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

It’s cloudy and raining 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 84%.

1030am, the rains have stopped and the wind is calm here in upper Kula, although showers, some heavy, continue to fall elsewhere.

1214pm, there are some hints that we could see another round of rain during this coming Valentine’s weekend…stay tuned.

238pm, it’s cloudy and cool and feels like it could start showering at any time…here in upper Kula

>>> All State offices and all public schools are closed today, February 9th due to severe weather

>>> Highest Temperature Monday, February 9, 2026 – 90 near Martinez Lake, AZ
>>> Lowest Temperature Monday, February 9, 2026 – minus 27 at Watertown, NY

 

I suggest that we all, at least those of us who live in Hawaii, keep our devices charged up 

 

Hawaii’s Broad Brush Weather Overview…as of 903am Monday: Wet and windy weather will continue across the islands today, with conditions gradually improving this afternoon into tonight as winds ease up some, and rainfall coverage and intensity diminishes. A more typical trade wind pattern will then follow Tuesday through late this week, although it will remain rather breezy.

Hawaii’s Weather Details…as of 851am Monday:  Ongoing event nearing an end as the gradient begins to slowly weaken today. Estimated rainfall totals so far around 3-6″ over windward Oahu, up to 15″ on the northern slopes of Molokai, just shy of 10″ over windward Maui, and around a foot along the North Kohala and Hamakua coasts of the Big Island. Kauai comes in last with a pocket estimated around 5″ atop Mount Waialeale. Light to moderate stratiform rain will blanket the eastern 2/3 of the state today, while weakly convergent trade wind showers become focused increasingly westward, eventually bringing an enhancement to shower activity over Oahu by mid to late afternoon.

This weak convergence exists along the lead edge of mid-level dry air punching into the region from the east. This dry air will scour out mid-level moisture and bring increasing stability tonight into Tuesday. The parent low to the west of the islands slides to the southwest and brings an effective end to the event. The Flood Watch remains in effect until 6pm with no expectations that it will extend into tonight.

Current observations indicate the downslope machine is still going this morning, with gusts to 50 mph over southern Molokai and 59 mph at the Olowalu anemometer on Maui. Gusts are similarly in the 45-55 mph range in the Kohala District of the Big Island. Daytime heating will allow gusts to creep upwards in magnitude today, but the 70+mph readings of yesterday become less likely with each passing hour. Subtle increase in stability as early as this evening may keep gusts elevated into the evening.

The High Wind Warning remains in effect until 6pm and will likely be transitioned to a Wind Advisory this evening if not sooner. The Winter Storm Warning for the Big Island summits is also likely to expire on schedule this evening, as developing subsidenc, impinging mid-level dry air, and gradual loss of deep moisture will spell an end to meaningful snowfall, though a few flakes may continue to fall through the first half of the night.

Hawaii’s Marine Environment:  A low pressure system southwest of the Hawaiian Islands slowly drifts westward, as a strong high north of the state slowly drifts eastward. Wind speeds will weaken slightly through the day, as both large scale pressure systems begin to move away from the island chain. Strong to gale force winds remain in the forecast for both coastal and offshore waters, and a Gale Warning remains in effect through the afternoon hours for all Hawaiian waters. Fresh to locally strong easterly trade winds will linger in the forecast for all coastal waters with slight downward trends each day to Small Craft Advisory levels Tuesday into Thursday.

These strong to gale force trade winds will bring large and very rough surf along east facing shores lasting through tonight. A High Surf Warning remains in effect for exposed east facing shores through tonight. Surf heights along east facing shores will decline to advisory levels by Tuesday morning, then decline below advisory thresholds, yet remain rough from Tuesday night onward as trade winds ease across the region.

Small to moderate northwest swells will pass through the islands into the first half of next week. These smaller swells will keep surf heights on the smaller side. Looking into the extended forecast from the middle to the end of next week, we see a similar swell picture with no larger northwesterly swells for the foreseeable future.

Surf along south facing shores will remain small with some small background south swell energy expected over the next few days. Select southern exposures exposed to the wind swell will likely see some larger waves as well.

Interesting:  Hot Takes: How the Science of Saltwater-Tolerating Plants Could Protect Coastlines

Rising sea levels along coastlines not only threaten populations, but also pose a danger to agricultural crops, which may be damaged by surging amounts of saltwater. Researchers have, in response, sought to improve salt-tolerance in plants.

“This work reveals that just a few simple cell traits are critical to tolerating the extreme conditions experienced by some of the most distinctive and resilient plants in the world,” says Adam Roddy, an assistant professor in NYU’s Department of Environmental Studies.

Roddy is an author on a new study that focuses on mangrove trees—plants that grow along tropical and subtropical coastal areas where saltwater is abundant. The results showed that, compared to their inland relatives, mangroves have unusually small cells and thicker cell walls, which together provide the greater mechanical strength needed to tolerate saltwater while also preventing wilting.
