday, near Destin, Florida. The system is no longer tropical. Still, widespread rain and a low risk of severe storms will impact the Mid-Atlantic through Sunday evening.
How will the remnants of Isaias impact Maryland?
The first round of widespread, steady rain has shifted north of Maryland, after dropping 2 to 3 inches of rain across much of the Baltimore metro, as well as central and western Maryland.
Another round of widespread rain and embedded thunderstorms will develop and track through Maryland Sunday evening. The chance of additional heavy rain peaks between 10 p.m. and 2 a.m. in Baltimore. A few spots could see total rainfall of more than 4 inches by the time dry weather finally arrives on Monday morning.
Though, the risk of flooding remains low and mainly confined to areas that typically see minor flooding during a heavy rain.
Isolated severe thunderstorms are possible Sunday evening. The main threats from any strong to severe storms would be from localized damaging wind gusts and an isolated tornado or two. The risk is greatest well south of Baltimore, down across Virginia.
Rainfall will help with the state's ongoing drought situation. The ground will absorb that amount of rain like a sponge and if heavy rain develops, we could see modest rises on areas reservoirs.
Some neighborhoods along the Chesapeake Bay will also experience coastal flooding with Sunday evening's high tide. The tide gauge near city dock is forecast to peak at 3.10' in Annapolis, causing minor to moderate coastal flooding in the typical trouble spots.
Monday morning will start showery, before drying out heading into the afternoon.
