WIND: Tropical storm conditions are occurring over portions of the
Tropical Storm Warning area and are forecast to spread northward
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
Baja California Peninsula: 6 to 10 inches, isolated maxima of 15
Northwest Mainland Mexico: 2 to 4 inches, isolated maxima of 6
Southernmost California: 3 to 5 inches with isolated maxima of 8
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.
