CHANCE OF THUNDERSTORMS IN THE FORECAST. BUT WONDERING IF THE

THE AREA AND PWAT FIELDS STILL A LITTLE LOW (< 0.5). HATE TO GO
AGAINST MODELS SO LEFT THE SLIGHT CHANCE IN. MODELS REMAIN IN GOOD
AGREEMENT IN UPPER RIDGE NOSING OVER THE REGION OVERNIGHT INTO

OMIT THE NORTHERN WATERS FROM HIGHER WINDS. THERE IS A SMALL CRAFT

TO 20 KT AT BUOY 22. A MORNING ASCAT PASS INDICATED 20 KT OFFSHORE,
