DISCUSSION AND OUTLOOK
At 1200 AM MDT (0600 UTC), the center of Hurricane Kay was located
near latitude 19.7 North, longitude 111.8 West. Kay is moving toward
the northwest near 13 mph (20 km/h). A turn toward the
north-northwest is expected today, and this motion should continue
into Friday. On the forecast track, the center of Kay is expected
to pass to the west of the southern Baja California peninsula
today, and be near the west-central coast of the Baja California
peninsula Thursday and Friday.
Maximum sustained winds are near 90 mph (150 km/h) with higher
gusts. Strengthening is forecast during the next 24 hours, and Kay
could become a major hurricane during that time. Weakening is
forecast to begin by Thursday, but Kay is forecast to remain a
strong hurricane when it passes near the Baja California peninsula.
Hurricane-force winds extend outward up to 30 miles (45 km) from
the center and tropical-storm-force winds extend outward up to 205
miles (335 km).
The estimated minimum central pressure is 975 mb (28.80 inches).

WIND: Hurricane conditions are possible in the Hurricane Watch area
beginning Thursday. Tropical storm conditions are expected in the
Tropical Storm Warning area beginning this morning and are forecast
to spread northward tonight and Thursday. Tropical storm conditions
are possible in the Tropical Storm Watch area on Thursday.
STORM SURGE: A storm surge could produce coastal flooding near
where the center passes the coast in areas of onshore winds, or
east of the center if Kay makes landfall. The surge will be
accompanied by large and destructive waves.
RAINFALL: Kay is expected to produce rainfall totals of...
Baja California Peninsula: 6 to 10 inches, isolated maxima of 15
Northwest Mainland Mexico: 2 to 4 inches, isolated maxima of 6
Southernmost California: 1 to 3 inches with maxima of 5 inches
through Saturday morning
These rainfall amounts could lead to flash flooding across the above
areas, including landslides across mountainous areas of Mexico.
SURF: Swells generated by Kay will continue to affect portions of
the coast of southwestern Mexico during the next couple of days.
Large swells are expected to spread northward along the Baja
California peninsula coast and into the Gulf of California during
the next few days. These swells will likely cause life-threatening
surf and rip current conditions. Please consult products from your
local weather office.
