NWS National Hurricane Center Miami FL
2205 UTC Fri Mar 10 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.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...  

The ITCZ has shifted south of the equator, and minimal random 
convection is occurring in the discussion area at this time.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A surface ridge west of Baja California will shift slowly west 
through Saturday. Gentle to moderate west to northwest flow west 
of 105W will diminish to a light to gentle breeze by Sunday, 
except for a narrow swath of moderate NW winds near 19.5N105.5W. 

Gulf of Tehuantepec: Strong northerly winds will develop again 
tonight across and downstream of the Gulf of Tehuantepec, and 
continue through sunrise on Saturday morning, with the maximum 
seas building to 10 ft near 14.5N95W. Another gap event will 
develop late Sunday night and again Monday night, with guidance 
suggesting a brief period of gale winds possible Tuesday evening.

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR...

Gulf of Papagayo: A swath of strong NE winds are expected across 
the waters from 10N to 11N between 86W-89W tonight. The strong 
winds will create NE swell that will mix with cross equatorial 
SW swell, creating an area of seas to 8 ft near 08N98W tonight. 
Light to gentle winds and combined seas of 4-6 ft are occurring 
elsewhere outside of the swells originating near the gap events. 

REMAINDER OF THE AREA...

A nearly stationary surface high centered near 33N129W supports 
a broad ridge over the forecast area with fresh ne trades across 
the tropics from 07N to 15N west of 114W, which will continue 
for a few more days. Mixed swell will produce combined 7-9 ft 
seas across the area through early Monday.
