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 home here in upper Kula, Maui, I hope you have a great Tuesday wherever you happen to be spending it.

519am, partly cloudy early this morning…the low temperature here at my Kula weather tower was 57.5 degrees.

1pm, sunny to partly sunny in general, with brisk trade wind blowing in those areas most exposed to the trade winds. Here in upper Kula, the breezes are much lighter, with my temperature here in upper Kula 76.8 degrees…compared to the warmer 87 down at the AP in Kahului.

447pm, It’s one of those very sunny afternoons, and with the light winds here in upper Kula, it feel hot, although the temperature is still rather mild mannered at 77.9 degrees. In contrast to the light winds outside of the more exposed areas…there was a 49 mph gust down at the Kohala Ranch on the Big Island!

825pm, the clouds are clearing nicely, although I missed seeing the comet again, due to the cloudiness right after sunset. My high temperature today was 79 degrees, and at the time of this writing it’s dropped to 61.7 degrees.

 

Hawaii’s Broad Brush Weather Overview:  Fresh to locally strong trade winds will carry in brief clouds and showers over the islands. Showers increase Wednesday night through Friday night, as a mid-level trough moves through, while winds taper off Thursday night into Friday. A drier trend is expected this weekend with strengthening trade winds.

Hawaii’s Weather Details:  Fresh to locally strong trade winds will continue through Thursday under a broad high pressure ridge. An advancing cold front well north of Hawaii will move the high pressure system further from the islands, resulting in a slight weakening of the wind speeds Thursday night.

Meanwhile, a nearly stationary deep low pressure system will set up northwest of Hawaii. Both the distant front and low will keep winds moderate and slightly veered east-southeasterly from Thursday into Friday. Island terrain blockage under this wind pattern will further weaken the winds across leeward areas, resulting in localized sea breezes and interior clouds Friday afternoon before the trade winds strengthen back this weekend.

Trades will carry in brief clouds and showers over the islands through Wednesday. A mid-level trough will move onto the windward and southeast Big Island Wednesday night, spreading westward during the second half of the week. This feature will bring an increase in clouds and showers through Friday night.

A weak upper level low moving into position northeast of the state during this time may also enhance the incoming showers. The forecast will trend drier with a continuation of the moderate east southeast flow from Saturday into the middle of next week.

Hawaii’s Marine Environment:  A ridge of high pressure north of the state will keep fresh to strong trades in place through Wednesday. The trades will ease slightly Thursday through Saturday, as an approaching cold front weakens the ridge north of the islands.

A Small Craft Advisory (SCA) is now in effect for all coastal waters due to winds and/or elevated seas. The SCA continues through 6pm Wednesday due to strong winds for most waters from Oahu eastward. The SCA will likely need to be extended through at least Wednesday night for the windier waters around Maui and the Big Island.

The current moderate to large north swell will slowly decline through the remainder of the work week. A High Surf Advisory remains in effect for most north facing shores across the state. Surf along west facing shores will remain slightly elevated, with the influence of the north swell during the next couple days.

East shore surf will increase a bit into Wednesday, in response to strengthening trades over and upstream of the islands. The surf will then trend lower Thursday through the weekend, as the trades ease a bit. However, east facing shores exposed to the north swell will continue to see some wrap during the next couple days. South shore surf will remain small with mainly background south and southeast swells during the next week.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

 >>> Central Tropical Atlantic:

Invest 94L

An area of low pressure located over the central tropical Atlantic is producing disorganized showers and thunderstorms. This system is forecast to move generally westward, and environmental conditions appear marginally conducive for gradual development by the middle to latter part of this week. A tropical depression could form as the system begins moving west-northwestward and approaches or moves near the Leeward Islands late this week.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…medium…50 percent

Caribbean Sea:  There are no active tropical cyclones

 >>> Western Caribbean Sea:

Showers and thunderstorms in the southwestern Caribbean Sea are associated with a broad area of low pressure. Some gradual development is possible if the system stays over water while it moves slowly northwestward towards Central America. Regardless of development, locally heavy rainfall is possible across portions of Central America later this week.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 7 days…low…20 percent

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific:  There are no active tropical cyclones

Interesting:  A Forest Fire in Western Wyoming

Smoke billowed from a fire in the forests of western Wyoming in early October 2024. High winds and low humidity helped the Pack Trail fire spread over 60,000 acres, forcing people to evacuate from cabins, homes, and ranches west of Dubois, Wyoming, according to local news reports.

Lightning ignited the fire on September 15, and it continued to burn over three weeks later in both the Bridger-Teton National Forest and the Shoshone National Forest. By October 6, gusty winds of up to 60 miles (97 kilometers) per hour helped the fire spread 7 miles eastward, chewing through timber on the slopes near South Fork Fish Creek. This image, acquired by the MODIS (Moderate Resolution Imaging Spectroradiometer) instrument on NASA’s Aqua satellite, shows smoke streaming from the region on October 7.

Smoke darkened the air of valleys and towns both east and west of the blaze. As it flowed into the valley of Jackson Hole, the smoke prompted hazardous air quality alerts in Grand Teton National Park and elevated air quality concerns elsewhere. In downtown Jackson, 30 miles west of the fire, particulate matter made the air “unhealthy” on October 8 and 9, according to the U.S. Environmental Protection Agency’s AirNow Fire and Smoke Map. To the east of the flames, the smaller town of Dubois also had “unhealthy” air on those days.
