Forecasters are warning Americans to brace for another extreme heat wave this week, as 107 large wildfires burn across nearly 2.3 million acres of the U.S. West.

Driving the news: "Widespread air quality alerts and scattered Red Flag Warnings stretch from the Northwest and Northern Rockies to the High Plains, as well as throughout parts of central California," the National Weather Service said Sunday.

"It's going to be a real oppressive week with dangerous heat and hot conditions across much of the U.S. Excessive heat watches are up across much of the Pacific Northwest for mid to late week, including in the Portland and Seattle metro areas. Meanwhile, heat advisories are in effect for a good part of the south-central U.S. and parts of western New York state."
— NWS

State of play: The massive wildfires were burning across 15 states on Sunday —with weather conditions already dangerous in several places, according to the National Interagency Fire Center.

  • The Dixie Fire, California's second-biggest wildfire in the state's history, is the largest blaze now burning in the U.S. It has destroyed 627 buildings, damaged 42 other structures and razed 489,287 acres as of Sunday night.
  • "Near critical conditions with wind gusts up to 45 mph were reported over north central Montana, and up to 30 mph in eastern Oregon," the NIFC noted in its statement.
  • "These winds caused active fire behavior on the Whitmore, Green Ridge, Black Butte, Thorne Creek, and Woods Creek fires. Extensive smoke continues to blanket California, although many wildfires were active in the late afternoon."

By the numbers: Per the NIFC on Sunday, 25 large fires were burning in Montana, 20 in Idaho, 16 in Oregon, 13 in Washington state, 11 in California, 10 in Alaska and four in Wyoming.

  • Colorado, Utah, Nevada, Arizona, Minnesota, South Dakota, Nebraska and New Mexico had each reported one large fire burning.

What to watch: "The fire outlook continues to reflect warmer and drier conditions leading to the high potential for severe wildfire activity throughout the western United States through the rest of summer and into the fall," per the NIFC.

  • "Widespread high temperatures observed across areas in the West and with periods of lightning activity continue to exacerbate the wildfire situation."

The big picture: The past few months have already seen an unprecedented, deadly heat wave in the Pacific Northwest, with wildfires raging well ahead of peak fire season.

Colorado predicted to have a warmer, drier winter

The return of La Niña for the second straight year means winter in Colorado will bring warmer temperatures and less precipitation than normal, according to a new forecast by the National Oceanic and Atmospheric Administration.

Why it matters: Dry conditions have fueled some of Colorado's most devastating wildfires, including last year's East Troublesome blaze, which raged for more than a month and destroyed nearly 194,000 acres.

A major storm system was pummeling Northern California and parts of the Pacific Northwest with heavy rains overnight.

The big picture: The "atmospheric river" storms, associated with a record-strong "bomb cyclone" offshore from the Pacific Northwest, have brought flooding and mudslides to parts of California that were razed by recent wildfires and in severe drought. It's also caused widespread power outages in California and Washington state.
