On Tuesday morning, County Public Works closed Gibraltar Road at the Santa Barbara city limit due to rock slides and snow, and also closed East Camino Cielo at Painted Cave Road due to snow.

Deputy Public Works Director Tom Fayram said crews will need to clear some South Coast debris basins after the rainfall, including several within the Thomas Fire burn areas (Cold Springs, San Ysidro and Romero creeks).
The San Antonio Creek debris basin is located below the Cave Fire burn area and will need to be cleared as well, he said.
“We have been struggling with San Antonio to keep that outlet open. I think we got it finally and that keeps that basin from filling up with sand,” he said in an email Tuesday.
“All in all, everything went well, but now we have some work to do, that should start today. Nothing too threatening in the forecast,” Fayram said.
The city of Santa Barbara's Gibraltar Reservoir could spill Tuesday, Fayram added.
This week’s series of storms boosted the county to 80-percent of its normal-to-date rainfall, but it is still measured at 66-percent of its normal water year rainfall (Sept. 1 to Aug. 31).
The monitoring station at Lake Cachuma’s Bradbury Dam recorded 16.09 inches of rain in 2020, putting it at 97 percent of normal, according to the county.
