https://en.wikipedia.org/wiki/2023_Hawaii_wildfires 2023 Hawaii wildfires In
early August 2023, a series of wildfires broke out in the U.S. state
of Hawaii, predominantly on the island of Maui.
The wind-driven fires prompted evacuations, caused widespread damage, killing
at least 115 people and leaving at least 110 others missing[7][9] in the town
of Lahaina, Hawaii.
The proliferation of the wildfires was attributed to dry, gusty conditions
created by a strong high-pressure area north
of Hawaii and Hurricane Dora to
the south.[10] An
emergency declaration was signed on August 8, authorizing several actions,
including activation of the Hawaii National
Guard, appropriate actions by the director of the Hawaii
Emergency Management Agency and the Administrator of
Emergency Management, and the expenditure of state general revenue funds for
relief of conditions created by the fires.[11] By August 9, the
state government of Hawaii issued a state of emergency for the entirety of
the state.[10] On August 10,
U.S. President Joe Biden issued
a federal major disaster declaration.[12] For
the Lahaina fire alone, the Pacific Disaster
Center (PDC) and the Federal
Emergency Management Agency (FEMA) estimated that over 2,200
buildings had been destroyed,[6][13][14] overwhelmingly
residential[15][16] and including
many historic landmarks in Lahaina.[17][18] The damage
caused by the fire has been estimated at nearly $6 billion.[6][2] Background Wildfire risk The
typical area burned by wildfires in Hawaii has
increased in recent decades, almost quadrupling. Experts have blamed the
increase on the spread of nonnative vegetation
and hotter, drier weather due to climate change.[19] During
the 2010s and early 2020s, Clay Trauernicht, a botanist and fire scientist at
the University of Hawaiʻi at Mānoa, and
several other experts warned that the decline of agriculture in Hawaii meant that
large areas of formerly productive land had been left unmanaged; nonnative
invasive species like guinea grass were
spreading rapidly and increasing the risk of large wildfires.[20][21][22][23][24] The state government failed to provide
incentives or impose mandates to keep land clear of grass.[23][24] The
state government also did not require all structure owners to maintain defensible space, a
standard rule in fire-prone states like California.[24][25] The
shrinking of the agricultural workforce reduced overall firefighting
capacity; those workers had traditionally suppressed fires on the land they
cared for, and were so effective that sometimes the counties called them for
help.[20] In
2022, Trauernicht suggested that Hawaii follow Europe's example by subsidizing
agriculture as a public good as a form of fire risk
reduction.[21] In
2023, UH Manoa biogeography professor Camilo Mora estimated the cost of land
restoration to mitigate wildfire risk at about $1 billion.[23] Despite
these calls to action, the Hawaii State Legislature had been
unable to make much progress; a 2022 bill to spend just $1.5 million on
additional fire risk reduction measures died in a legislative committee.[23] Around
the time the fires occurred, twenty percent of the county of Maui was
experiencing moderate drought (level 1 of 4), and sixteen percent of the
county was under severe drought conditions (level 2 of 4).[26] A
decrease in rainfall consistent with the predicted impacts of climate change
had also been recorded in the Hawaiian Islands, according to the U.S. National Climate Assessment.[27] In
the decades leading up to the fire, overdevelopment practices led to further
water management challenges that reduced the availability of water for
firefighting and exacerbated drought conditions.[28] In
June 2014, the Hawaii Wildfire Management Organization, a nonprofit
organization, prepared a Western Maui Community Wildfire Protection Plan
which warned that most of the Lahaina area was at extremely high risk for
burning.[29][30] In
Maui County's 2020 Hazard Mitigation Plan, the county identified Lahaina, the
most heavily impacted community in the August fires, as lying within a high
risk zone for wildfire.[31]: 481–522 In
its monthly seasonal outlook on August 1, 2023, the National Interagency Fire Center (NIFC)
forecast "above normal" potential for significant wildland fires
for Hawaii in August, concentrated on the islands' leeward sides.
In addition to noting plentiful vegetation growth from the previous wet
season and the expanding drought, the NIFC mentioned that "tropical cyclones can also bring windy
and dry conditions depending on how they approach the island chain and can
exacerbate fire growth potential".[32]: 1, 2, 7 The
vulnerability of the islands to deadly wildfires was gravely underestimated
in long term assessments. A year prior, the State of Hawaii Comprehensive
Emergency Management Plan Report had detailed wildfire risks as one of the
lowest threats for the state.[33] A
2021 Maui County assessment acknowledged the spike of wildfires in the state,
but described funds as "inadequate" and heavily criticized the
county fire department's strategic plan, claiming it said "nothing about
what can and should be done to prevent fires."[34] Weather factors In
early August 2023, a high-pressure system remained
north of the Hawaiian Islands. This formed strong surface pressure north of
the islands, and also sustained stabilization across the region, creating
warm and sunny conditions. Concurrently, Hurricane Dora began
to intensify to Category 4 strength, which may have helped to create a large
pressure difference between the high-pressure area and the low-pressure
cyclone. This pressure difference would have aided in already significant
trade winds moving southwest, and formed strong gradient winds over the islands.[35] (A similar
phenomenon occurred during the October
2017 Portugal wildfires during the passage of Hurricane
Ophelia.)[36] The exact
significance of Hurricane Dora and how it impacted the fires themselves
remains somewhat unclear. Meteorologists noted that the storm's center
remained more than 700 miles (1,100 km) from the islands and that it
remained relatively small in size; however it also remained "remarkably
potent for a long time", logging more hours as a Category 4 hurricane
than any other storm in the Pacific for over 50 years.[37] Philippe Papin,
a hurricane specialist with the National
Hurricane Center, argued that Hurricane Dora played only a minor
role in "enhancing low-level flow over Maui at fire initiation
time."[38] By
August 6, the National Weather
Service identified a region of very dry air arriving from the
East Pacific, greatly inhibiting the potential for rainfall.[39] A prominent
descending capping inversion forced
even more stabilization of
the atmosphere, which led to enhanced wind gusts and very dry
conditions between August 7 and 8.[39] As the day
progressed, deep layer ridging combined
with the existing pressure gradient created
very strong wind gusts and caused humidity levels to be well below
normal. The aforementioned cap was expected to only strengthen acceleration
of wind due to terrain features near the islands.[40] List of wildfires

Irma and Maria: Impact and Aftermath Puerto Rico
Situated between the Atlantic Ocean and the Caribbean Sea,
approximately 1,100 miles east-southeast of Miami, Florida, the archipelago
of Puerto Rico consists of a main island; two populated islands off its east
coast, Culebra and Vieques; and several smaller, uninhabited islands. Much of
the interior of the main island is mountainous, characterized by steep slopes
and narrow valleys and is relatively sparsely populated. The coasts, which
boast popular beaches and tourist attractions, are home to Puerto Rico’s
larger cities, including the capital of San Juan. Following the Spanish–American War, Puerto Rico became an
territory of the United States, and since passage of the Jones-Shafroth Act
in 1917, anyone born in Puerto Rico is a U.S. citizen with freedom of
movement to travel back and forth to the mainland. In 1950, Puerto Rico was
granted the right to organize a government with the passage of the Puerto
Rican Federal Relations Act. Two years later, the territory adopted a
constitution (Constitución del Estado Libre Asociado de Puerto Rico, 1952),
at which time it also became a U.S. commonwealth. The Storms In September 2017, Puerto Rico was struck by two
major hurricanes in quick succession. Hurricane Irma—a category 5 storm—passed close to the
main island of Puerto Rico on September 7, 2017, leading to widespread power
outages and water service interruptions for several days. Irma’s heavy rains
saturated the ground and its damaging winds weakened Puerto Rico’s
already-fragile physical infrastructure and natural systems. On September 10,
2017, President Donald Trump issued a major disaster declaration for Puerto
Rico (DR-4336)
and FEMA designated nine of Puerto Rico’s 78 municipalities as eligible for
FEMA’s Individual Assistance (IA), which provides relief for immediate needs
and housing restoration. Less than two weeks later, on September 20, Hurricane
Maria directly hit Puerto Rico as a category 4 hurricane with peak wind speeds
of up to 155 miles per hour, and was the most intense hurricane to make
landfall in Puerto Rico since 1928. So close on the heels of Irma, Maria
represented a near worst-case scenario for Puerto Rico. The storm’s path
moved directly across the main island, with the eye passing only 25 miles
from the capital of San Juan. Hurricane-force winds combined with Puerto
Rico’s mountainous terrain led to wind tunnels, increased rainfall, and flash
flooding. Many parts of Puerto Rico received at least 15 inches of rain in a
48-hour period. A second major disaster declaration was issued on September
20, 2017 (DR-4339), and FEMA extended eligibility for
both Public Assistance and IA to all 78 of Puerto Rico’s municipalities. The Immediate
Aftermath The effects of the 2017 hurricane season were
widespread and catastrophic. Damage to critical infrastructure resulted in
cascading failures of the lifeline systems of energy, transportation,
communications, water supply, and wastewater treatment and impeded response
operations. With these events occurring at the end of a very active hurricane
season, federal resources for disaster response were stretched, and aid from
other states was hampered by a lack of mutual aid compacts and geographical
distance. At the same time, Puerto Rico’s municipal governments, which are
typically the first responders during an emergency, were unprepared for a
disaster of this magnitude. Almost half of the municipalities’
emergency-response plans did not address how to protect children, seniors,
and people with disabilities. More than 95% of the Puerto Ricans lacked drinking water 28% of federally qualified health centers were damaged 90% of households applied
for assistance Almost 3,000 people lost their lives In the aftermath of the storms, some residents lacked
electricity, fresh food, and clean water for a prolonged period, and, with
roads impassable, many had limited access to medical care. And the effects
persisted in the days, weeks, and months that followed: government services
and private enterprise could not operate effectively, schools were closed,
landslide zones faced flooding hazards, and wastewater polluted marine
environments. Older adults, children, people with disabilities or chronic
illnesses, rural residents, and women all faced challenges to recovery. Puerto Rico is exposed to tropical cyclones
throughout the Atlantic hurricane season. In fact, hurricane is one of the
few words that survives from the original inhabitants of Puerto Rico, the
Taíno. Nevertheless, the one-two punch of Hurricanes Irma and Maria, combined
with the economic challenges and other stressors that Puerto Rico was facing
prior to these storms, led to an extended disaster response period. In some
cases, response activities were ongoing even as recovery plans were being
developed. Puerto Rico’s economic and disaster-recovery plan [PDF],
which was submitted to Congress on August 8, 2018, attempts to grapple with
these diverse challenges and position Puerto Rico for success in the future. |
