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

Hawaii’s Broad Brush Weather Overview…as of 3pm Monday: Unsettled 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.


High Surf Warning until 6am Tuesday for east facing shores of all
Hawaiian Islands.

Small Craft Advisory until 6pm Tuesday for Kauai Northwest
Waters-Kauai Windward Waters-Kauai Leeward Waters-Kauai Channel-
Oahu Windward Waters-Oahu Leeward Waters-Kaiwi Channel-Maui
County Windward Waters-Maui County Leeward Waters-Big Island
Windward Waters.

Gale Warning until 6pm Tuesday for Maalaea Bay-Pailolo Channel-Alenuihaha
Channel-Big Island Leeward Waters-Big Island Southeast Waters.
 

Hawaii’s Weather Details…as of 3pm Monday:  Push of mid-level dry air has brought an end to winter precipitation on the summits of the Big Island, and most of the recent very generous rainfall over the remainder of the state. The islands now exist in a more typical strong trade wind pattern with showers focused windward and mountain.

Low stability and strong trades will allow showers to penetrate leeward at times, particularly overnight. The magnitude of the trades will continue to slowly decrease, but will nonetheless remain strong through the forecast period, as renewed mid-level ridging takes shape over the central and north central Pacific.

A couple waves of light/transient freezing rain could be deposited on the summits overnight within any particularly deep trade wind showers, but will not be particularly impactful given that it will be absorbed by fresh snow cover.

Remnant moisture then pivots through the island chain tomorrow and tomorrow night, bringing enhanced trade wind showers beneath mostly cloudy to overcast skies. Mid and high clouds will likely linger for at least the next couple of days, as the slowly evolving large scale pattern changes little through mid-week. Strong trades continue through the forecast period.

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.
