    If a wildfire threatens your area, stay informed of evacuation orders. Leave immediately when asked to avoid being caught in fire, smoke or road congestion. Have an emergency supply kit in your vehicle and know your evacuation route. More: weather.gov/safety/wildfire
    "Evacuating From Wildfires: Always stay aware of your environment. Leave when asked by your local officials. Take Action Immediately: Leave as soon as evacuation is recommended by fire officials to avoid being caught in fire, smoke or road congestion. A delay could cost your life! Take the initiative to stay informed and aware. Listen to your radio, TV, or alerts on your phone for announcements from law enforcements and emergency personnel. Cover up to protect against heat and flying embers. Wear long pants, a long sleeve shirt, heavy shoes/boots, cap, a face mask, goggles or glasses. Ensure your emergency supply kit is in your vehicle. Enact your evacuation plan that includes the route you'll take and designated emergency meeting location outside the fire or hazard area.

    Dangerous fire weather conditions are expected across portions of the Great Basin and Southwest on Friday. Dry and windy conditions will allow any new or existing wildfires to spread rapidly. Stay alert to the forecast at weather.gov and follow instructions from
    Fire Weather Outlook for Friday June 26th from the Storm Prediction Center. Extremely Critical fire weather conditions are forecast for Utah and portions of southeastern Nevada and northwestern Arizona.
    Red Flag Warning infographic. A Red Flag Warning is issued when critical fire weather conditions are happening or about to happen. It does not necessarily mean there is a fire, but that conditions will be very dry and windy. If a fire is present, it can become extreme! Avoid activities that could spark a wildfire. Take action: make your wildfire plan with at least 2 evacuation routes, maintain your go kit, follow fire prevention tips and regulations, and listen to local officials for updates and evacuation orders.

    A robust fire weather pattern is expected across an expansive portion of the Intermountain West through the middle of next week. Dry thunderstorms on Wednesday/Thursday will be followed by multiple days of exceptionally dry and breezy conditions will promote significant fire
    Wildfires can escalate quickly. Wildfire growth can be terrifyingly sudden and deadly. Prepare ahead of time so you'll be ready. Clear brush away from your home to create defensible space. Use fire-resistant landscaping. Know your potential evacuation routes. Have an emergency supply kit ready to go.

    Even after the sun goes down, heat can be a real danger - especially in large cities. Dark pavement and buildings are very effective at absorbing heat. Stay Weather-Ready by always practicing heat safety, no matter the time of day. weather.gov/heat
    Excessive Heat: dangerous even after the sun goes down. Large cities often experience higher temperatures than surrounding areas because of all the heat-absorptive surfaces, such as dark pavement and buildings. This is known as an urban heat island. The upper floors of brick buildings are particularly susceptible to the dangers of excessive heat without air conditioning, because they retain heat after the sun goes down. The strong influence of the urban heat island on nighttime temperatures limits the ability of people to cool down and recover the heat of the next day.

    Areas of Major HeatRisk will expand into the Midwest Sunday through Tuesday with pockets of Extreme HeatRisk possible, particularly through the Mississippi Valley. This level of heat will affect anyone without adequate cooling or hydration. Low temperatures only dropping into
    NOAA graphic highlighting locations expected to experience record warm overnight low temperatures during a prolonged early summer heat event. Colored circles indicate timing of potential record warm minimum temperatures: red for Sunday morning, orange for Monday morning, and yellow for Tuesday morning. The greatest concentration of Sunday morning record warm lows stretches across the Southeast, including Georgia, South Carolina, North Carolina, and parts of Tennessee, with additional locations across New Mexico, west Texas, and southern Kansas. Monday morning record warm lows expand across Oklahoma, Arkansas, Tennessee, Florida, and parts of the southern Plains. By Tuesday morning, scattered record warm lows continue across portions of the Midwest, lower Mississippi Valley, Florida, and central Plains. The map illustrates persistent overnight heat reducing cooling relief and increasing heat stress across affected regions.

Major heat risk (red) covers large portions of the central Plains, lower Mississippi Valley, Southeast, and parts of the Midwest, including areas from Kansas and Oklahoma eastward into Georgia and the Carolinas. Extreme heat risk (purple) is concentrated in parts of Florida and localized areas of New Mexico. Moderate risk (orange) extends broadly across the southern Plains, Midwest, Gulf Coast, and interior Southeast, while minor risk (yellow) reaches into the Great Lakes, Ohio Valley, and Mid-Atlantic. Conditions may be dangerous for anyone without effective cooling or hydration.
    NOAA HeatRisk forecast for Monday showing expanding and intensifying dangerous heat across the central and eastern U.S. A large swath of major heat risk (red) stretches from the central Plains and Midwest southward through the lower Mississippi Valley and Gulf Coast, covering states from Nebraska and Iowa to Louisiana, Alabama, and Georgia. Extreme heat risk (purple) develops in portions of Florida, New Mexico, and isolated pockets in the central Plains and Midwest. Moderate heat risk (orange) extends into the Great Lakes, Appalachians, Texas, and the Southeast, while minor risk (yellow) reaches farther north into the northern Plains and Northeast. Prolonged heat exposure increases health risks, especially without cooling relief.

    Widely scattered severe thunderstorms should occur today across parts of the central High Plains with a threat for large to very large hail (some 3-4 inches in diameter), severe wind gusts, and a couple of tornadoes. The storms will likely develop by mid to late afternoon across
    NOAA Storm Prediction Center severe weather outlook for Wednesday, June 24, 2026, highlighting thunderstorm risk areas across multiple regions of the United States. The primary concern is over the central High Plains, where a broad slight risk (level 2 of 5) stretches from eastern Wyoming and Colorado south through western Nebraska, Kansas, and into New Mexico. Within that region, a smaller enhanced risk (level 3) is centered near northeast Colorado and southeast Wyoming, indicating greater potential for organized severe storms. A separate slight risk covers parts of Wisconsin and the Upper Midwest, while another smaller slight risk is centered over southern Idaho. Broader marginal risk (level 1) areas surround these regions, extending across much of the Plains, Midwest, Gulf Coast, Florida, and portions of the Northwest. Main threats include damaging winds, large hail, and isolated tornadoes.
