DISCUSSION AND OUTLOOK
----------------------
At 200 PM PDT (2100 UTC), the center of Tropical Storm Iselle was
located near latitude 18.8 North, longitude 115.2 West. Iselle is
moving toward the north-northeast near 7 mph (11 km/h) and this
general motion is expected to continue through tonight.  A
northward turn is expected by Saturday morning followed by a
north-northwestward motion on Sunday morning.  Afterward,
Post-Tropical/Remnant Low Iselle is forecast to turn northwestward 
in the low-level flow.

Maximum sustained winds have decreased to near 50 mph (85 km/h) 
with higher gusts.  Further weakening is forecast and Iselle should 
become a tropical depression Saturday night, degenerate to a 
remnant low on Sunday and dissipate early next week.

An observing site at Clarion Island, MX recently reported a 
sustained wind of 40 mph (65 km/hr) and a gust of 48 mph (80 km/hr).
 
Tropical-storm-force winds extend outward up to 70 miles (110 km)
from the center.
 
The estimated minimum central pressure is 999 mb (29.50 inches).
 
 
HAZARDS AFFECTING LAND
----------------------
SURF:  Swells generated by Iselle and a large area of southwesterly
winds to its south are affecting portions of the southwestern coast
of Mexico.  These swells are expected to spread northward along
the coast of west-central Mexico and the southern Baja California
peninsula through Sunday, and will likely cause life-threatening
surf and rip current conditions.  Please consult products from your
local weather office.
