ALBUQUERQUE, New Mexico (AP) -- A powerful storm system that has caused hundreds of accidents across the Western U.S. has marched eastward with predictions of widespread snow, freezing temperatures and gusty winds.
 
   The fierce weather has caused at least eight deaths and prompted advisories Saturday afternoon in New Mexico and Texas.
 
   As thick, gray clouds covered the Southwest, forecasters said the storm would sweep across the South and toward the Atlantic coast next week, causing problems for holiday travelers.
 
   In New Mexico, authorities and residents braced for the second hit of a one-two punch that had already blanketed parts of the state with snow and freezing rain and caused a rollover accident that killed a 4-year-old girl in the eastern part of the state.
 
   Three other storm-related deaths were reported Saturday in a crash in the Texas Panhandle involving nearly a dozen vehicles.
 
   In California, where the storm system hit first, prompting flooding and water rescues in recent days, three deaths have been linked to the storms since Thursday. Authorities found one body near downed power lines, one man crashed his vehicle into a tree, and a woman was killed when a tree fell on a parked car.
 
   In Arizona, firefighters recovered the body of a man who was swept away by high waters Friday in the Santa Cruz River in the southern part of the state.
 
   The storm already has affected much of the Western U.S., causing hundreds of rollover accidents and prompting officials to cancel events and close roads.
 
   In Nevada, snow in high elevations in the rural, eastern part of the state stranded dozens of cars. No fatalities were reported and authorities got the road open again by Saturday.
 
   In Arizona, rain came down Saturday as more than 8,000 cyclists competed in the annual El Tour de Tucson. Also, high school football games, soccer tournaments and parades were cancelled across the state.
 
   Forecasters said parts of both California and Arizona could expect severe weather with winter storm warnings through Saturday. Weather officials said the mountains and the Antelope Valley foothills northeast of Los Angeles were under the most risk. However, they said there was only a small chance of rainstorms like those that prompted flooding in California on Thursday.
 
   In Texas, freezing rain and cold temperatures have already hampered travel. Several traffic accidents were reported Saturday, including the fatal crash late Friday that also left several injured in Vega, about 30 miles (50 kilometers) west of Amarillo, and one that injured three members of singer Willie Nelson's band when their bus struck a pillar near Sulphur Springs, north of Dallas.
