On Friday, September 26, 2025, what started as a normal day quickly turned into coordinated chaos thanks to a solid emergency plan.

Pinal County and the surrounding Phoenix metro area experienced a severe monsoon system characterized by heavy rainfall, flash flooding, and significantly reduced visibility while driving. The downpour severely impacted road safety.

What did we do?

Florence Unified’s Storm Response

For us here at Florence Unified School District, it meant delaying student dismissal due to high winds, flying debris, and trees, and driving visibility reduced to less than 2 miles at times.

Drivers were directed to stage at their respective schools' loading zones and wait for direction on loading students. Once students were cleared, we brought the buses to the front of campus, near the building, and loaded them one at a time. More important than ever for us was to ensure each student scanned their bus card so parents could track their trip home.

Prior to loading and departure at impacted sites, families were informed of anticipated delays in arrival home and directed to meet their students at bus stops. We would not let drivers drop students off and force them to walk any distance during the storm.  

In my district, on a sunny day, drivers are reminded that safety comes before schedule, no matter what. On this day, it was paramount, as routes ended up delayed, in some areas more than 1.5 hours.

Our dispatchers were handling a higher-than-normal call volume and talking drivers through detours and delays. Multiple communication channels were used to ensure that anyone who needed one-on-one support for longer than usual would not interrupt regular radio traffic.

GPS technology allowed us to watch buses progress during the storm.  

As conditions worsened, some drivers were forced to stop the bus and wait it out. Families were informed and kept in close communication. In other cases, the normal roadways we traveled were blocked by trees, debris, or flash flooding, requiring patience and skill to navigate alternate routes.

The storm brought flash flood warnings for Pinal and Maricopa counties, with reports of life-threatening flooding on highways, streets, and underpasses. Driving conditions were hazardous due to heavy rain, with officials warning against driving through flooded roads.

This, along with a storm the previous day, brought the region's highest single-day rainfall total in seven years.

As students were safely delivered to their stops, drivers checked in by radio and were either directed to return to base or dispatched to another school or area where help was needed.

What Training Teaches Us

We spend time in driver training discussing the what-ifs around situations just like this. Unpacking scenarios during tabletop exercises makes it so that when something like this does come up, it’s not unexpected, and we have worked through it together. Weather events, building evacuations, reunification, weapons on board, heat advisories, and medical emergencies are all on our list of things we prepare for.   

One of the most important things I believe others forget is that driving a bus is so much more than driving a bus. It requires practice, preparedness, and patience under pressure (and all that with up to 70 students behind you). If we practice, we know what to do when something happens.

I couldn't be prouder of my team, as on that day, despite the variables, 2,700 students were returned home safely. While our buildings and some vehicles were damaged from flying objects and hail, 81 vehicles and skilled staff navigated the conditions without incident.

This doesn’t happen by accident. It’s the result of preparation, documentation, communication, and practice.

After-Action Reviews

We also can’t forget the importance of debriefing after the fact. Anytime an extreme event occurs, it’s critical to have an after-action discussion sooner than later to hear what people were seeing, feeling, or missing, so we can do better next time.

That happened on Tuesday, Sept. 30, 2025, when we unpacked what happened and what required improvement. 

Radio communication was spotty due to the weather, various outages, and cell tower issues. 

The takeaway: A short FAQ for certain scenarios in each bus folder would have helped drivers know what to do if radio communication could not be obtained. This was a great reminder to make sure the team has confidence in what they have learned when there isn't immediate reassurance. 

In transportation, we must build teams that we trust in all circumstances. We do the best with what we have and get better each time. As always, nothing matters more than keeping students safe.
