Tropical Storm Teddy Discussion Number 11
NWS National Hurricane Center Miami FL AL202020
500 AM AST Tue Sep 15 2020

The tropical storm appears to have gotten better organized
overnight, with deeper convection near the center and an increase in
banding features. The initial wind speed is nudged upward to 50 kt,
a little lower than the subjective Dvorak estimates alone would
indicate since they have been running a little hot for this storm.
While there are no signs of a true inner core yet, the shear is
quite low at present, and Teddy should have several days in a low or
moderate shear environment over warm waters to strengthen. Thus,
the new forecast is raised from the previous one and is closest to a
blend of the Florida State Superensemble and the NOAA corrected-
consensus guidance. Teddy bears watching in the long range for
category 4 strength, but regardless of the details, all of the
guidance show it becoming a classical large and powerful September
hurricane.

The storm has turned west-northwestward tonight, or 295/10 kt.
Teddy remains in a well-defined steering current for the next
several days on the southwestern edge of the central Atlantic
ridge, causing a west-northwest to northwest track through the
end of the forecast. While the guidance is in very good agreement,
there`s been a rightward shift of almost all the aids, perhaps due
to more upper-level westerly flow than the last cycle. The NHC
track forecast is shifted eastward but lies on the western side of
the guidance envelope.
