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

An area of disturbed weather to our south…
with an early season cold front north

Here’s a wind profile…of the area around the islands –
with a closer view of Hawaii

Thunderstorms well offshore to the south

A mix of clear to partly…to mostly cloudy skies,
showers lined up to our northeast from Oahu
down through Maui County and the Big Island

There are showers…mostly along the windward sides

High Surf Advisory…east shores of Kauai, Oahu,
Molokai, Maui and the Big Island

Small Craft wind Advisory…windiest coasts and
channels across the state

~~~ Hawaii Weather Narrative ~~~

Strong and gusty trade winds will remain over the islands…easing up a little Wednesday into Friday. Here’s the latest weather map, showing the Hawaiian Islands, and the rest of the North Pacific Ocean, along with a wind profiler of the central Pacific. We find high pressure systems to the north and northeast of the state. At the same time, we find tropical low pressure systems stretched out southwest through southeast of the state. Finally, there’s a storm with hurricane force winds to our north-northeast…with its associated cold front well north of Hawaii. Our winds are arriving from the trade wind direction, and will continue to do so this week. There’s a chance that stronger winds may arrive this weekend into early next week…stay tuned.

We’ll find showers along our windward sides…extending over into the leeward sides locally. The windward sides will receive most of the incoming showers, although they should gradually become less active over the next couple of days. The models show the return to a more normal trade wind weather pattern into Friday. There’s a chance that a couple of tropical weather systems could develop to our southwest this weekend into early next week, and move up towards the islands. Whether this occurs or not, the models are showing a possible rich stream of tropical moisture taking aim on the Aloha State towards the weekend…stay tuned.

Unsettled weather may arrive this weekend…with possible widespread heavy rains and gusty winds. The models are pointing out an unusual weather situation that could develop this weekend into the first part of next week. A very wet flow of moisture may arrive over the state from the deeper tropics to our southwest. Some of the models are showing one or more tropical systems moving up near the islands this weekend into next week as well. The models have been pointing out this situation for several days now, although the exact details remain unclear at the moment. It would be wise to pay close attention to this rather drastic change in weather…as we move into the weekend time frame.

Here on Maui…It’s 530am Wednesday morning…with clear to partly cloudy skies.

– It’s mid-afternoon, under partly to mostly cloudy skies, although with some clear sunny spots too.

– Early evening clouds are rather predominate, with showers falling along the windward sides…even a few sprinkles here in Kula before sunset.

I’ll be back with many more updates on all of the above and below, I hope you have a great Wednesday night wherever you’re spending it! Aloha for now…Glenn.

World-wide tropical cyclone activity:

>>> Atlantic Ocean:

Hurricane 11L (Joaquin) remains active, located 80 miles south-southeast of San Salvador, with sustained winds of 125 mph (major category 3 hurricane). Here’s the NHC graphical track map, along with a satellite image of this system…and what the computer models are showing

1.)  A non-tropical area of low pressure centered over the central Atlantic about 700 miles southeast of Bermuda is producing a large area of cloudiness and thunderstorms. Environmental conditions are expected to be conducive for the low to gradually obtain more tropical characteristics, and a tropical depression is likely to form in within a few days while the low moves slowly north-northwestward to northward.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 5 days…high…80 percent

Here’s a satellite image of the Atlantic Ocean

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

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

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

>>> Eastern Pacific:

Post-Tropical Cyclone 17E (Marty) is dissipating, located 160 miles south of Manzanillo, Mexico, with sustained winds of 30 mph. Here’s the NHC graphical track map, along with a satellite image of this system – Final Advisory

1.)   There has been little change with the organization of a broad area of low pressure located a little more than 1000 miles southwest of the southern tip of the Baja California peninsula. Environmental conditions are gradually becoming more conducive for development, and a tropical depression is likely to form during the next couple of days while the low moves slowly westward.

* Formation chance through 48 hours…high 70 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.

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

1.)  An area of disturbed weather about 550 miles south-southeast of Honolulu is nearly stationary. Thunderstorms in this area remain disorganized.

* Formation chance through 48 hours, low…10 percent

2.) An area of disturbed weather about 1000 miles west-southwest of Honolulu is nearly stationary. Thunderstorms in this area are disorganized.

* Formation chance through 48 hours, low…10 percent
