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.

We can use the following links to see what’s going on in our area of the north central Pacific Ocean. Here’s the latest NOAA satellite picture – the latest looping satellite image… and finally the latest looping radar image for the Hawaiian Islands.

~~~ Hawaii Weather Narrative ~~~

Trade winds becoming slightly lighter as we push through this week. Here’s a weather chart showing a near 1025 millibar high pressure system located to the northwest of our islands, with an associated ridge of high pressure running eastward…to the north of the islands. At the same time, we find an old frontal cloud band, called a shearline to our north, which is moving southward towards our islands. Our trade winds will remain active…although easing some today through the next several days.

Trade wind weather pattern will prevail, with windward showers. Satellite imagery shows minor areas of high and middle level clouds to the northwest through north and northeast of the state. Here’s the looping radar image, showing quite a few showers passing by along our windward coasts and slopes, and over the offshore waters as well…most notably over Maui County and Oahu at the time of this writing.

This old cold front will drop down over the state by later Thursday into Friday…which will increase our windward showers again.  This out of season band of clouds will reach Kauai and Oahu first, and then may be pushed down across the rest of the state. This moisture will influence the windward coasts and slopes primarily, with perhaps a few showers reaching over into the leeward sides on the smaller islands…some of which may become quite generous. As we get into the upcoming weekend, our showers will back off again, bringing favorably inclined trade wind weather conditions…into the first part of next week. Speaking of next week, we may see some residual showers from current hurricane Cosme, which will be long retired by then. I’ll be back with more updates on all of the above during the day, I hope you have a great Tuesday wherever you’re spending it!  Aloha for now…Glenn.
