Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1605 UTC Sun Mar 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 08N77W to 05N87W. The ITCZ
stretches from 05N87W to beyond 04N140W. Scattered moderate
convection is noted along the ITCZ and W of 115W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Fresh to strong northerly winds prevail in the Gulf of
Tehuantepec. These winds are associated with a moderate pressure
gradient between a 1020 mb ridge in the Gulf of America and
lower pressures in the deep tropics. Moderate seas prevail in
these waters. Elsewhere, a broad subtropical ridge located well
northwest of the area supports moderate to fresh northerly winds
and moderate seas in the offshore waters of Baja California. In
the remainder of the basin, moderate or weaker winds and slight
to moderate seas prevail.
For the forecast, the strong northerly winds and rough seas in
the Gulf of Tehuantepec will diminish quickly this morning.
Moderate to fresh NW winds will dominate offshore Baja
California. Moderate to strong SE winds will pulse tonight into
Mon in the Gulf of California as low pressure deepens to the
north. Seas will increase to 8 ft west of Guadalupe Island
tonight and diminish Mon. Otherwise, light to gentle winds will
dominate the basin. The next gap wind event will arrive in the
Gulf of Tehuantepec Mon night, supporting strong to near gale N
winds and rough seas into late this week.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
A broad subtropical ridge centered north of the Caribbean Sea
supports fresh to strong easterly trade winds and moderate seas
across the Gulf of Papagayo, extending downstream to 90W.
Farther east, a tight pressure gradient forces fresh northerly
winds and moderate seas across the Gulf of Panama, extending
south to 03N. Elsewhere, light to gentle winds and moderate seas
are prevalent.
For the forecast, strong NE-E winds will pulse nightly in the
Gulf of Papagayo through much of the week, along with rough
seas. Moderate to fresh N winds will pulse in the Gulf of Panama
during this time. Gentle breezes and moderate seas will prevail
elsewhere.
...REMAINDER OF THE AREA...
The broad high pressure positioned north of the tropical eastern
Pacific waters supports moderate to fresh easterly winds and
moderate seas from the ITCZ to 20N and west of 110W. Farther
east, moderate to fresh easterly winds and moderate seas are
noted north of the ITCZ and east of 105W. Elsewhere, moderate or
weaker winds and moderate seas prevail.
For the forecast, moderate or weaker winds and moderate seas
will generally prevail across the region through the start of
next week. N swell will build just S of 30N from off Baja
California Norte today, leading to rough seas into tonight.
