These factors are making it hard to combat the deadly Maui wildfires

Oh my gosh. Look at the harbor. The view from above is of shock and heartbreak. Oh my God. We were not prepared for what we saw. It looked like an area that had been bombed in the war. Wildfires rampaging across the island of Maui. Our entire street was burned to the ground, decimating homes and businesses. Local people have lost everything. They've lost their house, they've lost their animals and it's devastating is on fire. The historic town of Lahaina, *** popular tourist in economic hub on the island's west side, particularly affected with hundreds of structures impacted. It happened so fast. People stuck in traffic trying to get out and they, they're slang on, on both sides of the road like something out of *** horror movie. Most of the fires on Maui fueled in part by violent winds caused by hurricane Dora churning more than 800 miles away. Those winds now subsiding as the storm pushes away. The primary focus is to save lives and to prevent human suffering and mitigate great property loss. State Department crews assisting in efforts to restore communication across the islands and distribute water with military helicopters, aiding in extinguishing the fires. Two ch 47 supporting Maui County, they flew 13 hours did 58 drops and about 150,000 gallons of water to assist with suppression of the fire recovery will be *** long road ahead. According to Hawaii's Lieutenant Governor Sylvia Luke, the damage to the infrastructure. It's not just buildings. I mean, these were small businesses that invested in Maui. These were local residents and we need to figure out *** way to help *** lot of people in the next several years.

MAUI, Hawaii —

The wind-whipped fires in Maui spread swiftly and created a deadly tinderbox, overwhelming residents and local officials in one of the nation’s deadliest wildfires.

“It’s very strange to hear about severe wildfires in Hawaii �� a wet, tropical island �� but strange events are becoming more common with climate change,�� Jennifer Marlon, a research scientist and lecturer at the Yale School of the Environment, told CNN.

Fueled by a combination of strong winds and dry conditions �� and complicated by the island’s geography �� the fires have killed at least 36 people.

“For those of us who’ve been working on this problem, it just makes us feel sick,�� said Clay Trauernicht, an assistant specialist who studies tropical fire at the University of Hawaii at Manoa.

Maui’s wildfire appears to be one of the deadliest in modern US history. The fire already ranks as the second deadliest in the past 100 years, trailing California’s Camp fire, which killed 85 people in November 2018, according to

Trauernicht said it was by far the deadliest wildfire in Hawaii’s history.

These are some factors making it difficult to combat the fires that have plunged a state known for its stunning natural beauty into an unprecedented crisis:

Drought contributes to fire spread

Drought worsened in Hawaii over the past week, leading to fire spread, according to the released Thursday. Severe level drought conditions in Maui County ticked up to 16% from 5% last week, while statewide moderate drought levels jumped to 14% from 6%.

Dried-out land and vegetation can provide fuel for wildfires, which then can swiftly turn deadly if strong winds help fan the flames toward communities.

“It’s more a fuels problem than a climate problem �� which means that it’s a problem we can tackle,�� Trauernicht said in a phone interview.

“There are tangible actions that we could be taking that would reduce the risk of something like this happening in the future,�� he added, referring to measures such as the creation of fuelbreaks to reduce fire-prone vegetation and support for agricultural land use.

“It’s a priority when the fires are burning. But at that point, it’s too late.��

While scientists try to fully understand how the climate crisis will affect Hawaii, they have said drought will get worse as global temperatures rise: Warmer temperatures increase the amount of water the atmosphere can absorb �� which then dries out the landscape.

Drought conditions are becoming more extreme and common in Hawaii and other Pacific Islands, according to the Fourth U.S. National Climate Assessment, released in 2018. Rainfall has generally been decreasing in Hawaii over time, with the number of consecutive dry days increasing, scientists noted in the report.

And the climate crisis has caused droughts that previously may have occurred only once every decade to now happen 70% more frequently, global scientists reported in 2021.

“But this is what climate change is doing �� it’s super-charging extreme weather. This is yet another example of what human-caused climate change increasingly looks like.��

Hurricane-related winds fuel fire weather conditions

Hurricane Dora, a fast-moving and powerful Category 4 hurricane with sustained winds of 140 mph, isn’t helping matters.

As the storm roared south of Hawaii, a strong high-pressure system stayed in place to the north, with the two forces combining to produce “very strong and damaging winds,�� according to the National Weather Service.

“These strong winds coupled with low humidity levels are producing dangerous fire weather conditions�� through Wednesday afternoon, the weather service said.

The high winds, ongoing drought conditions and dry relative humidity are “ingredients to spark those fires and to fan the flames,�� CNN meteorologist Derek Van Dam said.

“The problem is that this wind �� similar to, let’s say, Santa Ana winds in Southern California �� is that it dries out and it warms up as it (travels down) the mountains, and it creates these very dry, timber-like conditions,�� he said.

Hurricane Lane in 2018 was also associated with large fires on Maui and Oahu, noted Abby Frazier, a climatologist and geographer at Clark University in Massachusetts.

“While we tend to see wetter conditions during El Nino summers (which builds up fire fuels), Hawaii should expect drought conditions likely this winter, which will dry out the fuels and usually leads to an earlier start to our fire season for next year.��

How the land is used has changed

Nonnative species now cover nearly a quarter of Hawaii’s total land area, and invasive grasses and shrubs become highly flammable in the dry season, Trauernicht said.

Hawaii also has lost large plantations and ranches, with fire-prone grasses overtaking fallow lands, he said.

“When plantations were active, firefighters would show up on scene �� people would be there opening the gates, all the roads were maintained, there was water infrastructure and equipment. And they would have support from the people working on these plantations,�� Trauernicht said.

Geography and limited resources stymie firefighting

The geography of Hawaii �� an island chain in the Pacific �� and limited firefighting resources also complicate efforts.

Personnel at the state Division of Forestry and Wildlife are primarily natural resource managers, foresters, biologists and technicians �� not full-time wildland firefighters, according to the

“West Maui is kind of a perfect example �� one highway through the whole place,�� Trauernicht told CNN. “Our resources are limited to what’s on island. The resources �� are going to be spread thin.��

Fewer than 300 firefighting personnel responded to the state’s second-largest fire, on the Big Island in 2021, Trauernicht said.
