Hawaii to see ‘potentially life-threatening weather’ with massive rain, flooding


The National Weather Service warns of a “high-impact and potentially life-threatening weather pattern” in Hawaii this week, with torrential rainfall, flash flooding, strong winds, severe thunderstorms and mountain snow.

Through Saturday, “we could easily see over 20 inches in the harder-hit areas, but that’s just a ballpark estimate,” said Laura Farris, a meteorologist at the weather service office in Hawaii.

Greater totals are possible atop the state’s volcanoes, which can measure feet of rain from the biggest storms.

The cause is a strong low-pressure system that will bring two rounds of stormy weather to the state Tuesday through Saturday. These systems are locally referred to as ‘Kona lows,’ and are responsible for Hawaii’s most extreme weather during winter months.

“The high-end potential of this Kona storm is significantly outside the realm of ‘normal’ wet season weather,” the weather service said.

Heavy rain will begin over Kauai on Tuesday morning before reaching Oahu on Tuesday night, prompting the weather service to issue a flood watch for those islands, which is in effect through Saturday afternoon.

A lull in storminess Thursday won’t last long, as “an even stronger disturbance is expected Friday into Saturday with major flooding and damaging winds,” the weather service said. That storm is likely to prompt additional flood watches and warnings for Maui and other Hawaiian islands. About 10 inches of rain is predicted in Honolulu, with 30-plus inches of rain possible atop the state’s volcanoes, through Saturday.

Severe thunderstorms could generate hail and damaging winds, with isolated tornadoes even possible Friday and Saturday. Thunderstorm chances are highest for Kauai and Oahu initially, but the second disturbance over the weekend will raise odds for hail, wind and tornadoes across all islands. Significant snow accumulations are forecast for the summits of the Big Islands.

Hawaii is no stranger to heavy rain, as Mount Waialeale, on Kauai, is one of the wettest spots on Earth and averages nearly 40 feet of rain each year, according to NASA. But rainfall rates are expected to approach 2 to 3 inches per hour within the heaviest bands, too much for even tropical islands to handle without flooding.

This Kona low will have an abundance of moisture to work with. The low’s counterclockwise motion, in tandem with an anomalous clockwise-spinning high-pressure system to the east, will work to draw abundant moisture toward Hawaii from the south. It’s the same area of high pressure responsible for the spring heat wave that’s forecast to grip the Western U.S.

The moisture transport won’t stop upon reaching the island state. It will continue northeastward toward the Pacific Northwest, where a strong Pineapple Express may raise flood danger early next week.

The Rally Point: Navy Leaders on the importance of Navy Week in Hawaii


HONOLULU (HawaiiNewsNow) – For the first time, Navy Week is being held in Hawaii. From March 9 – 15, Sailors (majority based on Oahu) and also abroad Hawaii namesake vessels will be here to learn more about the culture, the people, and the communities in which the are stationed at and ultimately, serve through service projects to education by visiting local schools to share more about the Navy resources and satellites, buoys and water currents, and speaking engagements with senior ranking Navy officers to include Rear Admiral Ryan Mahelona who is the third Native Hawaiian to reach this rank, a local boy, born and raised in Kaneohe who graduated from Kamehameha Schools – Kapalama Campus.

Commander Daniel Jones, commanding officer of the USS Hawaii and Commander David Taweel will join Jonathan on Wednesday, March 11, 2026 to talk about Navy Week in Hawaii.

The Rally Point is a new show that airs every other Wednesday at 12:30 p.m. on all of HNN’s platforms.

Host Jonathan Masaki, a retired Army lieutenant colonel, will focus on engaging conversations with military service members and defense department civilians and contractors on military-related issues that impact Hawaii and our community.

Towering lava fountains of Hawaii’s Kilauea volcano trigger park and highway closures

Towering lava fountains of Hawaii’s Kilauea volcano trigger park and highway closures


HONOLULU — The latest lava fountaining episode of an erupting Hawaii volcano reached 1,000 feet high Tuesday, prompting temporary closures at a national park and part of an important highway because of falling glassy volcanic fragments, including ash.

Kilauea, on Hawaii’s Big Island, has been dazzling residents and visitors for more than year with an on-and-off eruption that periodically sends fountains of lava soaring into the sky.

The fountaining that began Tuesday morning marked the eruption’s 43rd episode since it began in December 2024. A livestream showed two fountains of bright-red lava and smoke. It’s unclear how long the fountaining will last. Some episodes have lasted a few days and others a few hours.

Like other times, the molten rock was confined within Kilauea’s summit crater inside Hawaii Volcanoes National Park and hasn’t threatened homes or buildings.

But the lava fountains were creating trouble for neighboring communities and a highway where the volcanic fragments and ash, known as tephra, was falling. The tephra prompted temporary closures at the national park around the summit and a partial closure of Highway 11, an important route around the island, on either side of the park.

Hawaii County officials also opened a shelter at a district gymnasium for residents and tourists impacted by the road closure or falling tephra. There were no people using the shelter soon after it opened, said Tom Callis, a county spokesperson.

The National Weather Service issued an ashfall warning.

Volcanic tephra can irritate eyes, skin and the respiratory system, according to county officials. Tephra also can clog and cause other problems with water catchment collection systems, which are common in some parts of the Big Island, officials said.

Ash fell so heavily during a previous fountaining episode that some communities needed help from county civil defense workers to clean up ash that coated their homes, Callis said.

Episode 43: Volcano Warning issued for Kilauea due to falling ash and tephra


HAWAII VOLCANOES NATIONAL PARK (HawaiiNewsNow) – The U.S. Geological Survey has upgraded the Kilauea alert level to a Volcano Warning due to fallout of the latest high-fountaining at Halemaumau crater.

The National Weather Service also issued an ashfall warning until 5 p.m. Tuesday for Hawaii Volcanoes National Park and communities to the northeast, including Volcano, Glenwood and Mountain View.

Episode 43 began Tuesday at 9:17 a.m. HST with more than a quarter-inch of accumulated tephra, including ash and other volcanic particles, reported within the first 90 minutes.

The USGS said fallout up to the size of footballs was reported at lookouts within Hawaii Volcanoes National Park, creating hazardous ground conditions.

The National Weather Service said the plume from this episode rose to 25,000 feet. Surface level winds are reported coming from a southerly direction, which means that volcanic gas emissions and fallout may be distributed to areas northeast of the summit.

Communities adjacent and downwind of the eruption need to take necessary precautions for elevated tephra fallout and volcanic gases.

Closures in effect, shelter open

Highway 11 is closed on either side of Hawaiʻi Volcanoes National Park (HVNP) at mile markers 24 and 40. HVNP is also closed.

The County of Hawaiʻi has opened a shelter at Kaʻū District Gym, 96-1219 Kamani St., Pāhala, for residents and visitors impacted by the road closure or falling tephra.

Safety information

Volcanic tephra, including ash, can irritate eyes, skin, and the respiratory system. Take necessary precautions to limit exposure.

  • If you have a respiratory condition, avoid contact with ash. Stay indoors until it is safe to go outside.
  • Close doors and windows, where possible.
  • Wear masks, gloves and eye protection when in contact with ash.
  • Do not drive in heavy ashfall.

Tephra also can clog and cause other problems with water catchment collection systems.

  • Temporarily disconnect the gutters feeding into the tank. Do not reconnect the system until the volcanic hazards (i.e. ash, laze, Pele’s hair in the air) have passed and the ash and debris are washed off the roof, out of the gutters and the tank.

Use caution when clearing rooftops of ash.

Road closures may occur without warning.
