Siren Tone Change
As of May, 2019 Campbell County has changed the alert tone used for it's monthly tests and Tornado Warnings. The warning is now a solid, continuous tone lasting 45 seconds for the monthly test, and 3 minutes for actual Tornado Warnings. Both the test and warnings are preceded and followed by a 30 second voice message.
Campbell County tests the sirens on the Second Tuesday of each month.
- 8:30 a.m. in Wright
- 10:30 a.m. in Gillette
Help Us Test Our Sirens!
Go to the online reporting form and tell us what you heard (or didn't hear!)
Some Things to Know:
- If you hear them AND it's not time for a test...SEEK SHELTER! We only set them off if the area they serve is being threatened!
- We don’t sound an all clear afterwards
- There are NO designated public shelters in Campbell County
Remember, you're not always in the same place all the time so you need to plan in advance where you would take shelter if the sirens sound.
Make certain those you leave your children with have a plan!
Don't have time to make it to a shelter? FEMA has information about how you can build your own tornado shelter
Campbell County's SkyWarn® Program
Campbell County Emergency Management has a cadre of trained SkyWarn® spotters who provide CCEMA real-time severe weather information.
The program operates with the support of the Rapid City NWS Office and helps document real-time weather events.
This is NOT a Storm Chaser program, and members must agree they will not "storm chase" as a SkyWarn® member.
Those signing up to be part of the SkyWarn® program must fill out an application form, attend one of the annual Severe Summer Weather Classes conducted each Spring by the Weather Service, completing three (3) on-line SkyWarn training classes and three (3) on-line FEMA classes on the Incident Command System.
During weather events, the SkyWarn® Spotters provide the Campbell County Emergency Operations Center specific storm information by way of radio, telephone or the internet and in turn, the EOC provides the information to the Rapid City Weather Forecast Office as well using the information when making advisory and warning decisions.
Our Lightning Prediction System in Gillette and Wright
Installed in the fall of 2018, our ThorGuard Lightning “Prediction” system lets all of us know in advance that conditions are building towards a lightning strike
The system includes hyperstatic sensors at six primary sites. They monitor electrical charges in the atmosphere within 15 miles of the sensor
It’s related warning equipment provides warning that the system is predicting a lightning strike will occur within the next 10-15 minutes within 2.5 miles of the sensor
The warning triggers a 15 second horn, and a strobe light that goes off until the all clear, when the horn will go off three times, 5 seconds each
Each of these sensor sites have a Warning Horn and flashing Strobe Light, and each of them also has 1 to 3 remote warning horn/strobe light sites that are slaved off of the nearest sensor site.
Using your smart phone, tablet or computer, go to:
There are five detector sites in Gillette, one in Wright.
- Thunder Basin High School
- Campbell County High School
- Bicentennial Park
- Bell Nob Golf Course
- Wright High School
When you open up one of the sites, there is a lot of information displayed:
The little red bar in the center of the black line displays the type of electrical charge being sensed at that site.
- If the bar moves to the left, it’s mostly negative charges.
+ If to the right, it’s mostly positive charges.
LHL—Lightning Hazard Level
The percentage chance of lightning / amount of energy within 15 miles of this sensor
The percentage chance of lightning / amount of energy change within 2.5 miles of this sensor
The time since the last discharge/lightning strike. It will count down from 10 minutes, and at zero, an ALL Clear will be signaled (three 5 second blasts of the warning horn)
FCC-Field Collapse Count
How many lightning strikes (field discharges) within 15 miles since the last time the system went into alert status (the point when it last predicted a strike within 2.5 miles within the next 10-15 minutes)
