Tropical Weather Discussion

1223 UTC Sun Mar 26 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 1200 UTC surface analysis and satellite imagery through
1500 UTC.

...INTERTROPICAL CONVERGENCE ZONE... 

The ITCZ extends from 04N97W to 03N101W to 07N112W to 03N130W.
Scattered moderate convection was noted within 90 nm north of 
the ITCZ between 115W and 120W. Scattered moderate isolated
strong convection was noted within 60 nm of the ITCZ between 127W
and 130W. 

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

High pressure centered near 30N130W extends a ridge southeast to
near the Revillagigedo Islands. The pressure gradient between The
ridge and a trough of low pressure over the Gulf of California is
supporting moderate to fresh winds west of the Baja California
peninsula with seas in the 6-8 ft range. Light to gentle winds
with seas 2 ft or less prevails over the Gulf of California.
Light winds with seas in the 4-6 ft range prevails elsewhere.
The area of high pressure will further building early next week,
which will tighten the pressure gradient and strengthen winds 
off the coast of Baja California Norte. Northwesterly swell will 
propagate into the waters off Baja California Norte Monday, and 
peak near 13 ft early Tuesday morning. 

Winds will strengthen over the northern Gulf of California early
Tuesday as the pressure gradient tightens before diminishing
Wednesday as the area of high pressure weakens slightly and
loosens the pressure gradient. Elsewhere, winds will generally 
be light to gentle with seas in the 4-6 ft range through the 
middle of next week. 

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

Fresh NE winds are expected over the Gulf of Papagayo during the 
late night hours tonight into the early morning hours Monday 
morning. 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 tradewind
belt. Seas over this area are in the 8-10 ft range in a mix of
northwesterly and northeasterly swell. High pressure will prevail
over the northern waters the next several days. This will
maintain the fresh to strong trades.
