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 1800 UTC surface analysis and satellite imagery through 
2200 UTC.
 
...SPECIAL FEATURES...

Recently upgraded Tropical Storm Fausto is centered near 12.4N 
112.7W at 19/2100 UTC, moving west-northwest at 11 kt. Estimated 
minimum central pressure is 1005 mb. Maximum sustained wind speed
is 35 kt with gusts to 45 kt. Peak seas are currently to 12 ft, 
or 4 m. The tropical cyclone's overall cloud pattern is gradually
becoming more consolidated. satellite imagery shows numerous 
moderate to strong convection from 09N to 13N between 112W and 
118W. Scattered moderate convection is seen within 60 nm of the 
center in the SE quadrant. Scattered moderate to isolated strong 
convection is from 14N to 17N between 107W and 112W. Fausto is 
forecast to achieve a west-northwestward or northwestward motion 
at a slightly slower forward speed is expected over the next 
couple of days. Steady to rapid strengthening is forecast during 
the next couple of days, and Fausto is forecast to become a 
hurricane by Mon night. Please read the latest HIGH SEAS FORECAST
issued by the National Hurricane Center at website- 
https://www.nhc.noaa.gov/text/MIAHSFEP2.shtml and the latest 
Six-E NHC Forecast/Advisory and Public Advisory at

Tropical Storm Elida is centered near 23.2N 125.9W at 19/2100 
UTC, moving north-northwest at 9 kt. Estimated minimum central 
pressure is 996 mb. Maximum sustained wind speed is 50 kt with 
gusts to 60 kt. Peak seas are currently around 22 ft, or 6.5 m. 
satellite imagery shows that the earlier observed deep convection
near the center has weakened since this morning. Presently, 
numerous moderate to isolated strong convection is from 22N to
25N between 123W and 126W. Elida is expected to increase in 
forward speed as it turns more northward over the next couple of
days. Weakening is expected during the next couple of days, and 
the cyclone is likely to dissipate by late Wed. Swells generated
by Elida will affect portions of the west coast of the Baja 
California Peninsula and southern California through the early
part of the week. These swells will likely result in life- 
threatening surf and rip current conditions. Please consult 
products from your local weather office. Please read the latest 
HIGH SEAS FORECAST issued by the National Hurricane Center at

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

The monsoon trough axis extends from a 1008 mb low pressure that 
is over northern Colombia westward to across Panama and to 09N92W
to 10N102W and northwestward to just of Tropical Storm Fausto. It 
resumes to the southwest of Fausto at 12N115W, and continues to 
11N125W to 10N134W and to 09N140W. Numerous moderate to strong 
convection is within 240 nm south of the trough between 
129W-140W. Scattered moderate to isolated strong convection is 
within 120 nm south of the trough from 04N to 07N between 
87W-91W, and within 180 nm south of the trough between 123W-127W.
  
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Please refer to the Special Features section for details on
recently upgraded Tropical Storm Fausto, centered about 650 
nautical miles south-southwest of the southern tip of Baja 
California, and on Tropical Storm Elida, centered about 880 
nautical miles west of the southern tip of Baja California.

The earlier fresh to strong north to northeast winds in the Gulf
of Tehuantepec have diminished to moderate to fresh speeds 
this afternoon per a 1632Z Ascat-B pass. Otherwise, rather broad
high pressure is over the offshore waters, with its associated 
gradient generally providing for light to gentle winds. Outer 
associated rough seas from Elida near the far offshore waters 
boundary of Baja California are pulling away from those waters.
Moderate seas dominate elsewhere as seen in satellite altimeter data 
passes. Rough seas associated with recently upgraded Tropical Storm 
Fausto are just encroaching on the extreme southern boundary of 
offshore waters zone that includes the Revillagigedo Islands, with 
seas of 7 to 9 ft in mixed southeast and southwest swell. Slight 
seas remain in the Gulf of California. Winds in the Gulf are light 
to gentle, except with spots of moderate winds in the central and 
northern Gulf sections. Very active convection is present near the 
monsoon trough across much of the offshore waters between 102W and 
113W. This activity reaches to along the coast of Guerrero and 
southern Jalisco. It may contain locally higher winds and seas 
possible near any thunderstorms.

For the forecast, recently upgraded Tropical Storm Fausto will 
move to near 13.1N 114.1W late tonight, to near 14.2N 115.8W Mon 
afternoon, strengthen to a hurricane near 15.4N 117.3W late Mon 
night, move to near 16.3N 118.7W Tue afternoon, and continue to 
pull away from the offshore waters zones through Thu. Associated 
increasing winds and building seas are forecast to impact 
portions of the waters well offshore southwest Mexico to the 
Revillagigedo Islands through Tue night. Fresh to strong 
northerly winds will begin to pulse again in the Gulf of 
Tehuantepec beginning tonight, and through the next several 
days, with locally rough seas at times. In the Gulf of 
California, gentle to moderate winds and slight seas will 
prevail, except for locally fresh winds in the northern part of 
the Gulf through Wed. Northwest winds may freshen nearshore Baja 
California Norte Tue night through Thu as a building ridge 
temporarily tightens there. Looking ahead, a broad area of low 
pressure is forecast to develop well south of Mexico during the 
latter part of the week leading to increasing winds and seas 
possibly impacting portions of the outer offshore waters of 
southern and southwestern Mexico. Environmental conditions appear
conducive for development of the system thereafter, and a 
tropical depression could form while it moves westward to west- 
northwestward across the eastern and central portions of the 
eastern Pacific.

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

Fresh to strong northeast to east winds continue across the Papagayo 
region and downwind to near 09N91W. Moderate to fresh northeast 
winds are near the Gulf of Fonseca. Seas are 6 to 8 ft 
downstream of Papagayo. Moderate or weaker winds and moderate 
seas, primarily in south to southwest swell, dominate the 
remainder of the offshore waters, except slight seas in the 
immediate lee of the Galapagos Islands and near shore western 
Colombia. Very active convection is present near the monsoon 
trough across much of the offshore waters, primarily south and 
southeast of Costa Rica. This activity may contain locally higher
winds and seas possible near thunderstorms.

For the forecast, fresh to strong northeast to east winds along 
with moderate to rough seas will persist across the Papagayo region 
through Fri, with moderate to fresh northeast winds pulsing near the 
Gulf of Fonseca. Gentle to moderate north winds are expected in the 
Gulf of Panama with slight to moderate seas. Moderate or weaker 
winds and moderate seas in southwest swell are expected elsewhere, 
except in the immediate lee of the Galapagos Islands and nearshore 
western Colombia where slight seas are forecast. 

...REMAINDER OF THE AREA...Corrected

Please refer to the Special Features section for details on
recently upgraded Tropical Storm Fausto, centered about 650 
nautical miles south-southwwest of the southern tip of Baja 
California, and on Tropical Storm Elida, centered about 880 
nautical miles west of the southern tip of Baja California.

Both of the above tropical cyclones dominate this part of 
the area. Otherwise, broad ridging prevails both west and east 
of Elida. Winds are mainly moderate or weaker across the 
remainder of the open waters along with moderate seas, except 
moderate to locally fresh in the south-central waters south of 
05N between 105W and 124W along with 7 to 9 ft in southeast to 
south swell over those waters. Very active convection, in large 
clusters, continues to be present near the monsoon trough. It may 
be producing locally higher winds and seas.

For the forecast, Tropical Storm Elida will move to near 24.8N 126.6W
late tonight, to near 27.4N 127.2W Mon afternoon, to near 
30.1N 127.5W late Mon night, and weaken to a remnant low north of
the area near 32.7N 127.5W Tue afternoon and dissipate Thu 
afternoon. Tropical Storm Fausto is forecast to move to near 
13.1N 114.1W late tonight, to near 14.2N 115.8W Mon afternoon, 
strengthen to a hurricane near 15.4N 117.3W late Mon night, then 
reach to near 16.3N 118.7W Tue afternoon, to near 16.7N 120.1W late 
Tue night, and to near 17.0N 121.8W Wed afternoon. Fausto will 
change little in intensity as it moves to the near 17.6N 126.0W Thu 
afternoon. Associated increasing winds and building seas are 
forecast to impact portions of the waters well offshore southwest 
Mexico. Moderate to fresh winds and locally rough seas over the 
south-central waters that follow in behind Fausto will gradually 
spread northward through the early part of the week. Little change 
in marine conditions is expected across the remainder of the open 
waters at least into midweek.

Looking ahead, a broad area of low pressure is forecast to 
develop well south of Mexico during the latter part of the week.
Environmental conditions appear conducive for development of the
system thereafter, and a tropical depression could form while it 
moves westward to west-northwestward across the eastern and central 
portions of the eastern Pacific.
