[UPDATE 10:02 a.m.] Winter Storm Warning in Effect for the Mountains: Here’s What We Know About the Roads and Weather

We’re possibly heading back to wintery weather again. This morning there is a winter storm warning across much of northwestern California.

Be prepared for snow when traveling on Hwy 199, Hwy 299, Hwy 3, and Hwy 36. The snow may even reach Hwy 101 south of the Humboldt County line on Sunday according to the National Weather Service.

As of 8:20 a.m., none of the regular mountain passes show snow, however. Here is what we do know about the roads at this point. As more information comes in, we’ll update in blue.

Thank you for driving safely. Road sign, traffic

  • Well looks like climate change is over the climate has changed back . I guess we can do away with the EPA now do away with all the silly environmental regulations that are costing taxpayers billions . Oh but it’s already too late for Chico college they were already forced to take a cutting torch to all their heavy equipment that they had for teaching heavy equipment operating in heavy equipment repair California air resources Board literally made them cut it up every piece of equipment and replace with new California air resources Board approved equipment I am talking about bulldozers backhoes excavators bobcats yet the media refuses to report on this environmental madness . The madness that is putting hundreds of families in California out of work because of the California truck and bus rule requiring them to retrofit their equipment at $70,000 per . I am talking about heavy highway trucks that are 2010 or older owners are being forced to destroy these trucks in California as of January 1 of this year . Just Google California air resources Board destroying California

    • Also banning lead ammunition which in it self isn’t such a big deal but in ca non lead ammunition is considered armor piercing and illegal out of a rifle

      • Lead was banned because lead shell casings are reloadable. The UN was bribing officials to switch over to all non-reusable casings. In light of the UN’s horrific assaults on women & all citizens in general, plus their uncontrollable love for wars & full control over all countries, the repealing of the lead ban is the sanest repeal I’ve seen in years.
        Those who can’t believe how disgusting the UN really is, need to talk to the people in the countries who have been terrorized by them.

    • The epa twisted the data to suit their poverty agenda. The scientists who performed the studies, had to fight tooth & nail to get the truths of the studies out to the public. The powers that be, slandered, fired, silenced them while promoting the twisted up conclusions. The scientists have fought the epa every step of their miserable lieing way. The epa even went so far as to try to prove their own conclusions, by alledgedly performing unconstitutional tests on real live people. Fortunately, the scientists were correct, & the people didnt die.

    • Climate change is erratic. We can switch back to drought next year.

      • Ice ages, droughts, famine, all happens and always will we are just along for the ride maybe we help it come quicker maybe we don’t, either way it’s going to happen, Mother Nature always does whatever the hell she wants

    • The Hermit of Grizzly Mountain

      The space angels say the CO2 cover-up began with Reagan & Thatcher 1983, before Gore took up the cause:

  • Hwy 36 is down to controlled one way between Wildwood and Platina because of a slide.

  • Read some books with the actual science of climate change. The models are actually pretty simple once you see how ocean currents move and how temperature/fresh water influx affects the weather. Its how the whole “engine” works. You cant drain the oil and have no antifreeze in your car engine and expect it to work correctly.

    This winter is closer to normal weather but on steroids. All over CA. Theres been record breaking rain and snow levels. Atmospheric scientists have found that these are the highest CO2 levels since humans appeared on the planet.

    Lots and lots and lots of good science has been discredited and pushed into the shadows. Big companies want to make as much as possible and could care less about their impact so they get the studies thrown out.

    By next winter or the one after we are really going to see the effects as the majority of ice in the artic will be melted and ocean life will die off. The kelp is all dying right now, and the krill (which feed everything) depend on the algae that lives on the bottom of huge icebergs which are melting. Get ready! I talked with an atmospheric climatologist who works at JPL. This was around 9-10 years ago and he said we had 5 years before we hit the major point of no return. He was going to a meeting and said the officials wouldnt listen. If we stopped everything right now it would take 20 years to get back to some normal levels.
    The EPA has also been pushed away and treated like dummies. We had rivers catching on fire from pollution in the 70’s, and the epa regs helped those issues. But hey if you want to make sure your kids and grandkids get horrible cancers, go ahead and say the epa are idiots and enviro regs do nothing. We are doing zero to stop the spread of cancer causing materials. The companies polluting are the ones making the cancer treatments. Big money. Enjoy the final days, it wont be long now. Stash food and water and be ready for the whole countries infrastructure to fail. Once they frack off our coast theyll trigger the triple junction and a good part of CA will have massive quakes and potential slumping of large land mass into the ocean. Look at how big the quakes have gotten in Oklahoma from fracking there!

    • There’s no point to try and get your point across. Most Republicans just refuse to acknowledge the fact that science proves climate change is a real thing. Really it’s just sad for our children, and our children’s children. Them ignoring that will be our demise. It’s already projected when the sea level raises some 3 feet, millions will be left with out homes and billions of dollars worth of property will be flooded. And yes it’s also true that we can swing right back into a drought.

    • too many frigin people here anyways, I’m sure after we’re all eradicated the earth will heal itself, kinda like chemotherapy I guess, and yes fracking is fracking horrible

    • Thank you for your excellent comment.

  • Hermit of Livry

    Climate change is real. And God’s word plainly states the reason.

    “The earth mourneth and fadeth away, the world languisheth and fadeth away, the haughty people of the earth do languish. The earth also is defiled under the inhabitants thereof; because they have transgressed the laws, changed the ordinance, broken the everlasting covenant. Therefore hath the curse devoured the earth, and they that dwell therein are desolate: therefore the inhabitants of the earth are burned, and few men left.

    Isaiah 24

  • To Wwi – An excellent, well-reasoned comment. I took my first Human Ecology class in 1970. We participated in the First Earth Day 47 years ago. The book I used could be used for a class today regarding exactly the same issues. As a species, we refuse to be educated because education gets in the way of our own limited perceptions. And we refuse to believe that mother nature always bats last.

  • Wwi. Stop trying to scare everyone everyone knows that the government scientists are corrupt because the government is giving them the billions of dollars to do their phony research and everybody knows all the weather models are not accurate that has been proven over and over so what books and fax are you talking about . Also just like with California’s ridiculous truck and bus rule that requires all trucks 2010 and older be taken off of the road and that is current law . The scientist who produced all of the data to support California’s phony claim admitted to getting his degree at a phony online college but that’s a wholeother story . To Noaa . Cooking the books in changing the fax to meet the Obama administration’s wishes and preconceived climate notions Just before the last climate deal or climate summit so don’t tell me about government facts and science and reading some more bullshit books because the public isn’t buying it anymore. When people like you talk all I hear is blah blah blah . I mean really now they are going to go after Cow farts that is a fact with that kind of bullshit you people are losing credibility like crazy ! keep it up because you’re losing

  • Onrust you are sadly mistaken your god mother earth does not bat last !!!. God does!!! And more blah blah blah keep it up you’re losing

  • Honeydew Bridge Chump

    The sun drives climate, nothing else.
    We’re entering a solar minimum, low sunspots, this will last 15 years.
    Winters will be colder for some time above 30* latitude.

  • Yup
