0405 UTC SAT JUN 20 2026
TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN FROM
03.4S TO 30N, EAST OF 120W INCLUDING THE GULF OF CALIFORNIA, AND
FROM THE EQUATOR TO 30N, BETWEEN 120W AND 140W. THE FOLLOWING
INFORMATION IS BASED ON SATELLITE IMAGERY, WEATHER OBSERVATIONS,
RADAR, AND METEOROLOGICAL ANALYSIS.
BASED ON 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0305 UTC.
..TROPICAL WAVES
A TROPICAL WAVE IS ALONG 90W, SOUTH OF 16N, MOVING WEST AT 5 TO
10 KT. SCATTERED MODERATE CONVECTION IS NOTED FROM 02N TO 07N AND
BETWEEN 85W AND 93W.
A TROPICAL WAVE IS ALONG 97W, SOUTH OF 15N, MOVING WEST AT 5 KT.
SCATTERED MODERATE TO ISOLATED STRONG CONVECTION IS OBSERVED
FROM 02N TO 10N AND BETWEEN 93W AND 100W.
A TROPICAL WAVE IS ALONG 116W, SOUTH OF 18N, MOVING WEST AT 5 TO
10 KT. SCATTERED MODERATE TO ISOLATED STRONG CONVECTION IS
PRESENT FROM 09N TO 17N AND BETWEEN 104W AND 120W.
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH EXTENDS FROM THE COAST OF COSTA RICA NEAR
10N85W TO 07N97W TO 13N113W TO 06N131W. THE ITCZ STRETCHES FROM
06N131W TO BEYOND 06N140W. SCATTERED MODERATE CONVECTION IS
EVIDENT SOUTH OF 10N AND WEST OF 120W.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO
HIGH PRESSURE DOMINATES THE OFFSHORE WATERS OF MEXICO. THE
MODERATE PRESSURE GRADIENT BETWEEN THE STRONG RIDGE IN THE NE
PACIFIC AND LOWER PRESSURES IN NW MEXICO RESULT IN MODERATE TO
LOCALLY FRESH NORTHERLY WINDS IN THE OFFSHORE WATERS OF BAJA
CALIFORNIA. SEAS IN THESE WATERS ARE 5-7 FT. IN THE REMAINDER OF
THE MEXICAN OFFSHORE WATERS, INCLUDING THE GULF OF TEHUANTEPEC,
MODERATE OR LIGHTER WINDS AND SLIGHT TO MODERATE SEAS PREVAIL.
FOR THE FORECAST, A RIDGE WILL REMAIN IN PLACE ACROSS THE OFFSHORE
FORECAST WATERS OF BAJA CALIFORNIA PROMOTING GENTLE TO MODERATE
NORTHERLY WINDS, EXCEPT FOR LOCALLY FRESH SPEEDS PULSING AT NIGHT
THROUGH THE WEEKEND. LOOKING AHEAD, A SURFACE TROUGH MOVING ACROSS
THE BAY OF CAMPECHE WILL FORCE FRESH TO STRONG NORTHERLY GAP WINDS
IN THE GULF OF TEHUANTEPEC LATE TUE NIGHT INTO WED NIGHT, WITH
SEAS BUILDING TO 8 OR 9 FT BY WED NIGHT.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
HIGH PRESSURE NORTH OF THE CARIBBEAN SEA FORCES MODERATE EASTERLY
TRADE WINDS AND MODERATE SEAS ACROSS THE GULF OF PAPAGAYO.
MAINLY MODERATE SOUTHERLY WINDS AND MODERATE SEAS ARE PRESENT
SOUTH OF THE EQUATOR. ELSEWHERE, LIGHT TO GENTLE WINDS AND SLIGHT
TO MODERATE SEAS PREVAIL.
FOR THE FORECAST, GENTLE TO MODERATE SOUTHERLY WINDS AND
MODERATE SEAS WILL PREVAIL ACROSS THE OFFSHORE WATERS BETWEEN
ECUADOR AND THE GALAPAGOS ISLANDS THROUGH EARLY NEXT WEEK.
MEANWHILE, MODERATE TO FRESH NE TO E WINDS AND MODERATE SEAS ARE
EXPECTED IN THE PAPAGAYO REGION INTO EARLY NEXT WEEK. WINDS WILL
FRESHEN TO STRONG SPEEDS STARTING LATE MON WITH SEAS BUILDING TO
8 OR 9 FT BY LATE TUE. ELSEWHERE, LIGHT TO GENTLE WINDS AND
SLIGHT TO MODERATE SEAS IN SOUTHWEST SWELL ARE FORECAST ELSEWHERE
THROUGH THE NEXT SEVERAL DAYS.
..REMAINDER OF THE AREA
HIGH PRESSURE CENTERED WELL NORTH OF THE AREA DOMINATES THE
REMAINDER OF THE TROPICAL EASTERN PACIFIC. MODERATE NE-E WINDS
AND MODERATE SEAS ARE FOUND NORTH OF THE ITCZ TO 20N AND WEST OF
130W. IN THE MEANTIME, MODERATE SE WINDS AND SEAS OF 6-8 FT ARE
NOTED SOUTH OF 05N AND EAST OF 120W. ELSEWHERE, LIGHT TO GENTLE
WINDS AND MODERATE SEAS ARE PREVALENT.
FOR THE FORECAST, ADDITIONAL PULSES OF SW SWELL WILL CONTINUE TO
PROPAGATE ACROSS THE FORECAST WATERS E OF 120W GENERATING MODERATE
TO LOCALLY ROUGH SEAS. OTHERWISE, LITTLE CHANGES ARE EXPECTED IN
WINDS AND SEAS THROUGH THE UPCOMING WEEKEND AND INTO EARLY NEXT
WEEK AS A RIDGE REMAINS IN CONTROL OF THE WEATHER PATTERN ACROSS
THE AREA. TROPICAL CYCLONE FORMATION IS NOT EXPECTED DURING THE
NEXT 7 DAYS.
