.SYNOPSIS...
PGUA RADAR SHOWS ISOLATED LIGHT SHOWERS. SATELLITE SHOWS FAIR SKIES
ACROSS THE LOCAL REGION. CLOUDINESS NEAR 20N150E IS ASSOCIATED WITH
AN UPPER-LEVEL TROUGH AND SURFACE CONVERGENCE. VAD GRADIENT WINDS

.DISCUSSION...
RELATIVELY DRY TRADE WINDS AND FAIR WEATHER ARE EXPECTED FOR THE
NEXT FEW DAYS. SOME CLOUDS AND A FEW SHOWERS COULD ARRIVE BY EARLY
NEXT WEEK SINCE MODELS INDICATE THAT PRESSURE GRADIENTS WILL TIGHTEN
ACROSS THE REGION OVER THE WEEKEND. TRADE WINDS WILL LIKELY FRESEHEN
BY SUNDAY OR MONDAY WITH A SHEAR LINE POSSIBLY FORMING ACROSS THE
LOCAL FORECAST ZONES...BUT STILL TOO MUCH UNCERTAINTY TO MAKE
SIGNIFICANT FORECAST CHANGES AT THIS TIME.

.MARINE...
GENTLE TO MODERATE TRADE-WIND CONDITIONS ARE EXPECTED THROUGH
SATURDAY...THEN MODELS INDICATE PRESSURE GRADIENTS WILL TIGHTEN
BY SUNDAY OR MONDAY SO THAT MARINE CONDITIONS WILL BECOME FRESH
TO POSSIBLY STRONG EARLY NEXT WEEK. WAVES GRIDS WERE ADJUSTED
WITH LATEST WW3 MODEL GUIDANCE AND WIND GRIDS WERE REEFRESHED
WITH ECMWF 27/12Z DATA.
