1605 UTC Sun Aug 30 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.
...SPECIAL FEATURES...
Hurricane Karina is centered near 17.3N 122.1W at 30/1500 UTC,
moving west-northwest at 8 kt. Estimated minimum central
pressure is 980 mb. Maximum sustained wind speed is 70 kt with
gusts to 85 kt. Peak seas are around 33 ft (10 m). Numerous
moderate to scattered strong convection is noted within 120 nm
of the center. Karina is moving toward the west- northwest. A
slower westward to west-northwestward motion is expected during
the next few days. Steady to rapid strengthening seems likely,
and Karina is forecast to become a major hurricane in a day or
so. Swells generated by Karina will affect portions of the coast
of southwest Mexico and the Baja California Peninsula for the
next couple of days. These swells are likely to cause life-
threatening surf and rip current conditions. Please consult
products from your local weather office.

Hurricane Center at website -

Tropical Storm Lowell is just west of area centered near 13.3N
140.4W at 30/1500 UTC, moving west at 11 kt. Estimated minimum
central pressure is 1000 mb. Maximum sustained wind speed is 45
kt with gusts to 55 kt. Peak seas are currently around 13 ft (4
m). Numerous moderate to scattered strong convection is within
180 nm W semicircle. Lowell is moving toward the west near 13 mph
(20 km/h), and a general westward motion is expected during the
next two to three days. Gradual strengthening is expected during
the next few days, and Lowell could become a hurricane by Monday
or Monday night.

Well Offshore of Southwestern Mexico:
An area of disturbed weather, associated with a tropical wave, is
located well to the south of southwestern Mexico. This system is
expected to continue to move west-northwestward to northwestward
at 10 to 15 mph. Environmental conditions appear favorable for
gradual development of this system, and a tropical depression is
likely to form during the early to middle part of next week.
This system has a medium chance of tropical cyclone formation
through 48 hours, and a high chance through 7 days. Refer to the
latest NHC Tropical Weather Outlook at www.hurricanes.gov for
more details.
...TROPICAL WAVES...
The axis of a tropical wave is along 88W north of 05N, moving
west at 10 to 15 kt. Scattered moderate convection is active
from 10N to 12N between 88W and 96W.
The axis of a tropical wave is along 107W from 05N to 17N, moving
quickly westward at around 20 kt. Numerous moderate to scattered
strong convection is noted from 07N to 14N between 100W and
110W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from 09N84W to 09N90W to 08N90W to
11N107W to 10N110W. In addition to the convection near Karina,
Lowell and the tropical waves, scattered moderate to isolated
strong convection is evident N of 04N E of 81W to the coast of
Colombia. Part of this convective activity is over the Gulf of
Panama. Similar convection is also found from 02N to 10N W of
115W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please see the Special Features section for more information on
Hurricane Karina, and an area of disturbed weather with the
potential of tropical cyclone formation.
While the main impacts of Karina remain west of the Mexican
offshore waters, strong to near gale force winds and rough to
very rough seas on the far northeast periphery of Karina are
reaching the Revillagigedo Islands. Outer rainbands associated
with the cyclone's circulation are also moving across the
islands. Fresh to strong N gap winds continue to blow across
Tehuantepec region and downwind to near 14N. Gentle to locally
moderate southerly winds and slight seas dominate the Gulf of
California except the northern part where fresh to locally strong
winds and moderate seas are noted. Gentle to moderate winds and
moderate seas are noted elsewhere.
For the forecast, Hurricane Karina Karina will move to 17.5N
123.5W this evening, 17.6N 125.1W Mon morning, 17.8N 126.9W Mon
evening, 18.1N 128.7W Tue morning, 18.6N 130.3W Tue evening, and
19.1N 131.9W Wed morning. Karina will change little in intensity
as it moves to near 20.0N 135.1W early Thu. The fresh SE winds
impacting the Revillagigedo Islands, particularly Clarion Island,
on the far eastern periphery of Hurricane Karina, will diminish
through late today as the storm moves farther west. Associated
rough to very rough seas will gradually subside from east to west
across the islands by tonight. Fresh to strong northerly gap
winds and occasional rough seas will continue to pulse in the
Gulf of Tehuantepec through this morning. Fresh to strong
southerly winds are expected across the northern and central Gulf
of California through tonight into Mon. Looking ahead, an area
of disturbed weather, associated with a tropical wave, is located
well to the south of southwestern Mexico. This system is
expected to continue to move west-northwestward to northwestward
at 10 to 15 mph. Environmental conditions appear favorable for
gradual development of this system, and a tropical depression is
likely to form during the early to middle part of next week.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Fresh to strong easterly gap winds persist in the Gulf of Papagayo
and downwind to near 10N90W, with 6 to 8 ft seas. Gentle to
moderate winds and 4 to 6 ft seas are noted elsewhere.
For the forecast, fresh to strong NE to E gap winds will continue to
pulse in the Gulf of Papagayo area through the weekend into
early next week, then weakening slightly thereafter. Associated
moderate to fresh winds will extend well downwind to the outer
offshore waters of El Salvador and Guatemala. Southerly winds
may freshen south of the monsoon trough this weekend into early
next week. Winds will be moderate or weaker elsewhere with
mainly moderate seas. Convection will remain active near the
monsoon trough.
...REMAINDER OF THE AREA...
Please see the Special Features section for more information
about Hurricane Karina, Tropical Storm Lowell, currently located
just west of the forecast area, and an area of disturbed weather
located well offshore of Southwestern Mexico with the potential
of tropical cyclone formation.
A trough, associated with the remnant low of Post-Tropical cyclone
Iselle, extends from 27N135W to 20N139W. Fresh to strong NE
winds and seas of 7 to 9 ft are occurring near the northern end
of the trough axis and mainly 25N to 28N W of 137W . Elsewhere,
mainly moderate or weaker winds dominate the remainder of the
open waters both north and south of the monsoon trough away from
the two tropical cyclones and the aforementioned trough. Rough
seas generated by Karina cover the waters 10N to 23N between
113W and 127W. Seas are mainly moderate across the remainder of
the open waters.
For the forecast, Hurricane Karina Karina will move to 17.5N 123.5W
this evening, 17.6N 125.1W Mon morning, 17.8N 126.9W Mon evening,
18.1N 128.7W Tue morning, 18.6N 130.3W Tue evening, and 19.1N
131.9W Wed morning. Karina will change little in intensity as it
moves to near 20.0N 135.1W early Thu. Tropical Storm Lowell
will be W of area near 13.3N 142.0W this afternoon. The associated
winds and seas will also move W of area by tonight. Seas generated
by Karina will continue to propagate across a large part of the
forecast region early this week.
