California storms to bring rain threat of floods
GLENDORA, Calif. (AP) -- People in fire-scarred neighborhoods sandbagged their homes in anticipation of the first significant California storms in months to barrel down from the north, promising much-needed rain to the drought-stricken state but also the threat of mudslides and flooding.
The first storm was expected to hit Northern California Wednesday morning and move down the coast, dumping a half-inch to an inch in southern areas late in the day, forecasters said.
A potentially stronger storm moving in late Thursday could bring thunder and dump up to 2 inches of rain in central and southern valleys, 2 to 4 inches in the foothills and up to 6 inches in some mountain spots.
After 2013 ended as the state's driest year on record, all that predicted rain and snow should be nothing but good news. But there also was the risky side of the downpours.
If the rainfall rate is intense, it could bring flash flooding, "and our ground is so dry ... that we'll probably get more runoff than we're absorbing," said Bonnie Bartling, a National Weather Service weather specialist in Oxnard.
Residents of cities such as Glendora and Azusa at the foot of the steep San Gabriel Mountains east of Los Angeles faced the prospect of debris flows and mudslides from nearly 2,000 acres of barren slopes burned by a wildfire in January.
Crews placed concrete barriers along several streets in the two cities.
Glendora, a city of 50,000, also provided sandbags for residents at local fire stations and other places. More than 7,000 had been handed out, City Manager Chris Jeffers told the San Gabriel Valley Tribune (http://bit.ly/1eFNYmt ) on Tuesday.
The Verti family spent the past few weeks placing 200 sandbags and planned to place another 300 to protect their landscaped backyard, which includes a koi pond.
"We have 33 koi fish imported from Japan, and they all have names," Tom Verti told the newspaper. "We're going to buy portable tubs and fill them with water, but where do we put the tubs? This all could get inundated with mud."
His wife was more philosophical.
"We set up sandbags along the garage, plywood against the fence and now sandbags here (along the road)," Lizette Verti said. "We're going to stay, and if it floods, we'll just get some food and the pets and go upstairs."
The National Weather Service also noted the potential for mud and debris flows from the burn area of the May 2013 Springs Fire, which scorched nearly 38 square miles of the Santa Monica Mountains as it burned from the edges of suburban homes down to the beach about 50 miles west of downtown Los Angeles.
Numerous other wildfires statewide left scarred landscapes over the past year, including a 400-square-mile area devastated by last summer's forest fire in and adjacent to Yosemite National Park in the Sierra Nevada.
A so-called Pineapple Express storm brought rain and snow to California earlier this month, and when it departed, the Sierra Nevada snowpack had grown but was still only 29 percent of normal.
"The big difference between the storm earlier in the month in California and the coming two storms is in the area it will effect," Ken Clark, an Accuweather meteorologist, said in an email. "Much of the rain that occurred with the storms early in the month was in the northern half of the state with only very small amounts getting down into the Los Angeles and San Diego area."
The second of the two storms will bring by far the heaviest of rain to Southern California, he wrote. "In fact as much, or more rain, may fall in parts of Southern California than fall, let's say, around the (San Francisco) Bay Area when all is said and done."
Downtown San Francisco is close to its February average of 3.86 inches of rain to date, but is 11.62 inches below normal for the rain year that began on July 1.
Downtown Los Angeles has recorded only 0.23 inch of rain this month, 3.05 inches below normal to date. The location has received only 1.23 inches since July 1, a deficit of 9.52 inches.
