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, Hawaii.

It’s clear to partly cloudy here in Maui County this morning. The low temperature here at my place was 56 degrees.

1251pm, just back from Kihei, having to have my quarterly Dermatology appointment. Unfortunately, I had a spot on my cheek that needs to have a biopsy, otherwise, my skin didn’t have any other problem areas. It was 87 degrees while I was down there, and now back here in upper Kula, the temperature is a much more comfortable 73.7 degrees.

6/17 KAHIKINUI FIRE UPDATE AS OF 7 P.M.

FIRE UPDATE
The Kahikinui brush fire mauka of the highway near Mile Marker 24 and 25 reached 95% containment at 330 acres as of 7 p.m. today, 6/17, according to County of Maui Department of Fire and Public Safety (MFD). Crews today extinguished hotspots and reinforced control lines on the south, east and mauka flanks of the fire. No injuries or structural damages have been reported. Moving forward, MFD will issue public communication as necessary on the Kahikinui fire; this is the final update directly from the County’s Maui Emergency Management Agency (MEMA).

ROAD REOPENS
Maui Police Department reopened Pi’ilani Highway (Highway 31) tonight at 7 p.m., and it will REMAIN open, barring emergencies. Motorists should be advised that MFD resources will be stationed in the area overnight to monitor fire conditions. In general, area residents and other drivers should travel with caution due to firefighting apparatus deployed for response to the blaze.

RESOURCES
Personnel will monitor and patrol the fire overnight. Today, two MFD callback crews with wildland apparatuses, engines, tankers and other apparatuses, along with Air One and Air Two, worked to accomplish full containment. County Department of Public Works issued three tankers. And a dozen State Department of Land and Natural Resources Division of Forestry and Wildlife firefighters continued to address hotspots and bolster the perimeter.

Hawaii’s Broad Brush Weather Overview:  High pressure to the northeast of the Hawaiian Islands will remain in place and strengthen by the end of the week. Breezy trade winds and a typical windward and shower distribution can be expected with occasional pockets of showers, mainly during the night time hours. Conditions could then become drier and more windy by the weekend, followed by moderately wet trade winds next week.

Hawaii’s Weather Details:  Passing showers have been observed on radar and satellite imagery over windward and mountain areas. The sounding shows moderately moist air beneath a 6,000 to 8,000 ft inversion, which should support continuing trade wind showers overnight. Our airmass will dry out Wednesday, and periodically fluctuate between periods of slightly wet and dry through the rest of the week, with showers focusing primarily over windward and mountain areas.

Wind speeds appear to hold steady, before gradually decreasing a notch Wednesday through Friday into the moderate to locally breezy range. The next batch of enhanced trade wind moisture looks to arrive around Thursday night through Friday morning, before drying out by Friday evening.

This weekend, high pressure northeast of the islands is forecast to strengthen, which could cause trade wind speeds to increase to breezy to strong levels. Additionally, a strong mid level ridge could move overhead along with a dry airmass. This could inhibit clouds and showers, as well as lower the relative humidity.

These factors combined could increase fire risk, although conditions won’t quite be at red flag warning criteria, however there will still be a risk for enhanced fire weather conditions. More confidence will emerge as the weekend draws closer.

By early next week, dry conditions could be replaced by a wetter trade wind pattern, as global models indicate an upper level low, along with slivers of enhanced low level moisture could move in from east to west.

Hawaii’s Marine Environment:  High pressure north of Hawaii will slowly move eastward and drive fresh to strong trades across the local waters. Trades will weaken slightly Wednesday through the rest of the week, as the aforementioned high becomes anchored northeast of the islands. A Small Craft Advisory (SCA) has been expanded to cover much of the coastal waters. However, for Wednesday through the remainder of the week, the SCA will likely be scaled back to just the windier waters and channels near Maui and the Big Island.

Surf along the south facing shores will be small, as the current small, medium period, south swell fades. A small, long period, south swell will arrive on Wednesday, and bring a slight rise in surf through the weeks end.

Rough and choppy conditions along east facing shores will continue this week. Surf will remain nearly flat along north facing shores throughout the forecast period.

According to the NHC Advisory number 6A

Erick is moving toward the northwest near 7 mph. A northwestward motion with a gradual increase in forward speed is expected over the next couple of days. On the forecast track, the center of Erick is expected to approach the coast of southern Mexico Wednesday night and move inland or be near the coast on Thursday. Maximum sustained winds are near 60 mph with higher gusts. Rapid strengthening is forecast during the next day or two, and Erick is expected to become a hurricane by by early Wednesday. Erick is forecast to be near or at major hurricane strength when it approaches the coast of southern Mexico Wednesday night and Thursday. Tropical-storm-force winds extend outward up to 90 miles from the center.

Interesting:  Strange Radio Pulses Detected Coming From Ice in Antarctica

A cosmic particle detector in Antarctica has emitted a series of bizarre signals that defy the current understanding of particle physics, according to an international research group that includes scientists from Penn State. The unusual radio pulses were detected by the Antarctic Impulsive Transient Antenna (ANITA) experiment, a range of instruments flown on balloons high above Antarctica that are designed to detect radio waves from cosmic rays hitting the atmosphere.

The goal of the experiment is to gain insight into distant cosmic events by analyzing signals that reach the Earth. Rather than reflecting off the ice, the signals — a form of radio waves — appeared to be coming from below the horizon, an orientation that cannot be explained by the current understanding of particle physics and may hint at new types of particles or interactions previously unknown to science, the team said.

The researchers published their results in the journal Physical Review Letters.
