Tropical Storm Fay Discussion Number   7
NWS National Hurricane Center Miami FL       AL062020
1100 PM EDT Fri Jul 10 2020
 
Satellite and radar data indicate that Fay is no longer generating 
organized deep convection as the center moves into northern New 
Jersey.  A combination of radar, aircraft, buoy, and ship data show 
that 30-35 kt winds are occurring over the water south of central 
and western long Island, and based on this the initial intensity is 
reduced to 35 kt.  The central pressure of 1001 mb is based on 
surface observations.

Barring the return of convection, Fay should continue to weaken and 
become post-tropical on Saturday.  After that, the system is 
expected to dissipate on Sunday as it merges with a frontal system 
over southeastern Canada.  The new intensity forecast has only 
minor tweaks from the previous forecast.

The initial motion is now northward or 005 degrees at 15 kt.  The 
track forecast philosophy is unchanged, as Fay will be steered 
generally northward and north-northeastward until dissipation 
between a mid-level ridge over the western Atlantic and an 
approaching shortwave trough moving across the Great Lakes.  The 
storm is moving a little to the left of the previous forecast, so 
the new forecast is nudged to the left due mainly to the initial 
position and motion.  The new forecast lies close to the consensus 
models.
 
Users should not place too much emphasis on the exact track of the
center of Fay, as the heaviest rain and strongest winds are now 
occurring well away from the center.
 
Key Messages:
 
1. Heavy rainfall from eastern Pennsylvania, northeast New Jersey 
and across southeast New York, into portions of New England may 
result in flash flooding and urban flooding in areas with poor 
drainage.  Isolated minor flooding is possible; however, widespread 
river flooding is not expected.
 
2. Tropical storm conditions are expected for several more hours 
over portions of coastal New York and Connecticut, including most 
of Long Island.
