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.

Aloha Paragraphs

We see considerable thunderstorms in the deeper tropics…
along with tropical Depression 08E well to our east-southeast

Thunderstorms remain offshore to the
south of the islands…light high clouds
moving over Kauai from the west
Looping version

Clear to partly cloudy over the islands – Looping version

Some showers over the islands – looping radar image

High Surf Advisory…large surf along our south
and west shores – through this evening

~~~ Hawaii Weather Narrative ~~~

The trade winds will remain softer than normal…then gradually increase in strength later Tuesday onwards. 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 two near 1030 millibar high pressure systems to the northwest and northeast of the state. At the same time, we have troughs of low pressure to the west and east…which are helping to keep the trades on the lighter side of normal here in Hawaii. The trade winds are expected to gradually increase into mid-week onwards into Saturday. We may see another increase in trade wind speeds Sunday into next Monday…as what will probably be tropical depression, or former tropical depression 08E moves by just south of the state then.

We’re involved in a modified convective weather pattern, with afternoon clouds collecting over and around the mountains…with some upcountry showers. These lighter winds and somewhat higher than normal humidity levels, kept a sultry reality in place again today. As the trade winds pick up later tomorrow onwards, we’ll see the focus of showers returning to our windward sides. There are no pronounced areas of wet weather on the horizon, at least towards the east and northeast, that the trade winds would carry to our windward sides. The next likely wetter than normal episode might arrive later this coming weekend into early next week. A tropical system will be moving close to the state then, and the northern fringe of this tropical moisture may spread over some parts of the island chain then…stay tuned.

The deeper tropics are active with thunderstorms all the way towards Mexico…more than the normal amounts in fact. I’ll be watching this elongated zone well to Hawaii’s south, southeast, and east-southeast. There’s the chance a tropical system, with its associated moisture, may migrate in our general direction late this coming weekend. This area has become Tropical Depression 08E…and when it likely strengthens, briefly into a tropical storm…it will take on the name Guillermo. Here’s a satellite image of its location, the looping version, and finally what the computer models are showing. At this point, it appears that whatever is left of what will then likely be post-tropical cyclone 08E, may pass south of the Aloha State in the Sunday into next Monday time frame – more information below. 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 545am Monday morning, skies are mostly clear, although there are areas of low clouds along the windward coasts and slopes. The air temperature here in Kula, at my upcountry weather tower was 58.6 degrees, while it was 76 down at the Kahului airport, 75 out in Hana, and 46 degrees up at the summit of the Haleakala Crater at about the same time. / Now at 1050am, clouds have gathered around the mountains, and it’s mostly cloudy overhead here in Kula. The beaches are still clear to partly cloudy, with quickly warming temperatures.

– It’s now 1215pm, and the clouds have been getting darker and darker for the last hour or so. I just heard from a friend in Pukalani, and she said it was raining down there. Here in Kula, it just started to lightly sprinkle, although I think these clouds have more to give! / It’s now 410pm, and yes indeed, there have been several showers, quite light in general.

– We’re into the early evening now, at 605pm, under partly cloudy skies in general. Here at my place in Kula, it was cool, foggy, and still lightly misting. It’s 69.9 degrees here at my weather tower, while at the same time, down at the Kahului AP, it was a much warmer 86 degrees in contrast.

World-wide tropical cyclone activity:

>>> Atlantic Ocean: There are no active tropical cyclones

>>> Caribbean Sea: There are no active tropical cyclones

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

Here’s a satellite image of the Atlantic Ocean

Here’s a satellite image of the Caribbean Sea…and the Gulf of Mexico

Tropical cyclone formation is not expected during the next 5 days over the Gulf of Mexico, Caribbean Sea or Atlantic Ocean

Here’s the link to the National Hurricane Center (NHC)

>>> Eastern Pacific: 

Tropical Depression 08E remains active, and is located about 1325 miles west-southwest of the southern tip of Baja California. TD 03E will likely strengthen a bit more, and if so…take on the name Guillermo later today, here’s a NHC graphical track map, along with a satellite image…and what the hurricane models are showing.

1.)   A broad low pressure system located about 1150 miles south- southwest of the southern tip of the Baja California peninsula continues to produce a large area of disorganized showers and thunderstorms. Environmental conditions are expected to be generally conducive for development, and this system is likely to become a tropical depression by this weekend while it moves westward at about 15 mph.

* Formation chance through 48 hours…low…10 percent
* Formation chance through 5 days…high…80 percent

Here’s a wide satellite image that covers the entire area between Mexico, out through the central Pacific…to the International Dateline.

Here’s the link to the National Hurricane Center (NHC)

>>> Central Pacific: There are no active tropical cyclones

1.)  The National Hurricane Center in Miami, Florida is issuing advisories on tropical depression Eight-E, located approximately 1775 miles east-southeast of Hilo, Hawaii. Tropical depression Eight-E is currently moving west northwest at 13 mph, and is not expected to cross 140°W longitude into the Central Pacific Hurricane Center area of responsibility before Wednesday night.
