The emergency manager, and who owns the sirens
- View
What an emergency operations center is, how your report reaches it, and the answer to why the sirens did not sound.
In this lesson you will
- Define an emergency operations center and describe its activation levels.
- Describe the county emergency manager role in spotter programs.
- Explain the basics of the national incident management system as they affect a spotter.
- State who owns and activates outdoor warning sirens.
What module 1 already covered
Module 1 lesson 6 owns the dissemination chain: how a warning leaves the office and reaches people, through the wire services, satellite, weather radio and its county codes, broadcast alerting, and phone alerts through the federal gateway, including which warnings set off a phone and which do not. This lesson does not repeat it.
What module 1 did not cover is the other institution in the room. Between you and the public there is a county emergency manager who has their own building, their own communications and their own decisions to make, and who is frequently the person who trained you.
The emergency operations center
An EOC is a physical place where the people who run a county during an emergency sit together: emergency management, law enforcement, fire, public works, utilities, sometimes a broadcaster and sometimes an amateur radio operator. It is not a command post at the scene. It is where resources are coordinated and decisions that affect the whole jurisdiction get made.
| Activation level | Roughly what it means |
|---|---|
| Steady state, or monitoring | Normal. Somebody is watching the forecast; nobody has been called in |
| Partial activation | Specific functions staffed for a specific threat. A severe weather day looks like this |
| Full activation | Everybody in, around the clock. A landfalling hurricane or a major outbreak |
Names and numbering vary by jurisdiction, and some use numbered levels running the opposite way. The concept is universal: a dial from watching to everybody in the building.
In a great many counties the emergency manager is the local spotter program. They organize the training, they hold the roster, they run or sponsor the net, and they relay ground truth to the forecast office alongside their own operational traffic. Find out who yours is before the season. They are a shorter path to being useful than any app.
Incident management, briefly
Multi-agency emergencies in the United States run on a common framework, so that a fire department from one county can plug into an incident in another without a week of translation. A spotter does not need to be an expert in it and does benefit from three things.
- Common terminology. The reason lesson 4 insisted on plain language. Everything in the framework is built on strangers understanding each other on first contact.
- A clear chain. Somebody is in charge, it is knowable who, and information flows along it rather than around it. On a net, that person is net control.
- Where you fit, which is at the very beginning: you are an information source feeding the net or the emergency manager. You are not a responder and you do not self-deploy.
FEMA publishes free online independent-study courses, and two are the standard introduction: IS-100, an introduction to the incident command system, and IS-700, an introduction to the national incident management system. They take a couple of hours each, they are free, and they are what your emergency manager did. Neither is required to be a spotter.
How your report reaches the office through an EOC
Lesson 1 drew this as one of the two relayed paths. In practice the EOC has channels a member of the public does not, and that is the point of the route.
- The partner chat, which is core-partner only and is where an emergency manager can talk to a forecaster directly and quickly.
- Direct telephone lines, which are not the public spotter line and are not congested by it.
- A dedicated data feed of products, so the EOC sees warnings the moment they are issued rather than when an app refreshes.
- The amateur station, if one is staffed, which is often physically in the EOC.
It costs you one step and it puts your observation in front of both the people forecasting the storm and the people who will send somebody to look at the damage. On a bad night that second audience matters more.
The sirens
The question every spotter is eventually asked, usually angrily, and the answer is not the one people expect.
Outdoor warning sirens are owned, maintained and activated by local government: a city, a county, sometimes a fire district. The NWS issues the warning. What happens to the sirens afterwards is a local decision made against local policy. There is no national standard for when they sound, what the tones mean, or whether an all-clear is given, and neighboring counties genuinely do things differently.
Which produces a set of consequences worth being able to explain calmly to a neighbor.
- The forecast office is the wrong place to complain. They issued the warning; they do not control the siren.
- Policies differ by county, so "they sounded them over there" is not evidence that yours malfunctioned.
- They are outdoor warning devices. They are designed to alert people who are outside, and they were never intended to wake you up indoors. A weather radio is.
- An all-clear may not exist where you live. Many jurisdictions deliberately do not sound one.
This course quotes primary sources wherever it can. There are no quotation marks in this section, because although forecast offices say this plainly and one publishes a whole FAQ page on it, a verbatim sentence could not be extracted from the agency page to quote. The fact is not in dispute anywhere. The quotation is absent because the course does not put quotation marks around something it has not read.
Check yourself
A neighbor is furious that the sirens did not sound during last night tornado warning. What is the accurate response?
- Sirens are owned and activated by local government, not the NWS, and policies differ by county
- The NWS must have failed to activate them, and the forecast office should be contacted
- Sirens only sound for confirmed tornadoes, never for radar-indicated warnings
- The warning must not have been issued in time for the sirens to be triggered
Hint
Two different organizations are involved, and only one of them owns hardware on a pole.
Answer
Sirens are owned and activated by local government, not the NWS, and policies differ by county
The NWS issues the warning; a city or county owns and activates the sirens under its own policy, and there is no national standard. The third option is a real local policy in some places and not a general rule. The useful follow-up is to point the neighbor at a weather radio, since sirens are outdoor devices and were never meant to be heard indoors.
