Marine Winds – Here’s the latest (automatically updated) weather map showing a weak 1019 millibar high pressure system just to the northwest of our islands. Our local trade winds will be lighter both Tuesday and Wednesday.
Satellite and Radar Images: To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with this Infrared Satellite Image of the islands to see all the clouds around during the day and night. This next image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible image. Finally, here's a Looping IR satellite image, making viewable the clouds around the islands 24 hours a day. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image.
Hawaii’s Mountains – Here’s a link to the live web cam on the summit of near 13,500 foot Mauna Kea on the Big Island of Hawaii. The tallest peak on the island of Maui is the Haleakala Crater, which is near 10,000 feet in elevation. These two web cams are 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.
Tropical Cyclone activity in the eastern and central Pacific – Here’s the latest weather information coming out of the National Hurricane Center, covering the eastern north Pacific. You can find the latest tropical cyclone information for the central north Pacific (where Hawaii is located) by clicking on this link to the Central Pacific Hurricane Center. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast…can be found here. Here's a tropical cyclone tracking map for the eastern and central Pacific.
Aloha Paragraphs
Lighter winds…afternoon showers locally
The trade winds become considerably lighter now…through much of this work week. Glancing at this weather map, we find a weak high pressure system to the northwest of our islands. The forecast continues to suggest that our trade winds will remain quite light for the next 5-6 days. Look for rebounding trade winds towards the latter part of the weekend.
Our winds will remain lighter now…the following numbers represent the strongest gusts (mph), along with directions Monday evening:
09 Lihue, Kauai – NE
17 Kahuku, Oahu – ENE
17 Molokai – ENE
13 Kahoolawe – NE
15 Kahului, Maui – NE
05 Lanai – NW
18 Upolu Point, Big Island – NE
We can use the following links to see what’s going on in our area of the north central Pacific Ocean Monday night. Looking at this NOAA satellite picture we find clouds over the mountains, and offshore to the northeast and southwest. We can use this looping satellite image to see areas of thunderstorms over the ocean, far to the south through southwest of the islands. Checking out this looping radar image we see that there are just a few showers being carried along in the trade wind flow…especially over the ocean southwest of Oahu.
Sunset Commentary: The trade winds began their easing in strength today, which will continue through most of the rest of this week. There’s been a few showers around during the last 24 hours, although nothing remarkable. The main thing this week will be the lighter wind flow…which is the first sign of the upcoming fall season that we've seen here in the tropics. There will be a reduction in speeds starting today, which will carry forth through much of the week.
These lighter trade winds will cut into our trade wind weather pattern, putting us into a modified convective weather pattern. There may still be a few windward showers during the nights. As the winds will be lighter however, we'll see clouds gathering around the mountains during the second half of the day, leading to afternoon upcountry showers along our leeward slopes here and there. The nights will clear out again, with slightly cooler than normal early morning hours.
Here in Kula, Maui at 5pm HST Monday evening, skies were mostly cloudy, with an air temperature of 68.7F degrees. It clouded up early today, with a few light showers here in Kula, and down in Ulupalakua too. This evening I saw a pretty heavy looking shower between here and Kihei, which was an interesting weather feature. At any rate, the daytime clouds will clear out after dark, with the early mornings, even at sea level, becoming cooler than we've seen for most of the summer. I was mentioning above that this week's weather will represent the first sign of our upcoming autumn season. A deep storm low pressure system is evident in the Gulf of Alaska now, which is sending out several cold fronts southward. Here's a weather map to see these weather features. This early season storm has hurricane force winds revolving around the eastern side of its center. None of these fronts will be able to reach our islands, although one will actually get rather close this week. This is why our winds will be lighter. I find this very interesting from a weather perspective! The latest computer forecast models are now showing that the trade winds may not return until next Monday. ~~~ I'll be back early Tuesday morning with your next new weather narrative, I hope you have a good Monday night until then! Aloha for now…Glenn.
