Tropical Weather Discussion
NWS National Hurricane Center Miami FL
131 UTC Fri May 12 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 0000 UTC surface analysis and satellite imagery through
0300 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 
The monsoon trough extends from 08N83W to 10N90W then from 
10N98W to 08N110W to 07N116W. ITCZ extends from 07N116W to 
06N130W to 04N140W. Scattered moderate convection is from 02N to 
11N E of 107W...and from 03N to 08N W of 130W.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
The remnant low of Adrian will drift WNW S of southern Mexico 
through Saturday night. Intermittent bursts of widely scattered
moderate convection are possible near the low-level circulation 
center and vicinity the next couple of days.

Gentle to moderate winds are noted across the northern Gulf of 
California with slightly stronger moderate to fresh NW winds
occurring across the southern Gulf of California. Winds are
expected to become light and variable by Saturday with seas
generally ranging from 1-3 ft.

A relatively weak pressure pattern W of Northern Baja California
supports moderate to occasional fresh NW winds N of 27N. A ridge
axis extends from 25N125W to near 14N108W and supports moderate 
to occasional fresh NW winds offshore of southern Baja 
California. High pressure will gradually build SE toward the area
Friday as a weakening cold front approaches from the west. The 
pressure gradient between the ridge and low pressure across 
interior portions of the SW CONUS will support fresh to strong N
to NW winds off northern Baja California late Friday through 
Sunday. Seas will build into a range of 8 to 13 ft during that 
time...highest along 30N. NW swell to 8 ft will propagate as far 
S as 22N across the offshore waters of southern Baja California 
this weekend. Conditions are expected to improve early next week.
Elsewhere between Baja California and the remnant low of 
Adrian...mainly gentle to moderate NW winds are expected through
Tuesday night with seas ranging from 5-7 ft.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR...
Mainly gentle to moderate onshore winds will prevail during the 
daytime hours...with gentle to moderate offshore winds during 
the overnight hours during the next several days. Combined seas 
of 4-7 ft will also influence the waters through the upcoming 
weekend and early next week. The monsoon trough across the 
offshore waters will provide focus for scattered areas of 
convection through the forecast period.

REMAINDER OF THE AREA...
A dissipating stationary front extends across the NW portion of 
the discussion area from 30N131W to 27N140W. The front will 
continue weakening and dissipate on Friday. As the front 
dissipates...strong high pressure N of the region will begin to 
strengthen the pressure gradient across the waters between the 
equatorial trough and 30N...resulting in fresh to strong NE winds
N of 20N with seas building to 8 to 10 ft. These winds and seas 
will prevail during the upcoming weekend.
