..SPECIAL FEATURES
GULF OF TEHUANTEPEC GALE WARNING: THE AREA OF HIGH PRESSURE N OF THE
AREA RESPONSIBLE FOR THE TIGHT PRESSURE GRADIENT HAS WEAKENED
SLIGHTLY. THIS HAS LOOSENED THE PRESSURE GRADIENT ACROSS THE AREA
ENOUGH TO DIMINISH WINDS BELOW STORM FORCE. STRONG GALE- FORCE WINDS
ARE OVER THE GULF OF TEHUANTEPEC THIS MORNING.
SEAS ARE PEAKING NEAR 25 FT. THE AREA OF HIGH PRESSURE N OF THE
AREA WILL CONTINUE TO WEAKEN AND SHIFT EASTWARD. THIS WILL
FURTHER LOOSEN THE PRESSURE GRADIENT ACROSS THE AREA, AND WINDS
WILL GRADUALLY DIMINISH THROUGH THE DAY. BY WED MORNING, WINDS
WILL DIMINISH BELOW GALE FORCE. MARINE CONDITIONS WILL THEN
FURTHER IMPROVE THROUGH THE DAY ON WEDNESDAY. LARGE SEAS
GENERATED FROM THIS VERY STRONG GAP WIND EVENT WILL SPREAD WELL
AWAY FROM THE TEHUANTEPEC AREA, WITH SEAS 8 FT OR GREATER ALREADY
REACHING AS FAR WEST AS 107W, AND AS FAR SOUTH THAN 03N THIS
MORNING.
GULF OF PAPAGAYO GALE WARNING: THE PRESSURE GRADIENT BETWEEN
HIGH PRESSURE BUILDING N OF THE AREA AND THE EQUATORIAL TROUGH IS
SUPPORTING GALE-FORCE NE TO E GAP WINDS OVER THE PAPAGAYO
REGION, WITH STRONG TO NEAR- GALE FORCE WINDS EXTENDING
DOWNSTREAM OF THE GULF. THE GALE-FORCE WINDS ARE GENERATING VERY
ROUGH SEAS IN THE GULF OF PAPAGAYO, WITH ROUGH SEAS EXTENDING
DOWNSTREAM OF THE GULF. GALE CONDITIONS WILL REMAIN THROUGH WED
MORNING.
MARINE INTERESTS TRANSITING ACROSS OR IN THE GULF OF
TEHUANTEPEC AND PAPAGAYO REGIONS SHOULD BE AWARE OF THESE GALE
FORCE GAP WIND EVENTS AND TAKE THE NECESSARY ACTION TO AVOID THE

CENTERED NEAR 31N123W. THE PRESSURE GRADIENT BETWEEN THE AREA OF
HIGH PRESSURE AND THE COLD FRONT OVER THE NW WATERS IS SUPPORTING
FRESH SW WINDS AHEAD OF THE FRONT. THE PRESSURE GRADIENT BETWEEN
THE AREA OF HIGH PRESSURE AND LOWER PRESSURE IN THE VICINITY OF
THE ITCZ IS SUPPORTING MODERATE TO FRESH TRADE WINDS SOUTH OF 15N
AND W OF 110W. FRESH TO STRONG WINDS EXTENDING FROM THE GULF OF
