radar, and meteorological analysis.

Based on 0000 UTC surface analysis and satellite imagery through
0100 UTC.

...SPECIAL FEATURES...

Recently upgraded Tropical Depression Six-E: centered near 11.3N
109.1W at 19/0300 UTC, moving west-northwest at 10 kt. Estimated
minimum central pressure is 1008 mb. Maximum sustained wind 
speed is 30 kt with gusts to 40 kt. Peak seas are currently 10 to
11 ft or around 3.5 m. Numerous moderate isolated strong 
convection is noted from 08N to 17N between 105W and 115W. 
Associated winds are currently 20 to 30 kt with seas of 8 to 11 
ft. The depression is moving toward the west-northwest, and this
general motion is expected to continue for the next two to three
days. Steady to rapid strengthening is forecast during the next
few days. The depression is forecast to become a tropical storm 
on Sun and become a hurricane by Mon night or Tue. 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 www.hurricanes.gov for more details.

Tropical Storm Elida: centered near 20.6N 124.8W at 19/0300 UTC,
moving north-northwest at 11 kt. Estimated minimum central 
pressure is 993 mb. Maximum sustained wind speed is 55 kt with 
gusts to 65 kt. peak seas are currently around 26 ft or 8 m. 
Numerous moderate convection covers much of the waters from 17N 
to 27N between 122W and 129W, with isolated strong from 19N to 
20.5N between 124W and 126W. Elida is moving toward the north-
northwest. A gradual increase in forward speed is expected over 
the next couple of days as the system turns northward. Steady 
weakening is expected during the next couple of days as Elida 
moves over progressively cooler waters. Elida is forecast to 
become a remnant low by early Tue and dissipate by late Wed.
Swells generated by Elida will affect portions of the west coast
of the Baja California Peninsula and southern California through
early next 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 extends from 1006 mb low pressure over
northern Colombia at 10N74.5W to 10N86W to 08N98W to Tropical
Depression Six-E near 11N108.5W to 15N116W, then resumes south- 
southeast of Elida from 16N119W to 09N140W. Other than the 
convection discussion above and associated with Elida and Six-E,
numerous moderate to strong convection is noted from 00N to 14N 
between 77W and 90W, and from 03N to 13N between 90W and 104W. 
Scattered moderate to strong convection is noted within 240 nm 
south- southeast of the monsoon trough between 119W and 135W.
 
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Please refer to the Special Features section for details on
Tropical Storm Elida, centered about 843 nautical miles west of 
the southern tip of Baja California, and on recently upgraded 
Tropical Depression Six-E, centered about 700 nautical miles 
south of the southern tip of Baja California.

Fresh to strong N to NE winds and moderate seas are in the Gulf 
of Tehuantepec. Otherwise, rather broad high pressure is over 
the offshore waters, with moderate or weaker winds. Outer
associated rough seas from Elida are near the far outer offshore
waters boundary of Baja California and are finally pulling away.
Moderate seas dominate elsewhere, with rough seas associated with
recently upgraded Tropical Depression Six-E just beyond the 
outer offshore waters of southwestern Mexico. Seas are slight in 
the Gulf of California. Very active convection is present near 
the monsoon trough across much of the offshore waters south of 
14N, with locally higher winds and seas possible near 
thunderstorms.

For the forecast, seas generated by Elida will finally subside to
less than 8 ft by Sun afternoon. Meanwhile, recently upgraded
Tropical Storm Six-E will strengthen to a tropical storm near 
11.9N 110.7W Sun morning, move to 12.6N 112.9W Sun evening, 13.4N
114.7W Mon morning, strengthen to a hurricane near 14.6N 116.4W 
Mon evening, 15.4N 117.9W Tue morning, and 16.0N 119.4W Tue 
evening. Six-E will change little in intensity as it moves to 16.7N
122.8W late Wed. Associated increasing winds and building seas
are forecast to impact portions of the waters well offshore 
southwest Mexico to the Revillagigedo Islands this weekend into 
early next week. Fresh to strong northerly winds will continue to
pulse in the Gulf of Tehuantepec 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 Gulf at times. Winds may 
freshen nearshore Baja California Norte midweek as the gradient 
temporarily tightens there. Looking ahead, low pressure may 
develop well south of Mexico during the middle to latter part of 
next week and increasing winds and seas may impact portions of 
the outer offshore waters of southern and southwestern Mexico by 
the end of next week.

...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 09N92W. Moderate to fresh NE winds are 
near the Gulf of Fonseca. Seas are 6 to 9 ft downstream of Papagayo. 
Moderate to locally fresh N to NE winds are in the Gulf of
Panama. 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, with locally higher winds and seas possible near 
thunderstorms.

For the forecast, fresh to strong NE to E winds and moderate to 
rough seas will persist across the Papagayo region to 09N92W 
through at least the middle of the week, with moderate to fresh 
NE winds pulsing near the Gulf of Fonseca at times. Moderate or 
weaker winds and moderate seas in SW swell are expected 
elsewhere, except in the immediate lee of the Galapagos Islands 
and nearshore western Colombia where slight seas are forecast.
Looking ahead, low pressure may develop well south of Mexico 
during the middle to latter part of next week and increasing
winds and seas may impact portions of the outer offshore waters
of Guatemala and El Salvador.

...REMAINDER OF THE AREA...

Please refer to the Special Features section for details on
Tropical Storm Elida, centered about 843 nautical miles west of 
the southern tip of Baja California, and on recently upgraded 
Tropical Depression Six-E, centered about 700 nautical miles 
south of the southern tip of Baja California.

Both of the above systems dominate the open waters, as well as
another area of disturbed with and associated fresh to strong
winds and locally rough seas near 07N95W. 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 100W and 130W, along 
with 6 to 9 ft seas. Very active convection is present near the
monsoon trough, concentrated near all three significant features
with locally higher winds and seas possible.

For the forecast, Tropical Storm Elida will move to 21.9N 125.7W
Sun morning, 24.0N 126.6W Sun evening, 26.4N 127.3W Mon morning,
29.0N 127.7W Mon evening, weaken to a remnant low north of the
discussion waters near 31.4N 127.8W Tue morning, and then move to 
33.9N 127.8W Tue evening. Elida will dissipate late Wed. Meanwhile,
recently upgraded Tropical Storm Six-E will strengthen to a 
tropical storm near 11.9N 110.7W Sun morning, move to 12.6N 
112.9W Sun evening, 13.4N 114.7W Mon morning, strengthen to a 
hurricane near 14.6N 116.4W Mon evening, 15.4N 117.9W Tue 
morning, and 16.0N 119.4W Tue evening. Six-E will change little 
in intensity as it moves to 16.7N 122.8W late Wed. Associated 
increasing winds and building seas are forecast to impact 
portions of the waters well offshore southwest Mexico to the 
Revillagigedo Islands this weekend into early next week. Moderate
to fresh winds and locally rough seas over the south- central 
waters will gradually spread northward in the wake of Elida and 
the wake of Six-E into early next week. Little change in marine 
conditions is expected across the remainder of the open waters 
going into the early part of the week.

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