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 Thursday comments:  I’m home here in upper Kula, Maui, Hawaii. I hope you have a good day wherever you happen to be spending it.

It’s clear here in upper Kula early this morning, while the low temperature was a chilly 47.5 degrees.

208pm, I was over in Haiku this morning for a couple of hours…I sometimes forget how special that part of the island is! BTW, there’s a bit of volcanic haze (vog) in the air here in Maui County.

520pm, clear to partly cloudy with pretty thick vog. The temperature is 67 degrees, after a high of 73 degrees.

856pm, the clouds are clearing now, as they typically do this time in the evening. It was a very typical day here in upper Kula, with the early evening clouds dropping just a few very light showers. The temperature at the time of this writing was 61.5 degrees.

Weather Wit of the day:  Sunburn – Backin’ and aches

 

Hawaii’s Broad Brush Weather Overview:  Light winds and dry conditions prevail for the next several days, bringing a prolonged stretch of fair weather. Haze is possible for a few days due to vog emissions from Halemaumau vent on the Big Island. A cold front will approach from the northwest late next week, bringing a chance of showers to the state.

Hawaii’s Weather Details:  A strong Pacific jet stream extends across the north central Pacific, along with an expansive ridge of high pressure established to its south, including over the Hawaiian Islands.

The trade wind belt remains suppressed mostly south of the state, with a surface ridge axis in place north of Kauai. This pattern supports moderate trades over the eastern end of the state decreasing to light trades over the western end where afternoon sea breezes and overnight land breezes will be common.

Meanwhile, active mid-level subsidence (sinking air in the atmosphere), light winds, and not much of an apparent upstream moisture source, favor dry and benign weather conditions through the forecast period.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Hawaii’s Marine Environment:  A ridge north of the Hawaiian Islands will keep moderate to locally fresh easterly trade winds in the forecast. The ridge will weaken into Friday, as a shallow cold front approaches the islands from the northwest.

The existing large west-northwest swell will decline tonight as another west-northwest swell builds in, pushing surf heights back up over advisory levels for exposed north and west facing shores.

Small surf is expected along east facing shores this week, as winds remain light. Surf along south facing shores should see a small boost, as a small south swell fills in through the end of the week.

Interesting:  How to Prevent the Next Water-Treatment Crisis

Treatment plants use a combination of tools to keep toxins and contaminants out of drinking water.

Researchers with the University of Cincinnati examined the benefit of two such tools in addressing a toxin produced by harmful algae blooms, which are becoming increasingly common in waters around the world.

Blue green algae can reproduce en masse in waters laden with nitrogen, phosphorus or other excess nutrients. These algae “blooms” also can form when water levels drop during droughts or when bottom sediments heavy with nutrients get churned up in a storm, said Minghao Kong, a doctoral graduate of UC’s College of Engineering and Applied Science.
