Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Jul 3 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.

...SPECIAL FEATURES...

Gale warning: Post-Tropical Cyclone Douglas is centered near 
18.8N 127.6W at 03/0300 UTC, moving north-northwest at 6 kt. 
Estimated minimum central pressure is 1003 mb. Maximum sustained 
wind speed is 35 kt with gusts to 45 kt. Seas of up to 4.0 m 
extend up to 90 nm from the center. Douglas is no longer a 
tropical storm, and showers and thunderstorms are diminishing 
around Douglas as the storm moves over cooler waters. However, a 
recent scatterometer satellite pass showed tropical storm force 
winds persisting within 150 nm in the norther quadrant of the 
center. Therefore, a gale warning remains in effect for the 
remaining overnight period. Douglas is predicted to gradually 
weaken this weekend and then open into a trough and dissipate by 
Sunday.

Hurricane Center at website - https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml

...TROPICAL WAVES...

A tropical wave is along 89W, south of 20N in the NW Caribbean, 
moving west at 15 to 20 kt. Associated convection is described 
below in the Intertropical Convergence Zone/Monsoon Trough 
section.

A tropical wave is analyzed along 100W, south of 15N, moving 
west at 5-10 kt. Associated convection is also described below 
in the Intertropical Convergence Zone/Monsoon Trough section.

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

The monsoon trough extends from 10N84W to 05N100W to 10N125W to
11N135W. The ITCZ extends from 11N135W to beyond 10N140W. 
Scattered moderate isolated strong convection is noted from 05N 
to 14N east of 105W.

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

Fresh to strong gap winds with locally rough seas are pulsing 
across the Gulf of Tehuantepec, between high pressure north of 
the region and lower pressure over the tropics. Associated seas 
are reaching 8 ft in the plume of these gap winds. Farther north,
a ridge off Baja California will maintain gentle to moderate 
breezes, with 4-6 ft seas off Baja. Gentle breezes and slight 
seas are noted elsewhere.

For the forecast, the fresh to strong gap winds with locally 
rough seas will pulse across the Gulf of Tehuantepec this 
morning, then diminish. Farther north, the ridge off Baja 
California will maintain gentle to moderate breezes through Sat, 
becoming moderate to occasionally fresh near the coast of Baja 
California starting Sun as the high pressure builds. Looking 
ahead, large SW swell may reach the waters off southern Mexico 
early next week. 

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

Fresh to strong NE gap winds continue to dominate the Papagayo 
region and extend offshore to near 90W. Seas are 6 to 8 ft across
this area. Gentle to moderate SW breezes are noted elsewhere. 
Cross- equatorial SW swell to 8 ft dominate waters S of 02N 
between the Galapagos Islands and Ecuador, with 4-6 ft seas 
elsewhere. Scattered to numerous strong convection continues 
across the waters N of 05N from Colombia to offshore of 
Guatemala, producing strong gusty winds and locally rough seas.

For the forecast, fresh to strong NE to E gap winds will pulse 
in the Papagayo region into early next week, leading to 
occasional rough seas. Cross- equatorial southerly swell will 
dominate area seas through the weekend and keep seas moderate to 
the S of 05N through Mon, increasing to near 8 ft off Ecuador and
the Galapagos Sun night through Tue. Large SW swell may also 
reach the waters off northern Central America early next week.

...REMAINDER OF THE AREA...

Please see the Special Features section on the gale warning
associated with Post-Tropical Cyclone Douglas. Fresh to strong 
winds and rough seas extend 360 to 480 nm from the center of 
Douglas. Moderate to fresh NE winds and 6-7 ft seas are noted 
elsewhere north of 15N and west of 120W. Farther east, fresh 
winds and locally rough seas accompany the tropical wave along 
100W. Mostly gentle breezes and 4-6 ft in mixed swell are noted 
elsewhere. 

For the forecast, winds and seas near Douglas will diminish
through Sun night as the remnant low opens into a trough. The 
ridge will then drift southwestward and generally persist across
the region through early next week, supporting moderate to fresh
trade winds farther south into the tropics. Looking ahead, weak
low pressure may form about 360 nm south of the Revillagigedo
Islands by Sun night. Environmental conditions could 
support some gradual development of this system while it moves 
generally westward at 10-15 kt through the early part of next
week, although chances of development at this time are low.
