DISCUSSION AND OUTLOOK
----------------------
At 800 AM PDT (1500 UTC), the center of Tropical Storm Iselle was
located near latitude 18.3 North, longitude 115.3 West. Iselle is
moving toward the northeast near 5 mph (7 km/h) and this
general motion is expected to continue through tonight.  A
northward turn is expected by Saturday morning followed by a
northwestward motion on Sunday evening.  Afterward,
Post-Tropical/Remnant Low Iselle is forecast to turn
west-northwestward in the low-level easterly flow.

Maximum sustained winds are near 60 mph (95 km/h) with higher gusts.
Some fluctuations in strength are possible today, but a gradual
weakening trend should commence later tonight.  An observing site
at Clarion Island, MX recently reported a sustained wind of 39 mph
(65 km/hr) and a gust of 47 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 997 mb (29.44 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.
