Tropical Weather Discussion
NWS National Hurricane Center Miami FL
627 UTC Sat Jun 3 2017

Tropical Weather Discussion for the eastern Pacific Ocean from
the Equator to 32N, east of 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
0830 UTC.

...TROPICAL WAVES...
A tropical wave extends from 03N91W to 15N91W and is moving W at
15 kt. The wave coincides with weak troughing aloft. Isolated 
strong convection is occurring from 06N to 14N between 89W and 
94W.

A tropical wave extends from 06N98W to 16N98W and is moving W at
10 kt. The wave coincides with the base of a mid-level trough
that stretches northward into the Western Gulf of Mexico. 
Scattered moderate convection is found within 90 nm either side 
of a line from 04N97W to 09N101W.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 
The Monsoon Trough extends from 09N78W to 13N89W, then resumes
from 10N101W to 09N121W. The ITCZ continues from 09N121W to 
beyond 07N140W. There is no significant convection currently
associated with the Monsoon Trough and ITCZ.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
The remnants of Beatriz have dissipated over SE Mexico. Showers 
and tstms that were associated with this system have ended.

Elsewhere, persistent ridging over the area will continue to 
support gentle to moderate NW winds through Monday. Fresh winds 
are likely over the waters adjacent to Los Cabos this morning. 
Seas will remain generally 4 to 7 ft through Sunday night. NW to 
N swell will propagate into the waters off Baja California Norte 
beyond 200 nm from Monday morning through Tuesday night. Surface
troughing over the Baja Peninsula will maintain light to gentle
winds over the Gulf of California through Monday night. Winds N 
of 29N will become Moderate Tuesday through Wednesday. 
Otherwise, little change in expected.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR... 
Moist southerly flow associated with the Monsoon Trough will 
continue to generate scattered showers and isolated tstms 
primarily N of 05N...mainly during the early mornings as 
monsoonal SW winds converge with overnight drainage flow off the 
coast. Some of this activity could produce locally strong gusty 
winds and rough seas. Light to gentle winds will prevail 
generally N of 10N with 4 to 6 ft seas. Moderate S to SW winds 
are expected S of 10N with corresponding seas of 5 to 7 ft as 
cross-equatorial SW swell augment combined seas.

REMAINDER OF THE AREA...
A ridge extends from 32N134W SE to the Revillagigedo Islands. The
ridge is generating moderate to fresh trade winds N of the ITCZ 
axis to 20N W of 125W. Trade-wind convergence in this area is 
producing a few thunderstorms just N of the ITCZ with seas 
exceeding 8 ft from 08N to 11N W of 136W. The ridge will continue
weakening today as a dissipating cold front crosses the eastern 
Pacific N of the area. This will allow the aforementioned seas to
subside and convection to gradually diminish. High pressure 
following in the wake of the front will provide a surge of 
moderate to fresh north winds and 5 to 7 ft seas into the region 
N of 23N between 119W and 135W Sunday and Monday, then the high 
will weaken and allow winds and seas to subside. Meanwhile, SW 
swell crossing the equator currently maintaining seas between 5 
and 7 ft as far north as 10N between 110W and 120W will gradually
subside through mid week and allow seas in this area to subside 
1 to 2 feet.
