DISCUSSION AND OUTLOOK

At 1100 PM PDT (0600 UTC), the center of Tropical Storm Kay was 
located near latitude 29.0 North, longitude 115.5 West.  Kay is 
moving toward the north-northwest near 14 mph (22 km/h).  A slower

Friday and continue into Saturday.  A turn to the west is expected 
by late Saturday.  On the forecast track, the center of Kay will 
pass near or west of the northwest coast of the Baja California 
peninsula later today. 

Maximum sustained winds are near 65 mph (100 km/h) with higher 
gusts.  Additional weakening is forecast during the next couple of 
days, and Kay is expected to degenerate into a remnant low by late 
Saturday.

Tropical-storm-force winds extend outward up to 205 miles (335 km)
from the center.

Hurricane Hunter aircraft is is 987 mb (29.18 inches).


HAZARDS AFFECTING LAND
----------------------
Key messages for Tropical Storm Kay can be found in the Tropical
Cyclone Discussion under AWIPS header MIATCDEP2 and WMO header
WTPZ42 KNHC and on the web at hurricanes.gov/text/MIATCDEP2.shtml.

WIND: Tropical storm conditions are occurring over portions of the
Tropical Storm Warning area and are forecast to spread northward
through Friday.

Strong winds not directly associated with Kay's core wind field are 
expected across portions of southern California and extreme 
southwestern Arizona beginning on Friday. For information on this 
wind hazard, users should see High Wind Warnings and other products 
from their local NWS Weather Forecast Office.

STORM SURGE: A dangerous storm surge is likely to produce coastal
flooding in areas of onshore winds along the west coast of the
central Baja California peninsula of Mexico. The surge will be
accompanied by large and destructive waves.

RAINFALL: Kay is expected to produce the following rainfall totals
through Saturday:

Baja California Peninsula: 6 to 10 inches, isolated maxima of 15
inches

Northwest Mainland Mexico:  2 to 4 inches, isolated maxima of 6
inches

Southernmost California:  3 to 5 inches with isolated maxima of 8
inches

Southwest Arizona: 1 to 2 inches with isolated maxima of 3 inches

These rainfall amounts could lead to flash flooding, with landslides
possible across mountainous areas of Mexico.

SURF:  Swells generated by Kay will continue to affect portions of
the coast of southwestern Mexico during the next day or so. Large
swells are expected to spread northward along the Baja California
peninsula coast, into the Gulf of California, and to southern
California during the next couple of days. These swells will
likely cause life-threatening surf and rip current conditions.
Please consult products from your local weather office.
