Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Wed Apr 17 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
0830 UTC.

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

A trough extends from Panama near 08N78W to 06N95W. The ITCZ 
continues from 06N95W to 05N115W to beyond 08N135W to 08N140W. 
Scattered moderate convection is noted from 05N to 07N between 
133W and 135W. 

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

Moderate NW winds persists along the coast and offshore waters 
of Baja California, between weak high pressure west of the area
and lower pressure over central Mexico. NW swell moving through 
the regional waters is producing seas of 6 to 8 ft to the 
Revillagigedo Islands. Moderate winds and seas persist elsewhere.

For the forecast, NW swell of 8 ft off Baja California to the Revillagigedo
Islands will gradually subside through late today. Gentle to moderate
winds and moderate seas will persist elsewhere through Sat. Looking
ahead, fresh NW winds and building swell will follow a trough 
into the waters near Guadalupe Island off Baja California Norte 
by Sun. 

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

Moderate to locally fresh NE to E gap winds prevail across the Papagayo
region and Nicaragua waters to 90W, with 5 to 7 ft seas. Light 
to gentle winds and moderate seas of 3 to 6 ft in SW swell are 
noted elsewhere.

For the forecast, fresh gap winds pulsing across the Gulf of 
Papagayo will diminish later today. Gentle to moderate breezes 
will persist elsewhere through Sun, with mostly 4 to 6 ft 
combined seas primarily in SW swell.

...REMAINDER OF THE AREA...

Recent scatterometer satellite data indicated a broad of mostly
fresh to locally strong trade winds from 08N to 18N between 125W
and 135W. These winds are active between a 1008 mb low pressure
area along the ITCZ near 133W, and broad high pressure north of
20N. Combined seas are 8 to 11 ft in this area, in a mix of NW
swell, S swell, and shorter-period easterly waves resulting from
the trade wind flow. A broader area of mixed swell extends
farther east of this area to about 110W. Gentle to moderate
breezes and moderate seas are evident elsewhere.

For the forecast, wave heights will subside across the region
through Fri, although an area of 8 ft seas will persist from 08N
to 12N west of 130W due to fresh trade winds and lingering 
swell through Sun.
