Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions.

We see what’s left of former tropical depression Enrique
well to our east, along with former tropical depression
Dolores offshore from Southern California…and a new
tropical system almost ready to form offshore from the
Mexican coast – all in the eastern Pacific

We see the swirl of clouds associated with former
tropical depression Enrique to the east of us…with
thunderstorms west, southwest and south of Hawaii

~~~ Hawaii Weather Narrative ~~~
The trade winds will become lighter through mid-week. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profiler of the central Pacific. We find a fairly strong, near 1035 millibar high pressure system to the north of the state…moving southwest. Meanwhile, there are tropical disturbances/troughs well west and east of the state. The trade winds are expected to continue, although be lighter through the middle of the week, resulting in a mixture of lighter trades…and daytime sea breezes. The forecast has the trade winds rebounding Thursday into the weekend.
There will be showers falling locally at times. There’s a chance that a few of the afternoon showers will be enhanced enough, that they could become rather generous…with even a chance of thunder on the Kona slopes of the Big Island. This modified convective weather pattern will last through Wednesday. As we push into the second half of the week, a more typical trade wind weather will return, with mostly windward showers taking over then. There’s the chance that the remnant moisture associated with former TC Enrique, may eventually get carried into the state on the trade winds later this week…stay tuned. I’ll be back with more updates on all of the above and below, I hope you have a great Monday night wherever you’re spending it! Aloha for now…Glenn.
Here on Maui…it’s 540am Monday morning, skies are mostly clear over the island. The air temperature here in Kula, at my upcountry weather tower was 56.8 degrees, while it was 75 down at the Kahului airport, 70 out in Hana…with a 39 degree reading up at the summit of the Haleakala Crater at near the same time.
– We’re into the afternoon hours now, and we got our first shower of the day, which turned out to be quite heavy for a short period. Now at 210pm, here in Kula, the air temperature was 75.2 degrees, while it was 86 degrees down in Kahului, and over in Kapalua, with a cooler 82 out in Hana…and an even cooler 52 degrees atop the Haleakala Crater.
– It’s early evening, under partly to mostly cloudy skies, although some of our beaches have remained mostly sunny all day…especially along the north shore. Here in Kula, we had that one rather generous shower this afternoon, although the Ulupalakua area received much more than we did. The bulk of the showers over Maui and the rest of the state too, occurred over the leeward sides, and the nearby mountain slopes during the day.
World-wide tropical cyclone activity:

>>> Caribbean Sea: There are no active tropical cyclones
>>> Gulf of Mexico: There are no active tropical cyclones

1.) Showers and thunderstorms continue in association with a broad area of low pressure located about 600 miles south-southwest of the southern tip of the Baja California peninsula. Upper-level winds that have been inhibiting development are forecast to decrease and become more conducive for tropical cyclone formation during the next day or so. This system is expected to become a tropical depression by mid-week while it moves west-northwestward to northwestward at 10 to 15 mph.
When this system becomes a little more organized, and becomes a tropical depression, it will take on the title TD 07E…and if it strengthens into a tropical storm, it will take on the name TS Felicia. The models show it remaining offshore from the Mexican coast, taking a more or less west-northwesterly track.
Here’s a satellite image, along with the animated version…and what the hurricane models are showing
* Formation chance through 48 hours…high…80 percent
* Formation chance through 5 days…high…90 percent

A new study published in Global Change Biology, by researchers at the U.S. Geological Survey and the University of Wisconsin-Madison, assesses how global climate change will affect future malaria risk to native Hawaiian bird populations in the coming century.an.
Mosquito-carried diseases such as avian pox and avian malaria have been devastating native Hawaiian forest birds. A single mosquito bite can transfer malaria parasites to a susceptible bird, where the death rate may exceed 90 percent for some species. As a result, many already threatened or endangered native birds now only survive in disease-free refuges found in high-elevation forests where mosquito populations and malaria development are limited by colder temperatures. Unlike continental bird species, island birds cannot move northward in response to climate change or increased disease stressors, but must adapt or move to less hospitable habitats to survive.
“We knew that temperature had significant effects on mosquitoes and malaria, but we were surprised that rainfall also played an important role,” said USGS Wisconsin Cooperative Wildlife Research Unit scientist Michael Samuel. “Additional rainfall will favor mosquitoes as much as the temperature change.”
With warming temperatures, mosquitoes will move farther upslope and increase in number. The authors expect high-elevation areas to remain mosquito-free, but only until mid-century when mosquito-friendly temperatures will begin to appear at higher elevations. Future increases in rainfall will likely benefit the mosquitoes as well.
Scientists know that historically, malaria has caused bird extinctions, but changing climates could affect the bird-mosquito-disease system in unknown ways. “We wanted to figure out how climate change impacts birds in the future,” said Wei Liao, post-doctorate at University of Wisconsin-Madison and lead author of the article.
As more mosquitoes move up the mountainside, disease-free refuges will no longer provide a safe haven for the most vulnerable species. The rate of disease infection is likely to speed up as the numbers of mosquitoes increase and more diseased birds become hosts to the parasites, continuing the cycle of infection to healthy birds.
Researchers conclude that future global climate change will cause substantial decreases in the abundance and diversity of remaining Hawaiian bird communities. Without significant intervention many native Hawaiian species, like the scarlet ‘I‘iwi with its iconic curved bill, will suffer major population declines or extinction due to increasing risk from avian malaria during the 21st century.
There is hope for the birds. Because these effects are unlikely to appear before mid-century, natural resource managers have time to implement conservation strategies to protect these unique species from further decimation. Land managers could work toward preventing forest bird number declines by restoring and improving habitat for the birds, reducing mosquitoes on a large scale and controlling predators of forest birds.
