TROPICAL WEATHER DISCUSSION
NWS NATIONAL HURRICANE CENTER MIAMI FL
1605 UTC SUN SEP 7 2025
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 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
1500 UTC.
..TROPICAL WAVES
A TROPICAL WAVE EXTENDS FROM 07N TO 17N WITH AXIS NEAR 112W,
MOVING WESTWARD AT 5-10 KT. SCATTERED MODERATE CONVECTION IS
OBSERVED FROM 06N TO 15N AND BETWEEN 107W AND 113W.
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH EXTENDS FROM 08N78W TO 14N110W TO 12N140W.
SCATTERED MODERATE CONVECTION IS PRESENT WITHIN 200 NM ON EITHER
SIDE OF THE BOUNDARY.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO
LATEST SATELLITE IMAGERY DEPICT STRONG SHOWERS AND THUNDERSTORMS
IN THE GULF OF TEHUANTEPEC AND OFFSHORE SOUTHERN MEXICO.
MARINERS NAVIGATING THESE WATERS CAN EXPECT GUSTY WINDS AND
HIGHER SEAS. FARTHER NORTH, A SURFACE TROUGH IS ANALYZED FROM
29N117W TO 22N117W. LOCATED NEAR 26N117W, WELL WEST OF BAJA
CALIFORNIA SUR. A RECENT SCATTEROMETER SATELLITE PASS INDICATE
THAT MODERATE NORTHERLY WINDS ARE OCCURRING TO THE WEST AND NORTH
OF THE LOW CENTER. SEAS IN THESE WATERS ARE 5-6 FT. THE
REMAINDER OF THE MEXICAN OFFSHORE WATERS, INCLUDING THE GULFS OF
CALIFORNIA AND TEHUANTEPEC, ARE UNDER A WEAK HIGH PRESSURE REGIME
THAT SUPPORTS LIGHT TO GENTLE WINDS AND SLIGHT TO MODERATE SEAS.
FOR THE FORECAST, THE SURFACE TROUGH W OF BAJA WILL DISSIPATE
TONIGHT. MEANWHILE, MODERATE TO FRESH TO STRONG NW WINDS ARE
FORECAST TO DEVELOP OFFSHORE BAJA CALIFORNIA MON EVENING INTO
LATE THIS WEEK AS THE REMNANTS OF A FRONTAL BOUNDARY APPROACH
FROM THE WEST, SLIGHTLY INCREASING THE PRESSURE GRADIENT ACROSS
THE REGION. FRESH TO STRONG NORTHERLY WINDS ARE LIKELY TO PULSE
IN TEHUANTEPEC MON AND TUE AND THEN LATE IN THE WEEK.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
UNSETTLED WEATHER CONDITIONS CONTINUE TO BRING SCATTERED SHOWERS
AND ISOLATED THUNDERSTORMS TO THE OFFSHORE WATERS OF CENTRAL
AMERICA AND COLOMBIA. MEANWHILE, THE PRESSURE GRADIENT BETWEEN A
RIDGE IN THE SOUTH PACIFIC AND LOWER PRESSURES ASSOCIATED WITH
THE MONSOON TROUGH RESULT IN MODERATE TO OCCASIONALLY FRESH S-SW
WINDS AND MODERATE SEAS SOUTH OF THE MONSOON TROUGH, MAINLY
SOUTH OF 07N. LIGHT TO GENTLE WINDS AND SLIGHT TO MODERATE SEAS
ARE PRESENT ELSEWHERE.
FOR THE FORECAST, MODERATE TO FRESH SOUTHERLY WINDS AND MODERATE
SEAS IN S TO SW SWELL WILL CONTINUE ACROSS THE REGION THROUGH
LATE THIS WEEK. OTHERWISE, SCATTERED TO HEAVY SHOWERS ARE
FORECAST FOR THE CENTRAL AMERICA OFFSHORE WATERS THE NEXT SEVERAL
DAYS.
..REMAINDER OF THE AREA
THE IMPACTS OF HURRICANE KIKO IN THE TROPICAL EASTERN PACIFIC
CONTINUE TO DIMINISH AS THE CYCLONE MOVE FURTHER INTO THE CENTRAL
PACIFIC. RECENT SCATTEROMETER SATELLITE DATA SHOW THAT FRESH TO
STRONG EASTERLY WINDS ARE OCCURRING FROM 17N TO 22N AND WEST OF
135W. ROUGH SEAS ARE PRESENT FROM 12N TO 21N AND WEST OF 136W.
FOR MORE DETAILS ON THIS HURRICANE, PLEASE VISIT HURRICANES.GOV.
THE REST OF THE TROPICAL EASTERN PACIFIC IS DOMINATED BY A BROAD
SUBTROPICAL RIDGE CENTERED NEAR THE FAR NW CORNER OF THE BASIN.
MODERATE N-NE WINDS AND MODERATE SEAS ARE PRESENT ACROSS MUCH OF
THE WATERS NORTH OF THE MONSOON TROUGH AND BETWEEN 115W AND
135W. MODERATE TO LOCALLY FRESH SOUTHERLY WINDS AND MODERATE TO
LOCALLY ROUGH SEAS ARE FOUND SOUTH OF THE MONSOON TROUGH.
ELSEWHERE, CONDITIONS WILL CONTINUE TO IMPROVE ACROSS THE
WESTERN TROPICAL WATERS TODAY AS KIKO MOVES FURTHER WEST OF THE
AREA. MODERATE TO LOCALLY FRESH N-NE WINDS ARE FORECAST N OF THE
MONSOON AND W OF 110W THROUGH WED NIGHT. OTHERWISE, THE TROPICAL
WAVE CURRENTLY NEAR 111W WILL REACH NEAR 117W TONIGHT, ENHANCING
WINDS TO FRESH SPEEDS NEAR THE MONSOON AND SUPPORTING ROUGH SEAS
AS THE WAVE CONTINUES TO MOVE WESTWARD.
