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
1545 UTC.
...SPECIAL FEATURES...Corrected
Hurricane Marie is centered near 23.5N 122.5W, or about 700 nm
west of the southern tip of Baja California at 06/1500 UTC,
moving northwest at 8 kt. Estimated minimum central pressure is
977 mb. Maximum sustained wind speed is 70 kt with gusts to 85
kt. Peak seas are to near 29 ft. Latest satellite imagery reveals
that Marie has become less organized since 24 hours ago. Numerous
moderate to isolated strong convection is seen within 90 nm of
the center in the NE quadrant, 180 nm of the center in the SE
quadrants and and 120 nm of the center in the SW quadrant. Marie
is forecast to turn toward the west-northwest tonight. Marie is
then expected to resume a northwestward heading at a faster
forward speed by Tue. Steady weakening is expected to continue
for the next several days. Marie is forecast to become a post-
tropical remnant low on Wed. Swells generated by Marie will
continue to affect portions of the coast of southwest Mexico, the
Baja California Peninsula, and Southern California for the next
few days. These swells are likely to cause life- threatening surf
and rip current conditions. Please consult products from your
local weather office.

Hurricane Center at website -

...TROPICAL WAVES...
A tropical wave has its axis along 107W from 04N to 19N. It is
moving westward near 10 kt. Isolated showers and thunderstorms
are near the wave axis, and from 19N to 21N between
the coastal waters of Jalisco and 108W.
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
The monsoon trough axis extends from near northwest Colombia,
west-southwestward through northern Panama, and to 09N84W to
10N103W to 09N111W and to 12N118W. It resumes to the southwest of
Marie at 13N126W to 10N134W and to 12N140W. Numerous moderate to
strong convection is from 01N to 07N between 130W-140W, from 03N
to 09N between 77W-83W, from 05N to 09N between 83W-90W, and
within 120 nm north of the trough between 90W-98W. Scattered
moderate to isolated strong convection is from 02N to 08N between
113W-130W.
...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
Please see the Special Features section for information on
Hurricane Marie centered well west of the southern tip of
Baja California, Mexico.
Hurricane Marie is producing moderate to locally strong cyclonic
winds and very rough seas across the far offshore waters of Baja
California, especially west of 116W and south of 27N. In the rest of
the Baja California waters, moderate or weaker winds and rough seas
are noted. In the remainder of the Mexican offshore waters, moderate
or lighter winds and slight to moderate seas are prevalent.
Isolated showers and thunderstorms are along and just offshore
Baja California Sur.
For the forecast, Hurricane Marie is forecast to weaken to a
tropical storm near 24.1N 123.2W this evening with maximum
sustained winds 60 kt gusts 75 kt, and continue to weaken as it
moves to near 24.7N 124.3W Mon morning, to near 25.3N 125.7W Mon
evening with maximum sustained winds 45 kt gusts 55 kt, to near
26.3N 127.0W Tue morning, to near 27.7N 127.9W Tue evening, to
near 29.7N 128.9W Wed morning with maximum sustained winds 35 kt
gusts 45 kt. Marie is forecast to weaken to a remnant low N of
the area by early on Thu. Elsewhere, moderate to fresh winds are
expected to briefly develop over the nearshore waters of Baja
California and in the northern Gulf of California early this week
as Marie moves farther away from the forecast waters. The next
gap wind event in the Gulf of Tehuantepec is expected to begin by
around the middle portion of the upcoming week. Looking ahead, a
trough of low several hundred 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...
A recent Ascat scatterometer pass 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
ridge by the middle of the week will result in strong gap winds
and rough seas. Meanwhile, moderate to fresh southerly winds are
expected across the waters between Ecuador and the Galapagos
Islands through at least midweek, diminishing some today through
Mon. Elsewhere, moderate or lighter winds will prevail.
...REMAINDER OF THE AREA...
Please see the Special Features section for information about
Hurricane Marie located well west of the southern tip of
Baja California, Mexico.
Outside from marine impacts attributed to Hurricane 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 Tropical Storm
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, Hurricane Marie is near 23.5N 122.5W, or about
700 nm west of the southern tip of Baja California, Mexico at 8
AM PDT, and is moving northwest at 8 kt. Maximum sustained winds
are 70 kt with gusts to 85 kt, and the minimum central pressure
is 977 mb. Marie will weaken to a tropical storm near 24.1N
123.2W this evening with maximum sustained winds 60 kt gusts 75
kt, and continue to weaken as it moves to near 24.7N 124.3W Mon
morning, to near 25.3N 125.7W Mon evening with maximum sustained
winds 45 kt gusts 55 kt, to near 26.3N 127.0W Tue morning, to
near 27.7N 127.9W Tue evening, to near 29.7N 128.9W Wed morning
with maximum sustained winds 35 kt gusts 45 kt. Marie is forecast
to weaken to a remnant low N of the area by early on Thu.
Looking ahead, cross equatorial swell will produce seas to 8 ft
in the southern waters west of 100W during much of the week. A
trough of low pressure located several hundred miles south 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.
