California & Oregon wildfires 2020
WHEN?
• The fire season, which traditionally peaks in late summer and into the fall, has been expanding — sometimes starting as early as the spring, and lasting into late fall. Wildfires in the Sierra Nevada region and the Pacific Northwest have also gotten larger and more frequent in recent years.
• With more than a month of fire weather ahead for large parts of the West Coast, the 2020 fire season has already taken a disastrous toll.
WHY?
• Wind-fanned wildfires spread further across California, Oregon and Washington, destroying hundreds of homes and killing at least seven people.
Strong, dry, offshore winds that are causing extreme fire behaviour, which can produce mushroom cloud-like plumes of smoke that reach 40,000 feet in height and fire vortexes.
WHO?
• Millions up and down the coast have spent weeks living under thick clouds of smoke and ash.
• Wildfire smoke has also been linked to longer-term consequences, like lower birth weight for babies and impaired lung function in adults.
WHERE?
:
Oregon, Washington, and California are enduring the largest fires, but wildfires are also burning in Utah, Nevada, Arizona, Wyoming, Idaho and Montana.
Whole towns in California, as well as Oregon and Washington, have been razed.
Thousands of people in the Western states have had to evacuate their homes. The death toll from the fires is expected to rise over the next few days.
HOW?
• Many fires were started because of human causes (pyrotechnic devices, car emissions, powerlines, including most of the fires in California.
• Lightning strikes in August sparked a number of the blazes, while unusually strong winds, warm temperatures and dry conditions have fuelled additional fires.
WHAT?
Wildfires are burning millions of acres, devastating towns and blanketing communities in thick smoke.
At least 24 people have died in California alone, and officials worry that the toll will continue to rise in coming weeks as more places become accessible to rescuers and investigators.
Nasa captured the high-altitude smoke and associated aerosols - particles in the air - as they travelled east to New York City and Washington DC in the middle of last week.
The fires are record breaking.
