Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1957 UTC Fri Jun 2 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 1800 UTC surface analysis and satellite imagery through
2100 UTC.

...TROPICAL WAVES...
Tropical wave extends from 03N87W to 13N87W moving W at 10 to 15
kt. The wave coincides with subtle troughing aloft between 86W 
and 91W. Isolated moderate convection is from 06N to 10N between
81W and 87W.

Tropical wave extends from 03N95W to 11N94W moving W at 5 to 10 
kt. The wave coincides with subtle mid-level troughing between 
95W and 99W. Isolated moderate convection is from 05N to 11N 
between 90W and 96W.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 
The Monsoon Trough extends from 14N97W to 09N104W to 09N121W. 
The ITCZ extends from 09N121W to 08N140W. Scattered moderate and
isolated strong convection is from 09N to 14N between 97W and 
102W...and within 90 nm either side of the ITCZ axis W of 136W.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
The remnant low of Beatriz continues to be located across
southern Mexico with scattered showers and isolated tstms
occurring across the generally between 92W and 98W...including
the coastal waters N of 13N between 93W and 100W. Please see 
local forecasts for more information on the lingering potential 
for heavy rainfall and landslides.

Elsewhere...persistent ridging into the area will continue to 
support gentle to moderate NW winds through Monday. A brief pulse
of fresh winds is likely off Los Cabos tonight. Seas will remain
generally 4 to 7 ft into Sunday. Northerly swell will propagate 
into the waters off Baja California Norte beyond 200 nm from late
Sunday to Tuesday. 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 early mornings as the 
SW flow converges 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 08N with 4 to 6 ft seas. Moderate S to SW winds are expected 
S of 08N with corresponding seas of 5 to 7 ft due to a component
of cross-equatorial southerly swell.

REMAINDER OF THE AREA...
A ridge extends from 30N140W southeastward to the Revillagigedo 
Islands supporting moderate to fresh trade winds generally N of
the ITCZ axis to 17N W of 130W. Trade wind convergence in this 
area is supporting scattered moderate to isolated strong 
convection along the ITCZ, and seas to 9 ft. The ridge will
continue weakening through late Saturday as a cold front moves 
across the eastern Pacific N of the area...allowing the 
aforementioned seas to subside and convection to gradually
diminish. High pressure building in the wake of the front will 
support a push of moderate to fresh northerly flow and 5 to 7 ft 
seas into the region N of 23N between 119W and 135W Sunday into 
Monday...before decaying Tuesday. Meanwhile southerly...cross- 
equatorial swell of 5 to 7 ft reaching as far north as 10N 
between 110W and 120W will gradually subside through early next 
week.
