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 weakening trough near Kauai will continue to bring showers to the Garden Isle today. Thunderstorms have been added to the forecast for the central islands (Maui County and Oahu) and the surrounding waters, as thunderstorms have developed and are moving northward. Additional moisture moving into the islands will continue the chance for showers statewide through the weekend.

Southerly winds through the weekend will give way to returning trade winds Monday, which will carry showers into the islands early next week.

Hawaii’s Weather Details: A northeast to southwest oriented trough near Kauai brought showers and thunderstorms to the area overnight. While additional showers and even some thunderstorms remain possible, the main threat for flooding has diminished, and so the Flood Watch was cancelled.

Thunderstorms remain in the forecast for today over and around Kauai, however there are some indicators in the models to suggest that thunderstorms could still be possible tonight and tomorrow, and even over the central islands.

The trough is expected to weaken over the next 24 hours, although southerly winds will continue over the region. This will continue to bring moisture up over the islands into Saturday. A surface low developing about 1100 miles northwest of Kauai on Saturday will help to bring additional moisture northward, however the low is expected to stay far to the northwest of the islands, so not expecting those showers to impact us.

Sunday should see our winds become southeasterly, and by Monday look for trade winds to filter back into the islands. As the trade winds build back, moisture upstream will be carried in on the trades, bringing showers back to the more typical windward and mountain areas.

During the second half of the week, the high pressure responsible for the returning trades is expected to be sinking southward, which will shift our winds to a more southeasterly direction. We will need to monitor future models runs to determine any significant changes in shower activity.

Fire weather:  Showers will continue, along with light southerly winds and generally high relative humidities. This will keep conditions below critical fire thresholds through the next few days. Longer range forecast show little chance for dangerous fire weather well into next week.

Hawaii’s Marine Environment: A surface trough, near Kauai, will continue to bring scattered to numerous showers to much of the coastal waters with isolated thunderstorms possible over the western waters. Aside from any gusty winds associated with passing thunderstorms, generally gentle to locally moderate southerly winds will prevail east of the trough.

By late this weekend, easterly trade winds will gradually build from east to west with the potential for SCA conditions over the windier waters and channels around Maui County and the Big Island. Expect trades to strengthen further early next week, as surface high pressure builds to the north.

The current moderate, medium period, north-northwesterly swell (340-350 deg) peaked and has been slowly fading. However, this north-northwest swell will remain elevated and keep surf just shy of advisory levels through early Saturday. A moderate, medium period, northerly swell is forecast to enter the waters late Saturday and may bump surf back up to near advisory levels Saturday night into Sunday. Sunday night into early next week, the swell fades and should allow surf to drop to below seasonal averages.

East facing shores will remain small given the lack of trade winds upstream of the islands, but areas exposed to the north swell will see an increase through the rest of the week. As trade winds gradually strengthen later this weekend, east facing shores could become rough and choppy Sunday through early next week. Surf along south facing shores will remain small through the weekend into early next week.

Interesting: A Wrinkle Beneath the Icy Face of Alaska

A few days ago, the forces beneath Alaska rattled people within a 500-mile radius: A magnitude 7 earthquake ripped under Hubbard Glacier.

The earthquake’s main shock and aftershocks have revealed something else — a possible slash across the face of Alaska long buried by glacial ice, a feature that professionals speculated upon decades ago.

Before getting to that, here’s a review from State Seismologist Michael West on the significance of an earthquake this big:

“We get so numb to magnitude scale in this state,” he said at the University of Alaska Fairbanks, where he works for the Geophysical Institute. “A magnitude 7 is one hell of an earthquake. Put that in Afghanistan, it would kill 10,000 people.”
