Tropical Weather Discussion
NWS National Hurricane Center Miami FL
0405 UTC Tue May 9 2023

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 0000 UTC surface analysis and satellite imagery through
0200 UTC.

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

The monsoon trough extends from 09N78W to 06N93W. The ITCZ 
continues from 06N93W to 04N108W to 06N115W to beyond 03N140W. 
Scattered moderate and isolated strong convection is observed 
from 01N-07N between 88W-105W and from 03N-07N between 112W-135W.

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

Surface ridging along 30N combined with a trough over the Gulf of
California is promoting fresh to strong NW winds within 60 NM of
the Pacific waters west of the Baja peninsula. Elsewhere, winds
are gentle to moderate. Seas are 5-7 ft in the waters west of
Baja, 4-6 ft in the waters south of S Mexico, and 1-3 ft in the 
Gulf of California.

For the forecast, fresh to strong NW to N winds will prevail 
along the Baja offshore waters through Thu night. A brief period 
of strong W winds is expected in the N Gulf of California Tue 
night and Wed morning, as a surface trough moves across the 
region. Gentle to moderate winds and moderate seas will prevail 
elsewhere. Reduced visibilities in haze are possible in the S and
SW Mexican offshore waters due to smoke produced by agricultural
fires. 
 
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...

E gap winds are fresh to strong in the Gulf of Papagayo region,
while fresh N winds are occurring in the Gulf of Panama.
Elsewhere, winds are gentle to moderate. Sea are 6-8 ft in the
Gulf of Papagayo region, 5-7 ft in SW swell in the equatorial
waters, and 4-6 ft elsewhere.

For the forecast, E gap winds will continue to pulse to strong over 
the Gulf of Papagayo region through Tue. Moderate to fresh 
N winds across the Gulf of Panama will decrease Tue. A gentle to
moderate breeze will prevail elsewhere through the end of the 
week. Large SW swell will reach the Galapagos waters Tue before 
diminishing Wed. Reduced visibility in haze is likely from 
Guatemala to Nicaragua due to smoke produced by agricultural 
fires. 

...REMAINDER OF THE AREA...

Surface ridging along 30N combined with low pressure along the 
ITCZ is forcing only moderate to fresh NE trades between 05N-22N 
west of 110W. Elsewhere, winds are gentle to moderate. Seas are 
8-10 ft in long-period SW to S swell and NE wind waves south of 
10N west of 100W, and 5-7 ft elsewhere. 

For the forecast, little change is anticipated in the NE trades
during the next several days. The long-period SW to S swell will
reach up to 20N on Tue, while gradually diminishing. By Thu, the
SW to S swell will drop below 8 ft across the basin, but combined
seas will remain 8-9 ft between 05N-15N west of 120W through Sat.
