Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Wed Jun 17 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
0930 UTC.

...TROPICAL WAVES...

The axis of a tropical wave is near 86W extending from 02N 
northward to across Nicaragua and into the Gulf of Honduras, 
moving westward at around 15-20 kt. Nearby convection is 
described with the monsoon trough below.

The axis of a tropical wave is now analyzed near 106W extending 
from 03N to 16N. Nearby convection is described with the monsoon
trough below.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...

The monsoon trough extends from the SW Caribbean Sea near 10N74W
to across Costa Rica, reaching from the Gulf of Papagayo at 
11N86W to 12N100W to 09N115W. The ITCZ extends from 09N115W to 
06N126W to 09N136W just to the SE of a surface trough, remnant of 
former Invest EP93. Scattered moderate isolated strong 
convection is from 02N to 15N E of 100W. Scattered moderate
convection is from 08N to 14N between 109W and 120W. Numerous
moderate to strong convection is from 10N to 12N W of 138W.

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface trough extends from the northern Gulf of California  
into Baja California Sur to Cabo San Lucas. The pressure 
gradient between the trough and surface ridging to the west is 
supporting moderate to fresh NW winds across the Baja Peninsula 
offshores along with moderate seas to 7 ft in S-SW swell. In the 
Gulf of California, winds are gentle to moderate from the SSW 
and seas remain slight north of the entrance of the gulf. A weak 
pressure gradient across the remainder discussion waters is 
supporting light to gentle winds with moderate seas to 6 ft in 
S-SW swell. Active convection is present across the offshore 
waters from Chiapas to Guerrero, including the Gulf of 
Tehuantepec as described above.

For the forecast, gentle to moderate winds will prevail across 
the waters of Baja California, pulsing to locally fresh speeds at
night. Gentle to occasionally moderate winds are expected inside
the Gulf of California and near the tip of Baja California Sur, 
reaching to locally fresh speeds today into early Thu. Light to 
gentle winds will prevail over the waters between Cabo Corrientes
and Tehunatepec. Moderate seas in mainly southerly swell will 
prevail through the next several days, slight in the Gulf of 
California. 

....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...

Mainly light to gentle winds under a weak pressure gradient 
prevail across the offshore waters along with slight to moderate
seas in SW swell. Otherwise, scattered heavy showers and tstms 
are across the offshore waters from Nicaragua northwestward to 
offshore Guatemala as described within the monsoon trough section
above. Winds and seas may be higher in and near these areas of 
deep convection.

For the forecast, gentle to occasionally moderate S to SE winds 
and moderate seas will prevail across the offshore waters between
Ecuador and the Galapagos Islands through Sun night. Moderate 
winds will pulse to fresh in diurnal offshore flow in the 
immediate Gulf of Papagayo beginning Fri night. Light to gentle 
winds and slight to moderate seas in SW swell are forecast 
elsewhere. 

...REMAINDER OF THE AREA...

A surface trough, remnant of Invest EP93, extends from 08N to 15N
and is producing a cluster of heavy showers and thunderstorm 
activity from 10N to 12N W of 138W. Moderate to fresh winds are 
within 150 nm either side of the trough N of 11N. Moderate to 
rough seas to around 8 ft are also within these winds. Elsewhere,
moderate or weaker winds and moderate seas prevail.

For the forecast, the remnants of former Invest EP93, will move 
W of 140W later today. Elsewhere, moderate or weaker winds, and 
moderate seas will prevail, except seas building to rough south 
of and near the Equator and east of 120W in new southerly swells 
through the end of the week. Winds may pulse to fresh in the 
west-central waters at times. Looking ahead, yet another set of 
southerly swell may build seas to rough over the same area during
the upcoming weekend.
