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 Weather Narrative ~~~

 

Glenn’s Tuesday comments:  I’m here at Sea Ranch, CA with my friend Bob.

It’s clear this morning here at the coast, although with high clouds, which are making for a large ring around the moon. The low temperature here was 50 degrees.

Hawaii’s Broad Brush Weather Overview: A broad, building high north of the islands will produce a tight pressure gradient, leading to breezy to windy trades over the next couple days. Enhanced shower activity and cloud coverage will remain mainly over windward and mountain areas. As the high meanders northeastward away from the islands later this week, trades will weaken to more moderate levels for the remainder of the week.

Hawaii’s Weather Details: The latest model guidance continues to support a broad, building high situated well north of the Hawaiian Islands. Currently at 1034 millibars, this area of high pressure produces a tight pressure gradient, the key factor in the recent breezy to windy trades across the state, and forecast to prevail throughout the remainder of the week. Trades are anticipated to be strongest on Wednesday, as the aforementioned high is forecast to build to around 1035 millibars.

This has increased confidence for more widespread windy trades and may exceed wind advisory thresholds beyond the typical wind-prone locations. Thereafter, model guidance suggests the high will begin to weaken, and propagate northeastward away from the islands during the latter half of the week. Trades will respond accordingly, weakening as well, though is expected to remain moderate to locally breezy.

Throughout the week, the enhanced trades will bring periods of shower activity, particularly across windward and mountain areas across all islands. Latest model guidance has depicted a weak low and associated frontal boundary developing east of the island chain early Wednesday, that is set to meander further eastward and dissipate. Prior to dissipating, however, moisture associated with the frontal boundary gets embedded in the enhanced trade wind flow, suggesting an increase in shower activity along windward and mountains areas, namely across Maui and the Big Island. Expect windward trade showers to be prominent throughout the middle of the week, then gradually lessen through the weekend.

A slightly drier air mass will keep dew points in the low- to mid-60’s through the next several days, presenting a more Fall-like ambiance across the islands. Relative humidity values may take a brief hit today and tomorrow, with values falling below 50 percent today, predominately across leeward Big Island, recovering back above 50 percent as the week progresses as additional moisture moves into the state.

In the longer range, by early next week, some models indicate an influx of moisture will be pulled northward and engulf the Hawaiian Islands as a surface trough produces southerly flow.

Fire weather:  Breezy to locally strong trades will continue across the state through the week. Relative humidity may briefly fall into the mid- to upper-40s for isolated leeward areas, however, low-level moisture embedded within the trades should prevent this from being widespread. Additional areas of moisture moving into the state should help to keep relative humidity from reaching critical thresholds for the remainder of the week. Inversion heights will remain around 6,000 to 7,000 feet for the time being.

Hawaii’s Marine Environment: A strong ridge of surface high pressure, centered well north of the islands will maintain fresh to strong trades across all marine waters. In addition, combined seas are expected to be high for windward marine zones and through island channels. Trades are then forecast to further increase tonight through Thursday and become strong to near gale force. A Gale Warning may be need during the peak of the event for the typically windy waters surrounding Maui and the Big Island. The high will gradually drift eastward and weaken Friday, leading to moderate to fresh trades through the upcoming weekend.

A short to moderate period, north-northeast (020-030 deg) swell, generated from strong trades near and upstream of the islands, will produce large and rough surf above High Surf Advisory (HSA) levels along north and east shores. The northerly component to the swell will allow for surges at north facing harbors, mainly Hilo and Kahului.

In addition, a combination of higher than predicted water levels, large breaking waves, and strong onshore winds could lead to significant wave runup, and beach erosion, and localized coastal flooding near high tides for north and east facing shores, then mainly for east facing shores thereafter during daily peak high tide cycle. The HSA will likely be dropped for north facing shores tonight and extended for east facing shores through at least Wednesday night, as large waves and choppy conditions persist from strong to near gale force trades around and upstream of the islands. The advisory may need to be upgraded to a warning during the peak of the event on Wednesday. Northeast swell energy lowers on Thursday as local trade winds begin to decline, with east shore surf steadily dropping Friday through the weekend.

A pulse of long period south swell energy has arrived and can be noted on the near shore buoys. This swell is forecast to peak slightly higher into Wednesday, then begin to fade by Thursday. This late season energy should help bump surf up to near or slightly above the November average. South shore surf returns to near flat Friday into the weekend.

Interesting:  Exploring Climate-Smart Forestry Across Continents

David MacFarlane, a professor of measurements and modeling in the Department of Forestry at Michigan State University, recently completed a six-month sabbatical that took him from the mangrove coasts of Mexico to the alpine forests of Italy. His journey was part of a Fulbright Global Scholar Award aimed at advancing an emerging global approach to forest management known as climate-smart forestry.

Climate-smart forestry integrates forest conservation, carbon storage and sustainable use of forest products to strengthen community resilience and combat climate change. For MacFarlane, the sabbatical was not only about research but also about building meaningful cross-cultural collaborations.

MacFarlane began his sabbatical in Mexico, where he had previously conducted research and leads an education abroad program. This time, he spent two months fully immersed — living in the community, setting up an office at a local institution and working closely with Mexican colleagues and students.
