.SYNOPSIS...Fresh northeast to east winds and elevated wave
heights will transition over the weekend to more favorable wind
and sea conditions next week. The weather will remain unsettled
with isolated to scattered showers and thunderstorms developing
from time to time. A disturbance in the Southwest Gulf of Mexico
has a chance of developing into a tropical system over the next
few days. Due to uncertainty, the current forecast does not yet
incorporate less favorable winds and waves that would accompany a
tropical system potentially developing this weekend into early
next week.
