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

Very late summer…heading into very early autumn soon

Lots of clouds in our vicinity…with thunderstorms far southwest, south and southeast / we see what’s left of old tropical cyclone Orlene to our northeast…with its showery tail dragging behind it to the south and southeast

Partly cloudy…with cloudy areas in many areas

Increasing showers locally…mostly windward and mountains – Looping radar image

~~~ Hawaii Weather Narrative ~~~

Moderately strong trades…easing up some Thursday into the weekend. Here’s the latest weather map, showing moderately strong high pressure systems to our northwest and far northeast. At the same time, we have a low pressure trough east of the state. Our early autumn trade winds will ease up a touch or two through the weekend. The trade winds will then rebound early next week. This increase will occur thanks to an early season cold front, which will swing by to our north and away. As this frontal boundary, and a trough over us lose their influence, space will open up for the trade winds to become at least moderately strong…if not a bit stronger than that.

Here’s a wind profile…of the offshore waters around the islands – with a closer view

Low clouds with embedded showers carried by the wind, will affect us at times…mainly windward and mountain locations. Showers will also reach over into the leeward sections on the smaller islands at times. Speaking of showers, we’ll see an increase now into the weekend. The first part of this increase will be associated with the remnants of former tropical cyclone Orlene. Following in the wake of this first round of showers will be a trailing area of moisture Thursday into the weekend. Meanwhile, an early season cold front will approach the state Saturday, although won’t dip down into our area. Looking even further ahead, as we push into early next week, we’ll find improving conditions…although the windward biased showers will continue in an off and on manner.

Marine environment details: Winds and seas are expected to remain below the advisory threshold for the next few days. First the trough moving over the area from the east, and then the front approaching from the northwest, will keep the winds from getting too strong. Locally strong trade winds are expected to return early next week as a strong new high moves into position north of the area.

Surf will remain below the advisory thresholds on all shores. There will be a moderate south swell Thursday, and a small northwest swell is possible over the weekend.

 Autumn began this morning…with weather changes on the horizon

World-wide tropical cyclone activity…

>>> Atlantic Ocean:

Tropical Depression 12L (Karl) remains active, located approximately 525 miles south-southeast of Bermuda. Here’s the NHC graphical track map, a satellite image…and what the computer models are showing

Tropical Storm 13L (Lisa) remains active, located approximately 710 west-northwest of the Cabo Verde Islands. Here’s the NHC graphical track map, a satellite image…and what the computer models show

Here’s a satellite image of the Atlantic Ocean

>>> Caribbean: No active tropical cyclones

>>> Gulf of Mexico: No active tropical cyclones

>>> Eastern Pacific: No active tropical cyclones

1.) A large area of disturbed weather located about 850 miles south of the southern tip of the Baja California peninsula is associated with a broad area of low pressure. The associated shower and thunderstorm activity has increased since yesterday, and conditions appear favorable for a tropical depression to form during the next couple of days. This disturbance is forecast to move toward the northwest and then northward during the next several days.

Here’s a satellite image of this area, being referred to as Invest 94E…along with what the computer models are showing

* Formation chance through 48 hours…high…70 percent
* Formation chance through 5 days…high…90 percent

2.) Showers and thunderstorms associated with a weak area of low pressure located about 1200 miles east-southeast of the Big Island of Hawaii remain poorly organized. Any development of this system is expected to be slow to occur while it moves slowly westward during the next few days.

Here’s a satellite image of this area, being referred to as Invest 95E…along with what the computer models are showing

* Formation chance through 48 hours…low…10 percent
* Formation chance through 5 days…low…20 percent

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