36,000 Tahoe-area trees are dead or dying as California’s drought persists

Drought Emergency Alert

Of the millions of trees that are dead or dying as a result of California’s ongoing drought, about 36,000 are spread across forests in the greater Lake Tahoe-Truckee region.
 
A U.S. Department of Agriculture report published March 2015 shows that of more than 44 million acres surveyed in California, the tree mortality rate in 2014 more than doubled from the previous year, with about 909,000 acres showing elevated mortality.
 
More than 10 million trees surveyed in Southern California’s Los Padres National Forest have been impacted by the drought and pine bark beetles, according to the report.
 
In total, the U.S. Forest Service estimates the current drought has contributed to the death of at least 12.5 million trees in California’s forests.
 
Of the more than 36,000 reported dead or dying trees in the Tahoe region, 30,370 were viewed within the Tahoe National Forest, which extends east of Sacramento, through the foothills and across the Sierra crest to the California state line.
 
The remaining 6,106 were viewed within the Lake Tahoe Basin, according to the report. In terms of area, the mapped mortality included about 6,331 acres of forest — 1,842 in Nevada County, and 4,489 in Placer.
 
“What is happening now, these small pockets are composed of larger trees,” said David Fournier, with the Forest Service’s Lake Tahoe Basin Management Unit.
 
Foresters and fire people call the dead trees “red trees,” Fournier said — whereas a healthy pine or fir tree will have its typical deep green color, aerial surveys conducted for the annual report show large swaths of forest taking on a brown or red hue.
 
Despite the fact California has been in this current drought since 2011, Fournier said the state never really recovered from the historic drought conditions in the early to mid-90s.
 
“Somewhere in the last nine years, (California has) not had a substantial winter, and in the last four years, it’s been nearly non-existent,” he said.

Huge hailstorm turns beach white in Southern California, USA

The beach at Southern California’s “Surf City” has been turned white by a dumping of hail from a fast-moving storm.
 
The National Weather Service says at least an inch of icy pellets coated the sand at Huntington Beach after the system roared ashore Monday morning.
 
Brianna Burkhart, who works at Duke’s restaurant on the city pier, says the sky suddenly turned dark and then opened up.
 
She says when it was all over the beach was completely white and it looked like it had snowed.
 
It’s the second winter storm to hit the area in several days. Over the weekend a smattering of hail was reported to the north on Venice Beach.
 
Plane pilots reported seeing funnel clouds over the ocean about 25 miles off Redondo Beach.

Severe Snowstorm Strands 180 Motorists In California, USA

Firefighters have rescued more than 180 drivers who were stranded during a winter storm in Southern California.
 
Emergency crews used snowmobiles to help 136 motorists who were stuck on a highway in the San Bernardino Mountains, about 70 miles (110km) from Los Angeles.
 
Another 50 marooned drivers were rescued near the Mount Baldy ski area.
 
The larger group of motorists were trapped in more than 1ft (30cm) of snow amid high winds on Highway 138.
 
Many of the drivers abandoned their cars and walked to their homes or nearby shelters.
 
At least 150 vehicles had to be towed off the road during the night’s operation, said California Highway Patrol.
 
Firefighters transported about 50 motorists to a church in the community of Crestline, where Red Cross workers provided aid.
 
Other motorists were able to drive away as snowploughs cleared the road.
 
No injuries or serious collisions were reported.
 
Rescue operations were completed by about 3am local time on Wednesday, the authorities said.
 
The National Weather Service forecasts further snow across the region, with even parts of usually balmy Los Angeles County expected to see up to 5in.

Unusual Snow Storm Is Heading For California, USA

Winter Storm

A storm and cold air forecast to develop at the end of 2014 and linger into the start of 2015 will deliver snow, rain and a frost or freeze to portions of California.
 
The coldest air of the winter months so far will settle over California during the middle of this week.
 
At the same time a storm will form nearby and bring snow and slippery travel to the passes of California.
While temperatures are not forecast to drop to record low territory for much of the state, the air will get cold enough, long enough to bring a frost and freeze to the Sacramento and San Joaquin valleys, as well as part of the central coast of California.
 
Record lows over much of the area range from the upper teens to the middle 20s during the end of December into the first part of January.
 
Temperatures are not forecast to drop as low as that of mid-December of 2013.
 
Temperatures are forecast to drop as low as the upper 20s to near 30 degrees for a couple of hours in agricultural areas during Wednesday night and Thursday night in central and northern areas of the state and Thursday night into Friday night farther south. This will follow near-freezing lows during the first part of the week.
 
The temperatures forecast pose a minimal threat to citrus crops in the region.
 
According to California Citrus Mutual (CCM), the rind on California citrus crops is thicker and offers more protection from freezing temperatures, when compared to those in Florida. Brief episodes with temperatures near or just below freezing contribute to a sweeter crop.
 
However, other flower, fruit and vegetable plants in the state, if left unprotected could be damaged.
 
While frosty and freezing temperatures will cause its share of concerns, snow will also visit the region.
 
Enough snow is forecast to fall on the passes of the state to cause slippery travel and delays.
 
While a few inches of snow forecast for Donner Pass will be a minor problem for crews and travelers on Interstate 80, even a small amount of snow can lead to major troubles for commuters over Tejon Pass on I-5 and Cajon Pass on I-15.
Snow is forecast to fall over the northern Sierra Nevada along with locally gusty winds on Tuesday and over the mountains of Southern California on Tuesday evening into Wednesday.
 
The storm will also bring some cold rain showers to Southern California. However, the amount of rain is not likely to significantly impact drought conditions in the region. Little to no rain is forecast in lower elevations with the storm over northern and central California.
 
When combined with brisk winds, Temperatures will dip into the 30s at times around Los Angeles and San Diego at midweek for New Year’s Eve revelers.
More significant rain and snow will fall farther inland over the Southwest. Up to a few inches of snow are forecast to blanket Las Vegas, with heavy snow likely in the mountains of northern Arizona, southern Nevada and the Four Corners region in general.

Record heatwave of 100F + in October is crippling California, USA

Temperatures hit 104F in San Fernando valley
 
Cycling enthusiasts brave scalding heat in downtown LA event
Heatwave Alert
“Stay safe!” went the mantra, as tens of thousands of cyclists zipped around Los Angeles this weekend for CicLAvia, an event to celebrate public spaces.
 
Fellow riders, pedestrians and police shouted it as much in greeting as exhortation since clearly the safest thing was to be indoors clutching an ice pack with your feet up and the air-conditioning blasting.
 
The danger, for once, was not motorists, or potholes, or muggers, but heat. Record, scalding temperatures fried the city and much of southern California with temperatures exceeding 100F, defying a calendar that said autumn.
 
Staying safe meant wearing a hat, drinking lots of water and seeking medical advice at the first sign of hallucinations. “Man oh man, hot!” howled one man, apparently happily, as he whizzed down the Broadway theatre district. A friend close behind mimicked the Wizard of Oz’s wicked witch: “Melting! I’m melting!”
 
The four-day furnace eased on Monday, with temperatures dropping to the low 90s, but another intense heatwave is due this weekend, bringing fresh risks of wildfires and power outages.
 
The San Fernando valley hit 104F (40C) on Saturday, making Pasadena’s 102F seem merciful, and Torrance’s 96F positively cool. Most Angelenos hunkered indoors, close to a fan or air-conditioning, or splashed in the sea, swimming pools and fountains.
 
On Sunday an estimated 50,000, however, participated in the annual CicLAvia, a cycling-centric event which closed streets around downtown and east LA.
 
There was little shade and you could have fried an egg on the tarmac but spirits were high. Evangelical Christians handed out water bottles with recruitment pamphlets – double salvation – while other bystanders used water pistols and hoses to spray the sweating, panting hordes. “Thank you, thank you,” we yelled, pedalling through the vapours.
 
The 2nd Street tunnel, usually a roaring darkness of engines and fumes, was transformed into an oasis of shade and clicking wheels.
 
“California has mistaken October for July. In the Sahara,” declared BuzzFeed, which compiled tweets from the frontline. “It’s so hot Superman just requested a black car from Uber!” said one. “Live tweeting myself bursting into flames,” said another. And: “Too hot for condoms.”
 
A high-pressure system over the western US, along with Santa Ana winds, which blow across deserts before hitting southern California, generated the heat.
 
Combined with three years of drought, which has turned many farms to dust, wilderness areas are a tinderbox. The US Forest Service and LA County fire department have bolstered firefighting crews and sent extra equipment to strategic locations.
 
“We’ve got wind, heat, the perfect combination, everything in alignment for a potential brushfire,” fire captain Rich Moody warned last week as he patrolled a southern California hillside.
 
A recent report in the Bulletin of the American Meteorological Society, which investigated 16 extreme weather events in 2013, found that human-caused climate change played a role in heatwaves.

Storm system off Mexico’s Pacific coast slams beaches with high surf causing flooding and closures in Southern California, USA

Severe Weather Alert

Southern California’s shores were slammed by high surf again Wednesday, the result of a storm system churning off Mexico’s Pacific coast. Several beaches were closed off to the public in Malibu and Rancho Palos Verdes after waves dislodged portions of a pier in Malibu and riptides snarled swimmers along the coast. Seal Beach, which sustained most of the damage Tuesday after several homes were flooded, avoided more water during Wednesday’s high tide, but officials say they expect the high surf to continue.

Major Hurricane Marie is a Cat 5 in the Eastern Pacific

Hurricane Alert

The National Hurricane Center announced today that Major Hurricane Marie is the first Cat 5 storm in the eastern Pacific in 4 years.  Take a look at the water vapor imagery…
wv_lalo-animated

That’s a beautiful hurricane!  At 8pm winds are 150mph and it’s about 475 miles SSW of the southern tip of Baja California.  So this storm will pose no threat to land in the form of wind, storm surge, or rain.  It will track well out to the west south of the upper-level ridge that is along the western USA coastline.

But the tremendous waves & swell generated by this storm are forecast to arrive along the beaches of southern California in about 48 

ww3-enp_epac_060_regional_wv_ht

The wave watch model above shows 9 meter waves, and the local NWS offices in California are warning of localized erosion, flooding, and some damage.  Of course I suppose the surfing will be great!

Up here in the Pacific Northwest it’s possible some of this moisture will enhance our showers next weekend.  Or it may stay to the south in northern California, or it may stay well offshore.  We’ll see.

The past few days there was another blowup in the comments.  It happens about every 6 months…yawn.  I didn’t even notice for the first two days because the weather is so slow, but then I see it got resurrected and brought into a new posting!  Geez, what is wrong with people!  I’ll be honest, I think at least 60% of the readers find it entertaining, at least that’s what I hear on the street and via emails.  In the past I’ve let it go a bit, or banned a few people for a couple months (last spring).  

But this time was a little different.  When the entire newsroom receives emails about it, then it becomes my problem, not just a few offended posters.   I’m not willing to damage my career or relations with my bosses over folks picking on other posters or someone going all “Mt. St. Psycho” with profanities and threats.   Or having drunk people on the blog posting about who knows what.  And really the only reason people went at it this time was because only this blog allows anyone to engage with others directly.  This was used as a battleground.  And Weather Daddy doesn’t like that!  As a result I’ve added 5 names to 2 others that are on “semi-permanent” moderation.  That means you can comment, but I have to hit the approve button.  Technically you are not banned from here, but I can’t trust you to not get out of control.  The sad part is that I actually enjoy every one of you and several of you bring really good info to this blog.  

So nothing personal, but it’s just too much chance that it’ll come back to haunt me at some point.  I’m cutting my losses ahead of time.

Remember that there are at least 2 good Facebook discussion groups here in the Portland area.
