Tropical Storm Fay Discussion Number 3
NWS National Hurricane Center Miami FL AL062020
500 AM EDT Fri Jul 10 2020
An Air Force Hurricane Hunter aircraft investigating Fay early this
morning found that the storm had strengthened slightly, with
maximum SFMR-observed surface winds near 45 kt. Additionally, the
minimum central pressure had fallen a few mb since yesterday.
Since the center of the cyclone is exposed on the southwest side of
the main area of deep convection, and southwesterly shear over the
system is forecast to persist, little if any additional
strengthening is anticipated before landfall. Weakening should
commence after the center moves inland in 12-24 hours. The official
intensity forecast is in good agreement with the latest model
Center fixes from the Air Force plane show that the storm continues
moving northward at a slightly faster pace, or 360/9 kt. During
the next couple of days, Fay should move between a mid-level ridge
over the western Atlantic and a short-wave trough dropping into the
Ohio Valley region. There has been little change to the official
track forecast, which remains close to the simple and corrected
dynamical model consensus tracks.
1. Fay is expected to produce 2 to 4 inches of rain with isolated
maxima of 7 inches along and near the track from the lower Maryland
Eastern Shore and Delaware northward into New Jersey, eastern
Pennsylvania, southeast New York, and southern New England. These
rains may result in flash flooding where the heaviest amounts occur.
Widespread river flooding is not expected at this time.
2. Tropical storm conditions are expected along portions of the
mid-Atlantic and northeast coast today and tonight, and a
Tropical Storm Warning is in effect for the coasts of New Jersey,
New York and Connecticut, including Long Island.
