DISCUSSION AND OUTLOOK
At 200 PM PDT (2100 UTC), the center of Tropical Storm Kay was
located near latitude 31.0 North, longitude 118.0 West. Kay is
moving toward the northwest near 12 mph (19 km/h). A turn toward the
west-northwest and a decrease in forward speed are expected later
today, and a turn to the west is expected by late Saturday. On the
forecast track, the center of Kay will move parallel to the coast of
the northwestern Baja California peninsula through today, and then
begin to move further offshore tonight and Saturday.
Reports from an Air Force Reserve Hurricane Hunter aircraft and
recent satellite wind data indicate that maximum sustained winds are
now near 40 mph (65 km/h) with higher gusts. Continued weakening
is forecast during the next couple of days, and Kay is expected to
degenerate into a remnant low sometime tonight.
Tropical-storm-force winds extend outward up to 90 miles (150 km)
mainly to the east of the center. There are continued report of
50-70 mph (80-110 km/h) wind gusts in the mountains east and
northeast of San Diego, with occasional gusts to hurricane force.
The minimum central pressure estimated from the Hurricane Hunter
data is 994 mb (29.36 inches).

WIND: Tropical storm conditions are occurring over portions of the
Tropical Storm Warning area.
Strong winds not directly associated with Kay's core wind field are
occurring across portions of southern California and extreme
southwestern Arizona. For information on this wind hazard, users
should see High Wind Warnings and other products from their local
NWS Weather Forecast Office.
RAINFALL: Kay is expected to produce the following rainfall totals:
Baja California: Additional rainfall of 2 to 4 inches with isolated
maxima of 6 inches. Event total rainfall 6 to 10 inches, isolated
maxima of 15 inches
Western Sonora: Additional rainfall of 1 to 2 inches with isolated
maxima of 4 inches. Event total rainfall 2 to 4 inches, isolated
maxima of 8 inches
Southernmost California: 2 to 4 inches with isolated maxima of 6 to
Sierra Nevada, Arizona, and Southern Nevada: 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.

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 day or two. These swells will likely
cause life-threatening surf and rip current conditions. Please
