Hawaii’s MountainsHere’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.

Aloha Paragraphs

Our trade winds will continue blowing well into the future

Heavy rain may fall locally, with potential flooding…
improving weather into Wednesday

~~~ Hawaii Weather Narrative ~~~

Our trade winds will remain active…blowing generally in the moderately strong range. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a real-time wind profile of the central Pacific…focused on the Hawaiian Islands. We have a moderately strong high pressure system located to the north of the state. At the same time, we have a surface trough of low pressure moving away to our west. The forecast calls for the trade winds to remain active through the upcoming week. 

Satellite imagery shows a mix of high, middle, and low level clouds…along with thunderstorms over the ocean to the north of Kauai. Looking at this larger looping satellite image, it shows blossoming thunderstorms over the ocean to the northwest of Kauai, and high clouds streaming overhead on the Big Island from the southwest. Here’s the looping radar, showing passing showers moving across our area, most of which are light to moderately heavy at the moment, falling along the windward sides.  An upper level low pressure system, located to the west and northwest of the state, in conjunction with abundant atmospheric moisture over the state…will keep the threat of heavy rains active.

We’re approaching the tail-end of this unusually wet period…with improved weather expected Tuesday through Saturday.  The best chance for more heavy rains today will be focused over the Kauai end of the chain. Although, showers or even a thunderstorms will keep the threat of localized flooding over all the islands for the time being. The ingredients for more rain, including an unstable atmosphere and abundant moisture…remain in place on this first day of the new work week. It will take until Tuesday or so before these inclement weather conditions move to the west of Hawaii, allowing a more typical trade wind weather pattern to return. Please remain diligent in your safe driving practices, as dangerous flooding conditions may exist in places. Finally, the models continue showing another round of tropical showers arriving later this coming weekend, into early next week…although most of it will likely pass by south of Hawaii. It should be noted however, that this next weekend rainfall event won’t be anything like what we’ve seen the last few days! Aloha for now…Glenn.

World-wide tropical cyclone activity:

North Eastern Pacific:
There are no active tropical cyclones

1.) Disorganized showers and thunderstorms have decreased this morning in association with an area of low pressure located several hundred miles south-southwest of Manzanillo, Mexico. Development, if any, of this system should be slow to occur during the next day or so as it moves westward or west-northwestward at around 15 mph.

* Formation chance through 48 hours…low…10 percent.
* Formation chance through 5 days…low…10 percent.

2.)  Area of low pressure is expected to form well south of the coast of Mexico later this week. Some development of this system is possible by this weekend as it moves generally westward to west-northwestward.

* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 5 days…low…20 percent.

Interesting: Devil Rays are deep divers!- Thought to dwell mostly near the ocean’s surface, Chilean devil rays (Mobula tarapacana) are most often seen gliding through shallow, warm waters. But a new study by scientists at Woods Hole Oceanographic Institution (WHOI) and international colleagues reveals that these large and majestic creatures are actually among the deepest-diving ocean animals.

“So little is known about these rays,” said Simon Thorrold, a biologist at WHOI and one of the authors of the paper, published July 1, 2014, in the journal Nature Communications. “We thought they probably traveled long distances horizontally, but we had no idea that they were diving so deep. That was truly a surprise.”

Researchers utilized pop-up satellite archival transmitting tags to record the movement patterns of 15 Chilean devil rays in the central North Atlantic Ocean during 2011 and 2012. The tags, which stay on the animals for up to 9 months, also measure water temperature, depth, and light levels of the waters. Once the tags pop off, they float to the surface and beam data via the ARGO satellite system back to computers on shore.

“Data from the tags gives us a three-dimensional view of the movements of these animals, and a window into how they’re living in their ocean habitat—where they go, when, and why,” Thorrold added.

Devil rays, which can grow as large as 13 feet across, are ocean nomads traveling large areas of the ocean. Dive data from the tags showed individuals also routinely descended at speeds up to 13.4 miles per hour to depths of almost 2,000 meters (1.24 miles) in water temperatures less than 39.2 degrees Fahrenheit.

The deep dives generally followed two distinct patterns. The most common involved descent to the maximum depth followed by a slower, stepwise return to the surface with a total dive time of 60 to 90 minutes. The tagged rays generally only made one such dive during a 24-hour period. In the second dive pattern, individuals descended and then remained at depths of up to 3,280 feet for as long as 11 hours.

Chilean devil rays (Mobula tarapacana) are actually among the deepest-diving ocean animals.
