OFFSHORE WATERS. AN ASCAT PASS FROM 1445Z DID INDICATE A FEW GALES
TO THE E OF THE NRN PORTION OF NT2 WATERS...HOWEVER THIS WAS IN AN
AREA OF CONVECTION AND SUSPECT THESE ARE LIKELY GUSTS. OVER THE
OFFSHORE WATERS...THE STRONGEST WINDS WERE MAINLY IN THE 20 TO 25
KT RANGE.

NRN AND CENTRAL NT2 WATERS...HOWEVER ALL OF THE MODELS DO KEEP
WINDS SUBGALE. HIGH PRES WILL BUILD OVER THE AREA SUN INTO EARLY
MON...WITH ANOTHER WEAK LOW MOVING ACROSS THE NT2 WATERS LATE MON
AND MON NIGHT. WILL POPULATE GRIDS USING THE 12Z GFS 30M WINDS
WHICH WILL RESULT IN ONLY MINOR CHANGES TO EXISTING FCST.

.SEAS...THE 18Z SEA STATE ANALYSIS INDICATED THAT OBSERVED SEAS
CONTINUE TO MATCH UP WELL WITH THE MWW3/ECMWF VALUES. WILL
POPULATE GRIDS USING THE MWW3 AS THERE ARE ONLY VERY MINOR
