 Well, Weber Fire District responded to a pile of hay bales on fire that led to three structures being threatened yesterday. David Reed with the Weber Fire District said they got the call at around 240 yesterday afternoon, and when crews arrived, they found a pile of hay bales on fire. He said the cause is still under investigation, but they believe the bales were cut and had piled up, but while they were still wet, which could have caused heat to spread through the bales and cause it to combust.
