Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

Glenn’s Tuesday comments:  I’m here at home in upper Kula, Maui

535am Monday morning, with cloudy skies and rain here at my place, with the low temperature 54.5 degrees, along with the relative humidity 82%.

840am, here in upper Kula the rain keeps coming down, and over on the windward sides it’s even wetter! We are having beautiful rainbows this morning too!

 

>>> Highest Temperature Monday, March 23, 2026 – 102 degrees near Tecopa, CA
>>> Lowest Temperature Tuesday, March 24, 2026 – minus 3 degrees near Millinocket, ME

 

Hawaii’s Broad Brush Weather Overview…as of 343am Tuesday:  After a prolonged stretch of impactful kona weather and heavy rainfall across the state, a gradual return to a more typical northeast trade wind pattern is expected by mid-week. A lingering moisture axis over the eastern end of the state, combined with an upper trough, will support periods of locally heavy showers and storms today, mainly over Maui and the Big Island. Thereafter, a drier and more stable trade wind pattern is expected from late week through the weekend into early next week.

Weather Details for the islands…as of 343am Tuesday:  Latest satellite imagery shows a narrow and persistent convergent cloud band over and upstream of the Haleakala windward slopes of Maui, that continues to fuel heavy showers this morning (over 4 inches of rain in the past few hours as of 3am). Elsewhere, mostly dry northeast trade wind conditions prevail across the island chain. Dew points have dropped into the lower 60’s across the western end of the state, resulting in noticeably cooler and more comfortable conditions compared to recent days.

The past several days have been exceptionally wet across portions of the state, particularly from Oahu through the Big Island. Peak rainfall totals over the past 5-days have generally ranged from 15 to 25 inches in some areas, with a preliminary statewide peak of 25.73 inches observed at Kaala on Oahu, most of which fell Thursday night into Friday. This recent period of heavy rainfall has led to saturated soils and elevated stream flows, leaving areas very sensitive to additional rainfall.

Looking ahead through mid-week, a lingering axis of moisture over the eastern end of the state, combined with cold temperatures aloft associated with a departing but still influential upper trough, will maintain the potential for locally heavy showers and thunderstorms today, especially across Maui and the Big Island. Given the saturated ground conditions, even modest additional rainfall could lead to renewed runoff and localized flooding concerns. As a result, a Flood Watch has been extended through this afternoon for Maui and the Big Island.

Elsewhere, more stable conditions are expected as trade winds strengthen and drier air filters into the region. By Wednesday and beyond, the state should transition into a more typical trade wind pattern featuring passing windward showers and generally drier leeward conditions. This pattern is expected to persist through the remainder of the week and into the weekend, consistent with broader guidance indicating decreasing moisture and a return to climatological conditions.

Hawaii’s Marine Environment…as of 343am Tuesday: Upper level energy diving down into a trough lingering near Big Island will keep the chance of eastern water showers and isolated thunderstorms alive. High pressure building far north of the area will result in strengthened northeasterly winds across the local nearshore waters. A Small Craft Advisory is in effect for all coastal waters due to these increasing northeasterlies and elevated seas. Winds will be strongest through Wednesday, but should ease Thursday. Moderate trades will close out the week.

A fading north-northwest swell will be overlapped by a reinforcing pulse of medium period north northeast swell. This swell will peak and then decline Wednesday. Another small, medium period west-northwest swell will arrive Thursday, peak Friday, then decline during the weekend. Aside from areas along east shores exposed to the northerly swell, short period energy from rebuilding trades will increase to near seasonal averages tonight and Wednesday and then hold into the weekend. A small south-southwest swell will decline and then fade Wednesday. A short-lived pulse of small south-southeast swell will be possible Wednesday through Friday, and a small south-southwest swell could arrive Friday into the weekend.

Interesting:  Climate Change May Complicate Avalanche Risk Across the Pacific Northwest

This winter was one of the warmest on record across the West; as a result, many snowy, alpine areas have seen bouts of winter rainfall where there would ordinarily only be snow. These unusual weather patterns have contributed to an abysmal ski season, but they can also set the stage for dangerous avalanches. At temperatures close to freezing, precipitation can fall as rain but freeze when it hits the snow, forming an icy crust. Snow that accumulates on top of that crust is unstable and prone to abrupt slides, causing an avalanche that can close down a major highway in moments, endanger backcountry skiers and more.

Avalanche experts in Western Washington know how to manage the risks associated with rain-on-snow events, but many of their counterparts in colder regions like Eastern Washington, Idaho and Montana are less familiar with these dynamics. New research from the University of Washington shows that as winters in these regions warm, their snowpacks may come to resemble those of maritime areas, with more rain-on-snow events, icy crusts and complex avalanche forecasting.

The findings were published in ARC Geophysical Research.
