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…as of 322am Tuesday:  A breezy to locally windy trade wind pattern persists through the week. Moisture embedded in the trades will periodically deliver clouds and showers to windward and mountain areas. Wetter weather is possible this coming weekend.

Hawaii’s Weather Details…as of 322am Tuesday: Strong subsidence in full swing as evidenced by the rapidly strengthening and lowering trade wind inversion on the most recent atmospheric soundings out of Lihue. This subsidence is driven by building mid-level ridging and strong dry advection. This supports current wind gust observations ranging between 35 mph along the Waianae Coast of Oahu to 40-50 mph in the lee of the West Maui Mountains. Large scale conditions will favor maintenance of downsloping through today.

Meanwhile, the latest ASCAT pass indicates widespread sustained wind observations just shy of 30 knots over the open water immediately upstream of the islands, suggesting that guidance is under estimating winds by several knots. Active subsidence will ease tonight into Wednesday, though the mid-level dry airmass will remain in place in support of a strong inversion. Winds are modeled to undergo little change during the next 36 hours. Strong and stable trades continue through Thursday before stability begins to diminish on Friday.

The week will otherwise be characterized by a rather slowly evolving large scale pattern, that will ultimately lead to potential for several days of wet and unstable trades this weekend into early next week. Presently, upper troughing and convergent SE flow in the low levels maintains a steady moisture feed into a complex of thunderstorms centered southwest. Pressure falls and deepening cyclonic flow associated with evolving troughing west of the Hawaiian Islands will allow this moist SE flow to extend northwestward over the islands Friday into the weekend.

Saturday and Sunday potentially feature moderate to strong moist trades in the lower levels. A flash flooding threat may develop during this time, but forecast confidence will be largely contingent on the expected strength of trades. At this time, guidance indicates the islands residing along the gradient between stronger trades to the east and light SE flow to the west, with plenty of room for error in either direction. It looks like thunderstorms will remain nothing more than an isolated threat. Certainly a scenario worth monitoring as the end of the week draws closer.

Hawaii’s Marine Environment…as of 332am Tuesday: A strong high pressure system far north of the Hawaiian Islands will continue to drift farther south through Wednesday, and then weaken from Thursday onward. This closer proximity to the islands will keep strong and gusty trade winds in the forecast through at least Wednesday. A Gale Warning was issued for windier waters and channels around the island of Maui, as satellite winds showed a large area of gale force winds last night. The Small Craft Advisory remains in effect for all Hawaiian Coastal Waters outside of the gale warning area. A slight decrease in trade wind speeds will develop Thursday into Friday as the high weakens briefly, before another strong high develops far north of the state later this coming weekend.

Surf heights along east facing shorelines will remain solidly within High Surf Advisory (HSA) criteria through Wednesday, driven primarily by a large and persistent fetch of fresh to strong trade winds upstream of the islands. The HSA will continue through Tuesday night, and an extension through Wednesday is looking likely as strong upstream trades are expected to persist.

Surf will remain small along north, west and south facing shores through Saturday, as no significant swells are forecast into the weekend.

In the extended range forecast, forerunners from the next moderate to large, long period north (010-020 degree) swell appear to arrive by late Sunday night, building swiftly to advisory levels through next week Monday, and then slowly declining into the middle of next week. A Harbor Surge Marine Weather Statement may be required for north facing harbors, especially for Kahului and Hilo harbors.

Interesting:  New Research Reveals How Warming Climate Is Changing “Troublesome” Glacier Behavior

A global analysis of glacier surging, led by the University of Portsmouth, reveals the hazards they cause, and how climate change is making their behavior increasingly difficult to predict.

While most of the world’s glaciers are retreating as the climate warms, a small but significant population behaves very differently – and the consequences can be severe.

A team of international scientists, led by the University of Portsmouth, has carried out a comprehensive global analysis of surging glaciers, examining the hazards they cause and how climate change is fundamentally altering when and where these dramatic events occur.

Glacier surges – when a glacier suddenly moves much faster than normal – rapidly transport ice to the glacier front and often cause advances. These events typically last for several years, with many glaciers experiencing repeated surges separated by decades of relative inactivity.
