Hiking tips

Thermal Safety Tips and Resources – YubaNet

The heat dome moving over California will bring record high temperatures this holiday weekend and beyond. The National Weather Service has issued an excessive heat warning for most of the state, with daytime temperatures in the triple digits and nighttime lows of 70 to 80 in the Foothills. Long-lasting heat impacts will persist at least through Tuesday, possibly longer. We’ve compiled tips and resources to help you stay as cool and safe as possible.

NWS Insights

Bill Rausch of the National Weather Service in Sacramento spoke at the Cal OES briefing today. “We are looking at a high confidence extreme heat event covering much of California. The heat is already rising in Southern California and it will push north and by this weekend and early next week it will cover the majority of California. This is an extreme heat event for several reasons. The temperatures themselves are ten to 20 degrees above normal during the day. Also, overnight recoveries are going to be very unusual. We all know it’s time for the body to recover and it’s not going to happen. Also, there will be a chance of all-time and monthly bests. We don’t expect much of that, but several stations have a chance of hitting all-time highs, which of course isn’t good.

In a separate briefing, the NWS also shared the outlook for very low relative humidity (RH) values. Given the excessive heat and dry fuels, if a fire were to break out, it could certainly grow quickly.

Health risk

During a Cal OES briefing today, state public health officer Dr. Tomás Aragón stressed the importance of staying cool, hydrated and informed. “When it comes to heat-related illnesses, the people most at risk are the very young, the very old, and those with chronic conditions, especially if they’re taking a medication that can make it more difficult to regulate their heat. temperature. .” He added, “housebound people, homeless people, as well as some workplaces where they may not have good air conditioning. An important thing for everyone is to please check your neighbor and to check on your colleagues.

“A lot of places don’t have air conditioning. So it’s important that these areas really remind people, even though normally the temperature here is not high, when you have a heat wave you have to be that much more careful. The other things people need to think about are cars. Don’t leave children and pets in cars, that’s really essential,” Aragón continued.

Leisure and events

Aragón spoke about the risks associated with outdoor events or recreation, from a health perspective: “You can have a sporting event where you have tens of thousands of people baking in the sun outside. Across the state, people hosting special events really need to think carefully and have a plan for how they are going to handle the people who attend their special events. What happens with heat waves? People can really decompensate pretty quickly, especially if they drink alcohol and have direct access to sunlight. People can get very sick. Often people talk about things like heatstroke when your body is unable to regulate temperatures, usually when the temperature is over 103 degrees Fahrenheit and people start having changes in their mental state, they become confused, which affects their judgement. They don’t realize they’re getting into trouble and that’s a real problem, especially if they’re alone. They may be on a hike. We know of situations where people are hiking and it happens and they don’t know they’re in trouble. And of course a passionate exhaustion.

  • Limit your alcohol consumption, rather drink plenty of water.
  • If you plan to hike or bike, consider shortening the distance or even postponing your hike.
  • Walk your pets early in the morning when the temperatures are coolest. Asphalt and even bare dirt heat up quickly and can damage your pet’s paws.
  • If recreating on public land, please observe all fire restrictions. Any outbreak of fire can quickly turn into a major incident.
  • Hydrate.


  • Adequate hydration is of the utmost importance. Take breaks from any activity and stay hydrated.
  • Make sure your pets have fresh water
  • If you can, put out water bowls for birds and critters. Be sure to keep the water clean.
  • Hydrate.

Prepare for power outages

With Enhanced Power Safety Settings (EPSS), power lines in your area are instantly shut down when struck by a branch or object. To reduce the risk of ignition, lines remain off until fully inspected and safely energized.

  • In rural areas, power outages affect wells if no generators are installed.
  • Get cash in case stores can’t process your bank cards due to a power outage.
  • Hydrate.

Automotive Safety

  • Keep the car’s gas tank full, in case of fire you want to be ready to evacuate.
  • Do not park in tall grass, catalytic converters get extremely hot.
  • If you tow a boat or a trailer, avoid dragging chains which can start a fire. Inspect the trailer’s brake lights and turn signals.
  • Hydrate.

Know your zone and make it a spark-free zone

  • In the event of an emergency, your area may be subject to an evacuation warning or order, or you may be asked to shelter in place. Find your zone for Nevada County here.
  • Now is not the time to use equipment that can start fires. Mowing in triple-digit heat isn’t just detrimental to your health, it can start a fire faster than you can say “Oops.”
  • If you are a barbecue enthusiast, plan a safe and unobstructed space around your cooking area.
  • Hydrate.

stay cool

  • Counties and cities will open a cooling center and we will add them to the list.
  • Local businesses will happily let you cool off while you shop, a win-win for all.
  • If you are lucky enough to have air conditioning, pre-cool your home early in the morning. As the outside temperature rises, raise your thermostat and circulate the pre-cooled air with a fan.
  • Close windows and blinds on the sunny side of your house.
  • Avoid using major appliances like stoves, ovens and dishwashers during the heat of the day.
  • Hydrate.
