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 at home in upper Kula, Maui

It’s partly cloudy early this morning here at my place, with calm winds, and a low temperature of 52 degrees at my place, and the relative humidity is 83%.

921am, it’s sunny here in Kula, and most of the leeward areas, with still some low clouds along the windward sides of Maui.

322pm, I played Pickleball in Haiku this morning, where it was cloudy and windy,  although that didn’t stop me from having fun playing. It’s partly cloudy here on Maui, although it’s cloudy around the mountains, and showery along the windward sides.

6pm, partly cloudy with continued passing showers on the windward sides.

830pm, it’s clear here in upper Kula, with the temperature here at my place 55.2 degrees, with the relative humidity 79%

Hawaii’s Broad Brush Weather Overview…as of 829pm Monday:  Breezy to locally windy trade wind pattern persists through the week. Moisture embedded in the trades will periodically deliver clouds and showers to windward and mountain areas, with an increase in shower activity possible this weekend.

Short Term Update…as of 824pm Monday: A band of showers extends from Windward Big Island to the nearshore waters off the coast of Kauai and Oahu at press time. These showers will work through the area during the next several hours, bringing increased showers predominantly to windward and mountain areas. A very dry mid-level airmass beneath building mid/upper ridging will move into the area in the wake of these showers,bringing increased stability and drier air.

The lead edge of this airmass aloft has already pushed into western portions of the state, where the afternoon atmospheric sounding out of Lihue, indicated a rapid strengthening and lowering of the inversion. If anything, this will aid wind gust production as stability and descending air spreads over the state tonight through Tuesday.

Hawaii’s Weather Details…as of 335pm Monday: The high pressure north of the islands was analyzed as a 1040 millibar high, in line with the expected GFS and ECMWF models weakening trend. A few wind gauges, mainly on Maui and the Big Island have been gusting over 40 mph. About half a dozen gauges on each of Maui and the Big Island have had sustained winds in excess of 30 mph today.

As anticipated, the high far north of the islands will maintain the tight pressure gradient over the islands, resulting in breezy to locally windy conditions. The GFS and ECMWF models are in good agreement with this high continuing to sink southward and weaken overnight, however this is not expected to alter the resultant pressure gradient over the region, thus expecting the winds to hold fairly steady into tomorrow. The Wind Advisory remains in effect for portions of Oahu to the Big Island, with the strongest winds in the typical locations of higher terrain areas, passes, and areas immediately south through west of mountains.

A cold front about 850 miles to the northwest of Kauai will continue to move to the east, and by tomorrow, may help to tighten the pressure gradient over the islands between the high and the front. This could cause an uptick in winds tomorrow and Wednesday, which could result in an expansion and extension of the Wind Advisory. Currently several of the high resolution models are depicting winds stronger than observations, which raises concerns about the peak of the winds that are forecast in those models. However most models are indicating winds around advisory levels through much of the week.

Radar shows isolated showers immediately upstream of the islands, with satellites showing some more showery bands further upstream. The southern end of the first of these bands is over the coastal waters to the east of the Big Island, and is likely to begin moving over the Big Island within the next couple of hours. These bands will be carried in on the trades, and keep passing showers focused over windward and mountain areas. However, the stronger trade winds will carry some of these showers to the leeward areas of the smaller islands. Expect similar shower activity to continue through much of the week.

During the second half of the week, the GFS and ECMWF models are in good agreement with moisture being drawn northward to the east of the islands. This moisture then is expected to get carried in on the trade winds, which would increase shower activity for the upcoming weekend.

Hawaii’s Marine Environment…as of 335am Monday: A strong high pressure system far north of the Hawaiian Islands will continue to drift farther south through Wednesday. This closer proximity to the islands will keep strong and gusty trade winds in the forecast through at least Wednesday. A slight decrease in trade wind speeds may develop Thursday into Friday as the high weakens briefly.

Surf heights along east facing shorelines will remain solidly within the High Surf Advisory (HSA) range through Wednesday. The HSA was extended until Tuesday evening for now, and may need to be extended into Wednesday.

Small surf heights remain in the forecast for north, west and south facing shores lasting into Saturday, due to an absence of significant swell energy in the medium range forecast.

In the extended range forecast, the forerunners of the next moderate to large, long period north (010-020 degree) swell appears to arrive by late Sunday night, building swiftly to advisory levels through next week Monday, and then slowly declining into the middle of next week.

Interesting:  Sea Turtles are Nesting Earlier – but Producing Fewer Eggs, Less Often: New Research

A new 17-year study of loggerhead sea turtles nesting in Cabo Verde reveals exactly this tension. Researchers from Queen Mary University of London and conservationists from NGO Associação Projeto Biodiversidade report that warming oceans are triggering earlier nesting in one of the world’s most important loggerhead turtle populations. Yet at the same time, declining ocean productivity is reducing how often females reproduce and how many eggs they lay.

The study, published in Animals, shows that climate change impacts sea turtle reproduction through multiple, interacting pathways.

“Sea turtles are adjusting their timing to warmer temperatures, which shows a remarkable capacity for flexibility,” says Fitra Nugraha, the study’s lead author at Queen Mary University of London. “But at the same time, the part of the Atlantic oceans they depend on for food are becoming less productive – and that is quietly eroding their reproductive output.”
