meteorological analysis.

Based on 0600 UTC surface analysis and satellite imagery through

...SPECIAL FEATURES... 
Hurricane Eugene is centered near 18.1N 116.5W at 10/0900 UTC or
about 470 nm SW of the southern tip of Baja California moving NW
at 10 kt. Estimated minimum central pressure is 976 mb. Maximum 
sustained wind speed is 85 kt with gusts to 105 kt. Scattered to
numerous moderate convection is within 150 nm of the center. 
Eugene will weaken further on Monday and Monday night and move 
NW across cooler waters. See latest NHC Forecast/ Advisory under
AWIPS/WMO headers MIATCMEP5/WTPZ25 KNHC for more details. 

...TROPICAL WAVES...
A tropical wave extends from 10N109W to 18N108W moving W at 15 
kt. No significant deep convection is occurring with the wave at 
this time.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 
The Monsoon Trough axis extends from 10N86W to 13N95W to Low 
Pres 1011 mb 12N103W then resumes from 14N120W to 10N129W to 
10N136W. The ITCZ extends from 10N136W to 11N140W. Scattered

between 77W and 92W.

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...
The area of tropical storm force winds is near Clarion currently 
as Eugene begins to gradually move NW of that island during the 
day on Monday. Fresh to strong winds and seas 10 to 14 ft along 
with occasional squalls are expected elsewhere across the 
Revillagigedo Islands through Monday.

Elsewhere, moderate to fresh southerly flow will affect the 
waters beyond 210 nm off the coast of Baja California as Eugene 
moves NW roughly parallel to the peninsula through Wednesday. 
Large swell generated by the tropical cyclone will increase seas
to 8-12 ft in this area.

The pressure gradient between ridging W of Baja California Norte
and troughing across the Baja California peninsula is supporting 
gentle to moderate southerly flow which is expected to persist
through much of the week ahead. Farther south, brief pulses of
moderate to occasional fresh winds are possible across the Gulf 
of Tehuantepec each late night into the early morning hours
through Friday. Seas briefly building to 6-8 ft each morning.
    
OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, AND 
WITHIN 750 NM OF ECUADOR...
Moderate to fresh nocturnal winds are expected across the Gulf 
of Papagayo the next couple of days. Gentle to moderate southerly
winds are expected south of the Monsoon Trough axis. Long period
cross-equatorial southerly swell and seas to 6-8 ft west of 
Colombia and Ecuador will continue through Tuesday night.
Thereafter...5-7 ft seas in moderate S-SW winds are expected.

REMAINDER OF THE AREA...
See the Special Features section for more information on Eugene.
Outside of this area, moderate to fresh trade winds will prevail
N of the Monsoon Trough, while gentle to moderate southerly 
winds will be S of the trough axis. Seas will be generally 5 to 
7 ft, except to 7-8 ft near the Equator. Little change is 
expected in the waters S of 20N through mid week.
