Kay formed on September 4th, 2022 south of the southern Mexico coast. The next day, Kay became a hurricane with maximum sustained winds of 80 mph.

Hurricane Kay reached peak intensity on September 7th as a category 2 storm with winds of 105 mph. Kay traveled nearly parallel to the Baja California coast bringing moisture to the Southwest U.S. As Kay approached Baja California, the system slowly weakened and became a remnant low on late on September 10th.

Heavy rains hit Death Valley as a result of Kay, and caused road closures in Death Valley National Park. Kay was the closest a hurricane has come to Southern California since Hurricane Nora in 1997.
