tropical wave which helped spawn TD 14 in the western Caribbean. 
Scattered moderate convection is noted from 08N to 13N E of 90W.
Heavy rainfall could lead to flash flooding over portions of 
Central America through the weekend.

A tropical wave axis is analyzed near 106W from 04N to 18N, 
moving W at 10-15 kt. Scattered moderate convection is noted 
from 07N to 13N between 105W and 110W.

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

The monsoon trough extends from 12N87W to 13N99W to 17N111W to 
11N135W to 11N140W. Besides the convection described above, 
scattered moderate and isolated strong convection is noted within

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Please see the Special Features section above for details about 
Tropical Storm Genevieve. Elsewhere, expect fresh to strong S to
SE winds in the northern Gulf of California today with seas

Expect freshening winds and building seas off the coast of 
Central America through the upcoming weekend and into early next 
week. Seas will build to 8-10 ft offshore of Central America by 
this weekend in association with the strongest winds, then 
continue building to 9-11 ft early next week as monsoonal flow 
continues strengthening. 

REMAINDER OF THE AREA...

A modest pressure gradient between high pressure north of the
area and the monsoon trough is supporting gentle to moderate 
trades N of 20N and W of 125W. Moderate to locally fresh SW 
winds persist south of the monsoon trough. Seas are in the 7-9 
ft range within these fresh trades. This monsoonal flow is 
expected to strengthen E of 115W this weekend into early next 
week, with seas building to 8-12 ft.
