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 in upper Kula, Maui

It’s mostly clear with a few clouds here in Maui County early this morning, with a low temperature of 52.5 degrees at my place, with the relative humidity 79 percent.

650am, there’s an area of clouds and rain, some of which is heavy, to the south and southwest of Maui, which appears to be approaching the County…and could bring some rainfall our way.

235pm, it’s very cloudy over and around the mountains, with more favorable conditions down closer to the coasts. Here in upper Kula, it’s been showering off and on most of the day so far. The temperature here at my weather tower is 67.6 degrees, with the RH 74%

410pm, chilly rain here in upper Kula…63.8 degrees with 77% RH

Interesting Web blog: Mauka Showers – Recap – Our First Big Rain Event of the Wet Season

 

Hawaii’s Broad Brush Weather Overview: Showers and thunderstorms will continue into tonight, mainly over the western islands. Light southeast surface winds will give way to increasing trade winds late Saturday through Monday. A new area of increased moisture will move in Monday and Tuesday, with mainly windward showers. Southeast winds are likely to return late next week, but without as much moisture as our current situation.

Hawaii’s Weather Details: Showers with isolated thunderstorms have covered parts of the state, including a strongly rotating storm over Niihau early this morning. The rotation was strong enough to have produced a tornado, but due to the location of the event, we will likely never know if one actually occurred. Heavy rain was reported in several locations, including central Oahu, and flood advisories were in effect for Kauai and Oahu. Showers have moved mostly offshore at the moment.

Additional showers and thunderstorms are in the forecast for tonight into early Saturday, and models show the main risk will remain over the western islands. With light low-level winds, the enhanced moisture that has impacted the state this week will still be with us tonight into Saturday. Episodes of brief moderate to heavy rainfall remain possible.

An important change in the weather is nearly here. After light southeast winds tonight into early Saturday, trades will arrive late Saturday. They will become stronger out of the east Sunday, and even stronger from just north of east Monday. A new area of enhanced moisture will move in from the ENE around this time, enhancing windward showers into early Tuesday.

Trades are forecast to last through Wednesday night, with indications of a possible return to southeast flow late Thursday into next Friday.

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.”
