Hurricane Lala dumped sufficient rain on Hawaii to fill 1.9 million Olympic swimming swimming pools

HONOLULU (HawaiiNewsNow) – Researchers said Lala dumped an extraordinary volume of water across the state — equal to 1.9 million Olympic-size swimming swimming pools — when it handed south of Hawaiʻi as a hurricane and tropical storm.

Data compiled by the University of Hawaiʻi’s Hawaiʻi Mesonet and the Hawaii Climate Data Portal revealed that Hawaiʻi Island acquired 66% of the storm’s complete precipitation, absorbing 833 million gallons of water.

They launched an interactive website documenting the weather impacts of Hurricane Lala.

Record-breaking rainfall depth

During the height of the storm on Saturday evening, the Kaiholena climate station — positioned upslope of Naʻalehu — recorded a outstanding 4.4 inches of rain in a single hour. Devastating flooding hit the city of Naʻalehu round that very same time.

In some areas of Hawaiʻi Island and Maui, storm totals exceeded 40 inches.

“You put even a few inches of rain across the big area, that is a lot of water,” mentioned Thomas Giambelluca, director of the Hawaii Mesonet. “And we had over 40 inches of rain during the whole storm in some areas. So just think about that, the entire land area in a certain part of the island with a rainfall accumulation that is 3 1/2 feet deep. That’s a lot of water.”

In addition to the historic downpours, the climate stations recorded wind gusts reaching as much as 80 mph.

Historical storm comparisons

While Lala’s totals have been excessive, Giambelluca famous that the state has skilled comparable or higher deluges lately. In March, the spring Kona lows introduced rainfall quantities that exceeded Lala.

In April 2018, Waipā on Kauaʻi recorded over 49 inches of rain in 24 hours, setting the present United States report. Later that 12 months, in August 2018, Hurricane Lane produced as much as 100 inches of rain over 4 days on Hawaiʻi Island.

“It fortunately did not make landfall and it weakened, but it produced some spectacular rainfall totals, especially on… Hawaii Island, where we had maybe as much as 100 inches in four days in some places,” Giambelluca mentioned.

Researchers mentioned the info highlights how excessive climate patterns can concurrently set off a number of crises. During Hurricane Lane, emergency responders on Maui needed to cut up assets between large flooding on the east aspect of the island and wildfires that broke out in Lahaina.

“This was not the one we all think about now from August 2023. It was five years before that, but there were wildfires around Hana,” Giambelluca mentioned. “It was particularly bad because the emergency responders were rushing to the floods and the fires broke out and they weren’t available to help deal with that.”

El Niño patterns and climate monitoring

Researchers analyzed the storm utilizing the Hawaiʻi Mesonet, a statewide community of greater than 80 climate stations.

Giambelluca emphasised that the real-time knowledge offered by the community is important not only for emergency responders, but additionally for researchers, water useful resource managers, farmers, and ranchers.

Giambelluca added that the lively tropical storm season is typical for the beginning of a robust El Niño 12 months, which usually brings a moist dry season.

“If it continues to hold the pattern of the past, we’ll have a very dry wet season coming up starting around December,” he mentioned. “This doesn’t always happen, but it generally does happen in the very strong El Niños.”
