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 Sunday comments:  I’m here at home in upper Kula, Maui

It’s cloudy early this morning, with off and on gusty winds, and a low temperature of 55.5 degrees at my place, and the relative humidity is 75%.

835am, it’s windy here at my place but it’s not crazy yet, and the power is still on thank goodness. The truth is that I expect the power or internet connectivity to go off at some point today. The rain isn’t falling very much, with just off and on generally light showers, nothing crazy in that department yet either.

845am, just in the last 10 minutes we had quite the pile driver gust come through, and I’m afraid we ain’t seen nothing yet!

1045am, the wind has stopped although we’re having a light shower here in Kula

115pm, it’s lightly raining although the winds are calm, now that the winds have taken on a more northeast to easterly direction, putting Kula in the leeward side of the Haleakala Crater.

>>> All State offices and all public schools close Monday, February 9th due to severe weather

>>> Highest Temperature Saturday, February 7, 2026 – 88 near Indio, CA
>>> Lowest Temperature Sunday, February 8, 2026 – minus 34 at Watertown, NY

 

I suggest that we all, at least those of us who live in Hawaii, keep our devices charged up as long as possible, in case the power goes out as the winds increase going forward

 

Hawaii’s Broad Brush Weather Overview…as of 933am: The cold front near Maui has dissipated into a surface trough this morning. Windy trade winds will continue to strengthen over the state as a high pressure system builds in from the north. A deepening upper low will linger west to southwest of the Hawaiian Islands through Monday, before drifting westward away from the islands by Tuesday. High pressure building in from the north will produce stronger trade winds today above warning levels in some areas.

Unstable conditions from the nearby upper low, deep unstable moisture and strong winds flowing over mountain ranges will keep periods of heavy rain, thunderstorms, and flooding threats in the forecast through Monday. Heavy shower activity and flood threats will diminish from Tuesday onward as the upper low departs the pattern. Wind speeds will decrease slightly from Tuesday into Wednesday, likely falling just below advisory thresholds for the second half of the week.

Short Term Update:  The system is going pretty much according to forecast so far. Locations on the Big Island (Honokaa and Spencer) have reported over 10 inches of rain in the past 24 hours. There are multiple reports of trees down and power outages on all islands. A wind gust of 55 mph was reported at the Lanai airport a short time ago, and many other gusts greater than 40 mph have been reported. Look for the winds to continue to increase in speed through tonight and maintain higher levels well into Monday. Flood advisories are currently in effect for windward Molokai and windward Big Island.

 

Flood Threat Outlook: 

What
> Heavy rain leading to flash flooding
Where
> Entire state, particularly windward areas
When
> Sunday into Monday
Impacts
> Flooding of roads, streams, and poorly draining areas

 

Damaging Wind Threat: 

What
> Strong, sustained trade winds 30+ mph
> Gusts 60+ mph possible
Where
> Entire state, particularly over and downslope of terrain, through valleys, and other local acceleration areas.
When
> Late Sunday through Monday
Impacts
> Potential for power outages, downed tree limbs
>Weaker trees may be uprooted
> Driving may be difficult in high profile vehicles

 

Hawaii’s Weather Details…as of 409am: Periods of heavy rain continue to threaten the Hawaiian Islands through Monday. Overnight rainfall amounts in rain favored areas ranged from 1 to 4 inches across the state. Terrain anchored storms along windward slopes (north and east slopes) of each island represent the highest flood threat due to the strong trade winds driving heavy rain up against the windward mountain ranges of each island. Last night these terrain anchoring storms formed rapidly along the windward slopes of the Kohala Mountains and the Hamakua Coast on the Big Island where the highest rainfall totals were observed.

An area from eastern Waimea town to Waipio Valley and to Honokaa reported the highest rainfall with over 7 inches of rain falling over a three hour time period. A Flood Advisory was upgraded to a Flash Flood Warning for this Big Island event, and several land slides were reported in the area by the Hilo Police Department. A Flood Watch also remains in effect statewide through Monday.

Snow levels will remain around the 11,000 foot level through this event, and a Winter Storm Warning continues for snow and blowing snow over the highest summits of Mauna Kea and Mauna Loa on the Big Island through Monday.

Strong damaging winds are an additional threat lasting at least through Monday, and possibly lasting into Tuesday. A Wind Advisory will upgrade to a High Wind Warning this morning, as windy trade winds continue to strengthen throughout the day. The primary mechanism for these damaging winds will develop as strong trade winds may create breaking mountain waves that will pull down stronger winds aloft and cause damaging wind gusts to around 60 mph along southern and western slopes of island mountain ranges.

Additionally, as convective heavy showers and thunderstorms develop they will reach up into the higher levels of the atmosphere and pull down these stronger winds aloft producing wind gusts to around 60 mph at the surface level over the next 48 hours. These winds will gradually decrease from Tuesday into Wednesday, however breezy to locally windy easterly trade winds will linger through the end of the week.

The weather pattern begins to shift Monday night into Tuesday as the upper low lingering just southwest of the Hawaiian Islands begins to drift farther westward away from the state. Models remain in good agreement that this pattern shift will herald stabilizing trends, effectively eliminating the threats of heavy rain and thunderstorms over the islands from Tuesday onward. However, continued strong easterly trade winds through the week will continue to produce periods of wet trade winds over the islands, just at a lower intensity each day due to increasing subsidence aloft and a lowering of the temperature inversion height.

Hawaii’s Marine Environment:  A trough currently over central waters, a developing low pressure several hundred miles southwest of the islands and strong high pressure building north of the front, is driving these strong to gale force northeast trade winds along and north of the feature. A Small Craft Advisory (SCA) remains in effect for all Hawaiian waters due to a combination of winds and large. A Gale Warning will be in effect starting this morning through Monday afternoon for all coastal water zones for winds and seas. In addition, expect heavy showers and isolated thunderstorms through Monday. Winds are expected to ease some on Tuesday, but trade winds will remain in the strong range with some locally near gales over the windier waters and channels through the forecast period.

The current moderate west-northwest swell (295-310 degrees) will continue to gradually decline through Monday. The High Surf Advisory (HSA) has been cancelled for all north and west facing zones. Small to moderate north-northwest to northwest swells will prevail through the remainder of the week.

Large and very rough seas will begin to develop as trade winds strengthen. East shore surf should rise above the HSA threshold tonight, with the potential for surf to reach the High Surf Warning (HSW) level Monday and Tuesday on Kauai and Oahu. Large east shore surf will slowly decline Tuesday into Wednesday, but will still remain somewhat elevated through the remainder of the week. Surf along south facing shores will remain small with some small background south-southwest energy expected throughout the first half of the week. Select southern exposures exposed to the wind swell will likely see some larger waves as well.

Interesting:  As the Arctic Gets Louder, Narwhals Are Going Quiet

In a warming Arctic, noise from growing shipping traffic is interfering with the ability of narwhals to hunt and communicate.

For most of their evolutionary history, narwhals have relied more on sound than sight to survive in the Arctic’s dark icy waters.

The speckled toothed whales — sometimes referred to as “unicorns of the sea” for the long, spiral tusks that protrude from the heads of males — navigate, hunt, and communicate using echolocation. By emitting a series of calls, whistles, and high frequency clicks — as many as a thousand per second — and listening for the echoes that bounce back, they are able to locate prey hundreds to thousands of feet deep and detect narrow cracks in sea ice where they can surface to breathe.

But as global temperatures continue to rise, the acoustic world narwhals depend on is rapidly shifting throughout their range, from northeastern Canada and Greenland to Norway’s Svalbard archipelago and Arctic waters in Russia. It’s getting louder.
