NWS National Hurricane Center Miami FL
1005 UTC Thu Nov 28 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.

.TROPICAL WAVES...

A tropical wave axis is along 90W north of 08N moving west at 10 
to 15 kt. Scattered moderate isolated strong convection is noted 
from 06N to 08N between 90W and 95W. This wave is expected to 
track slowly westward over the next two days.

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

The monsoon trough extends from 08N78W to 08N97W to 11N109W to 
09N118W to 10N129W. The ITCZ continues from 10N129W to beyond 
10N140W. Scattered moderate isolated strong convection is noted 
from 07N to 10N between 111W and 116W.

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

1005 mb low pressure near 26N112W will move northeast into NW 
Mexico later today. A cold front across northern Baja California 
from Yuma Arizona to 28N120W will extend from the central Gulf 
of California to 23N119W by Fri morning. A deepening trough over 
the southwest U.S. will induce near gale force southerly winds 
ahead of the front in the northern Gulf of California tonight.
Large NW swell, with seas from 8 to 11 ft, prevail across the 
offshore waters of Baja California. Large long period NW swell 
associated with the cold front will sweep southeastward west of 
the Baja peninsula through Fri morning, peaking near 14 ft off 
Baja California Norte tonight, then gradually subside through 
Saturday. Looking ahead, another set of NW swell will move into 
the waters off Baja California Norte early Mon. In the Gulf of 
Tehuantepec, moderate to fresh northerly gap winds are expected 
to pulse to around 20-25 kt each night through early Sat, then 
again Sun night, with gale force winds possible Mon night.

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

Fresh to occasionally strong NE to E winds will pulse across and 
downstream from the Gulf of Papagayo at night through Monday. 
Gentle to moderate S to SW monsoon flow will persist across the 
offshore waters of Costa Rica, Panama, Colombia, and Ecuador the 
next several days, along with moderate long period SW swell, 
supporting 4 to 7 ft seas.

REMAINDER OF THE AREA...

A cold front extends across the NE part of the forecast area 
from just south of Ensenada Mexico to 28N120W to 26N127W. The 
front will usher in a set of large long period NW swell, with 
maximum seas expected to near 15-16 ft N of 27N between 120W and 
132W this morning. Another cold front will move into the NW 
waters Fri and Sat, with reinforcing large long period NW swell 
expected to peak near 19-20 ft over the far NW waters by early 
Sun. Seas of 8 ft or greater are likely over much of the 
forecast waters N of 10N and W of 115W through the weekend.
