1605 UTC Sun Aug 14 2022

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
1530 UTC.


Tropical Depression Ten-E is centered near 18.3N 113.1W at
14/1500 UTC moving WNW at 4 kt. Estimated minimum central
pressure is 1007 mb. Maximum sustained wind speed is 30 kt with
gusts to 40 kt. The center of Ten-E remains exposed under strong
easterly shear keeping numerous showers and thunderstorms within
60 and 90 nm to the west of the center. Seas are ranging between
8-10 ft in the northern semicircle of the system, just west of 
Socorro Island.

Please read the latest NHC Public Advisory at and Forecast/
Advisory at for
more details.


A tropical wave extends along 86W north of 09N, moving west at 
around 10 kt. Scattered showers and tstms associated with this 
wave are from 05N to 13N between 84W and 90W. 

A tropical wave extends along 107W from 05N to 18N, moving west 
at 10 kt. Scattered moderate convection is noted across the
northern portion of the wave mainly N of 15N.


Segments of the monsoon trough extend from 11N86W to 11N103W, 
and from 15N114W to 08N140W. Scattered moderate convection is 
evident from 04N to 14N and E of 91W, and from 07N to 15N between
122W and 140W.


Refer to the Special Features section for details on T.D. Ten-E.

Ship observations and recent scatterometer satellite pass 
indicted moderate NW winds off Baja California north of Cabo San 
Lazaro, with fresh winds possibly funneling along the coast. Seas
are 5 to 6 ft north of Cabo San Lazaro in NW swell. Farther 
south, fresh to strong winds are noted between Socorro Island and
Clarion Island related to Ten-E, with seas estimated to be as 
high as 10 ft in this area. Light to gentle breezes are noted 
elsewhere, with 3 to 5 ft seas in open waters in mostly SW swell 
south of 20N, and NW to N swell north of 20N. Light SE winds and 
slight seas are noted in the Gulf of California. 

For the forecast, Tropical Depression Ten-E will move to 18.5N 
113.6W this evening, become a remnant low and move to 18.5N 
114.2W Mon morning, 18.3N 114.8W Mon evening, 18.1N 115.3W Tue 
morning, 18.0N 116.0W Tue evening, and 18.0N 117.0W Wed morning. 
Ten-E will dissipate early Thu. Light to gentle variable winds 
and slight to moderate seas are expected elsewhere.


A cluster of showers and thunderstorms prevails west of Costa 
Rica as a tropical wave interacts with the monsoon trough in the
area. Fresh winds and seas to 6 ft are expected within this 
convective activity. Light to gentle breezes persist north of 
05N, with 3 to 5 ft seas. Gentle to moderate SW winds and 4 to 6 
ft seas in SW swell are noted south of 05N. 

For the forecast, moderate SW winds will prevail across the 
offshore waters between Ecuador and the Galapagos Island through 
the forecast period. Seas will build in SW swell in this region 
tonight and then will continue to spread northward towards the 
Central America offshore waters south of 05N through the week. 
Light to gentle variable winds and moderate seas will prevail 
across the northern Central America offshore waters through mid- 


Refer to the Special Features section above for details on T.D. 

Elsewhere, a broad surface ridge dominates the waters north of 
the monsoon trough and west of 115W. Moderate to fresh NE to E 
winds are north of 20N and west of 130W, and between the monsoon
trough and 20N west of 120W where seas are 5-7 ft. Mainly gentle
winds are elsewhere N of the monsoon trough between 110W and 
120W. Moderate S to SW winds are S of the monsoon trough with 
seas to 6 ft.

For the forecast, aside from T.D. Ten-E, no major changes are 
expected elsewhere through the middle of next week.
