DISCUSSION AND OUTLOOK
----------------------
At 300 PM MDT (2100 UTC), the center of Post-Tropical Cyclone Iselle
was located near latitude 23.7 North, longitude 113.3 West. The
post-tropical cyclone is moving toward the north near 8 mph (13
km/h), and this motion is expected today, followed by a motion 
toward the north-northwest on Monday.
 
Maximum sustained winds have decreased to near 30 mph (45 km/h) 
with higher gusts.  Iselle should gradually lose strength during 
the next day or so before decaying into a surface trough on Tuesday.
 
The estimated minimum central pressure is 1007 mb (29.74 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 and
west-central coast of Mexico, as well as the west coast of Baja
California Sur.  These swells are expected to continue for the next
day or so and will likely cause life-threatening surf and rip
current conditions.  Please consult products from your local
weather office.
 
 
NEXT ADVISORY

Center on this system. For additional information on the remnant low 
please see High Seas Forecasts issued by the National Weather

Post-Tropical Cyclone Iselle Discussion Number  18

Iselle hasn't produced organized deep convection for about the past 
day, so it no longer meets the definition of a tropical cyclone.  
Thus, it is now a post-tropical remnant low, and this is the last 
advisory. The initial wind speed is set to 25 kt, which matches a 
recent ASCAT-B pass.  Models are in good agreement on the low 
gradually turning from its current northward heading to north- 
northwest tomorrow and slowly weakening due to a poor environment.  
The low is expected to degenerate into a trough of low pressure on 
Tuesday, and no changes were made from the previous forecast.
