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

It’s partly cloudy with hazy conditions early this morning, with a low temperature of 51.5 degrees at my place.

1239pm, I played Pickleball in Makawao, and it was off and on rainy. As I drove back here to Kula, the showers got much lighter, and it’s partly cloudy here at my place.

109pm, cloudy with breezy conditions here in upper Kula, with fog and light showers, with the temperature 62.2 degrees.

220pm, it remains cloudy and wet and cool, with a temperature of 60.2 degrees…it’s a bonafide winter day!

737pm, it’s a stormy night here in upper Kula, with the northerly winds gusting strongly at times, and calming right back down at times too.

Hawaii’s Broad Brush Weather Overview:  A stationary front will remain parked over Maui County through Thursday. This feature is expected to bring periods to showery weather to mainly Maui County, and to a lesser extent windward portions of the Big Island and Oahu. More unsettled weather is possible Friday through the weekend for the western islands, as a plume of deep moisture develops ahead of another approaching cold front. Drier weather and improving conditions are forecast by next Tuesday as ridging builds across the area.

Hawaii’s Weather Details:  Satellite imagery shows a complex of lows spinning roughly 1000 miles north and northwest of the state. A deep upper level trough can be noted south of these lows, over the islands, with abundant mid and upper level moisture/clouds streaming over the region from the southwest. Near the surface, the cold front that affected the smaller islands has stalled near Maui County. Gusty northerly flow immediately behind the front, combined with ample low level moisture, allowed for rather impressive rainfall rates and daily totals. Since midnight, Mt. Kaala on Oahu received near 5 inches of rainfall, generally 1 to 2 inches of accumulation on the Ko`olau range, close to 6 inches on the northern slopes of Molokai, and 2 to 3 inches along the northern slopes of Haleakala according to reporting stations thus far.

Short range model guidance keeps the front stalled over Maui County through Thursday. Lift from this boundary, along with moderate northeast flow, may confine shower activity to mainly to windward and mountain areas of Maui County over the next 24 hours, and to a lesser extent windward Big Island and Oahu. Various pulses of energy embedded in the upper trough will act to enhance shower activity over the next several days. One of these pulses is forecast to move across the central islands Thursday morning through the afternoon. During this time, guidance is hinting at heavier shower development. Isolated thunderstorms are possible for Maui County and adjacent coastal waters Thursday morning through the afternoon when instability, though still relatively marginal, is at its greatest.

Through early this weekend, both the GFS and ECMWF models keep the upper trough anchored over the state, with troughs rotating through. The combination of added lift and remnant moisture hanging over the islands will keep us in an active weather pattern with periods of showers. Northeasterly flow will begin to veer easterly Friday night, then southeasterly by Saturday, as the next system begins to approach the islands from the northwest.

Sunday into Monday, long range models agree on pushing a front down the island chain, though there still remains differences in the exact timing and strengthen of the system. The ECMWF pushes a rather weak front down the island chain late Sunday, while the GFS pushes a more robust system down through Monday. Current forecast philosophy is splitting the difference until further details become clearer in the coming days. Post frontal, chilly northerly surface winds should carry in drier air, then veer to northeasterly as transient deep layer high pressure moves north of the state.

Hawaii’s Marine Environment:  Strong north to northeast winds and rough seas will affect the western half of the marine area, as a cold front moves into Maui County. The front will then stall across the central islands, with winds gradually easing and becoming more northeasterly. Around the Big Island, expect gentle east to southeast winds to continue on the south side of the stalled front.

A weak surface ridge will develop a couple hundred nautical miles north of Kauai on Thursday, leading to gentle to moderate easterly trade winds through Friday night. Winds will turn out of the southeast and south over the weekend as another front approaches from the northwest, while a disturbance aloft could trigger a few heavier showers and possibly thunderstorms during this time as well.

Overlapping west-northwest to north-northwest swells will produce surf slightly below High Surf Advisory (HSA) levels for exposed north and west facing shores through Friday. Gusty north to northeast winds will produce rough and choppy conditions along north facing exposures of the smaller islands. A sharp downward trend in north shore surf is expected over the weekend, followed by a potentially large northwest swell arriving Monday night and Tuesday.

East shore surf will remain below seasonal average through the week, although a brief increase is possible on Kauai and Oahu due to strong post-front northerly winds. Surf along south facing shores will remain very small through the week.

Interesting:  Tiny Earthquakes Reveal Hidden Faults Under Northern California

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise to devastating major earthquakes. The work, by researchers at the U.S. Geological Survey, the University of California, Davis, and the University of Colorado Boulder, is published January 15 in Science.

“If we don’t understand the underlying tectonic processes, it’s hard to predict the seismic hazard,” said co-author Amanda Thomas, professor of earth and planetary sciences at UC Davis.

Three of the great tectonic plates that make up the Earth’s crust meet at the Mendocino Triple Junction, off the Humboldt County coast. South of the junction, the Pacific plate is moving roughly northwest against the North American plate, forming the San Andreas fault. To the north, the Gorda (or Juan de Fuca) plate is moving northeast to dive under the North American plate and disappear into the Earth’s mantle, a process called subduction.

But whatever is going on at the Mendocino Triple Junction is clearly a lot more complex than three lines on a map. For example, a large (magnitude 7.2) earthquake in 1992 occurred at a much shallower depth than expected.
