NWS National Hurricane Center Miami FL
1005 UTC Wed Nov 27 2024

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
0745 UTC.

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

The monsoon trough extends from 09N84W to 06N93W to 08N103W. The
ITCZ extends from 08N105W to beyond 10N140W. Scattered moderate
convection has developed from 07N to 10N between 113W and 132W.

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

Strong to near gale-force gap winds are ongoing across the Gulf 
of Tehuantepec due to building high pressure northeast of the 
area. A ridge farther north is supporting mainly gentle breezes,
with moderate seas, elsewhere.

For the forecast, strong to near-gale force gap winds will pulse
across the Gulf of Tehuantepec today, accompanied by rough to 
very rough seas. This is associated with high pressure building 
northeast of the area. These winds and seas will diminish 
tonight as the high pressure weakens and shifts eastward,. 
Looking ahead, similar conditions will develop in the Gulf of 
Tehuantepec Fri, then prevail through the weekend, with winds 
briefly reaching minimal gale force Fri night. Farther north, 
fresh NW winds develop across the Gulf of California Thu and 
Fri high pressure builds in from the NW. 

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

Mainly gentle winds and seas of 4 to 6 ft dominate N of the 
monsoon trough. S of the monsoon trough, gentle to moderate SW to
W winds and seas of 4 to 6 ft prevail. 

For the forecast, light to gentle winds are expected north of the
monsoon trough, except for occasional pulses of moderate gap 
winds in the Papagayo region. Gentle to moderate SW to W winds 
will prevail south of the monsoon trough. NE swell from gap winds
in the Gulf of Tehuantepec will support combined seas to 9 ft 
off Guatemala today. Elsewhere, cross equatorial SW swell up to 
7 ft will impact the offshore waters from Ecuador to western 
Panama into Thu, then gradually subside thereafter. 

...REMAINDER OF THE AREA...

Weak ridging extends across the waters north of 15N, anchored by
1020 mb high pressure near 29N121W. Moderate SW winds are noted 
over the waters north of 25N and west of 135W, between the high 
pressure and the low pressure to the northwest. Seas are 6 to 7 
ft in this area. N of the ITCZ, a band of moderate trades prevail
W of 110W and S of 16N. To the S of the ITCZ, moderate SE winds
with dominate. Seas average 5 to 7 ft, with some localized 8 ft
seas along the ITCZ. 

For the forecast, low pressure near 31N143W will drift to the 
east, dragging a cold front across the waters north of 25N and 
west of 120W through Fri, before lifting northward. To the south,
moderate to locally fresh trade winds will persist west of 110W
into the weekend.
