Here’s the webcam for the Haleakala Crater 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 Weather Narrative ~~~

Small Craft Advisory…
all coasts and channels except Maalaea Bay

High Surf Warning…
north and west shores of Niihau, Kauai, Oahu, Molokai, Big Island, and north shore of Maui


Broad Brush Overview: The generally light wind conditions will prompt daytime sea breezes and nighttime land breezes this weekend. Look for afternoon clouds, although with only a few showers, along with mostly clear and seasonably cool nights and mornings. The trades will return Monday, then strengthen and become strong and gusty by Wednesday. Windward and mountain showers may become more frequent Tuesday onward…as the trades increase.

Details: Dry weather prevail, which will remain in place through Monday. Weather maps show the islands in a very weak wind field, between high pressure ridges to the west and east, and a large area of low pressure well to the north. The resulting light wind flow is allowing a nighttime land breeze and daytime sea breeze regime to prevail over the islands. A surface ridge will remain over the state, then drift northward late Sunday through Monday. Trade winds will become more defined Sunday night and Monday into Tuesday onward.

Looking Further Ahead: A robust high will park itself to our north by Wednesday, in the wake of a weak cold front. The front won’t have any influence on our weather, although the building high will cause trade winds to increase significantly, with 25-35 mph winds over the open ocean. Winds this strong interacting with island terrain in a stable environment may require a Wind Advisory. The models then show the trades decreasing somewhat Friday into next weekend…as a weak surface trough develops to the west of the state.

Marine environment details: The extra large northwest swell will build rapidly, bringing surf heights well above warning levels to exposed shores on the smaller islands, and to the Big Island a bit later. Warning level surf will continue through this weekend and possibly into Monday. As the swell subsides, surf should remain at advisory levels into mid-week before…another northwest swell arrives Wednesday night.

A Small Craft Advisory (SCA) is in effect for all Hawaiian coastal waters, except Maalaea Bay, due to seas. A ridge over the state will keep winds light through the weekend. The ridge will move north late Sunday, with moderate to locally stronger trade winds returning at the beginning of the work week. Winds will then increase through the new week.

Extra large swells have the potential to cause significant impacts to shorelines, especially ones already prone to erosion. This type of event usually generates well above coastal overwash, especially when coinciding with high tides. The highest tide throughout the state will occur again between 130 and 300am Sunday morning, with values between 1.6 and 2.6 ft. Additionally, harbors with northern and northwestern exposures could see impacts from potential surging.

Huge Glaciers Found Hiding Beneath Mars Surface
– Sizable deposits of water ice lurk just beneath the surface in some regions of Mars, a new study reports.

The newfound sheets appear to contain distinct layers, suggesting that studying them could shed considerable light on the Red Planet’s climate history, researchers said. And the ice is buried by just a few feet of Martian dirt in places, meaning it might be accessible to future crewed missions.

“I’m not familiar with resource-extraction technology, but this may be information that’s useful to people who are,” study lead author Colin Dundas, of the U.S. Geological Survey’s Astrogeology Science Center in Flagstaff, Arizona.

Dundas and his colleagues analyzed photos captured over the years by the High Resolution Imaging Science Experiment (HiRISE) camera aboard NASA’s Mars Reconnaissance Orbiter (MRO). They identified eight locations where erosion had exposed apparent glaciers, some of which extend 330 feet or more into the Red Planet’s subsurface.

These sites are steep, pole-facing slopes in Mars’ midlatitudes, between about 55 and 60 degrees both north and south of the equator. The ice-harboring areas sport few craters, suggesting they’re quite young, geologically speaking, the researchers said.

Interestingly, scientists think that Mars’ obliquity — the tilt of the planet’s axis relative to the plane of its orbit — has shifted a fair bit over the past few million years, varying between about 15 and 35 degrees, Dundas said. (The Red Planet’s obliquity is currently about 25 degrees; Earth’s is 23.5 degrees.)

“There’ve been suggestions that, when there’s high obliquity, the poles get heated a lot — they’re tilted over and pointed more at the sun, and so that redistributes ice toward the midlatitudes,” Dundas said. “So, what we may be seeing is evidence of that having happened in the past.”

Researchers already knew that Mars harbors subsurface water ice, and lots of it. For example, MRO’s ground-penetrating Shallow Radar instrument recently found a buried ice layer that covers more ground than the state of New Mexico. (NASA’s Phoenix lander also dug up some ice near the Martian north pole in 2008, but it’s unclear if that stuff is part of a big sheet.)

But the newly analyzed HiRISE data give researchers more detailed looks at such deposits, Dundas said.

“The take-home message is, these are nice exposures that teach us about the 3D structure of the ice, including that the ice sheets begin shallowly, and also that there are fine layers,” he said.

The new study was published online in the journal Science.
