Tropical Storm Rosa neared Mexico’s Baja California on Monday, spreading heavy rains that were projected to extend into a drenching of the Southwest U.S. Forecasters said the rain may cause “life-threatening flash flooding.”
The U.S. National Hurricane Center said the center of Rosa, which was a hurricane until late Sunday, should hit Baja California and Sonora state late Monday, bringing 3 to 6 inches of rain. It’s then expected to move quickly northwestward as it weakens, bringing 2 to 4 inches of rain to central and southern Arizona and 1 to 2 inches to the rest of the desert Southwest, Central Rockies and Great Basin.
Some isolated areas might experience more. “These rainfall amounts may produce life-threatening flash flooding,” the hurricane center said in an advisory early Monday. “Dangerous debris flows and landslides are also possible in mountainous terrain.”
