NEAR TERM: Variable conditions, ranging from VFR to LIFR, will

NEAR TERM: A Small Craft Advisory for hazardous seas remains in
effect for much of the waters, with the exception of the
intracoastal waters, into this afternoon. Visibilities will be
reduced in areas of fog and showers today, could also have an
isolated thunderstorm this afternoon. Conditions are expected to
be below small craft advisory levels tonight.
SHORT TERM: For the sustained winds Saturday and Sunday will
initialize the grids with the NAM12 then lower the model winds by
10 percent due to relatively cold sea surface temperature. Will
transition to the Superblend winds late Sunday. For Waves: Expect
wind wave to continue to dominate through Monday with a secondary
southeasterly long period wave system (1 foot/14 seconds). Gaston
is expected to become a hurricane over the Weekend in the
Atlantic. Expect long period swell from this system to build to
around 4 feet/13-14 seconds late Monday into Tuesday as Gaston
moves well to the east over the Atlantic. Will use the Near Shore
Wave Model (NWPS) to populate the wave grids. Will lower NWPS wave
heights by 1 foot Saturday and Sunday as boundary conditions
appear a little high.
