Meteorological Analysis
|
Grace originated from a cold front which stretched from the Caribbean out into the Atlantic
in mid-October. The low that spawned Grace formed near Hispaniola and reached gale
strength on the 15th. Convection then formed over the center of the low, resulting in the
low becoming warm core. On the 16th the low was organized enough to be considered
tropical storm Grace. Grace was still elongated along the front however and connected to
other lows along the front, making it slightly extratropical. Grace then raced ENE under a
large extratropical cyclone which was just south of Newfoundland. Grace also encountered
high shear in this environment, and only attained maximum winds of 45 mph. Shear
eventually took its toll on Grace and Grace dissipated completely on the 17th.
