Weather Chart – Here’s the latest (automatically updated) weather map…showing a dissipating cold front over Maui Thursday. At the same time, we find high pressure systems far to the NW and NE. As the cold front falls apart, our winds will gradually swing around to the NE, providing trade winds with a bit more of a northernly aspect than usual through Friday. Here’s a Weather Map Symbol page for clarification about what all those weather symbols mean on the map.
Hawaii’s Mountains – Here’s a link to the live webcam on the summit of near 14,000 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 webcams are available during the daylight hours here in the islands…and when there’s a big moon rising just after sunset for an hour or two! Plus, during the nights and early mornings you will be able to see stars, and the sunrise too…depending upon cloud conditions.
Satellite Images – To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with the Infrared Satellite Image of the islands to see all the clouds around the state 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. This next image shows a larger view of the Pacific…giving perspective to the wider ranging cloud patterns in the Pacific Ocean…out from the islands. To help you keep track of where any showers may be around the islands, here’s the latest animated radar image.
Tropical Cyclone Activity – The eastern Pacific hurricane season runs from May 15 through November 30…while the central Pacific (where Hawaii is) runs from June 1 through November 30. The latest storm information for the eastern Pacific can be found by clicking here. A storm tracking map for both the central and eastern areas can be found by clicking here. For the central Pacific, the latest storm information can be found by clicking here.

A shower bearing cold front is moving down through the Hawaiian Islands Wednesday. This cloud band moved over the Garden Isle of Kauai early Wednesday morning, and past Oahu by noon. Showers hadn’t been generally heavy, although there was a 2.72 inch report at the Kokee gauge, up in the mountains of Kauai. The expectation is for this dissipating front to bring some lesser amount of showers to the islands of Maui County during the evening hours…with even lighter amounts for the Big Island Wednesday night. The majority of the associated showers will dampen the windward sides, while the leeward areas may not see much, if any, showers.
Perhaps more interesting than the front’s minor showers, will be the chilly north to NNE breezes that push in behind the cloud band. An air flow from this direction brings dry and cool air into the Aloha state…although the north facing slopes will likely remain misty for a while after the front goes through on Thursday. Daytime temperatures will be slightly chilly for a couple of days, with folks reaching for that extra blanket at night. Thereafter, the breezes will shift gradually to the NE, which will continue to bring slightly cooler air than usual into our area…with still a few windward showers falling.
The latest computer model output suggests that we may see another increase in showers this weekend. An upper level low pressure system is forecast to edge in our direction from the west…enhancing shower production from whatever clouds that may be around. One of the models, the GFS, shows a slug of moisture riding up from the deeper tropics, just to the east of the Big Island. At the same time, there may be the leftover moisture lurking out to the east and NE, from the cold front that’s moving through the islands now. The long and short of all this is that the Big Island may see fairly generous rainfall amounts, which could sneak over other parts of the state as well. Next week looks like the trade winds may filter back into the state, but that’s too far out to know for sure yet.
It’s early Wednesday evening here in Kula, Maui, as I begin writing this post sunset commentary. As I was driving home from work in Kihei, I was delighted by a fantastic sunset as I got up into the Kula pasturelands! All day there had been a swath of high clouds overhead, carried by the jet stream, right over Maui. It lit up so beautifully, it was ever so briefly spectacular. Here’s a satellite image so that you can track the progress of this frontal boundary noted above, as it slides down through Maui and on to the Big Island. While we’re looking at such things, here’s a looping radar image, so you can see where the showers are falling now too. Thursday will find sunny skies along the leeward sides, that is if the high cirrus clouds depart our area. As we move into Friday, we should see more decent weather prevailing, with still that chance that we could see another dose of showers arriving this weekend…more on that in Thursday morning’s narrative. I hope you have a nice Wednesday night! Aloha for now…Glenn.
