NWS NATIONAL HURRICANE CENTER MIAMI FL
1005 UTC MON JUN 22 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 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0920 UTC.
..TROPICAL WAVES
A TROPICAL WAVE IS ALONG 90W, SOUTH OF 16N, MOVING WESTWARD AT
15-20 KT. SCATTERED MODERATE TO ISOLATED STRONG CONVECTION IS
PRESENT FROM 03N TO 14N BETWEEN 83W AND 94W.
A TROPICAL WAVE IS ALONG 97W, SOUTH OF 15N, DRIFTING WESTWARD AT
5-10 KT. SCATTERED MODERATE CONVECTION IS ACTIVE FROM 06N TO 11N
AND BETWEEN 94W AND 101W.
A TROPICAL WAVE IS ALONG 106W, SOUTH OF 16N, MOVING WESTWARD AT
5-10 KT. SCATTERED MODERATE CONVECTION IS OBSERVED FROM 06N TO
13N BETWEEN 104W AND 110W.
A TROPICAL WAVE IS ALONG 125W, SOUTH OF 17N, DRIFTING WESTWARD
AT 5 KT. NO SIGNIFICANT CONVECTION IS EVIDENT NEAR THIS WAVE.
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH
THE MONSOON TROUGH EXTENDS FROM 10N85W TO 12N110W TO 09N125W.
THE ITCZ EXTENDS FROM 09N125W AND BEYOND 08N140W. ASIDE FROM THE
CONVECTION ASSOCIATED WITH THE TROPICAL WAVES, SCATTERED MODERATE
CONVECTION IS EVIDENT OFFSHORE PANAMA AND COLOMBIA, FROM 07N TO
14N BETWEEN 110W AND 118W, AND FROM 04N TO 10N W OF 130W.
..OFFSHORE WATERS WITHIN 250 NM OF MEXICO
MODERATE TO FRESH NW WINDS ARE ACROSS THE BAJA CALIFORNIA
OFFSHORE WATERS ALONG WITH 5-6 FT SEAS. THE STRONGEST WINDS ARE
N OF CABO SAN LAZARO. IN THE SOUTHERN GULF OF CALIFORNIA, WINDS
ARE GENTLE TO MODERATE FROM THE SE AND SEAS ARE SLIGHT. ELSEWHERE,
LIGHT TO GENTLE WINDS AND SLIGHT TO MODERATE SEAS PREVAIL.
FOR THE FORECAST, RIDGING OVER THE EASTERN PACIFIC WILL SUPPORT
MODERATE TO FRESH NW WINDS OFF BAJA CALIFORNIA THROUGH TONIGHT,
AND GENTLE TO MODERATE BREEZES ELSEWHERE. WINDS OFF BAJA
CALIFORNIA WILL DIMINISH STARTING TUE AS THE HIGH PRESSURE
WEAKENS AHEAD OF A TROUGH MOVING INTO THE AREA FROM OFF SOUTHERN
CALIFORNIA. THIS PATTERN WILL ALSO SUPPORT MODERATE TO FRESH
SOUTHERLY WINDS ACROSS THE GULF OF CALIFORNIA TUE AHEAD OF THE
TROUGH. LOOKING AHEAD, EXPECT FRESH TO STRONG NORTHERLY GAP WINDS
AND ROUGH SEAS ACROSS THE GULF OF TEHUANTEPEC BY MIDWEEK, AS
PRESSURE LOWERS FARTHER SOUTH INTO THE TROPICS.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
MODERATE TO FRESH NE TO E GAP WINDS AND SEAS TO 5 FT ARE EVIDENT
ACROSS THE GULF OF PAPAGAYO REGION, EXTENDING DOWNSTREAM TO 90W.
FARTHER SOUTH, GENTLE TO MODERATE SOUTHERLY WINDS AND MODERATE
SEAS ARE OCCURRING BETWEEN ECUADOR AND THE GALAPAGOS ISLANDS.
ELSEWHERE, LIGHT TO GENTLE WINDS AND SLIGHT TO MODERATE SEAS
PREVAIL.
FOR THE FORECAST, MODERATE TO FRESH EASTERLY TRADE WINDS AND
MODERATE SEAS ARE EXPECTED IN THE PAPAGAYO REGION THROUGH TODAY.
WINDS WILL REACH FRESH TO STRONG SPEEDS STARTING TONIGHT WITH
SEAS BUILDING TO 9 FT BY LATE TUE. THE GAP WINDS IN THE GULF OF
TEHUANTEPEC WILL PRODUCE SEAS TO 9 FT IN THE FAR OFFSHORE WATERS
OF GUATEMALA BY MIDWEEK. MEANWHILE, MAINLY MODERATE SOUTHERLY
WINDS AND MODERATE TO LOCALLY ROUGH SEAS WILL PREVAIL ACROSS THE
OFFSHORE WATERS BETWEEN ECUADOR AND THE GALAPAGOS ISLANDS THROUGH
FRI.
..REMAINDER OF THE AREA
THE SUBTROPICAL RIDGE CENTERED WELL NW OF OUR WATERS EXTENDS
ACROSS THE EASTERN PACIFIC WATERS NORTH OF 20N. GENTLE TO
MODERATE NE TO E WINDS AND MODERATE SEAS ARE FOUND FROM 10N TO
20N WEST OF 115W. FARTHER SOUTH, LONG PERIOD SW SWELL WITH WAVE
HEIGHTS OF 7-9 FT ARE MOVING INTO THE WATERS SOUTH OF 03N
BETWEEN 101W AND 120W. ELSEWHERE, MODERATE OR WEAKER WINDS AND
MODERATE SEAS PREVAIL.
FOR THE FORECAST, ADDITIONAL PULSES OF SW SWELL WILL CONTINUE TO
PROPAGATE ACROSS THE FORECAST WATERS EAST OF 125W GENERATING
MODERATE TO LOCALLY ROUGH SEAS. OTHERWISE, LITTLE CHANGES ARE
EXPECTED IN WINDS AND SEAS THROUGH EARLY NEXT WEEK AS A RIDGE
REMAINS IN CONTROL OF THE WEATHER PATTERN ACROSS THE AREA.
LOOKING AHEAD, A TROPICAL WAVE A FEW HUNDRED MILES OFF THE COAST
OF SOUTHWESTERN MEXICO IS FORECAST TO MOVE WESTWARD AT 10-15 KT
ACROSS THE CENTRAL AND WESTERN PORTION OF THE BASIN, AND SOME
SLOW DEVELOPMENT IS POSSIBLE TOWARD THE END OF THE WEEK. ALSO, A
LOW PRESSURE SYSTEM IS EXPECTED TO FORM LATE THIS WEEK SEVERAL
HUNDRED MILES OFFSHORE OF THE COAST OF SOUTHWESTERN MEXICO. SOME
SLOW DEVELOPMENT OF THIS SYSTEM IS POSSIBLE AFTER THAT TIME WHILE
IT MOVES WEST-NORTHWESTWARD AT 10-15 KT.
