.DISCUSSION...
Potential Tropical Cyclone Nine is off the north coast of Cuba and
will be moving northward, away from the forecast location this
weekend. Thus, significant wind and sea impacts are not
anticipated directly from Nine. However, abundant moisture will
bring widespread showers and thunderstorms to waters S of Cuba and
in the Windward Passage into Sunday. The stronger thunderstorms
will likely induce locally hazardous winds and seas. Away from the
thunderstorms, expect moderate to fresh southerly winds, with seas
of 3 to 5 ft.

 Latitude = 19.48N
