RAINFALL: Bands of heavy rainfall will continue to impact Baja California Sur and Sonora Mexico through Friday. Additional rainfall totals of 4 to 8 inches, with maximum storm total amounts of 12 inches, are possible across portions of Baja California Sur, far southeast Baja California, southwestern Sonora, and northern Sinaloa through Friday night. This will bring the risk of life-threatening flash floods and mudslides, especially in areas of higher terrain.

Elsewhere across Mexico, 2 to 4 inches of rain, with isolated totals up to 6 inches, are expected across the remainder of Sonora. These amounts will lead to isolated to scattered instances of flash flooding.

Across the southwestern United States, 1 to 2 inches of rain, with isolated totals up to 4 inches, are expected across portions of Arizona and New Mexico through Saturday, bringing the potential for isolated to scattered flash flooding.
