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.

...SPECIAL FEATURES... 

Tropical Storm Dora is centered near 19.8N 113.1W at 28/0900 UTC
moving west-northwest or 285 degrees at 9 kt. Estimated minimum 
central pressure is 1005 mb. Maximum sustained winds have 
diminished to 35 kt with gusts to 55 kt. There is no longer any 
deep convection associated with Dora. Dora is forecast to weaken 
to a remnant low today, and the remnant low will dissipate 
Thursday. See latest NHC Forecast/Advisory under AWIPS/WMO 
headers MIATCMEP4/WTPZ24 KNHC for more details.

...TROPICAL WAVES...

The axis of a tropical wave is near 92W north of 05N. Scattered
moderate convection is noted from 06N to 09N between 91W and 94W.

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

The monsoon trough extends from 10N76W to 09N95W to 13N107W to
09N122W to 10.5N126W. The ITCZ extends from 10.5N126W to 11N129W
to 07N140W. Scattered moderate convection was noted within 180 nm
south of the monsoon trough between 90W and 94W. Scattered 
moderate convection was noted within 150 nm south of the monsoon 
trough between 112W and 126W. 

...DISCUSSION...   

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Outside of the influence of Dora, gentle to moderate winds prevail
in the waters west of Baja California Norte, with light to 
gentle winds prevailing elsewhere. Seas are in the 1-3 ft range in
the Gulf of California and 3-5 ft elsewhere. Little change is 
expected during the next several days.

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

Gentle to moderate SW to W winds are expected across most of the
region, except for southerly winds between Ecuador and the 
Galapagos Islands. Long period SW swell propagating into the 
region, with seas to 7-9 ft range prevailing through Thursday 
before subsiding to 4-6 ft by this weekend.

REMAINDER OF THE AREA...

The most recent scatterometer data indicate gentle to moderate
winds prevail over the forecast waters. Seas are in the 4-6 ft
range. Cross equatorial long period SW swell will continue to 
propagate across the south waters, mainly E of 125W, with seas  
building to 8-9 ft generally south of 10N.
