US - East

 . . . “There is an increasing risk of two life-threatening impacts from Florence: Storm surge at the coast and freshwater flooding from a prolonged heavy rainfall event inland,” the National Hurricane Center wrote Sunday . . . We are particularly concerned about the rainfall potential in the Mid-Atlantic. Models have come into agreement that a northward turn before reaching the United States is unlikely and that a building high-pressure zone north of the storm will cause it to slow or stall once it reaches the coast or shortly thereafter.

Florence could sit over some part of the Mid-Atlantic for several days, similar to what Harvey did last year over eastern Texas. It has the potential to dump unthinkable amounts of rain over a large area in the Mid-Atlantic and perhaps into the Northeast. Rainfall could begin Friday or Saturday and continue into the following week. Where exactly the zone of heaviest rain sets up is a big uncertainty. It could reasonably occur anywhere between the mountains and the coast . . .
