Fires burning across West as heat waves affect millions around the country

Fires are continuing to spark in the West as a heat wave blankets millions of residents.

Fires are continuing to spark in the West as a heat wave blankets millions of residents. Heat alerts are currently active across seven states in the West as the heat wave continues into Sunday. Temperatures in the triple digits are expected in California, Arizona, Oregon and Idaho. Temperatures are set to break records in cities like Flagstaff, Arizona; Salt Lake City, Utah; Bakersfield and Fresno, California; and Billings, Montana. Extreme drought and dry conditions are persisting in the West as another heat waves looms, creating matchbox conditions for any spark to ignite into a fast-moving blaze. In California and Nevada, temperatures in the 90s and 100s -- along with single digit humidity values -- will be conducive to rapid spread again on Sunday.
