NWS National Hurricane Center Miami FL
0405 UTC Fri Apr 13 2018

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... 

A surface trough extends from 08N83W to 07N88W to 07N100W. The 
ITCZ continues from 07N100W to 06N116W to 07N130W to 06N140W. 
Scattered moderate isolated strong convection is from 06N to 09N 
between 86W and 94W, and from 04N to 12N between 110W and 120W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Strong NW winds and large NW swell will prevail west of Baja 
California Norte overnight. Strong NW winds are forecast across 
the length of the Gulf of California from Fri through early Sun. 
Strong N to NE gale force winds are forecast to begin over the 
Gulf of Tehuantepec starting Sun, continuing into Tue morning.

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

Light to gentle winds are expected through the forecast period. 
Seas in the 3 to 4 ft range will continue over most of the area. 
Fresh gap winds are likely in the Gulf of Papagayo tonight, and 
possible again starting Tue.

REMAINDER OF THE AREA... 

The pressure gradient between lower pressure in the vicinity of 
the ITCZ and high pressure centered N of the area near 35N133W 
is producing moderate to fresh trade winds north of the ITCZ and 
west of 110W. Ridging will build east-southeastward through Sat, 
with a tighter gradient increasing the trade winds across the 
tropical Pacific. Large NW swell propagating SE across forecast 
waters, with max seas to 13-14 ft, will slowly diminish through 
Mon night.
