When weather conditions turn hot, dry, and windy, the risk of a single spark igniting a wildfire increases dramatically. During these periods of elevated fire danger, fire professionals and land management agencies rely on several tools to inform the public about the risk and outline actions that can help prevent human-caused fires. Terms like Red Flag Warning, stage restrictions, and burn bans are being used more frequently as prolonged drought, dry fuels, and extreme weather become more common. Just last week, parts of the Cibola National Forest and National Grasslands implemented Stage II fire restrictions, highlighting how quickly conditions can shift across the region. While these terms are often used together, they serve different purposes.
Below, we break down what each designation means, how they are determined, and the types of restrictions or precautions that may accompany each notice. By knowing why these measures are implemented, communities can make safer decisions, follow local regulations, and help reduce the risk of human-caused wildfires during periods of elevated fire danger.

Red Flag Warnings
What is a Red Flag Warning?
The origin of the name, Red Flag Warning, is a literal one, according to Tamara Wall of the Desert Research Institute: “If there was… high fire danger, local fire stations would go and run a red flag up the flagpole. It was a very visual, kind of pre-mass communications way to signal to people in the area that it was a high-danger day” (NPR, 4/14/23).
According to the National Weather Service (NWS), which issues these alerts in conjunction with local and state agencies, a Red Flag Warning is part of a weather forecast which indicates a local increase in fire danger risk in the next 12 to 24 hours. This increased risk is due to a combination of critical fuel conditions and critical weather conditions (warm temperatures, very low humidities, and strong winds). This means that if a wildfire starts, the conditions are right for it to spread rapidly and be difficult to contain.
This combination of 1. low relative humidity (RH), 2. strong surface wind, 3. unstable air (an incoming or outgoing storm system that creates a significant temperature differential between the land surface and lower atmosphere), and 4. drought creates critical fire weather (NWCG, Critical Fire Weather). When it comes to issuing a Red Flag Warning, primary criteria include relative humidity of 15% or less combined with sustained surface winds, or frequent gusts, of 25 mph or greater. Both conditions must occur simultaneously for at least 3 hours out of a 12-hour period, according to the National Weather Service. Meteorologists also consider how all forecasted weather elements combine to create hazardous conditions (e.g. moderate humidity combined with high temperatures and high winds), even if they don’t fit the humidity and wind criteria individually.
When you see a Red Flag Warning, it means that critical fire weather is currently or will soon be occurring. Red Flag Warnings differ in timing from a fire weather watch, which is a longer-term forecast that warns of the possible development of Red Flag conditions in the next 72 hours. Fire Weather Watches may be issued with meteorologists forecasting up to 8 days in advance, whereas Red Flag Warnings are only issued when the critical fire weather conditions meeting the criteria for these Warnings are expected to begin in the next 12-24 hours.
The alert announcing a Red Flag Warning, whether online, on the news, or on your weather app, will usually indicate for how long the Red Flag Warning is forecasted to last. Fire management personnel take Red Flag Warnings into account and may respond by changing staffing numbers or preemptively moving resources into a certain region to be prepared for a potential ignition. During extended periods of high risk, local authorities may consider policy decisions like banning campfires or closing specific areas.
How to Respond
Adjust your behaviors accordingly to avoid creating a spark that could ignite a larger fire.
DO NOT burn debris piles.
If you are allowed to burn in burn barrels in your area, cover them with a weighted metal cover.
DO NOT throw cigarettes or matches on the ground or out of a moving vehicle.
If outdoor fires are allowed, make sure to extinguish them properly. Drown fires and charcoal with plenty of water and stir with a shovel to make sure everything is cold to the touch with bare skin.
Never leave a fire or barbeque unattended. Sparks or embers can blow into leaves or grass, ignite a fire, and quickly spread.
Avoid parking a recently driven vehicle on dry grass or other areas with vegetative cover.
Ensure that no chains or hanging metal are dragging from your vehicle or tow-behind trailer which could cause a spark.
Fire Restrictions
What are fire restrictions?
In the U.S., fire stage restrictions are a set of regulations that come in three tiers to limit activities and possibly even access to segments of public land (e.g., a national forest or ranger district) during periods of high fire risk. Fire restrictions are put in place by land managers to reduce the risk of human-caused wildfire ignitions during periods of high fire danger and severe weather conditions. The decision to implement fire restrictions is based on various factors, including the availability of firefighting resources, current drought conditions, weather forecast, and fuel moisture levels. On national forests, managers may consider implementing restrictions if at least three of the following conditions are present: (1) 1,000 hour fuel content is in the 90th percentile or above; (2) three-day mean energy release component (a measure within the NFDRS that determines potential heat that could be released if fuel was burned, indicating a fire might be hotter and harder to suppress) is at the 90th percentile or above on the forest or district’s dominant fuel type , (3) live fuel moisture content is 75% or less, (4) wildland fires are impacting available suppression resource capacity; (5) the area is receiving a high occurrence of wildland fire, and (6) adverse fire weather is predicted to continue (NIFC, 2021).
Managers often coordinate with state, county, and federal partners to implement fire restrictions, but because different agencies manage different lands, restrictions may not always align across boundaries. For example, a national forest may be under restrictions while nearby county or municipal lands are not. It is worthy of noting, different agencies and entities may also use different criteria or require different approval processes to implement stage restrictions, so visitors should always check the rules for the specific area they plan to visit.
Below are the three stages of fire restrictions and the common prohibited activities initiated by these restrictions on federal lands. Local variations on prohibited activities may exist.
Stage 1
Stage 1 fire restrictions reduce wildfire risk while allowing limited recreation.
Typically prohibited (unless otherwise specified):
Building, maintaining, attending, or using campfires, charcoal grills, or other open fires except in designated, developed recreation sites
Smoking, except inside an enclosed vehicle or building, within a developed recreation site, or in an area at least three feet in diameter that is cleared of all flammable materials
Operating chainsaws or similar equipment without a USDA- or SAE-approved spark arrester
Welding or using acetylene torches or other open-flame devices outside of cleared areas (usually at least 10 feet in radius)
Discharging fireworks
Generally allowed:
Portable stoves, lanterns, and heaters fueled by propane or other liquefied petroleum fuels, provided they are used in cleared areas and meet manufacturer safety specifications with an on/off switch.
Stage 2
Lincoln National Forest Stage 2 Fire Restrictions - May 2025
Stage 2 fire restrictions further limit ignition sources during very high fire danger.
Typically prohibited (unless otherwise specified):
All campfires, charcoal grills, and open fires on federal lands
Smoking, except in an enclosed vehicle or building, a developed recreation site, or in a cleared, nonflammable area
Discharging fireworks or using explosives
Operating motor vehicles off designated roads (except in developed parking areas or trailheads)
Operating equipment powered by internal combustion engines (such as chainsaws) without a spark arrester, or using equipment that produces open flames (e.g., welding); some activities may be restricted to specific hours
Generally allowed:
Portable stoves and lanterns using gas, jellied petroleum, or pressurized liquid fuel, as well as fully enclosed wood-burning stoves with proper spark arrester screens.
Stage 3
While the stage restriction system is used for both public and private lands depending on the authorizing entity, stage 3 restrictions are only used on public lands. Stage 3 restrictions involve full closure of a forest or designated area. During a closure:
All roads, trails, and access points may be closed
Public entry and recreation are prohibited
All activities, regardless of type, are suspended until conditions improve
These closures are implemented only when fire danger is extreme and continued public access would pose significant safety risks or hinder firefighting operations.
Southwest Area Fire Restrictions Interactive Map
New Mexico Forestry Division put together a dashboard to provide the public with a real-time map showing current fire restrictions on public lands in the Southwest. Map data is compiled from various sources and mostly displays federal and state lands, with county restrictions reflected when provided. You should contact your local fire department or government agency for the latest fire restriction information.
Fines and Penalties
Once fire restrictions are in effect, violation of prohibited activities may result in citations, fines, or criminal charges. It is important to not however, that penalties may vary depending on the agency and jurisdiction enforcing the restrictions.
On lands managed by the U.S. Forest Service, violating stage restrictions is generally considered a misdemeanor. Penalties include a fine of up to $5,000, imprisonment for up to six months, or both.
Local jurisdictions in New Mexico may impose different penalties. For example, on county-managed lands in Los Alamos County, a person found in violation of fire restrictions may receive a written citation and face criminal penalties, but no explicit fine amount is listed in their order. In contrast, within the City of Albuquerque, violations of fire restrictions may be punishable by a fine of up to $500, imprisonment for up to 90 days, or both.
Burn Bans
Burn bans are another tool agencies and fire administrators use to prevent wildfires and protect public safety during dry weather and high-fire risk conditions. Burn bans, also known as open burning restrictions, are temporary regulations that limit or prohibit outdoor burning activities such as campfires, bonfires, burning yard waste, agricultural burns, and the use of fireworks. Depending on the severity of conditions, some bans may still allow certain low-risk activities, like cooking with propane grills or using enclosed stoves, while stricter bans prohibit nearly all open flames. Essentially, a burn ban means that outdoor burning is restricted or prohibited within a designated area to reduce the risk of accidental fires spreading.
Burn bans are typically enacted due to factors like drought, low humidity, dry vegetation, high winds, and elevated temperatures, all of which significantly increase wildfire potential. These restrictions are usually issued by local or county governments, as seen in Colfax County, which recently issued a burn ban placing several fire districts under restriction. They are temporary and remain in effect until weather conditions improve and fire danger decreases. Public notices, official county websites, and local fire agencies typically provide updates on current burn ban status, exemptions, and enforcement details.

Webinar: Community Response to Wildfire
March 11 | 11-12PM MDT
As part of the Fire Science You Can Use webinar series, Rocky Mountain Research Station is hosting a webinar on March 11 at 11AM MDT that will feature two presentations about community response to wildfire. The presentations will discuss wildfire governance and community adaptation in fire-prone landscapes in the West, as well social media case studies from two wildfire events.
As Southwest Wildfire Awareness Week (March 23–27) and National Wildfire Preparedness Day (May 2) approach, community leaders and fire practitioners are gearing up to host events and create meaningful opportunities to engage their communities. The Oregon State University Extension Fire Program has developed a helpful primer focused on engaging adult community members at the local level in wildfire preparedness efforts. The guide offers practical strategies for planning inclusive engagement activities, tailoring outreach to different adult learning styles, and incorporating trauma-informed approaches to better support the whole community.
For those organizing preparedness events this spring, this resource provides thoughtful, research-based guidance to strengthen outreach and impact!
