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 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.

Early afternoon, it was a wet morning here in upper Kula, although it has stopped raining, however the clouds look like they could be trying to precipitate again. The temperature here at my place is 66.2 degrees with the relative humidity 78%

606pm, it’s become foggy here in upper Kula, with my thermometer showing 63.1 degrees, and the relative humidity is 75%

Flash Flood Potential:  Expect increasing shower and thunderstorm chances for Kauai and surrounding waters on Saturday night, then spreading eastward to include Oahu 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.

Hawaii’s Broad Brush Weather Overview: Light and variable winds with limited showers will continue through tonight. Southerly winds will increase late tonight into Saturday ahead of a stronger front that will approach from the northwest Saturday night. Enhanced showers and isolated thunderstorms will develop over the western end of the state on Sunday and continue through Monday night. Additional rounds of showers possible mid to late next week as another front approaches, then stalls across the western half of the state.

Hawaii’s Weather Details: The latest surface analysis continues to show a dissipating trough just north of Maui, providing for a slight increase in clouds and showers across the windward Maui waters. Otherwise, conditions were rather tranquil with light and variable winds and limited showers. Little change is expected through most of tonight.

Southerly winds will begin to increase late tonight into Saturday, ahead of a significantly stronger and more moisture-laden cold front. Model guidance remains in fairly good agreement and continues to show the front approaching Kauai County late Saturday, then moving eastward towards Oahu on Sunday, before stalling somewhere over the western end of the state Sunday night into Monday. The main difference between this front and those of recent memory is the increased upper level support provided by a 120 knot southwesterly jet stream.

This jet stream will help deepen the front and provide a narrow corridor of strong uplift. This in turn will result in a mature system that will support the development of a band of heavy rain and isolated thunderstorms. There is still some uncertainty where this band will setup, but based on the latest guidance, there’s now a Flood Watch for Kauai, Niihau, and Oahu from midnight Sunday through late Monday night.

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. Lingering moisture will keep some showers across the area on Tuesday. Another surface low looks to develop near the dateline well west on Monday, then dive southeast towards the islands mid to late next week. The will send another cold front that approaches the state from the northwest, then stalls over the western end of the state.

Fire weather:  Conditions will remain below critical fire weather thresholds through the forecast period. Winds are expected to remain light to moderate, with relative humidity steadily increasing as a front approaches from the northwest late Saturday, then stalls over the western end of the state Sunday and Monday. Additional showers chances expected mid to late next week, as another front approaches, then stalls across the western half of the state.

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.”
