The U.S. Forest Service said Monday morning that the Rey Fire had grown to 23,546 acres with 20 percent containment.
"Today, the fire is expected to continue to display extreme fire behavior due to dry vegetation and easily combustible fuels due to ongoing drought conditions," the incident update stated. "People can expect to see smoke and ashfall in Santa Barbara, Montecito, and Carpenteria for the next couple of days as the fire grows east/northeast towards the Dick Smith Wilderness."
As of Monday, the west side of the fire was holding. The south side was holding north of the Santa Ynez River and crews were expected to strengthen lines.
While not anticipated to be used, contingency lines were being constructed, including on the existing East Camino Cielo fuel break. As a result, East Camino Cielo Road will be closed.
The north side of the fire required significant line construction. This area has burned into the old Zaca burn area from 9 years ago.
