Rain hits, but hillsides hold in burn areas

Riverside Press Enterprise – 11/26/08

 

Although rain is subsiding at least temporarily throughout the Inland area, a flash flood watch remains in effect until 10 p.m., mainly for recently burned areas near steep hillsides, according to the National Weather Service.

 

Rainfall was moderate to heavy overnight in the region and another band of rainfall is possible. Showers developing off the coast may move onshore after 7:30 a.m.

The wet weather, with more than one inch falling in some areas, has caused traffic issues throughout the area, but not widespread flooding that was feared in the wake of recent fires. Jack-knifed trucks, flooding and rockslides are slowing the morning commute throughout much of San Bernardino and Riverside counties, according to the California Highway Patrol Web site.

 

The most recent SigAlert was issued at 4:17 a.m. for a jack-knifed big rig that blocked the two left lanes of southbound Interstate 215 at the Santa Ana River bridge in Norco.

 

In the Sunnymead area of Moreno Valley, four to five inches of water was flowing across the westbound lanes of Highway 60 at 4:11 a.m. just east of Perris Boulevard. The Riverside freeway interchange had up to 10 inches of water flooding the fast lane earlier this morning where I-215 joins westbound Highland 91.A SigAlert remains in effect for the area.

 

And in the San Bernardino Mountains, large rocks were in the traffic lanes at 4 a.m. just below Crestline where Highways 18 and 138 join.

Last night's storm brought more than an inch of rain to Corona and Chino Hills, according to the National Weather Service and San Bernardino County Flood Control data.

 

But most areas of San Bernardino and Riverside counties were in the quarter-inch to three-quarter-inch range. According to the National Weather Service, rainfall amounts totaled 1.34 inches at UC Riverside, 1.02 in Corona, .53 at March Air Reserve Base, .37 in Pine Cove, .36 at Lake Elsinore and .21 in Palm Springs.

 

According to San Bernardino County data, accumulations reached 1.26 in Chino Hills, 1.2 in Wrightwood, .95 in Phelan, .91 in Ontario, .71 in Crafton Hills, .67 in San Timoteo Canyon, .63 at Calstate San Bernardino and .47 in Devore.

 

Weather on Thanksgiving Day is expected to be partly cloudy, with the possibility of some showers moving through the region, though rainfall coverage and accumulations should be far less the half-inch to one inch of rain was said to have fallen by 3 a.m. today in western San Bernardino County.

 

Saturday through Monday will bring gusty winds blowing down from mountain passes.

 

High temperatures today and Thanksgiving Day are expected to be in the mid-60s in the valleys, the 40s to low 50s in the mountains, and the 60s to low 70s in the Low Desert.

 

At 7 a.m., Palm Springs was reporting 55 degrees. Most Inland valley communities also were in the 50s, ranging from Temecula and Murrieta to Wildomar and Perris north to Corona, Riverside, Moreno Valley and San Jacinto.

 

In the mountains, Angelus Oaks and Pine Cove were in the low 40s. #

Storm evacuations ordered in OC as rains hit

The Associated Press – 11/26/08

 

YORBA LINDA, Calif. -- New mandatory evacuation orders have been issued in wildfire burn areas of Yorba Linda after hours of rain have brought increased fears of mudslides in Orange County and across Southern California.

The Orange County Fire Department called for the evacuation Wednesday morning of at least 1,500 people in the Box Canyon, Brush Canyon, and San Antonio Fairmont areas of Yorba Linda.

 

Fire Captain Greg McKeown says no mudslides or debris flows have been reported yet, but that rain levels met a threshold that prompted the evacuations.

Voluntary evacuations had already been called for in the area, which was torched by the huge Freeway Complex fire earlier this month.#

Yorba Linda residents resist evacuation despite debris flow warnings

Los Angeles Times – 11/26/08

By Susannah Rosenblatt, staff writer


In neighborhood after neighborhood, hardly anyone in Yorba Linda's fire-ravaged areas seemed to be heeding Tuesday's voluntary evacuation order. But they sure were ready: on Lotus Avenue in the Box Canyon area, nearly every single home was bunkered with sandbags piled three deep lining the driveways and garages.

The evacuation order went out early Tuesday to residents in the Box Canyon, Brush Canyon and North Fairmont-San Antonio neighborhoods hard hit by wildfires. Officials fear the burned hillsides are the most vulnerable to mud and debris flows from Chino Hills State Park.

 

An evacuation order was also issued late Tuesday in Santa Barbara County for residents in the Tea fire burn area, including Sycamore Canyon. An evacuation center was being set up at Santa Barbara High School.

The Tea fire, the first in a ravaging series of brush fires, burned hundreds of homes in and around Montecito.

The blaze that swept through Yorba Linda destroyed or damaged more than 180 homes in the north Orange County city and blackened the steep hillsides.

Despite the evacuation order, Erik Irwin, for one, wasn't going anywhere Tuesday. The 20-year-old had hiked back into his Yorba Linda neighborhood during the fires against authorities' orders, where he wielded a garden hose to help protect his parents' house from spot fires just feet away. Nearby, a maintenance shed had burned to the ground.

"There's no way they're going to make any one of us leave," he said of his neighbors. He and another neighbor analyzed the slopes, theorizing what direction flowing mud might take.

"To tell you the truth, I'm getting really tired of the natural disaster stuff."

The racket from city crews installing a concrete barrier at the base of the hillside kept some residents up overnight. By Tuesday midday, a swift water rescue unit from the Orange County Fire Authority surveyed the neighborhood, asking residents about previous flooding problems. The unit was working to identify possible trouble spots and provide a presence in Yorba Linda and Santiago Canyon, said Capt. Jack Perisho.

Around the corner, Stuart Nichols was piling sandbags against the base of his garage. The consultant, who lives on Foxtail Drive -- also exposed to burnt slopes -- said his family was staying put for the moment but had a few overnight bags packed just in case. They were also taking keepsakes, such as their children's baby pictures, to a friend to store.

The city, Nichols said, "didn't respond very well when the fires came." With the well-publicized mudslide warnings, "they're trying to overcompensate, over-communicate."

The family had planned to go to Havasu for the holiday but was probably going to scuttle that trip because of the forecast.

"I'm ready for 2008 to be done," said Nichols, 44.

Brian Janney was still heading to see in-laws in Sacramento for Thanksgiving, debris flows or no.

"I'm definitely nervous to be leaving," Janney said as he packed the family's Suburban and his small son and daughter played in the yard behind him. But he's confident neighbors on the tight-knit Lotus Avenue will keep him posted. He stayed behind during the fires to keep an eye on his and others' houses.

Some neighbors said volunteers helped distribute the heavy bags Saturday. Late Tuesday morning a couple of residents loaded sandbags piled in the community park into their trucks and SUVs.

The Janneys have invited another family whose house was destroyed in the fire to use their home for the long holiday weekend.

In the Brush Canyon area, also under a voluntary evacuation, a crew of prisoners led by firefighters lined backyards with thousands of sandbags. Some created flood channels between houses to divert mud into yards. Workers with earthmovers pushed concrete barriers into place to direct the rainwater away from homes.

Residents there expressed a sense of evacuation fatigue, with many having returned from fire evacuations just over a week ago. Unlike the wildfire response, the city seemed to be throwing resources into massive preparation for the expected storm, some neighbors there said.

A few Brush Canyon residents said they had packed a bag or made a hotel reservation to be safe but weren't planning on leaving unless the hillside gave way.

A small sign on one Brush Canyon corner read "God bless our neighbors for protecting our homes! Thank you!!"#

Storm puts fire-scarred Southern Calif. on edge

Associated Press – 11/25/08

LOS ANGELES (AP) — Southern Californians living near areas scarred by recent wildfires sandbagged around their homes and in some places were urged to leave them Tuesday as a storm approaching from the Pacific brought a threat of floods and mudslides.

 

Gov. Arnold Schwarzenegger ordered state agencies to prepare to aid local organizations in case of disaster.

 

"The state stands ready to help local governments protect lives and property," he said.

 

A low-pressure area about 700 miles off the coast was heading northeast and could bring an inch of rain through Thanksgiving and up to 4 inches in the mountains, said Stan Wasowski, a forecaster with the National Weather Service in San Diego.

 

Flash flood watches were posted through Wednesday evening for areas where grass and brush that normally anchors the soil, helping to prevent mudslides, burned away. Some places could get a half-inch of rain in an hour, the Weather Service said.

 

A series of wildfires stoked by Santa Ana winds damaged or destroyed about 1,000 homes this month in Los Angeles, Orange, Riverside, Santa Barbara and San Bernardino counties. Those burn areas equaled a total of about 65 square miles.

 

In addition, October wildfires burned dozens more homes and scorched a total of more than 35 square miles. Other areas remain scarred from additional fires in recent months and years.

 

In Orange County, voluntary evacuations were in effect for three burned areas of Yorba Linda, a city of about 65,000 residents southeast of Los Angeles. More than 135 members of the California Conservation Corps were sent to canyons in Yorba Linda to place sandbags and clean out culverts and spillways to handle runoff.

Crews placed lines portable concrete barriers below the denuded hillsides of Chino Hills State Park, 90 percent of which burned, to redirect potential storm flows away from homes.

 

A call also went out for volunteers to fill sandbags in Sierra Madre, a hideaway Los Angeles suburb at the foot of a fire-stripped section of the steep San Gabriel Mountains.

 

City Hall was literally flying a yellow flag — the second-highest level in its mud-flow forecast system — to alert affected citizens to be prepared to leave their homes.

"After our April and May fires, we knew the next step would be mud, and we started preparing right away," said city spokeswoman Elisa Weaver. "We wanted to be able to warn people to be ready."

 

Without the fire-related risks, rain might be appreciated in parched Southern California. Downtown Los Angeles had recorded only 0.27 inches of precipitation since the July 1 start of the rain year — 1.35 inches below normal for this time of year.

 

Northwest of Los Angeles in Santa Barbara County, residents living below burn zones were warned to be prepared to leave. Mist had started falling by early afternoon, county spokesman William Boyer said.

 

"There are still many homes that are intact and directly in the burn area," Boyer said. Flooding and mudslides would pose a risk "directly to those homes that survived the fire," he said. #

Thanksgiving commuters: flooding causing local, state road closures

Desert Sun staff and wire services – 11/26/08

 

The overnight rains have flooded some streets in the valley, including just south of the I-10 freeway at Date Palm and Vista Chino in Cathedral City.

 

Drivers heading south on Date Palm should use caution when making a right hand turn onto Vista Chino. A sign warning of flooding is posted, but you'll make a big splash - and your windshield will be temporarily obstructed - if you take the corner too quickly.

There are flood signs up on Dinah Shore Drive near the bridge in Cathedral City, but the roads were not flooded as of 7:45 a.m.

The storm soaking much of Southern California has flooded Interstate 5 in San Diego, forcing the closure of the freeway’s northbound lanes for hours in the worst of several traffic-tangling shutdowns in the region.

The California Highway Patrol says it closed all of the northbound lanes at Palm Avenue at 2 a.m. Wednesday after at least two vehicles hydroplaned in a few feet of water and crashed. By 5 a.m. the CHP opened one northbound lane, but three remained closed.

Snow fell at the Palm Springs Aerial Tram Tuesday night, Lena Zimmerschied, public affairs manager for the tram, said Wednesday morning.

"We got a half of inch of snow," she said.

This is the second snowfall of the season for the tram.

Zimmerschied said the weather service is forecasting a chance of snow through Wednesday night.

"We're hoping for more," she said.

To the north in Los Angeles County, all southbound lanes except the carpool lane of the 110 Harbor Freeway were closed just north of the 91 Freeway for at least an hour because of flooding.

The Pacific storm system began dousing the county with moderate to heavy rain early this morning and was expected to continue generating rainfall until tonight, according to the National Weather Service.

The NWS issued a flash flood watch through tonight, when the storm is expected to taper off. In the meantime, residents living below burn areas were urged to keep track of flood warnings.

A weaker storm could bring a few lingering showers Thanksgiving Day, the weather service reported.

Much cooler weather was also forecast for this week, with a possibility of snow in the San Bernardino mountains today.

Today's forecast also called for temperature highs to peak in the 60s in
the valleys and in the 50s in the mountains.

Thunderstorms accompanied by small hail are possible today as cold air
aloft moves into the area, according to the weather service.#
