DISCUSSION AND OUTLOOK

At 600 PM MDT (0000 UTC), the center of Tropical Storm Olaf was 
located near latitude 24.7 North, longitude 113.0 West.  Olaf is 
moving toward the west-northwest near 10 mph (17 km/h).  A turn 
toward the west is expected tonight and Saturday, followed by a 
southwestward motion beginning on Saturday night and continuing into 
early next week.  On the forecast track, the center of Olaf will 
continue moving away from the southwestern coast of Baja California 
Sur tonight.
 
Maximum sustained winds have decreased to near 40 mph (65 km/h)
with higher gusts.  Additional weakening is expected during the next
couple of days, and Olaf is forecast to degenerate to a
post-tropical remnant low tomorrow.
 
Tropical-storm-force winds extend outward up to 45 miles (75 km)
from the center.
 
The estimated minimum central pressure is 1003 mb (29.61 inches).

Key messages for Olaf can be found in the Tropical Cyclone
Discussion under AWIPS header MIATCDEP5 and WMO header WTPZ45 KNHC
and on the web at hurricanes.gov/graphics_ep5.shtml?key_messages
 
WIND:  Tropical storm conditions are occurring within portions of
the tropical storm warning area, but are expected to subside during
the next several hours.
 
RAINFALL:  Olaf is expected to produce an additional 2 to 4 inches
of rain with isolated maximum amounts of 6 inches across portions of
southern Baja California Sur through tonight. This rainfall may
trigger life-threatening flash flooding and mudslides.
 
STORM SURGE:  Storm surge is expected to produce coastal flooding in
regions of onshore winds within the warning area.  Near the coast,
the surge will be accompanied by large waves.
 
SURF:  Swells generated by Olaf will affect portions of the coasts
of Nayarit and Sinaloa through this evening, and portions of the
west coast of Baja California Sur through Saturday.  These swells
are likely to cause life-threatening surf and rip current
conditions.  Please consult products from your local weather office.
