1Opening

On the morning of August 8, 2023, a downed power line sparked a brush fire near Lahaina, Hawaii, on the island of Maui. Wind gusts exceeded 80 miles per hour — driven by Hurricane Dora passing south of the islands and a high-pressure system to the north. The morning fire was declared contained by 9:00 AM. Firefighters left the scene.

It reignited in the afternoon. By 2:52 PM, 911 calls were coming in again. The fire jumped Lahaina Bypass Road at 3:22 PM and was moving at catastrophic speed into a town of 12,700 residents — historic buildings, dry grass, wooden structures, all in the path of 80-mile-per-hour downslope winds. Within 15 minutes of entering town, fire had spread to the town center. Roads were blocked. Traffic gridlocked. People fled to the ocean.

3The Dispatch Picture

Hawaii has the world's largest integrated outdoor siren warning system — approximately 400 alarms statewide, with more than 80 on Maui alone. They are tested monthly. Residents know their sound. Not one was activated during the Lahaina fire. Officials later said they feared activating sirens — traditionally used for tsunamis — would cause residents to evacuate uphill toward the fire rather than away from it. Residents told investigators they had less than 10 minutes' warning before smoke and flames overtook them. Some had none.

At the dispatch level, all 21 cell towers serving West Maui went offline as power poles burned. 911 operators were monitoring five or six radio channels simultaneously with limited personnel. High winds made radio communication unreliable. There was no reliable line between Hawaiian Electric Company's control room, Maui Police Department dispatch, and firefighters on the ground — the critical question of whether downed power lines on evacuation routes were de-energized was asked and answered multiple times with conflicting information, keeping roads blocked during the window when evacuation was still possible.

Just after midnight on August 9, Maui County announced on social media that the 911 system in West Maui was down entirely and people should call the Lahaina Police Department directly.

"Nobody at the state and nobody at the county attempted to activate those sirens based on our records."— Adam Weintraub, Hawaii Emergency Management Agency spokesperson, CNN, August 2023

4Where Judgment Mattered

Alert systems without public education are half-systems. Lahaina residents knew the monthly siren test. They didn't have a shared mental model for "siren + wildfire." Activating the system might have caused harm. That's a systemic failure of preparedness communication that predates August 8, 2023 by years. If your jurisdiction's outdoor alert system has only one public meaning, that gap needs to be on your radar.

Two redundant systems failing at the same moment for opposite reasons is what total alert collapse looks like. Sirens were not activated. Cell alerts were issued just as the towers were failing. Both unavailable when needed most.

The framing of utility coordination questions matters. Maui PD asked about Lahainaluna Road. They needed information about Highway 30. The fix is not smarter people — it's better protocols that force the broader question: "what is the status of all lines in the evacuation corridor, and can you clear us to use these specific roads?"

Somebody needs to own the evacuation route picture. Police were blocking Highway 30. Dispatch was asking about a different road. Nobody had the job of mapping all blocked routes, status, and who was working to clear them. In a mass evacuation, that function needs to exist and be assigned.

Five to six channels means systematic information loss. Human beings can attend to one audio stream meaningfully at a time. In a mass casualty incident, low-urgency-sounding transmissions that turn out to be critical, requests during attention to a different channel, gradual escalation — all get missed. APCO/NENA standards recognize channel load as a direct factor in dispatcher error.

Channel assignment protocols for MCIs need to be defined before the MCI. Who owns which channel, with clear hand-off procedures. Supervisor monitoring during surge events. Mutual aid activation triggers before saturation, not after.

When the 911 system fails mid-incident, broadcast radio is the most resilient backup. Social media is nearly useless to people without power or cell service. AM/FM remains the most resilient mass communication medium in infrastructure failure scenarios. Door-to-door notification is a real option and sometimes the only option.

Amateur radio (HAM/ARES) networks exist for exactly this scenario. Most counties have an Amateur Radio Emergency Service group with trained operators who can establish communications when infrastructure is down. Do you know who your county ARES coordinator is?

"Contained" under extreme wind conditions is provisional. The morning Lahaina fire was legitimately contained as of 9:00 AM. Standard protocol said leave. Conditions — 80-mph winds, drought, NWS red flag warnings — should have maintained higher alertness regardless. Information that contradicts a closed incident is a flag, not a nuisance.

NWS red flag warnings are operationally relevant to dispatch. A red flag warning means extreme fire behavior is possible. In a fire-prone service area, that should change posture on any fire-adjacent calls for the duration of the warning.

5Discussion Questions

No right answers. Tap a question to expand the analysis. Use one or all — whatever fits your time.

1The siren decisionOfficials chose not to activate Maui's 80+ outdoor sirens because they feared residents would evacuate toward the fire. Does that reasoning hold up — and what does this decision tell you about the relationship between alert systems and public behavior?

The siren decision is contested. The official explanation — that sirens are associated with tsunamis and would prompt people to move uphill, toward the fire — has some basis in behavioral research on warning compliance. But it has also been sharply criticized, because the alternative was silence, and 102 people died with little or no warning.

The deeper issue is that this was a decision made under pressure, about a system that had only one default use case in public memory. If sirens only ever mean "move to high ground," then their activation during a downhill wildfire threat is genuinely ambiguous — not because sirens are a bad idea, but because nobody had built the message infrastructure to go with them.

This is a pre-incident planning failure, not a dispatch failure. The decision to activate or not activate sirens during a wildfire was made by emergency managers, not dispatchers. But dispatchers operate in the environment that decision creates. If your jurisdiction's outdoor alert system has only one public meaning, that gap needs to be on your radar.

Alert systems without public education are half-systems. Lahaina residents knew the monthly siren test. They didn't have a shared mental model for "siren + wildfire." The result was that activating the system might have caused harm. That's a systemic failure of preparedness communication that predates August 8, 2023 by years.

The question for your center: What does your outdoor alert system mean to residents in your area? Is there one meaning, or multiple? Do people know what to do when they hear it during a wildfire vs. a flood vs. a chemical release? If the answer is "I don't know," that's information worth surfacing.

Cell phone alerts were issued at 4:16 PM — just as the cell towers were failing. The two redundant systems — sirens and cell alerts — were both unavailable at the moment they were needed most, for opposite reasons. One was not activated. One couldn't get through. This is what total alert system collapse looks like.

2The power line coordination problemAt 4:11 PM, Maui PD dispatch called Hawaiian Electric to confirm power lines were de-energized — but only asked about Lahainaluna Road, not Highway 30, the primary evacuation route. Police were blocking Highway 30 because they believed it was unsafe. Nobody coordinated the two pieces of information. What failed here?

This is a textbook coordination gap: two agencies operating correctly within their own lanes, with no shared picture of the whole problem. Maui PD dispatch asked a specific, accurate question. Hawaiian Electric gave a specific, accurate answer. But the question was about the wrong road, and neither side realized it.

The failure was framing, not intent. Dispatch asked about one road. The information they needed was about another road. In a chaotic incident with overwhelmed personnel and failing communications, this kind of narrow framing is common and predictable. The fix is not smarter people — it's better protocols that force the broader question.

When you're coordinating with a utility during a wildfire MCI, the right question isn't "is this specific line de-energized?" It's "what is the status of all lines in the evacuation corridor, and can you clear us to use these specific roads?" That's a different question and requires a different answer — and it needs to be asked explicitly.

The second failure was that nobody owned the evacuation route picture. Police were blocking Highway 30. Dispatch was asking about a different road. Nobody had the job of mapping "here are all blocked routes, here is what we know about each one, here is who is working to clear them." In a mass evacuation, that function needs to exist and be assigned.

For your center: When you coordinate with a utility company during an emergency, do you have a protocol for what questions to ask? Do you know the name and direct number for the utility's emergency operations center? Have you ever run a tabletop that includes a utility coordination scenario?

3Monitoring 5–6 channels aloneDuring the peak of the Lahaina fire, single dispatch operators were monitoring five or six radio channels simultaneously. What does that actually mean for what gets missed — and what are the human limits that dispatch centers need to build systems around?

Five to six channels means five to six simultaneous information streams, each of which can carry a critical transmission at any moment. Human beings can attend to one audio stream meaningfully at a time. Everything else becomes background noise until a tone, a word, or volume change triggers attention. In a calm period, this is manageable. In a mass casualty incident, it means systematic information loss.

What gets missed: Low-urgency-sounding transmissions that turn out to be critical. Requests that come in while attention is on a different channel. Radio traffic that escalates gradually rather than with a sudden change. A unit reporting they're lost, or surrounded, or running out of water — on a channel nobody's actively monitoring at that second.

The research baseline: APCO and NENA standards recognize that radio channel monitoring load is a direct factor in dispatcher cognitive overload and error rates. Most centers have internal policies that try to limit single-operator channel loads during MCIs. Whether those policies are honored when staffing is thin is a different question.

What your center can build around this: Channel assignment protocols for MCIs — who owns which channel, with clear hand-off procedures. Supervisor monitoring during surge events. CAD flags that alert when a unit hasn't transmitted in a defined period. Mutual aid activation triggers before saturation, not after.

The honest conversation: If your center runs minimum staffing on a Tuesday night and a wildfire or major incident starts, how many channels will one dispatcher be monitoring? Is that number survivable? Has anyone done the math?

4When 911 itself goes downThe 911 system in West Maui went completely down after midnight. Maui County told people to call the Lahaina Police Department directly — on social media, in an area where most people had no power and no cell service. What do you do when your primary emergency communication system fails mid-incident?

This is the dispatch nightmare: the system you rely on to receive calls fails during the event. The Lahaina 911 outage is an extreme case, but partial system failures during major incidents are not rare. Every center needs to know the answer to this question before it needs to use it.

Know your PSAP's continuity of operations plan (COOP). What is the backup when your primary 911 system fails? Is there a secondary PSAP that can receive overflow? Is there a backup call center number that can be published? Who authorizes activating it, and how fast can that happen?

Know where public notification goes when cell and internet are down. Social media is nearly useless to people without power or cell service — exactly the people most affected by the event. Broadcast radio (AM/FM) remains the most resilient mass communication medium in infrastructure failure scenarios. Does your PSAP have a relationship with a local radio station that can push emergency messaging? Is that relationship tested?

Door-to-door notification is a real option and sometimes the only option. In Lahaina, residents who survived often got warning from neighbors, from seeing smoke, or from police driving through neighborhoods. When electronic systems fail, human-to-human notification becomes the alert system. This should be a planned function, not an improvised one.

Amateur radio (HAM) networks. Most counties have an Amateur Radio Emergency Service (ARES) group with trained operators who can establish communications when infrastructure is down. Do you know who your county ARES coordinator is?

5The "contained" callThe morning fire was declared "contained" at 9:00 AM. Crews left. It reignited under 80-mph winds in the afternoon. How do you handle a "contained" or "resolved" status when conditions on the ground are still extreme — and what does dispatch do with information that contradicts a closed incident?

The morning Lahaina fire was legitimately contained as of 9:00 AM. Firefighters followed standard protocol and left the scene. The weather conditions that caused it to reignite — 80-mph winds, extreme drought, National Weather Service red flag warnings — were all known. The question is not whether the "contained" call was wrong at 9:00 AM. It's whether conditions should have maintained a higher state of alertness than standard procedure allowed.

Dispatcher's role with a "resolved" incident during red flag conditions: You don't override fire command. But if conditions in your service area are at NWS red flag warning level, you should be in a heightened state of awareness on any fire calls, even ones that have been declared contained. That means closer attention to follow-up calls from the area, faster escalation of any reports of smoke or reignition, and awareness that "contained" under extreme wind conditions is provisional.

Information that contradicts a closed incident is a flag, not a nuisance. If the incident is closed and a caller reports smoke from the same area, that is not a false alarm to be dismissed — it's a datapoint that needs rapid escalation and verification. Your job is to get that information to someone who can act on it quickly, with enough urgency that it's treated as a potential reignition, not a stale call.

NWS red flag warnings are operationally relevant to dispatch. A red flag warning means extreme fire behavior is possible. In a fire-prone service area, that should change your posture on any fire-adjacent calls for the duration of the warning. Know what that means for your center — is there a protocol, or is it left to individual dispatcher judgment?

The Maui County hazard mitigation plan from 2020 identified Lahaina as lying within a high risk zone for wildfire. The National Interagency Fire Center's August 2023 seasonal outlook, issued August 1, forecast "above normal" fire potential for Hawaii's leeward sides for that month. Both documents existed and were available. The question of who reads them and how they inform operational posture is a pre-incident preparedness question — but dispatchers are part of that ecosystem.
