Meteorologists warn that rainfall during the fourth week of January could trigger another mudslide in southern California, where residents of Santa Barbara county are still reeling from last week’s massive landslide. Between two and five inches fell in the county between January 8th and 9th, sending boulders and thick sediment raining down on Montecito, California. A recent wildfire in the area left mountain slopes without vegetation to slow down the runoff and played into the destruction of 115 homes and the death of at least 20 people.

Jonathan Godt of the U.S. Geological Survey told the New York Times, “It was pretty rare, in essence a worse-case scenario from that standpoint. The same rainfall that falls on a burned landscape can cause a lot more damage than it would before a fire.”

AccuWeather officials have predicted that a shift in the jet stream will bring more moisture from the Pacific Ocean into southern California’s atmosphere by January 23rd and 24th. They caution that the weather pattern presents the risk for “locally heavy rainfall, flash flooding and a significant risk of mudslides.” Their report states that areas surrounding Point Conception, California are most likely to be affected.

February and March are heavy precipitation months for Santa Barbara county, and following California’s record-setting year for wildfires, conditions are right for faster-moving and more destructive landslides.

AccuWeather meteorologist Evan Duffey said, “People need to leave the area by evacuation deadlines as they are given. Once a mudslide begins, there may only be minutes to seconds before a neighborhood is wiped out.”
