Precipitation Totals – The following numbers represent the largest precipitation totals (inches) during the last 24 hours on each of the major islands, as of Monday morning:

0.34 PAHOA, BIG ISLAND
Weather Chart – Here’s the latest (automatically updated) weather map…showing a 1032 millibar high pressure system located far NE of Hawaii now…too far away to provide the strong trade winds closer to the high’s center. This high pressure system has a ridge of high pressure extending SW to the north of Hawaii. This pressure configuration will keep light to moderately strong trade winds blowing both Monday and Tuesday…somewhat stronger in those locally windiest areas during the afternoons. 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.
Tropical Cyclone activity in the eastern and central Pacific – Here’s the latest 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. Here’s a tracking map covering both the eastern and central Pacific Ocean.
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.

The trade winds will remain active through the next week, blowing in the light to moderately strong range here in the islands. The latest weather map shows a strong 1034 millibar high pressure system located far to the NE of the islands…the source of our trade winds now. This high pressure system is too far away to provide us with its strongest winds. It associated ridge is close enough however, to keep light to moderately strong trade winds across our tropical latitudes. The current computer forecast models suggest that we will see no end to this late summer trade wind episode through at least the next week.
An upper level low pressure system, southwest of Oahu, will keep our local atmosphere a bit unstable, with some of the showers around briefly heavy. As this satellite image shows, there is a distinct lack of clouds being carried our way on the trade winds. Although that satellite picture does show an area of clouds just east of the state, which should increase our clouds and a few showers Sunday night into Monday morning. The daytime heating of the islands may prompt some afternoon cloud buildups as well, which may provide a shower or two. We can’t rule out the chance of a few heavy showers as a result…since the upper low pressure in our general vicinity will allow good vertical development to these afternoon convective clouds.
It’s Sunday evening here in the islands, as I update this last paragraph of today’s narrative. The upper level low pressure system mentioned above, is still around, now located to the SW of Oahu. This upper low is expected to pass across our islands, and end to the north of Hawaii over the next couple of days. Sometimes this can promote showers, or even locally heavy showers, although the models show not very much moisture for this upper low to work with…so there’s a good chance that it won’t have much influence on our local weather conditions. ~~~ A storm far to the NW has generated a NW swell, which will arrive around the middle of the new work week ahead. Speaking of surf, a storm in the southern hemisphere, down near New Zealand, has also generated a swell, which will arrive on the oppose sides of our islands (along the leeward shores) about the same time during the new week ahead. ~~~ I’ll be back early Monday morning with your next weather narrative, I hope you have a great Sunday night wherever you happen to be spending it! Aloha for now…Glenn.
