New real time mapping system used on Cave Fire

A new real time wildfire mapping system was used on the Cave Fire near Santa Barbara, California this week.

In September the Orange County Fire Authority began a 150-day pilot program to use and evaluate the Fire Integrated Real-Time Intelligence System (FIRIS). The program got off the ground thanks to funding secured in the 2019-2020 California state budget by Assemblywoman Cottie Petrie-Norris (D-Laguna Beach).

The system utilizes a fixed-wing aircraft equipped with infrared and radar sensors that can see through smoke. The plane provides real-time fire perimeter mapping and live high definition video to support supercomputer-based wildfire predictive spread modeling.

A supercomputer at the University of California San Diego runs WIFIRE spread projections based on fire perimeter data collected by the aircraft. The output estimates where the fire will be in the next six hours. The fire spread model adjusts for successful fire suppression actions by firefighters on the ground and in the air. This intel allows for more timely and accurate decision making for resource allocation and evacuations.

If I am correctly interpreting the WIFIRE product at the top of this article the system predicted that the Cave Fire would grow from 4,994 to 8,880 acres over a 90-minute period beginning at 10:56 a.m. on November 26, 2019. Spot fires were predicted more than a mile ahead. However, decreasing winds that day slowed the spread. A weather station in San Marcos Pass about three miles northwest of the fire recorded sustained wind speeds from 1 to 5 mph between 10 a.m. and 5 p.m. Rain beginning at 2 a.m. November 27 stopped  the spread at 4,330 acres.

The video below is “B-Roll”, that is, unedited footage of the FIRIS system. The first 6.5 minutes are simply images of aircraft, but after that you will be able to look over the shoulder of the imagery technician as he observes infrared imagery of a fire, manually interprets the heat signatures, then traces the fire perimeter on the screen. That perimeter could then be electronically sent to the super computer in San Diego County which would run a fire spread model to predict what the fire will do in the next six hours.

Our attempts to obtain more information about FIRIS from personnel on the Cave Fire that used the system were not successful.

Accuracy and Critique

Critique vs accuracy venn diagram

When a wildland fire incident has a controversial outcome it will often be pointed out by those who are knowledgeable on the subject, or by someone who is directly or indirectly affected.

I understand how venting can be cathartic. As long as it is done in private, no problem. If it is done in public there can be cascading repercussions, and therefore more responsibility. At worst, it can be self-serving, cruel, damaging, and counterproductive. But if everything said is completely accurate, and the result can benefit mankind, then the greater good might be served in many situations. At Wildfire Today, I know that sunlight can be the best disinfectant. Helping shine a little light on lessons learned by firefighters through information about reports being released or critique from various sources, might reduce the chances of someone else learning a lesson the hard way — with unpleasant consequences.

Years ago in a comment section on Wildfire Today someone made statements about another person. It was slanderous, not true, and damaged the reputation of a very honorable and skilled professional. Since then I have strived harder to have factual information on the web site. There are times when that objective is not met, but it does not stop me from trying.

Even the best intentioned formal investigations of incidents may occasionally miss the mark of being accurate. Other times the report an investigation team releases might purposefully deceive, or lie by omission. I certainly do not have all the answers, not by a long shot. In cases like these, and others, attention is needed by the hive mind of the wildland fire community.

Critique not meshing with accuracy can keep me up at night.

This is why you don’t want to be under a retardant drop

If that video does not convince you — last year a firefighter from Utah who was working on a fire in California was killed when a retardant drop uprooted an 87-foot tall tree that fell on him.

More details possibly emerge about air tanker’s hazardous exit out of drop area

BAe-146 air tanker hazardous retardant drop near miss
Screenshot from the video below of BAe-146 air tanker.

We posted a video on August 14 of a BAe-146 air tanker dropping retardant on a fire. While exiting the area the aircraft flew closely over a ridge stirring up dust on the ground. It generated many comments, with one person writing “it doesn’t appear to be a problem” while others considered it a good cautionary learning opportunity.

Yesterday one of our readers sent us information about a Safecom that may or may not be related to this incident. The report was filed August 1, 2019 by the crew of a BAe-146 about an incident that occurred July 1, 2019.

Here is the complete narrative:

While conducting retardant operations I descended below a ridge crossing altitude. This was NOT on purpose. I tunnel visioned the drop, and continued down. This was a little fill in spot and I was really focused on finishing the line. As I stated, this was NOT on purpose. We{crew} debriefed and talked about what happened, and of course, how to prevent this type of screw up. Thanks

The “Corrective Action” was presumably written later by someone in aviation management:

Crew will review SOP`s, CRM, etc. RASM: Glad to see the crew realized and admitted what occurred. Hope to see others follow suit as narratives like this remind us all to be diligent.

Cutting it close on a fire retardant drop

Thanks and a tip of the hat go out to Ryan. Typos or errors, report them HERE.

North Carolina firefighters suppress fire in deep organic soils

From the North Carolina Forest Service:


Mop-up efforts on the Squires Timber Fire in Pender County concluded this week and it’s now in monitor status. NCFS rangers are keeping an eye on this to make sure it stays out. About three acres of the wildfire were in a Carolina bay with heavy organic soils which made for challenging control as the fire burned as much as two feet deep. The 8-acre wildfire began April 29 but flared back up after long, hot, and dry days. The initial cause was an escaped debris burn.
