Tropical Weather Discussion

Tropical Weather Discussion for the eastern Pacific Ocean from
03.4S to 30N, east of 120W including the Gulf of California, and
from the Equator to 30N, between 120W and 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
0230 UTC.

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

A trough axis extends from 08N78W to 09N95W to 07N115W. The ITCZ
extends from 07N115W to 07N125W to 04N140W. Numerous moderate to
isolated strong convection is active from 10N to 13N between 116W
and 126W. Scattered moderate convection is also active from 04N
to 08N between 130W and 140W. 

...OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Broad ridging over the eastern Pacific west of Baja California is
generally maintaining moderate to locally fresh northwest winds 
over the offshore waters of Baja California, with gentle to
moderate winds elsewhere. Combined seas are 4-6 ft off Baja
California, 3-5 ft off southern Mexico, and 1-3 ft in the Gulf of
California. 

For the forecast, the high pressure over the region will maintain 
moderate to fresh northwest winds over the Baja California waters
well into next week. A tightening pressure gradient between high
pressure northwest of the region shifting eastward, with a ridge
extending southeastward across the Baja California offshore 
waters and low pressure over the western U.S. will induce fresh 
to strong southwest to west gap winds across the northern Gulf of
California briefly overnight, with a stronger, more sustained gap
wind event Sat night into Sun. Elsewhere, mostly light to gentle
west to northwest winds are expected through early next week. 

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

Light to gentle variable winds prevail north of the equator along 
with seas of 3 to 4 ft. Moderate to fresh southeast winds along 
with seas of 5 to 7 ft in long-period south to southwest swell 
continue south of the equator. 

For the forecast, a light gradient will maintain rather tranquil
conditions over the Central American and Colombian waters well 
into next week while moderate to fresh southeast winds and 
moderate long-period south to southwest swell remain offshore
Ecuador.

...REMAINDER OF THE AREA...

The gradient related to broad high pressure north of 20N is 
generally supporting gentle to moderate trades from 05N to 15N 
west of 125W, where combined seas are 7 to 8 ft primarily in 
long-period north swell. Gentle to moderate north to northeast 
winds and moderate combined seas prevail elsewhere west of 105W.
Gentle westerly winds and 2-4 ft seas are noted east of 105W.

For the forecast, the rather weak high pressure across the 
region will generally maintain moderate to fresh trade winds from
the ITCZ to 20N and west of 120W. Combined seas will be in the 
range of 5-7 ft over the western part of the area through Sat, 
then 4-6 ft across the entire area into early next week.
