| The mudslides and flooding closed major roads, brought down power lines and caused numerous traffic accidents across Ventura and Santa Barbara Counties, northwest of Los Angeles, officials said. | The mudslides and flooding closed major roads, brought down power lines and caused numerous traffic accidents across Ventura and Santa Barbara Counties, northwest of Los Angeles, officials said. |
| “We haven’t had this much rain in a while,” said Stuart Seto, a weather specialist with the National Weather Service in Oxnard, southeast of where the mudslides occurred. The mountains that rise from the Pacific Coast have seen as much as five inches of rain over the past two days, drenching the fire-ravaged hills. “Before the rains started they were already seeing boulder slides, trees sliding. It was already loose,” Mr. Seto said. | “We haven’t had this much rain in a while,” said Stuart Seto, a weather specialist with the National Weather Service in Oxnard, southeast of where the mudslides occurred.

| “Residents living in or immediately downstream should take immediate precautions to protect life and property,” it said in a pre-dawn statement. “Quickly move away from the burn area only if it is safe to do so, otherwise shelter in place and move to a second story or the highest location in your home to stay out of the path of fast-moving water and debris flows.” | “Residents living in or immediately downstream should take immediate precautions to protect life and property,” it said in a pre-dawn statement. “Quickly move away from the burn area only if it is safe to do so, otherwise shelter in place and move to a second story or the highest location in your home to stay out of the path of fast-moving water and debris flows.” |
| Jonathan W. Godt, who coordinates the landslide hazards program at the United States Geological Survey, said the area of the Thomas fire was likely to have debris flows for two reasons: the terrain and the nature of the fire, which burned more than 280,000 acres beginning in early December. | Jonathan W.

| The fire, in a mostly chaparral landscape, also burned exceptionally hot, Dr. Godt said. A hot fire changes the physical properties of the soil, making it less absorbent. “It becomes much more erodible,” he said. | The fire, in a mostly chaparral landscape, also burned exceptionally hot, Dr. Godt said.

| As rainwater runs off and flows downhill, it picks up soil and debris and eventually collects in a stream channel. The mix of water and debris, often with a consistency close to wet concrete, can then continue traveling at high speed down the streambed. | As rainwater runs off and flows downhill, it picks up soil and debris and eventually collects in a stream channel.
