I do NOT claim to be an expert and is why I am asking these questions.
The track covers all stages of the storm development and degeneration. If you look at the NHC forecast track, it has a letter at each plot point. H=hurricane, S=tropical storm, D=depression. The black background for each point means the system has tropical characteristics. The D with the white background up in New England area means the storm is expected to be extra-tropical.
If you see the little letters in the track you can see it changes from “H” hurricane, to “S”, which is a tropical storm, to “D”, which is a tropical depression, as it makes its way north.
FORECAST TRACK POSITIONS
The letters give the projected sustained winds which are included in the track.
As others have said, it will just be a rain storm with maybe a little extra wind when it hits the Northeast.
However, the timing of the storm there could affect the ALDS, whose game 4’s are scheduled for Boston and New York on Monday. Luckily, Tuesday is a “travel day” in the schedule, so if the Red Sox and/or the Yankees survive tomorrow’s game 3s, the Monday games can be pushed back a day with no real effect.
