DISCUSSION AND OUTLOOK ---------------------- At 200 AM PDT (0900 UTC), the center of Tropical Storm Kay was located near latitude 29.4 North, longitude 116.0 West. Kay is moving toward the north-northwest near 13 mph (20 km/h). A slower northwestward to west-northwestward motion is forecast to begin today and continue into Saturday. 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 by Saturday. Maximum sustained winds have decreased to near 60 mph (95 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 Saturday. Tropical-storm-force winds extend outward up to 230 miles (370 km) from the center. In the past few hours, a weather station in Isla Cedros reported a sustained wind of 51 mph (82 km/h). The most recent minimum central pressure reported by an Air Force Reserve Hurricane Hunter aircraft is 990 mb (29.24 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 today. Strong winds not directly associated with Kay's core wind field are expected across portions of southern California and extreme southwestern Arizona beginning today. For information on this wind hazard, users should see High Wind Warnings and other products from their local NWS Weather Forecast Office. STORM SURGE: Coastal flooding is possible in areas of onshore winds along the west coast of the central and northern Baja California peninsula of Mexico and along the coast of the northern Gulf of California. The flooding could be accompanied by large and damaging 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: 2 to 4 inches with isolated maxima of 6 to 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.
