#Hawaii's #KonaStorm triggers #flooding, 100-mph #winds and summit snow

An emergency declaration was issued as a prolonged #kona storm is bringing dangerous flooding, waterspouts, high winds over 100 mph and 1-2 feet of snow to the summits.

By Emilee Speck, Mar 11, 2026

Excerpt: "Storms are producing intense downpours capable of triggering localized flooding, especially in upslope areas. Heavier rainfall is expected over #Kauai and #Oahu and continuing into the weekend.

" 'This deluge of heavy rain will persist for most of the Hawaiian Islands on Saturday, exacerbating any ongoing localized flooding,' Glenny said.

"As more rain falls, life-threatening flash flooding, mudslides and other debris flows are possible."

Evacuation warning issued after possible Wahiawā Dam failure alert on Oʻahu, Hawaiʻi

A potential failure of Wahiawā Dam on Oʻahu, Hawaiʻi, triggered an evacuation warning at 18:55 LT on March 13, 2026, for downstream communities, including Haleʻiwa and Waialua. Authorities said conditions existed that could lead to dam failure capable of causing catastrophic flooding, prompting residents to prepare for possible evacuation. #evacuation #damfailure #Hawaii #HI

How the Edenville Dam Failed

Back in May 2020, the Edenville Dam in Michigan failed dramatically, releasing flood waters that destroyed a downstream dam and caused millions of dollars of damage. In this Practical Engineering video, Grady deconstructs the accident, based on an interim report from the forensic team charged with investigating the failure. Along the way, he explains common causes of dam failures, what made the Edenville failure unusual, and how engineers build modern earthen dams to avoid this older design’s flaws.

The Taum Sauk Dam Failure and Its Legacy

Managing an electrical grid is all about balancing the electricity that plants can supply with the instantaneous demands of consumers. If there’s more power available than people need, it needs to get stored somehow. And for decades, the best way to store that excess supply has been in hydroelectric reservoirs like at the Taum Sauk Dam. These facilities pump water to a reservoir at a higher elevation when there’s extra electrical power available, and, when more power is needed, release that water to run through hydroturbines.

But storing water atop a mountain comes with unusual challenges for dam, and the 2005 failure of the Taum Sauk Dam facility highlights some important lessons for engineers. As Grady lays out in this Practical Engineering video, there was no single mistake that led directly to the dam’s failure. Instead, post-collapse investigations found a series of seemingly minor issues that, together, led to catastrophe. It’s well worth watching, especially for engineers; we could all use an occasional reminder that a “quick stopgap measure” isn’t enough. (Video and image credit: Practical Engineering)
