As of when I'm writing this post at 11:46 p.m. on Sunday night, over 1,200 residents have been evacuated and at last count, 3 homes have been completely destroyed. By the time you read this post, though I pray they won't be, I'm certain both those numbers will be significantly higher. Currently, the fire is 0% contained due to high winds / gusts that are making the fire's path unpredictable.
If you'd like more information regarding the Herriman Fire, which has also been called the Machine Gun Fire due to the cause of the fire (started at the machine gun range at Camp Williams), here are some links you can check out.
Wishing safety to all those affected.
