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
0850 UTC.
...SPECIAL FEATURES...
Gulf of Tehuantepec Gale Warning: Building ridging over NE
Mexico supports strong to gale-force northerly winds and rough
seas to 13 ft across the Gulf of Tehuantepec. Gale force winds
will continue through early this morning. Gusty winds to near
storm force may occur. Seas generated from this gap wind event
will spread well away from the Tehuantepec area, with seas 8 ft
or greater reaching as far south as 10N and 100W this morning.
Winds and seas will quickly diminish late this morning. Please
read the latest High Seas Forecast issued by the National
Hurricane Center at website:
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml for more details.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
A surface trough extends from 07N79W to 04N100W. The ITCZ
stretches from 04N100W to 03N120W to beyond 00N140W. A second
ITCZ is located south the discussion area. Scattered moderate
convection is observed from 03N to 06N between 83W and 99W, and
from 04N to 10N between 115W and 128W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please refer to the Special Features section for details on the
Gulf of Tehuantepec Gale Warning.
Aside from the Gale Warning in the Gulf of Tehuantepec, a weak
NW to SE ridge extends along the outer offshore waters boundary
with troughing over central Mexico. This pattern supports
moderate to locally fresh NW-N winds from Cabo San Lazaro
northward offshore Baja California. Winds are mainly light to
gentle across the remainder of the waters away from the Gulf of
Tehuantepec, including in the Gulf of California. Seas are mainly
5-6 ft away from the Gulf of Tehuantepec in a mix of S and NW
swells, with seas 3 ft or less in the Gulf of California away
from the entrance.
For the forecast, other than the Gale Warning in the Gulf of
Tehuantepec, winds will pulse there to fresh to strong once the
gale ends on Tue. Moderate to locally fresh NW winds and
moderate seas are expected off Baja California through Thu night.
Winds may pulse to strong N of Punta Eugenia at times through Thu
evening. Moderate to fresh SW winds may develop in the northern
Gulf of California Fri night ahead of a cold front approaching
Baja California Norte, then to fresh to strong Sat night. Winds
will be moderate or weaker elsewhere through the next several
days. Little change in seas is forecast through the week.
....OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
A building ridge over the NW Gulf of America forces fresh easterly
winds across the Gulf of Papagayo region. Seas in this region
are around 5 ft. Farther east, moderate N-NE winds and 3-4 ft
seas are present in the Gulf of Panama. Light to gentle winds and
moderate seas dominate the remainder of the offshore forecast
waters.
For the forecast, fresh to locally strong gap winds are expected
during the nighttime and early morning hours in the Papagayo
region and downwind to about 90W through the forecast period.
Moderate to locally fresh northerly winds are forecast in the
Gulf of Panama through the forecast period. The ongoing gap wind
event in the Tehuantepec region will produce seas to 9 ft in the
far offshore waters of Guatemala through today. Light to gentle
winds and moderate seas will prevail elsewhere.
...REMAINDER OF THE AREA...
A week cold front extends from 30N13W to 23.5N138W. Seas to 9 ft
follow the front. Father south, a deep upper level trough
continues to produce abundant cloudiness and some showers over
the W-central and northern waters, extending from S of the
Hawaiian Islands northeastward to Baja California and into the SW
United States. Elsewhere at the surface, a weak high pressure
system over the northern waters with 1022 mb high pressure
centered near 32N126W dominates the remainder of the basin.
Moderate to locally fresh easterly winds are occurring from
roughly 09N to 16N and W of 120W, highest near the convection
along the ITCZ which is described above. Seas in these waters
remain at 6 to 8 ft. Elsewhere, moderate or weaker winds and
moderate seas are prevalent.
For the forecast, the cold front will continue to move SE as it
weakens, and seas behind the front will subside later today.
Continuing high pressure will support moderate to locally fresh
easterly winds and moderate to locally rough seas across the
trade wind zone through the forecast period, supporting seas to
around 7 ft. Seas will build to around 8 ft in NE swell from a
Gulf of Tehuantepec gale force gap wind event to near 10N100W
today through tonight. Moderate to fresh winds will accompany
those seas. Seas may build to around 8 ft in southerly swell near
03.4S by the end of the week.
