Heavy rains from Tropical Storm Javier to hit Southwest

Heavy rain associated with Tropical Storm Javier in Mexico is expected to hit much of the American Southwest and bring the possibility of more flash floods

Forecasters say the new storms may remain through Thursday and could affect Arizona, New Mexico and the southern parts of Utah and Colorado.

On Tuesday, the storm front hit southern Arizona, causing flooding and warnings from officials to stay off roads. Tucson's street car, for example, shut down because of flooding around the downtown area. Heavy rains have also caused traffic backups on Interstate 10 in Tucson.

Phoenix also could see possible flash flooding just days after the state saw damaging severe weather, the National Weather Service said.

Navajo Nation President Russell Begaye recently signed an emergency declaration in response to last week's flash flooding that damaged homes, washed out roadways and killed livestock last week in Shiprock and Chinle. The Navajo Nation encompasses parts of Arizona, New Mexico and Utah.

Mexican authorities evacuated people from low-lying areas around the resort city of Cabo San Lucas as Tropical Storm Javier blew past the tip of Mexico's Baja California Peninsula before weakening to a tropical depression Tuesday.
