Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Fri Aug 30 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
0900 UTC.

...TROPICAL WAVES...

A tropical wave is near 115W from 07N to 20N, moving westward at
10-15 kt. No significant convection is noted near this tropical 
wave.

A tropical wave is along 131W from 07N to 20N, moving westward 
at 10-15 kt. Scattered moderate convection are noted from 10N to
12N between 125W and 135W.

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

The monsoon trough extends from 10N85W to 09N93W to 13N105W to
10N140W. Aside from the convection associated with the tropical 
wave described above, scattered moderate to isolated strong 
convection is noted from 05N to 09N between 80W and 85W, and 
from 10N to 15N between 95W and 100W.
 
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Recent scatterometer satellite data indicated moderate to fresh 
winds off the coast of Baja California between Cabo San Lazaro 
and Punta Eugenia. Concurrent altimeter data showed 5 to 6 ft 
seas in this area. These winds are funneling between the coast 
and the subtropical ridge west of the region. Moderate S to SW 
gap winds are active over the northern Gulf of California between
the ridge and low pressure over the lower Colorado River Valley.
Light to gentle breezes and 3 to 5 ft seas are noted elsewhere.

For the forecast, a surface ridge will continue to dominate the
offshore forecast waters of Baja California through mid week,
supporting moderate NW winds and moderate seas north of Cabo San
Lazaro into mid week, and light to gentle breezes elsewhere. 

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

Scattered showers and thunderstorms are ongoing off western 
Panama and Costa Rica offshore waters, south of the monsoon 
trough. In the Papagayo region, moderate NE winds and moderate 
seas prevail. Light to gentle winds prevail elsewhere across the
area north of the monsoon trough with slight to moderate seas. 
South of the monsoon trough, moderate to fresh S to SW winds are 
ongoing with moderate seas to 7 ft, highest east of the Galapagos
Islands.

For the forecast, gentle to moderate winds and moderate seas 
will persist across the region into mid week.

...REMAINDER OF THE AREA...

A surface trough, the remnants of Hector, is analyzed along 138W
from 15N to 20N. Fresh to strong winds persist in the vicinity 
of the trough, with seas 8 to 10 ft, as noted in recent
scatterometer and altimeter satellite data.

A surface ridge dominates most of the waters north of 20N and
west of 110W. Gentle to moderate anticyclonic flow and 5-6 ft 
seas prevail elsewhere across the subtropical waters under the 
influence of the ridge. Moderate to fresh southerly winds are 
noted S of the monsoon trough.
 
For the forecast, the trough that is the remnants Hector will 
move west of 140W through early today. A surface ridge will 
build across most of the forecast waters north of 15N and west of
110W toward the end of the week. Elsewhere, southerly winds 
south of the monsoon trough to the Equator will remain moderate 
to fresh through the week, with seas of 5 to 7 ft.
