From the destructive Dragon Bravo Fire in the Grand Canyon to smokey skies in the Northeast due to Canadian wildfires, discover how drought and fire are impacting the U.S. this summer.

Drought and wildfire interact in numerous ways. Many of the conditions that cause worsening drought can increase wildfire potential. Temperature, soil moisture, humidity, wind speed, and fuel availability (vegetation) are all factors that interact to influence the frequency of large wildfires. When fire sparks in an area that is in drought, drought can affect the intensity and severity of the fire. For example, rapidly drying abundant fuels in forest understories and grasslands after a wet spring can feed larger fires.

This summer, hot and dry conditions are driving large wildfires in the Western U.S. Check out the 11 maps below to better understand the conditions underlying current large fires and what’s forecast for fire and drought in the coming months.

Current Conditions

Large Fires Burning in the West

Large wildfires are burning in the Western U.S. Many of these areas are also in drought, according to the U.S. Drought Monitor. The largest uncontained or partially contained fires are currently the Dragon Bravo Fire (130,520 acres) burning in Grand Canyon National Park in Arizona, the Gifford Fire (83,933 acres) in Southern California, and the Bear Creek Fire Group (73,197 acres) in east-central Alaska, according to InciWeb.

Large wildfires are burning in every Western state except for Hawaii. Extreme or Exceptional Drought (D3/D4) is present in Arizona, New Mexico, Colorado, Utah, California, Nevada, Idaho, Oregon, Washington, Montana, Texas, Florida, and Hawaii. — This map shows active large wildfires from the National Interagency Fire Center (NIFC) Incident Management Situation Reports, alongside current drought conditions from the U.S. Drought Monitor.

Dry Conditions in the Southwest, Southeast, and Northeast

Evaporative demand is a measure of the potential loss of water from the land surface due to atmospheric factors. Periods of high evaporative demand are connected to droughts and increased fire danger. Over the last month, the Evaporative Demand Drought Index (EDDI), showed evaporative demand was high in the Southwest, western Oregon and Washington, South Florida, and the Northeast.

Above-normal temperatures, clear skies, high wind speeds, and low humidity increase evaporative demand, which leads to quicker drying at the surface. Reduced soil moisture leaves less water available for plants. When extended periods of low precipitation overlap with extended periods of high evaporative demand, vegetation can become critically dry and support rapidly spreading wildfires.

Evaporative demand was high in the Southwest, Western Oregon and Washington, South Florida, and the Northeast. Evaporative demand was low in parts of Texas, Oklahoma, Kansas, Nebraska, Montana, and eastern New Mexico — The Evaporative Demand Drought Index (EDDI) is a drought monitoring tool that shows the anomaly in daily evaporative demand over a given period of time—in this case, the past 4 weeks. Evaporative demand is the atmospheric influence on the drying of the landscape, or "the thirst of the atmosphere." Unusually high evaporative demand can lead to moisture stress on the land surface, and ultimately to drought—even when precipitation has been near-normal. EDDI can offer early warning of agricultural drought, hydrologic drought, and fire-weather risk. Map: drought.gov Data Source: NOAA Physical Sciences Laboratory

Smoke Reducing Air Quality Across the U.S.

Wildfire smoke can negatively impact air quality and harm human health. A number of large wildfires are burning in the Canadian provinces of Manitoba and Saskatchewan. Much of the U.S. is currently exposed to wildfire smoke, as smoke from these and wildfires in Colorado and California is drifting across the Nation. Air quality is particularly poor in the Upper Midwest, Northeast, northern Colorado, and southern California.

The U.S. Air Quality Index (AQI) is designed to communicate whether air quality is healthy or unhealthy. When air quality reaches unhealthy levels in your area, the Centers for Disease Control and Prevention recommend keeping outdoor activities light and short and heading indoors to cleaner air if you experience symptoms. Groups sensitive to air pollution should avoid the outdoors all together.

Air quality is particularly poor in the Upper Midwest, Northeast, Northern Colorado, and Southern California, which are experiencing conditions that are unhealthy or unhealthy for sensitive groups. Moderate air quality is present in the Southern Plains, other parts of Colorado, and in the Central U.S. and Mid-Atlantic. — This map shows observed air quality conditions based on fine scale particulate (PM2.5) concentrations. Green dots indicate healthy air quality, while yellow, orange, and red dots indicate progressively hazardous air quality conditions. Map: AirNow Fire and Smoke Map.

Smoke plumes are covering most of the U.S., except the Northwest and Southeast U.S. The heaviest smoke conditions are in Southern California, Kansas, the Upper Midwest, and the Northeast. — This map shows fire locations from incidents and satellite detections and smoke plumes detected by satellites. Grey shading indicates smoke plumes. Fire locations are represented as blaze icons. Map: AirNow Fire and Smoke Map.

Elevated Risk of Post-Fire Debris Flows in Parts of the West

Fires create danger after the burn, too. After a wildfire, communities and watersheds may face dangerous debris flows. Post-fire debris flows can occur in the years immediately after wildfires in response to high-intensity rainfall events. These debris flows are a danger to human life. They can occur with little warning and can carry enough force to damage structures, strip vegetation, and block drainage ways. Fires also alter watersheds and can reduce available water supplies for communities due to water quality problems in burned areas.

The U.S. Geological Survey (USGS) Post-Fire Debris Flow Hazard Assessment Viewer allows users to view or download post-fire debris flow hazard assessment data. The points on the map show the burn area locations where the USGS conducted hazard assessments from 2023-2025.

Debris flow risk assessments are available for several mountainous areas in the Western United States that recently experienced wildfires. — The map above depicts areas that have been assessed for post-fire debris flows in the last three years. Click the image to view an interactive map that can display the likelihood and potential volume of debris flows as they exit the mountain front in response to a storm with a 15-minute peak rainfall intensity of 24 mm/hour. The models are designed to assess the potential for debris flow in the locations where debris flows form and get larger. Map: U.S. Geological Survey Post-Fire Debris Flow Hazard Assessment Viewer.

Dry Vegetation in the West, Southeast

Dry vegetation is one factor that influences how large and damaging a wildfire becomes. Currently, the Vegetation Drought Response Index, VegDRI, indicates there is dry plant matter across the Western U.S., in the Southeast, and in northern Illinois. This area of dryness in Arizona underlies the Dragon Bravo Fire burning in Grand Canyon National Park and surrounding areas.

Vegetation is dry and stressed across the West, but particularly in Arizona and western New Mexico. Vegetation is also dry in the Southeast U.S. — The Vegetation Drought Response Index, VegDRI, depicts vegetation stress in the contiguous United States based on climate related variables and vegetation conditions measured by normalized difference vegetation index (NDVI). Orange and red hues indicate vegetation stress.

Looking Ahead

Fire Weather Tomorrow in Parts of the West

Critical fire weather conditions are forecast in parts of Wyoming, Colorado, Utah, and Nevada tomorrow. Elevated risk is predicted west of the Rocky Mountains from southern Montana to Arizona. Isolated dry thunderstorms are predicted in the Four Corners region.

The National Weather Service's Storm Prediction Center produces daily fire weather outlooks, which delineate areas of the continental U.S. where pre-existing fuel conditions, combined with forecast weather conditions, will result in a significant threat for the ignition and/or spread of wildfires.

Critical fire weather conditions are forecast in south-central Wyoming, northwest Colorado, much of Utah, and east-central Nevada tomorrow. Elevated risk is also predicted for these states in areas surrounding critical fire risk, along with a sliver of southern Montana and northeast Arizona. Isolated dry thunderstorms are predicted in the Four Corners region. — The National Weather Service's Storm Prediction Center’s daily fire weather outlook for August 7, 2025, which shows areas of the continental U.S. facing a significant threat for the ignition and/or spread of wildfires.

Extreme Heat Expected This Week in the Southern Half of the U.S.

Temperature is one of the key factors in determining how wildland fires start and spread. Temperature affects the flammability of forest fuels, since the amount of heat required to raise the temperature of the fuels to the ignition point depends on their initial temperature and that of the surrounding air. Temperatures can also influence the way fires spread and how quickly fuels combust. Hazardous heat is predicted later this week in the Southern Plains and portions of New Mexico and Arizona.

This National Weather Service Day 3–7 Hazard Outlook map shows the risk of hazardous heat 3 to 7 days from now. A hazardous heat risk area typically indicates a 40% or greater chance of exceeding National Weather Service Heat Advisory criteria, based on the Heat Index for your location, or widespread major (level 3) or scattered extreme (level 4) HeatRisk.

Hazardous heat is predicted later this week in portions of much of Kansas and Oklahoma into North Texas and New Mexico. Hazardous heat is also expected in southern Arizona. — This National Weather Service Day 3–7 Hazard Outlook map shows the risk of hazardous heat (red) 3 to 7 days from now (August 8–12, 2025).

Potential for Large Fires Continues in the West and Hawaii

Above-normal risk of significant wildland fires is forecast in Hawaii and much of the West, as well as a portion of the Southern Plains this month, according to the National Interagency Fire Center (NIFC). In September, this risk is reduced to Hawaii and areas west of the Rocky Mountains.

Above-normal significant wildland fire potential indicates a greater than usual likelihood of significant fires, which are fires that require mobilization of resources from outside the fire event area.

Hawaii is likely to see above-normal potential for significant wildland fires from now through the end of October, according to the National Interagency Fire Center (NIFC). NIFC also predicts above-normal risk of Wildland fires in much of the West and a portion of the Southern Plains this month. A small portion of Northern Montana has below-normal risk of significant wildfire. In September, this risk is reduced to areas west of the Rocky Mountains, and in October risk of significant wildland fires is further reduced to portions of coastal California and Oregon. — The outlook identifies areas by month for the next four months with above-normal (red), below-normal (green), and near-normal (white) significant wildland fire potential.

Seasonal Outlooks Favor Warm Conditions Across The Nation

Seasonal outlooks favor conditions conducive for wildfire in much of the Western U.S. The Lower 48 and Alaska are favored to see above-normal temperatures over the next three months. Portions of the West and North Central U.S. lean dry over the next three months.

Above-average temperatures are favored across the United States over the next 3 months. The interior Western United States, South Florida, and the Northeast have the greatest odds of above normal temperatures. — This map shows the probability (percent chance) of above-normal (red hues), near-normal (gray hues), or below-normal (blue hues) temperatures over the next three months. White areas indicate equal chances of above-, near-, or below-normal temperatures. Map: drought.gov. Data Source: NOAA NWS Climate Prediction Center.

Dry conditions are favored in the north central US and interior Western United States with the greatest chances for dry conditions in Southeast Montana, eastern Wyoming, northern Colorado, Western South Dakota and Western Nebraska. Wetter conditions are favored in much of the Eastern U.S. from the Ohio River Valley east to Atlantic Coast and from New York south to Florida and Louisiana. — This map shows the probability (percent chance) of above-normal (green hues), near-normal (gray hues), or below-normal (brown hues) precipitation over the next three months.
