Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Tue Feb 26 2019

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 
0900 UTC.

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

A trough extends from 07N82W to 01N100W. The intertropical 
convergence zone axis continues from 01N100W to 01N114W to 
07N130W to 07N140W. Scattered moderate rain showers are within 
75 nm either side of the boundary between 115W and 134W.

...DISCUSSION...

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...  

High pressure north of the region will support mainly gentle to 
moderate NW winds off Mexico through the weekend. NW swell will 
build offshore Baja California Norte by the weekend. 

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

Persistent strong trade winds over the SW Caribbean will support 
strong to gap winds through the Gulf of Papagayo, and fresh to 
strong winds elsewhere off the coast of Nicaragua to the Gulf of 
Fonseca. The combination of gap winds off Nicaragua and Costa 
Rica will produce an area of seas to 11 ft downstream, which 
will subside to below 8 ft by late week. Moderate to fresh 
northerly gap winds will be active through the Gulf of Panama, 
mainly near the Azuero peninsula, the next couple of nights.

REMAINDER OF THE AREA... 

1021 mb high pressure is centered near 23N120W. Fresh trades S 
of the high between 10N and 15N supports seas of 8 to 9 ft. W of 
the high, a weak cold front has disrupted the subtropical ridge, 
resulting in moderate trade winds. Altimeter passes from farther 
west confirm large NW swell will follow the front. Swell greater 
than 8 ft will cover the waters N of 10N west of 125W by Thu. 

By late Thu and Fri, model guidance indicates a deepening low 
pressure area W of the area by the end of the week. Strong 
southerly winds and seas building to 12 ft are likely N of 20N 
west of 130W by early Fri as the low pressure and its associated 
frontal boundary move to the north of the area. Looking ahead, 
winds and seas gradually diminish Sat and Sun as the low 
pressure moves farther north of the region.
