PHOENIX - After soaking northwestern Mexico with heavy rains as it neared the Baja California Peninsula, reportedly claiming at least one victim, Tropical Storm Rosa is expected to drench the U.S. Southwest.
From Arizona to Utah, some residents filled sandbags in anticipation of heavy rainfall forecasts and potential flooding.
The center of Rosa, which was a hurricane until late Sunday, was expected to hit Baja California and Sonora by early Tuesday, bringing 3 to 6 inches (7.5 to 15 centimeters) of rain, the U.S. National Hurricane Center said.
It's then expected to move quickly northwestward as it weakens, bringing 2 to 4 inches (5 to 10 centimeters) of rain to central and southern Arizona and 1 to 2 inches (2.5 to 5 centimeters) to the rest of the desert Southwest, Central Rockies and Great Basin. Isolated areas might see even more precipitation.
