How unusual was the 2023 hurricane season for Hawaii?
Хей, і цьлора, арсеню та сенс фридай. The Hawaiian islands tend to be insulated from the worst effects from hurricanes. But this summer told a different story. In mid-August, Hurricane Lala struck the big island, damaging homes and roads, creating flooding and power outages. Then a few weeks later, Hurricane Lowell hit the islands of Nihihau and Kauai, leaving more destruction in its wake. So what do scientists make of this dramatic storm season for the Hawaiian Islands? Joining me now is Dr. Haunani Kane, an assistant professor at the University of Hawaii at Manoa, where she studies how climate change impacts islands, reefs, and island people. Welcome to Science Friday. Aloha Flora Mahalo for having me here today.
Thank you so much for being here. How anomalous is this hurricane season for Hawaii?
This hurricane season has been wild. The fact that within a month we had two back to back hurricanes, that is definitely something that I have not experienced in my lifetime. Mm.
I mean do hurricanes usually make landfall in Hawaii?
It's rare. It's rare for hurricanes to make landfall in Hawaii.
Why are warmer El Niño waters fueling stronger Hawaiian hurricanes?
Um a lot of times as you have mentioned, we're buffered from the majority of the storms. due to both our isolated location But also the fact that a lot of these hurricanes they enter cooler waters before they come close to Hawaii. So With this year with El Nino, with the prolonged warming of our oceans, the fact that our ocean is actually warmer and that there are numerous hurricanes that are coming straight for Hawaii. It's been It's been frankly, it's been a bit scary for um for a lot of the people that live here in Hawaii.
Mm, is that how it feels for you?
Yeah, I think so. I live in Hilo, um On the Big Island or Hawaii Island, we're used to getting a lot of rain. We're used to getting wind. Um but this much rain like upwards of ten, fifteen inches over the course of a day or two. That It's been a lot.
So just to unpack it a little bit, we have an El Nino year and you mentioned that the waters are getting warmer and is the problem that then the hurricane doesn't lose power? Like if it's not bumping into colder waters, it sort of stays powerful.
How do stronger storms affect Hawaii’s coral reefs and shorelines?
Yeah, so when you look at um typically what happens during El Nino and also what is forecasted with climate change, you see that within El Nino year the waters are warmer, so that's more fuel for the hurricane. The warmer water season is prolonged with El Nino through the fall. And then the fact with climate change. It's projected that This warmer water. And these warmer air temperatures will also steer the hurricanes further towards the west and towards the north. So it'll allow those tracks to come closer to Hawaii as well.
I mean, I think on the news we've seen damage to houses and infrastructure. How are these storms impacting natural features like reefs and shorelines?
Yeah, so we're still we're still learning. We're still studying, we're still trying to figure out exactly how these storms have directly impacted our reefs. We've seen photos from reefs along the south shore of Maui that have been damaged. Um we've seen beaches that are covered in coral rubber and um This reminds me of um a hurricane that came to Hawaii in twenty eighteen. Um, Hurricane Walaka, and it was the first time in recorded history that this hurricane, a category three hurricane, made direct landfall um on one of the northern atolls in Papahna Mokwakia National Marine Sanctuary. And what we saw there is these large, beautiful, pristine reefs with large plated corals be completely Completely ripped off of the reef platform and closed.
Instead you s you saw after the hurricane large fields of rubble and sand.
What can past hurricane events, like Hurricane Walaka, teach us about reef damage and recovery?
What we saw also was that the Entire islands were completely enclosed. moved or swept off um into the lagoon. And over the past eight years we've been studying the recovery of these reefs. So And trying to understand um as a reef recovers, what are the first things that pop up? what are the first types of corals, what are the first types of algae and then how that then translates into the recovery of the islands and, you know, seeing those cascading effects throughout the ecosystem.
