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’s Broad Brush Weather Overview:  A stalled cold front will persist over Maui County today, continuing to bring periods of shower activity, namely to Maui County and windward portions of the Big Island. Unsettled weather resumes this weekend, as another slower-moving front meanders over the islands. Conditions improve, drying out the islands beginning early next week as a surface high builds north of the islands.

Hawaii’s Weather Details:  The stalled front bisects the Hawaiian Islands along Maui County, and will persist through much of the day, and will continue to bring periods of showers to predominately Maui County and windward portions of the Big Island. Latest model guidance depicts upper-level troughing with a series of complex lows, will maintain these lingering showers along the moisture axis associated with the aforementioned stalled front over the next several days, namely across windward and mountain locations as northeastern flow prevails.

As the weekend approaches, model guidance of the GFS and ECMWF supports a relatively active weather pattern, with periods of shower activity for the islands. Northeastern flow will begin to veer southeasterly during this time in response to the next, slower-moving frontal boundary approaching the islands from the northwest, associated with a deep low well north of the islands meandering toward the Gulf of Alaska.

Model total precipitable water (PWATs) connected with this next frontal boundary are on the range of 2 to 3 standard deviations higher than average. Increasing instability aloft combined with deep moisture pooling northward across the islands, associated with the aforementioned system will sustain a wet pattern through the weekend.

By early next week, conditions will begin to improve as the frontal boundary exits to the east, and a drier airmass fills the void as a surface high builds just north of the islands with extensive ridging aloft.

Hawaii’s Marine Environment: Light to moderate northeast winds will persist into Friday across most waters, as a stalled frontal boundary gradually diminishes over the eastern end of the state, and high pressure builds to the north. The exception will be over the Big Island waters east of the boundary, where light east to southeast winds will prevail. Guidance indicates a progressive pattern continuing into the weekend, with a front approaching and moving through the area Sunday into Monday, followed by another front approaching by mid-week. The weekend front could bring locally heavy showers to portions of the marine area, along with a period of moderate to locally fresh southwest kona winds.

Surf along exposed north- and west-facing shores will remain near advisory levels into Friday, as overlapping west-northwest and north-northwest swells move through. Offshore buoy observations reflect this mixed swell regime, with north-northwest energy in the 1012 second range and west-northwest energy holding in the 13-15 second bands. Guidance shows these swells easing late Friday into the weekend, with a small, long-period northwest swell arriving late Saturday.

Surf along east-facing shores will remain small into next week, due to the lack of persistent trade winds locally and upstream.

Interesting:  Measuring Movement Creates New Way to Map Indoor Air Pollution

University of Birmingham scientists have developed a new way of measuring and analyzing indoor air pollution that – in initial trials – has established a clear link between office occupancy, physical activity, and air quality.

Using radar-powered movement detectors and low-cost pollution sensors, researchers equipped office space in central Birmingham to monitor the number of people present and measure the kinetic energy they generated as they went about their work.

One of the most important, yet insufficiently studied, sources of indoor air pollution is particulate matter (PM) that is made airborne through occupants’ movements. Particulate matter trapped within carpeting, furniture, office equipment, and people’s clothes and shoes becomes airborne in indoor environments through human activity.
