from the Equator to 30N, between 120W and 140W. The following

...SPECIAL FEATURES...

Hurricane Erick is centered near 16.7N 98.8W at 19/1500 UTC,
moving northwest at 10 kt. Estimated minimum central pressure is
980 mb. Maximum sustained wind speed is 75 kt with gusts to 90
kt. On the forecast track, the center of Erick is forecast to 
move over southern and southwestern Mexico until it dissipates 
tonight. A dangerous, life-threatening storm surge is expected
to produce coastal flooding along portions of the coast of southern
Mexico in areas of onshore winds.  The surge will be accompanied by
large and destructive waves. Swells generated by Erick will 
continue affecting the coast of southern Mexico throughout the 
day. These swells are likely to cause life-threatening surf and 
rip current conditions. Please consult products from your local 
weather office.

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

The monsoon trough extends from 10N85W to 11N91W. It resumes SW

Please read the Special Features section for the latest
information on Hurricane Erick.

Elsewhere, high pressure is centered west of Baja California 
allowing for generally moderate or weaker winds northwest winds,
except for moderate to fresh northwest to north winds north of 
about 27N. Light to gentle winds are across the Gulf of 
California, where slight seas prevail. The exception is just 
south of the southern tip of Baja California where fresh west to
northwest winds are present.

Moderate seas prevail over the remainder of offshore waters, 
except some rough seas are impacting the far northwest waters, 
where northerly swell is building in the vicinity of the 
aforementioned fresh winds. 

For the forecast, outside of the impacts of Erick, high pressure
well northwest of the area will support pulsing moderate to 
fresh northwest to north winds across the Baja California Norte 
offshore waters through the forecast period. Along with these 
winds rough northwest to north swell will build over the Baja 
waters through Thu night. The swell will be reinforced by a new 
set of northwest to north starting Fri. 

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

Winds are moderate or weaker from offshore Colombia northward, 
with moderate seas. Moderate to fresh southerly winds are 
offshore Ecuador to the Galapagos Islands, with moderate seas in 
southerly swell.

For the forecast, moderate to fresh winds will remain offshore 
Ecuador to the Galapagos Islands through the upcoming weekend 
while expanding westward. Winds will be moderate or weaker 
offshore Colombia northward, except pulse to mostly fresh speeds 
in the Papagayo region starting Thu morning. Meanwhile, moderate 
seas off Ecuador will subside some tonight, and moderate seas 
over the offshore waters of Guatemala and El Salvador will 
subside Thu.

...REMAINDER OF THE AREA...

Please read the Special Features section for details on conditions
related to Hurricane Erick.

Broad surface ridging extends from a high pressure centered well
northwest of the discussion area to across the open waters north
of the monsoon trough and ITCZ and west of about 120W. Mostly 
moderate trades are north of about 14N west of 130W while 
moderate to fresh trades are north of 17N and between a line from
26N119W to 17N125W and 130W. Seas are moderate with these winds.
Gentle to moderate southerly winds are south of the monsoon 
trough along with moderate seas.

For the forecast, high pressure north of the area will shift
slightly southward through Fri. Moderate to fresh northeast 
winds over the northwest part of the area will expand in coverage
going into the weekend. Seas will build over the northeast part 
of the area through the weekend as a new and larger set of 
north swell propagates through those waters. The swell will 
become more from the north to northeast in direction as it 
spreads to the west of 127W, crossing 140W during the weekend.
