The manhunt for former LAPD officer and Navy reservist Christopher Jordan Dorner entered its third day with no new leads, as law enforcement officers searched the San Bernadino Mountains for the most wanted man in America.

The search has been hampered by blustery weather conditions that make it difficult to canvas the region. After a brief overnight hiatus due to bad weather, the dragnet continued at 7 a.m. Saturday, as officers went door-to-door looking for clues, even as the trail continued to grow cold.

Dorner, 33, has been named the suspect in a double homicide in Irvine and two officer-involved shootings in Riverside County, in which one officer was killed. He is described as African American, 6 feet tall and weighing 270 pounds.

Authorities vowed to continue the search until definitive evidence is found that proves Dorner is not in the area.

The National Weather Service said temperatures will climb to 31 degrees Saturday with little to no wind, mostly clear skies and no snow, preserving any tracks left overnight, reported the Los Angeles Times.

Helicopters were grounded Friday evening during a snowstorm that caused overnight temperatures to dip into the teens. With clear skies Saturday, authorities resumed the search, scouring the resorts areas and neighboring forests by land and air.

Currently, helicopters, snowcats and armored personnel carriers with snow chains are aiding in the search.
