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.

"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."

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.

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.
