The weather is being blamed for the deaths of the 19 firefighters who lost their lives battling the Yarnell Hill Fire .
In major wildfires, crews may call in a meteorologist who specializes in how weather can affect wildfires.
They're called incident meteorologists, and they help inform fire crews of changing conditions and can help make predictions at the scene to keep those crews safe.
But in the Yarnell Hill Fire, the ABC15 Investigators have learned that no incident meteorologist was requested until Monday morning.
The only request for weather information was for a "spot forecast" which is described as a detailed weather forecast for a specific location.
That request came hours before the 19 firefighters found themselves surrounded by a wall of fire.
At the time of the deaths, the Yarnell Hill Fire was classified as a Level 3 fire which is right in the middle of a possible five categories that measure severity.
But, given the dramatic and sudden shifts in weather during monsoon season, the question now is whether an incident meteorologist should have been at the scene when the firefighters were fighting the fire.
An investigative team is looking into what happened. Stay with ABC15 for updates.
