Weather Chart Here’s the latest (automatically updated) weather map…showing a trough of low pressure to our east, and a ridge of high pressure to our NW. This pressure configuration will cause NE winds to blow today. As the trough moves westward over the state, our winds will become lighter, eventually becoming easterly as the trough moves to the west of the islands. Here’s a Weather Map Symbol page for clarification about what all those funny weather symbols mean.

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 only available during the daylight hours here in the islands…that is unless there’s a big moon rising just after sunset for an hour or two!

Satellite Images — To view the cloud conditions we have here in Hawaii, please use the following satellite links, starting off with the Infrared Satellite Imageof the islands to see all the clouds around the state. This next satellite image is one that gives close images of the islands only during the daytime hours, and is referred to as a Close-up visible satellite image. The next satellite 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 radar image.

Aloha Paragraphs

 

A trough of low pressure aloft and at the surface during the last 24 hours, has kept our atmosphere relatively unstable. This instability caused showers to form over and around the islands, some of which were locally quite heavy. There weren’t any intense showers though, with no reports of flooding on any of the islands…although the Big Island will likely see the most showers around Monday. The low pressure system is moving away towards the east, with the rest of the state from Maui westward finding improving weather.


As these troughs move away, our weather will settle down for the time being, at least in most areas.
At the same time, weather maps show a high pressure ridge to the NW of Hawaii. The orientation of these low and high pressure systems, will bring cool NE trade winds back into the state through Tuesday. This wind alignment will keep some clouds and showers passing over the windward sides of the islands. The leeward sections will see more sunshine, with just a few showers on the smaller islands.


The weather outlook remains somewhat complex, with a degree of uncertainty involved with this weeks forecast.
The latest computer forecast model output shows the trough to our east, retrograding back westward, to near the islands around mid-week. This would bring back the threat of showers to our area Wednesday and Thursday. Those same models go on to show a Kona low pressure system forming towards the weekend. Depending upon where this low forms will help determine where any associated rain would fall…still a bit too early to know quite yet.


Weather conditions during the winter month of February can change more dynamically than during the summer months.
Thus, the uncertainty surrounding the exact weather conditions this week. There’s a decent chance that we could get some more rainfall at some point, although it’s not totally clear when. Perhaps the best chances, from this vantage point, would be Wednesday and Thursday, and then again this coming weekend. Things may change, so we need to remain a bit more flexible than usual, as these possibilities sort themselves out.

It’s early Tuesday morning here in Kula, Maui. I just got through composing 45 minutes of new weather narrative material, which I was trying to copy and paste into this space. However, the battery on my laptop went dead just at that moment…and I lost it all! I couldn’t believe that happened, and now have yesterday’s information above. I’m sorry about this! I’ll try and find some time to write out something a little later this morning, please check back then. By the way, Happy Valentines Day! Aloha for now…Glenn.
