    A flooded field is more than just a rain delay—it’s a hazard. ✅ Always follow instructions from public safety officials and venue staff. 🚫 Never walk or drive through floodwaters; you can’t see what’s hiding beneath the surface or how deep the water really is.
    Flood Safety during outdoor events: Don't step into floodwaters. They hide dangers that can cause sickness, injury, or even death. Follow instructions from public safety officials and venue staff. NEVER drive through floodwaters. You don't know how deep the water is.

    Hot and dry weather combined with increasing winds will allow elevated fire weather conditions to return to the northern Intermountain West Friday into the weekend. Stay Weather-Ready and protect yourself from wildfires, visit weather.gov/wildfire
    Everyday Wildfire Prevention. Most wildfires are caused by humans - many everyday things can create sparks. Keep ignition sources far away from dry vegetation, wood, and other fuel. Have a clear 10 foot radius around campfires, burning brush, etc. Never leave fires unattended, and always properly extinguish. Use grills and smokers on gravel or paved surfaces. Never toss lit cigarettes on the ground. Put ashes in a metal container with a tight lid. Keep water stroed near campfires, fire pits, grills, smokers, burning brush, etc. Maintain vehicle brakes & tires, and secure tow chains to avoid dragging. Don't drive on dry grass or brush. Water your lawn and keep grass cut. Mow lawn early in the morning and when it's not windy or excessively dry. Always follow burn bans and regulations. Be aware of weather conditions. Low humidity, heat, drought and winds are conducive to fires.
    Protect yourself from wildfire smoke. Stay indoors and keep windows closed. Keep your pets indoors too! When using air conditioning, keep the outdoor air intake closed and clean the filter to prevent outdoor smoke getting inside. If you go outside, avoid exertion and consider wearing a respirator (N95 or P100 mask). Monitor the air quality for your zip code at airnow.gov
