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
0300 UTC.
...SPECIAL FEATURES...
Tropical Storm Marie is centered near 24.2N 123.2W at 07/0300
UTC, moving northwest at 5 kt. Estimated minimum central
pressure is 983 mb. Maximum sustained wind speed is 60 kt with
gusts to 75 kt. Peak seas are to near 28 ft. Numerous moderate
isolated strong convection is within 120 nm SE quadrant.
Scattered moderate convection is within 60 nm elsewhere of
center, except 90 nm SW quadrant. Steady weakening is expected
to continue for the next several days, and Marie is forecast to
become a post-tropical remnant low Tuesday night or early
Wednesday. Swells generated by Marie will continue to affect
portions of the coast of the Baja California Peninsula and
southern California for the next couple of days. These swells are
likely to cause life-threatening surf and rip current
conditions. Please consult products from your local weather
office. A depiction of rip current risk for the United States can
be found at:

Please read the latest High Seas Forecast issued by the National
Hurricane Center at website -

Marie NHC Forecast/Advisory and Public Advisory at
www.hurricanes.gov for more details.
...TROPICAL WAVES...
A tropical wave has its axis along 108W from 04N to 19N, moving
westward at 5 to 10 kt. Scattered showers are noted along the
wave axis.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough extends from 11N86W to 09N140W. Scattered to
numerous moderate to strong convection is within 500 nm S of the
trough.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please see the Special Features section for information on
T.S. Marie centered about 480 nm west-southwest of Punta
Eugenia, Mexico.
Fresh to strong southeast to south winds on the outer fringe
of Hurricane Marie are over the outer offshore waters from
Punta Eugenia to Cabo San Lazaro. Seas within these winds are
8 to 12 ft in southwest to west swell. Moderate or weaker winds
and rough seas in southwest to west swell are over the rest of
the Baja California offshore waters. Over the remainder of the
Mexican offshore waters, moderate or lighter winds and slight to
moderate seas are prevalent.
For the forecast, Tropical Storm Marie will move to 24.6N 124.0W
Mon morning, 25.1N 125.3W Mon evening, 26.0N 126.5W Tue morning,
27.4N 127.5W Tue evening, weaken to a remnant low near 29.4N
128.5W Wed morning, and 31.6N 129.7W Wed evening. Marie will
change little in intensity as it moves to 35.3N 133.3W by late
Thu. A trough of low pressure located several hundred nautical
miles south-southwest of the coast of southwestern Mexico is
producing disorganized showers and thunderstorms. Gradual
development of this system is possible, and a tropical depression
could form during the middle or latter portions of this week
while the system moves generally west-northwestward.
...OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA,
AND WITHIN 750 NM OF ECUADOR...
Earlier satellite Ascat data captured fresh northeast to east
winds in the Gulf of Papagayo region. Seas are 5 to 7 ft with
these winds. Elsewhere, moderate or weaker winds and slight to
moderate seas prevail. Scattered showers and thunderstorms are
affecting much of the offshore waters of Central America and
Colombia, some of which may be accompanied by gusty winds and
higher seas.
For the forecast, high pressure north of the area will support
moderate to fresh easterly winds and moderate seas across the
Gulf of Papagayo region through the next several days. Building
ridging by the middle of the week will result in strong gap
winds and rough seas there, with winds possibly reaching near
gale Wed night. Meanwhile, moderate to fresh southerly winds are
expected across the waters between Ecuador and the Galapagos
Tue through Wed. Moderate or lighter winds are expected
elsewhere.
...REMAINDER OF THE AREA...
Please see the Special Features section for information about
T.S. Marie located about 480 nm west-southwest of Punta Eugenia,
Mexico.
Outside from marine impacts attributed to T.S. Marie over the
northeast portion of this part of the region, fresh cyclonic
winds and rough seas persist from 21N to 28N and west of 138W
associated with the outer eastern quadrant of the remnants of
Karina that continues to move farther away from the eastern
Pacific basin. Elsewhere, moderate or weaker winds with seas of 5
to 7 ft are prevalent across the remainder of the tropical
eastern Pacific.
For the forecast, Tropical Storm Marie will move to 24.6N 124.0W
Mon morning, 25.1N 125.3W Mon evening, 26.0N 126.5W Tue morning,
27.4N 127.5W Tue evening, weaken to a remnant low near 29.4N
128.5W Wed morning, and 31.6N 129.7W Wed evening. Marie will
change little in intensity as it moves to 35.3N 133.3W by late
Thu.
Cross equatorial swell will produce seas to 8 ft in the southern
waters west of about 100W during much of the week. A trough of
low pressure located several hundred nautical miles south-
southwest of the coast of southwestern Mexico is producing
disorganized showers and thunderstorms. Gradual development of
this system is possible, and a tropical depression could form
during the middle or latter portions of this week while the
system moves generally west-northwestward.
