Raging wildfires continued to blaze across the western U.S. on Wednesday, menacing homes and forcing evacuations.
In the Pacific Northwest, the flames have threatened American Indian tribal lands already affected by a historic regional drought.
RISING SMOKE: AFTER 10.3M ACRES BURNED IN US LAST YEAR, WEST'S 2021 FIRE SEASON OUTLOOK UNCERTAIN
Nearly 70 active fires have burned more than a million acres – a worrying tally for this early in the 2021 fire season.
Additionally, the National Interagency Fire Center said Wednesday that almost 34,000 fires had burned more than 2 million acres across the country since January.
Heat waves that have swept the West have not helped aid the efforts of the 16,600-plus firefighters and support personnel in attacking the fires.
While the ongoing heat is expected to abate across the Southwest, the National Weather Service (NWS) said Wednesday that "noteworthy positive anomalies" would still exist over inland portions of the Pacific Northwest and Great Basin through Thursday and elevated-to-critical fire weather would persist there.
Oregon's week-old Bootleg Fire – which has destroyed at least 20 homes in lands near the California border – has doubled in size every day, spreading to an area larger than New York City.
"As you go out there today — adjust your reality," incident commander Al Lawson told firefighters on Tuesday. "We have not seen a fire move like this, in these conditions, this early in the year. Expect the fire to do things that you have not seen before."
To the south, California has made progress on the Beckwourth Complex, reporting that the lightning-ignited fires were almost 50% contained.
SOUTHWEST UNDER FLASH FLOOD WARNINGS AS MIDWEST FACES LARGE HAIL AND TORNADOES
The Golden State's power grid operator asked residents for voluntary power conservation Monday after that fire disrupted three transmission lines that provide electricity to the state.
Several fires also burned in north-central Washington state, prompting an evacuation order for the small town of Nespelem and about 60 lightning strikes were reported nearby on Monday.
Airport officials that provide aerial relief are facing jet fuel shortages – specifically at tanker bases in Oregon, Arizona and Utah.
The demand for jet fuel plummeted amid the COVID-19 pandemic and has yet to bounce back even as more Americans get vaccinated and state and local economies reopen.
It is not yet clear if jet fuel supplies and delivery systems could be strengthened in time to help, and many smaller airports rely on jet fuel delivery by truck.
Govs. Kate Brown of Oregon and Brad Little of Idaho have already issued emergency orders in response to these fires – fearing the worst as critical reservoirs and water sources remain scarily dry.
According to the U.S. Drought Monitor, more than 93% of the West is impacted by moderate to exceptional drought.

Scientists say that worsened and extreme conditions are a result of a combination of human-caused climate change and unusually random, short-term and natural weather patterns, predicting that the West will only become hotter and more arid in the future.
However, while this warming was contributed to the West's "megadrought," special studies are needed to determine its impact on a single extreme weather event.
