WATCHES AND WARNINGS
--------------------

DISCUSSION AND OUTLOOK
----------------------
At 500 AM EDT (0900 UTC), the center of Post-Tropical Cyclone Fay
was located near latitude 42.4 North, longitude 73.9 West.  The
post-tropical cyclone is moving toward the north near 17 mph (28
km/h).  A north-northeastward motion at a faster forward
speed is expected today, tonight and Sunday.  On the forecast
track, the center of the post-tropical cyclone will continue to move
across portions of eastern New York this morning, then across
northwestern New England later today and over southeastern Canada
tonight and Sunday.

Maximum sustained winds are near 35 mph (55 km/h) with higher gusts.
Weakening is forecast during the next day so, and the
post-tropical cyclone is likely to dissipate by late Sunday.

The estimated minimum central pressure is 1001 mb (29.56 inches).


HAZARDS AFFECTING LAND
----------------------
RAINFALL:  The post-tropical cyclone is expected to produce 1 to 2
inches of rain with isolated maxima of 4 inches along and near its
track from eastern New York into portions of New England.  This
rain may result in flash flooding and urban flooding in areas with
poor drainage where the heaviest amounts occur.  Widespread river
flooding is not expected; however, rapid rises on small streams and
isolated minor flooding is possible.


NEXT ADVISORY
-------------
This is the last public advisory issued by the National Hurricane
Center on this system.

Post-Tropical Cyclone Fay Discussion Number   8
NWS National Hurricane Center Miami FL       AL062020
500 AM EDT Sat Jul 11 2020

The system has lacked significant organized deep convection for
some time now, and therefore it has degenerated into a
post-tropical low pressure system.  The maximum sustained winds are
estimated, perhaps generously, at 30 kt over the Atlantic waters
well to the southeast of the center.  Continued weakening is
likely, and the cyclone should dissipate over eastern Canada by
late Sunday.

The low is moving just east of due north or around 010/15 kt.  Over
the next day or so, the system should continue to move between a
mid-level ridge over the northwestern Atlantic and a trough near the
Great Lakes until it loses its identity.

This is the last advisory on this system.
