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.

~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Aloha Friday comments:  I’m here at home through the winter in upper Kula, Maui

It’s clear to partly cloudy here in Maui County early this morning, with a low temperature of 52.5 degrees at my place, with the relative humidity 80 percent.

Flash Flood Potential:  Expect increasing shower and thunderstorm chances for Kauai and surrounding waters on Saturday night, then spreading eastward to include Oahu and Maui County as well on Sunday. The best chances for heavy rain and thunderstorms will be Sunday night through Monday night. Lingering moisture will remain in place, however, with an overall wetter period through at least next Wednesday.

Incredible Lava flow Fountain on the Big Island – December 6th

 

Hawaii’s Broad Brush Weather Overview: Remnants of a cold front linger between Maui County and the Big Island, and will continue to dissipate, limiting rainfall across the state today. Light, southerly winds will prevail across the Hawaiian Islands through early tomorrow ahead of a stronger, more moisture-laden front Saturday night from the northwest. As a result, enhanced showers and thunderstorms develop over the western end of the state, persisting through Tuesday.

Hawaii’s Weather Details: Latest observations from satellite imagery show the remnants of a front between Maui County and the Big Island will continue to dissipate. Radar imagery shows little rainfall associated with the front, granted most of the rainfall fell over portions of Oahu and Molokai throughout much of yesterday, as the front initially advanced across the islands. Winds across the Hawaiian Islands remain light, allowing sea breezes to develop through the day. Consequently, today should remain relatively dry, though a few lingering showers remain possible, namely across Maui County, where low-level moisture persists.

Additionally, latest observations from the Mauna Kea Weather Center continue to display advisory-level winds across the summits. Because of this, the current Wind Advisory for the Big Island Summits.

As the weekend approaches, winds will begin to pick up a bit from light to more moderate, and veer south across much of the state. Latest model guidance of the American model (GFS) and the European model (ECWMF) depicts another front advancing toward the islands from the northwest again, this one significantly stronger than the previous one, and more moisture-laden, posing a bigger concern for the impacted islands.

Guidance continues to depict an array of enhanced showers and periodic thunderstorms associated with the advancing front, initially to Kauai and surrounding waters Saturday night, then proceeding eastward to Oahu and Maui County by Sunday. The heaviest of the rainfall is expected to develop Sunday night through Monday, posing a potential threat for flash flooding, but this will largely hinge on the position of the heavy rain band, as the front stalls somewhere over the western end of the state.

Upon the departure of supporting upper dynamics on Tuesday, the surface low escorting the front toward the Hawaiian Islands will move far north and weaken, leaving the frontal moisture band over the area through the latter half of the week. Some lingering showers will remain possible during this time. Otherwise, expect light to moderate southerly winds to prevail well into the future.

Fire weather:  Conditions remain below critical fire weather thresholds through the next several days. Winds are expected to remain light to moderate with relative humidity values steadily increasing associated with an incoming front. Temperature inversion heights over Maui and the Big Island will range from 5,500 to 6,500 feet for the time being.

Hawaii’s Marine Environment: The remnants of a dissipating front over the eastern nearshore waters will generally maintain light variable or northerly breezes through the afternoon. As the islands fall downstream of the next approaching front from the northwest, gentle winds will veer around to the east southeast by tonight and become more southerly Saturday. This front is expected to come across the western island coastal waters late Saturday into early Sunday. Southwest winds along or ahead of the front may briefly strengthen to Small Craft Advisory (SCA) magnitudes around the islands of Niihau and Kauai Saturday night. Numerous showers with locally heavy rain and isolated thunderstorms are possible in association with this weekend’s frontal passage. A moderate size northwest swell passage Sunday and Monday will likely elevate seas to SCA levels.

A moderate size, medium period northwest swell (330 degree) that peaked will be gradually declining through Saturday. A north pulse (350 degree) will move through into Saturday. This will hold head high (or slightly higher) surf within the higher sets going into the weekend. A developing gale low just northwest of the offshore waters will send a similar moderate size, medium period northwest (310 degree) swell toward the state. This swell is scheduled to pass around the island chain Sunday and Monday, and lift surf back up to High Surf Advisory (HSA) heights. A mix of smaller size, medium period north swells (350-010 degree) will arrive this weekend. These swells will assist in maintaining at least head high surf along many better northern exposed reefs into early next week.

East shore surf will remain small the next several days due to the absence of trade winds. Eastern exposures better exposed to north swell will experience an increase in seas. Expect minimal surf for south-facing shores. Southwestern exposures on primarily Kauai and Oahu may receive small to moderate choppy wind wave swell this weekend, from strengthened southwest winds ahead of an approaching front.

Interesting: The People Behind Earthquake Early Warning

Alders, alders, everywhere.

When you follow scientists in the Alaska wilderness, you’ll almost certainly get alder-snagged.

In November, near Homer, alders grew considerately on Grewingk Glacier till, with space to maneuver ourselves and our heavy packs.

A few days later, on Kodiak Island, the alders were a bit more rude. My fieldwork companion, University of Alaska Fairbanks doctoral student Cade Quigley, burst through yet another alder thicket and announced that we had arrived: “Here’s the last mud pie.”
