TROPICAL STORM FAY DISCUSSION NUMBER 10

The cloud pattern associated with Fay has become more symmetrical,
and microwave data also reveal that the inner core structure is
better than 12 hours ago, including the presence of a closed
mid-level eye feature. I was tempted to classify the system as a
hurricane, but the consensus of the Dvorak T-numbers still support
an initial intensity of 60 kt. No significant change in strength is
anticipated, but only a 5-kt increase in the winds will bring Fay to
hurricane status. A strong cold front is rapidly approaching the
cyclone, and extratropical transition will most likely occur in
about 24 hours.
Fay has turned to the right as anticipated, and the best estimate of
the initial motion is toward the northeast or 055 degrees at 21 kt.
Fay should accelerate even further and turn more to the east while
embedded in the fast mid-latitude westerly flow. The NHC forecast is
in the middle of the guidance envelope, and is a blend of the
previous forecast and the Ocean Prediction Center input.
