Mario, the 13th named storm of the 2025 eastern Pacific hurricane season, is a "tiny" storm with tropical-storm-force winds extending outward up to 25 miles north of its center, the NHC said. The storm is expected to bring two to four inches of rain, with some areas of southern Mexico receiving up to six inches, through Sunday, Sept. 14.

Mario first gained tropical storm strength Friday before it weakened into a tropical depression just hours later.
