Tropical Weather Discussion
NWS National Hurricane Center Miami FL
1005 UTC Mon Mar 27 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 0600 UTC surface analysis and satellite imagery through 
0900 UTC.

...INTERTROPICAL CONVERGENCE ZONE... 

The ITCZ remains south of the equator,  west of 127W. No large 
areas of significant convection evident in the discussion area.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

A broad ridge extends from the central Pacific to near the 
Revillagigedo Islands. The pressure gradient between the ridge 
and lower pressures over Mexico is supporting moderate to fresh 
NW winds west of the Baja California peninsula. Strong high 
pressure will shift eastward today and increase winds across the 
offshore waters of Baja California by early Tuesday. Marine 
model guidance shows seas building to 8-10 ft from the stronger 
winds. Large long period NW swell will propagate into the waters 
off Baja California Norte today, peaking near 13 ft early 
Tuesday morning. 

As the high pressure builds farther east, expect increasing 
winds to 20-25 kt in the northern Gulf of California by early 
Tuesday morning, spreading south across the central waters later 
in the day. Elsewhere, winds will generally be light to gentle 
with seas in the 4-6 ft range through the middle of the week. 

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

Fresh NE winds are expected in the Gulf of Papagayo this 
morning. Gentle to moderate northerly winds are expected across 
the Gulf of Panama at night. Light to gentle winds and seas of 3-
5 ft are expected elsewhere the next several days.

REMAINDER OF THE AREA...

High pressure prevails over the northern waters. The pressure
gradient between this area of high pressure and the equatorial 
trough is supporting fresh to strong trades over the trade wind 
belt. Seas over this area are in the 8-10 ft range in a mix of 
long period NW swell and NE wind waves. This area of trades will 
persist through Monday, but the aerial extent of the trades will 
increase by tonight as high pressure north the area strengthens.
