Tropical Storm Lala Dumps Snow on Mauna Kea's 14,000-Foot Summit

Q: Does the rare summer snow on Mauna Kea distract from the catastrophic flooding and infrastructure collapse below?

Yes — it can, if coverage treats the snow as the main story rather than a meteorological side note. The snowfall on Mauna Kea is visually striking and unusual in the context of an August tropical system, but it is not the storm’s central impact. Snow on Mauna Kea itself is not rare because the summit is nearly 14,000 feet high and often falls below freezing. What made this event notable was the timing and the storm setup: heavy tropical moisture, freezing temperatures aloft, and extreme winds over 100 mph. By contrast, the damage below was far more severe and consequential. Lala brought catastrophic flooding, landslides, road and bridge failures, major airport and harbor disruptions, and widespread blackouts affecting roughly 200,000 customers at peak. Officials reported at least 100 homes damaged or destroyed, search-and-rescue operations in flood-hit communities, and restoration in some rural parts of Hawaiʻi Island could take weeks or months. Local reporting described highway collapse, homes swept from foundations, and entire communities cut off. So the snow is newsworthy as an illustration of how extreme the storm was across Hawaii’s vertical climate zones, but it should not dominate the narrative. In responsible coverage, it belongs as a secondary detail that helps explain the storm’s atmospheric structure, while the headline reality remains the flooding, infrastructure collapse, displacement, outages, and public safety crisis affecting residents.

Q: Why did an August tropical storm trigger blizzard conditions on a Hawaiian volcano while sea levels sweltered?

It happened because Tropical Storm Lala supplied abundant moisture and extreme winds to Mauna Kea’s summit, where the air was cold enough for that moisture to freeze into snow despite hot conditions at the coast. The key difference was altitude. Mauna Kea rises to nearly 13,800 to 14,000 feet, and temperatures fall rapidly with height. Meteorologists cited a balloon sounding showing air cooling by about 5.5 degrees Celsius per kilometer. With sea-level temperatures in the upper 70s Fahrenheit, that drop was enough to bring summit temperatures to near or below freezing. Lala then added the other ingredients for blizzard conditions: deep tropical moisture, heavy precipitation and powerful wind. Rain falling through the much colder air at the summit turned to snow, while gusts topping 100 mph created whiteout-like, dangerous conditions on the mountain. In other words, the storm was tropical at low elevations but winterlike at the top of Hawaii’s highest volcano. Snow on Mauna Kea itself is not rare because of its elevation, and winter storm warnings are sometimes issued there. What made this event unusual was the timing and setup: an August tropical cyclone producing snow and blizzard conditions on a Hawaiian summit while beaches below remained warm and humid. As Lala weakened and moved away, the snowfall was expected to ease.

Snow fell on Mauna Kea's summit as Tropical Storm Lala pushed moisture over the Big Island, creating wintry conditions atop Hawaii's highest peak.
Nearly 14,000 feet of elevation dropped temperatures to near or below freezing, allowing the storm's heavy precipitation to turn to snow instead of rain.
More than 100 mph wind gusts and thick snow made summit conditions hazardous even without torrential rainfall at the observatory area.
Feet of rain and damaging winds were still driving dangerous flooding elsewhere in Hawaii, though forecasters expect Mauna Kea snowfall to ease as Lala weakens.
