California Wildfires

Firefighters put out a hot spot from a wildfire Thursday, Oct. 12, 2017, near Calistoga, Calif. Communities in wildfire-prone Northern California have an array of emergency systems designed to alert residents of danger: text messages, phone calls, emails and tweets. But after days of raging blazes left at least 23 dead, authorities said those methods will be assessed after some residents complained those warnings never got through. (AP Photo/Jae C. Hong)
