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. Here’s the Haleakala Crater webcam on Maui – if it’s working.

~~~ Hawaii Weather Narrative ~~~

Trade winds blowing through the first half of the new week…then lighter through Saturday. Here’s a weather chart showing a near 1019 millibar high pressure system located to the northeast of our islands…with a second larger near 1029 millibar high pressure cell to the north-northwest. At the same time, we see a low pressure system, with its associated trough over the ocean to the east of the state. More or less moderately strong trades will remain active through the middle of the new week. There’s a good chance that we will see the trades slow down thereafter, as a trough of low pressure gets in between our trade wind producing high pressure system…and the islands. These lighter trades will rebound by Sunday…into the following week.

Trade wind weather pattern will prevail, with just a few windward showers…generally dry leeward sides for the time being. Satellite imagery shows a minimum amount of lower level clouds to the north and east being carried our way on the trades, with a few patches offshore to the southwest. . Here’s the looping radar image, showing hardly any showers passing by over the offshore waters, with with even fewer along the windward sides of the islands.

Most areas around the state will find very typical summertime trade wind weather conditions prevailing through the first half of the new week. Looking further ahead, the remnant moisture from now retired tropical cyclone Cosme, which was active in the eastern Pacific, may bring an uptick in windward showers in the Thursday through Saturday time frame. At the same time, it should see an easing up in our trade wind speeds then too…stay tuned for more about these changes ahead. I’ll be back with more updates into the evening hours, I hope you have a great Sunday wherever you’re spending it! Aloha for now…Glenn.
