At 5 a.m. HST, the center of Hurricane Kiko was located near latitude 17.3°N, longitude 123.7°W approximately 975 miles WSW of Baja California. Kiko is moving toward the west at near 5 mph, and this motion is expected to continue through tonight. A west-southwestward motion is forecast for Tuesday and Tuesday night, followed by a turn back to the west on Wednesday.

Maximum sustained winds have decreased to near 105 mph with higher gusts. Gradual weakening is expected during the next couple of days.

Kiko is a small tropical cyclone. Hurricane-force winds extend outward up to 15 miles from the center and tropical-storm-force winds extend outward up to 60 miles.

The estimated minimum central pressure is 28.68 inches.
