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.

Glenn’s Monday comments:  I’m here in Bend, Oregon with my friend Bob Earle.

It’s partly to mostly cloudy here in Bend early this morning. The low temperature was a very chilly 22 degrees.

Hawaii’s Broad Brush Weather Overview: As the surface level trough and upper-level low move away from the islands, weak ridging will fill the void aloft well north of the state. Shower trends will decrease a bit from Tuesday into Thursday as a result. Towards the end of the week, an upper-level trough will drop in on Friday, and bring some enhanced trade wind showers ahead of another, weaker cold front advancing southward into the western islands by the weekend.

Hawaii’s Weather Details: A trough, formerly the southward advancing cold front, and accompanied upper-level low immediately behind the trough now sit west of Kauai and are forecast to continue westward away from the Hawaiian Islands throughout the day. With it, much of the moisture has also vacated to the west and away from the western islands.

Remnant isolated showers persist around the state, producing little to no precipitation. As the aforementioned trough and upper-level low exit the vicinity of the islands, upper-level ridging will gradually rebuild north of the state, opening the doors for moderate trades to reestablish beginning Tuesday and prevail through the next couple of days.

Later today, a pocket of tropical moisture will extend north, clipping the Big Island, and bring enhanced shower activity to windward and southeast slopes. Heaviest of showers will be focused over windward Big Island, however, the typical trade wind pattern will likely bring periods of showers to windward and mountain areas on all other islands as well.

Thereafter, latest models suggest another upper-level trough will advance southward toward the islands, escorted by yet another, weaker cold front. Models are projecting that the frontal boundary will approach the islands by the middle of the weekend and stall within the proximity of Kauai and Oahu. Much like this recent cold front, as this one reaches the islands, expect increased cloud coverage and enhanced shower activity to the surrounding islands, as well as a period of relatively gusty winds.

Fire weather: Increased relative humidity values and light to moderate trades will maintain below critical fire weather conditions the next several days. Temperature inversion heights near the Big Island and Maui will range from 7,500 to 8,500 feet for the time being.

Hawaii’s Marine Environment: A trough and upper level disturbance west of Kauai leeward waters will continue to drift westward, decreasing shower activity statewide. Gentle to fresh trade winds will strengthen slightly into the fresh to locally strong range Tuesday through Thursday. High seas will continue for the northwestern coastal waters, and then decline below Small Craft Advisory levels by tonight. The SCA remains in effect for these waters due higher seas.

The High Surf Advisory was cancelled as the north-northwest swell continues to decline just below advisory levels. Looking into the swell future we see pulses of medium and long period swell energy continuing from the northwest to north direction through much of next week. The next north-northwest moderate swell build into the region starting late Tuesday, peaking by Wednesday, and then declining. A brief, overlapping small long period northwest (320 deg) swell will build in from Wednesday night through Thursday. The next moderate to large, medium period northerly (350-020 deg) swell builds into the region from late Friday, peaking on Sunday above advisory levels, before gradually declining into the first half of the week. Another longer period northwest (320-330 deg) swell arrives in time for the middle part of the week.

Surf along east and south facing shores will remain small. Only slight pulses of long period south swell energy are expected over the next seven-days.

Interesting:  Tracking River Pollution: A Novel Approach to Sampling

River pollution is a major threat to water quality and ecosystems, and understanding pollution sources and how they mix is vital to creating effective pollution management. Alex O’Brien tells us about a project testing a new approach to tracing where the pollution comes from…

I’m part of a team of scientists from UKCEH and the British Geological Survey (BGS) involved in a sampling campaign on the Thames to trial a novel integrated method to river sampling. We’re using this approach to investigate nutrient sources and in-stream processes related to pollution from three sources: combined sewer overflows (CSOs), sewage treatment works (STWs), and agricultural runoff.

The work is part of the NERC-funded large grant ‘SMARTWATER’, which is looking at pollution sources and events, how they impact river water quality in catchments, and how we can better predict and manage them.
