Hawaii’s MountainsHere’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.

I played a couple of games of very lively Pickleball this morning, with some advanced players from the area, who happened to be 20-30 years younger than I am.

We sat out on the deck and had a glass of wine, and watched the low stratus and fog moving north along this coast. We’re looking forward to an active storm system approach this area over the next couple of days. I’m hoping I can sneak in a couple of quick games tomorrow morning before the rains and wind arrive.

You Veterans, those of you who are alive and those of you who have passed away, thank you for the service to your country. I happen to be a Veteran myself, as I was drafted and was sent to Vietnam way back when.

 

Hawaii’s Broad Brush Weather Overview: A broad high far north of the Hawaiian Islands will keep breezy to windy trades in the forecast through late Wednesday. Enhanced shower activity and cloud coverage will remain focused over mainly windward and mountain areas. Trades will weaken, becoming moderate to breezy by Friday, as the high moves towards the northeast and weakens later this week.

Hawaii’s Weather Details: The latest surface analysis places a broad 1036 millibar high far north of the Hawaiian Islands. This is keeping breezy to locally windy trades blowing across the islands, with some of the wind prone areas on the Big Island and Maui briefly exceeding wind advisory criteria of 30 mph. Trades are expected to increase late tonight into Wednesday as the pressure gradient across the state tightens, with more widespread and persistent winds exceeding advisory criteria. Based on the latest guidance, a Wind Advisory has been issued for portions of Maui County and the Big Island. The strongest winds are expected to continue through Wednesday night, then slowly weaken and become moderate to breezy by Friday, as the high drifts towards the northeast and weakens.

Throughout the week, the enhanced trades will bring periods of shower activity, particularly across windward and mountain areas. Guidance continues to show an increase in shower activity on Wednesday, as an area of moisture associated with a dissipating front gets embedded in the trade wind flow, with the bulk of the moisture aimed at Maui and the Big Island. GFS total precipitable water continues to show around 1 to 2 standard deviations above normal during this time, while the ECMWF shows 0 to 1 standard deviations above normal. Either way, windward trade showers to be prominent through the week, then gradually lessen heading into the weekend.

A slightly drier air mass will keep dew points mainly in the mid 60’s through the week. A few hours of lower relative humidity is once again possible late Wednesday morning, as guidance shows a transient dry slot moving across the state. This should be short-lived as the low-level moisture embedded in the trades moves in by Wednesday afternoon. Additional areas of moisture should help to keep relative humidity elevated through the rest of the week.

In the longer range, by early next week, some model guidance indicates an influx of an abundant area of moisture pulled northward, engulfing the Hawaiian Islands as a surface trough produces southerly flow. Models during this time are suggesting precipitable water values upwards of 3 standard deviations above normal…the first indication that heavy rainfall may be in store with time. However, confidence remains low at this time, given the long lead time before the event.

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.
