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.

Glenn’s Tuesday comments:  I’m here at home in upper Kula, Maui

It’s mostly clear early this morning here at my place, with calm winds, and a very chilly low temperature of 44 degrees , and the relative humidity is 75%.

216pm, this morning I had something called Mohs Surgery down in Kihei, to address a small spot on my forehead, which is now finished and I’m back home. I have to go back Thursday morning to have it repaired (stitched up). It didn’t hurt at all, although I was there 4 hours.

552p, sunny to partly sunny, with clouds along the windward sides. The temperature here at my place in upper Kula is 68 degrees…with the relative humidity 54%

Hawaii’s Broad Brush Weather Overview…as of 358pm Tuesday:  A breezy to windy trade wind pattern will persist through at least Wednesday, then gradually wane through the rest of the week. Moisture embedded in the trades will allow showers to favor windward and mountain areas. An overall wetter pattern is possible this weekend, as additional moisture is drawn over the island chain.

Hawaii’s Weather Details…as of 358pm Tuesday: Strong high pressure remains centered north-northeast of the islands, with a nearly-stationary front located northwest of Kauai. Meanwhile, strong subsidence remains in place over the state. Winds across the state have reached advisory levels (sustained speeds of 30-39 mph and/or gusts 50-57+ mph) across portions of islands at times, especially over higher terrain, passes, and areas immediately south through west of mountains. Latest observations show that the strongest gusts have occurred over the typically windy locations of Maui County and the Big Island, and an advanced scatterometer pass showed 25 knot winds or greater over nearly all Hawaiian waters, with Gales in the windier waters and channels surrounding Maui County and the Big Island.

Though active subsidence will ease tonight into Wednesday, the mid-level dry airmass will remain in place in support of a strong inversion. Winds are expected to remain nearly unchanged as the surface high remains to our north, and the front remains nearly stationary to our west. Based on this, the Wind Advisory has been extended in time through 6pm Wednesday. By Thursday, winds will begin to decrease, but remain locally strong throughout the rest of the work week.

As far as precipitation is concerned, little change is expected over the next few days, with occasional showers and clouds embedded within the trades favoring windward and mountain areas over the next several days. Things begin to get a bit more interesting near the end of the week, as an overall pattern shift could ultimately lead to several days of wet and unstable trades this weekend into early next week.

Latest guidance remains in good agreement that southeast flow in the lower levels could expand moisture over the islands late this week, then stall it over the state for at least Saturday and Sunday. While it is still very early, this will be closely monitored for potential flooding that could develop in this scenario. However, forecast confidence will largely depend on the expected strength of trades, which will in turn modulate forward motion of showers.

The latest guidance continues to indicate that the islands could reside somewhere along the gradient between stronger trades to the east and light southeast flow to the west (though where exactly this sets up could make a large difference in rainfall potential for the islands). Still too early for specifics as there remains a lot of room for error, but something to continue monitoring throughout the rest of the week.

Hawaii’s Marine Environment…as of 358pm Tuesday: A strong high pressure system far north of the Hawaiian Islands will continue to drift farther south through Wednesday, keeping strong and gusty trade winds in the forecast through at least Thursday. A Gale Warning has been extended through Wednesday afternoon for windier waters and channels around the island of Maui, as satellite winds continue to show gale force winds through these areas. 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 may occur Friday and Saturday as the high merges with another strong high developing far north of the state.


Surf heights along east facing shorelines will remain solidly within High Surf Advisory (HSA) criteria through at least mid-week. The HSA is in effect through Wednesday night 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. However, the arrival of a small, medium-period northwest swell may bring a slight increase in surf along north-facing shores late Wednesday through Friday.


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 by next week Monday, and then slowly declining into the middle of next week.

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.
