California mudslides: Death toll rises to 20, 4 still missing

(CNN) — At least 20 people have died as a result of the mudslides that devastated Montecito, California, according to the California Department of Fire and Forestry Protection. Four people are still missing.
The mudslides came in the early morning hours of Tuesday, destroying an estimated 65 homes and damaging hundreds of others, the Cal Fire release said.
Rescue crews continue to sift through mud and wreckage looking for missing victims, said Cal Fire, adding, "The large amounts of mud and debris are making access and progress challenging."
Santa Barbara County Sheriff Bill Brown announced Saturday that search and rescue crews had found the body of 25-year-old Morgan Corey, whose 12-year-old sister, Sawyer, was found dead earlier in the week.
Those killed ranged in age from 3 to 89, and all lived in Montecito in Santa Barbara County, northwest of Los Angeles, authorities said.
Officials have stressed they expect the number of missing persons "to fluctuate significantly."
Rescuers have been searching frantically for the missing since rivers of mud and boulders plowed through neighborhoods in and near Montecito, an affluent seaside community east of Santa Barbara, demolishing homes and leaving roads impassable.
"In disaster circumstances, there have been many miraculous stories of people lasting many days. We certainly are searching for a miracle right now," Brown said Thursday.
"But realistically we suspect that we are going to continue to have discovery of people who were killed in this incident."
Evacuation zone increased
The immediate areas where people were killed are under mandatory evacuation, and officials increased the size of the evacuation zone Thursday as authorities continue their search and rescue efforts.
"We know that this a terribly inconvenient development, but it is also incredibly necessary," Brown said. "This entire area is a very active rescue and recovery and repair zone right now."
The zone, which includes areas formerly under voluntary evacuation advisories, will be in effect for one week but residents should plan for two, Brown said.
Rescue workers are using helicopters and all-terrain vehicles in a search hampered by blocked roads and downed trees and power lines.
Billy Grokenberger lives in a part of Montecito that was under a voluntary evacuation order. He and his parents put their belongings in three cars in case they decided to leave before the storm. They didn't.
"We had thought about leaving, but we had just had the fires," he said, referring to the recent wildfires that stripped the area of needed vegetation. "... We didn't take it serious(ly) enough."
On the morning of the storm, Grokenberger watched as 2 to 3 feet of water streamed down the street.
"(In) four minutes the water was through our wall and in our house, almost to the second story," he said.
"The house is destroyed, but you know, there's just so many others who are less fortunate. But we just feel lucky that we were able to get out and (are) alive."
Risk of mudslides for years
The storm hit hard between 3 and 6 a.m. Tuesday. The rain poured down on hillsides charred by recent wildfires, which burned vegetation that otherwise could make the terrain more resistant to mudslides.
The Thomas Fire -- the largest wildfire in California's recorded history -- burned more than 281,000 acres in Santa Barbara and Ventura counties from early December into this month. It wasn't fully contained until this week.
Geologists and forecasters warned that intense rain could trigger deadly mudslides from the scorched areas.
And because of the fire, communities below the scarred terrain could remain at risk of mudslides for years, said Randall Jibson, a research geologist with the US Geological Survey.
Montecito may be at slightly less risk now, because this week's flooding already brought down vulnerable material.
"(But) no storm brings down everything that is susceptible. There's almost always more" that could come down, Jibson said.
What can be done? One long-term option would be to build more basins to slow down storm runoff and collect debris.
Short term, making the public ready to evacuate during heavy rains is key, he said.
Montecito and Carpinteria are especially vulnerable to mudslides because their steep terrain in some places goes from thousands of feet above sea level to the ocean in just a few miles, said Tom Fayram, a deputy public works director with Santa Barbara County.
