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’s Broad Brush Weather Overview: A cold front advancing down the island chain this morning is bringing gusty northerly winds near and west of the boundary and showery conditions. The front is expected to stall and gradually weaken around Maui County later today through Thursday, bringing additional periods of showery weather. Rainfall chances will trend up statewide Friday through the weekend, as another cold front and upper disturbance approach and move into the area. Conditions should gradually improve from west to east through the first half of next week, as high pressure builds eastward over the area.

Hawaii’s Weather Details: A line of showers associated with a cold front that moved through Kauai is now moving over Oahu. Peak rainfall accumulations over the past 6 hours ranged from 4 to near 7 inches along north- through west-facing slopes of Kauai. In addition to localized heavy rainfall accompanying the boundary, a band of strong northerly winds is occurring along and behind the front, with some of the windier locations on Oahu and Kauai reporting gusts to around 40 mph. Similar conditions are expected through the morning hours as the boundary progresses eastward into Maui County.

Guidance has initialized well with the current synoptic pattern and depicts the front stalling and lingering near Maui County by Thursday. A broad upper-level trough, with several pulses rotating through its base, will support periods of lingering showery weather along the moisture axis over the next few days, particularly over windward and mountain locations with the northeast flow in place.

Despite some remaining differences among the models, agreement has improved considerably compared to 24 hours ago. The majority of solutions indicate low-level flow will shift out of the southeast, as another frontal system approaches the islands over the weekend. Increasing instability aloft associated with the upper trough, combined with deep moisture pooling northward across the islands, will support a wet pattern through the weekend. Conditions should gradually improve through the first half of next week as this system moves through, and drier air moves in as surface high pressure builds to the north in its wake.

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.
