At 800 PM PDT (0300 UTC), the center of Tropical Storm Iselle was
located near latitude 21.3 North, longitude 122.5 West. Iselle is

general motion is expected for the next couple of days, with a turn
towards the west possible late on Wednesday.

higher gusts. Weakening is forecast, and Iselle could become a 
post-tropical cyclone on Thursday.
 
Tropical-storm-force winds extend outward up to 230 miles (370 km)
from the center.
 
The estimated minimum central pressure is 996 mb (29.42 inches).
 
 
HAZARDS AFFECTING LAND
----------------------

Baja California Peninsula, and will continue for a couple more days.
These swells are likely to cause life-threatening surf and rip
current conditions. Please consult products from your local weather
office.
