RAINFALL:  Otis is expected to produce rainfall totals of 5 to 10

inches with maximum amounts of 15 inches through Friday across

Guerrero and the western coastal sections of Oaxaca.  This rainfall

will produce flash and urban flooding, along with mudslides in areas

of higher terrain.

storm conditions are expected to first reach the coast within the

warning areas later today or this evening, and then spread

northwestward within the warning areas through Wednesday.

significant coastal flooding near and to the east of where the

center makes landfall.  Near the coast, the surge will be

accompanied by large and destructive waves.

 

SURF: Swells generated by Otis will affect portions of the southern

coast of Mexico during the next couple of days. These swells are

likely to cause life-threatening surf and rip current conditions.
