~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Saturday comments:  I’m home here in upper Kula, Maui, I hope you have a great Friday wherever you happen to be spending it.

456am, quite cloudy early this morning…the low temperature here at my Kula weather tower was 56 degrees.

836am, I’m hearing from friends who live in Haiku, over on the windward side of east Maui, that it has been wet…very wet over night into this morning. It’s still cloudy here in upper Kula, although still dry.

919am, just started to sprinkle here at my place in Kula.

 

Hawaii’s Broad Brush Weather Overview:  Periods of heavy rainfall will continue and persist into Sunday, with isolated thunderstorms possible across the entire state. A Flood Watch remains in effect for all islands through Sunday afternoon. Drier, more typical breezy trade wind conditions are expected beginning on Monday through much of next week.

Hawaii’s Weather Details:  Deep moisture continues to move over the islands, which has prompted moderate to occasionally very heavy rain. The heaviest rain fell this morning over central and eastern Oahu, as well as eastern Maui. However, during the afternoon, nuisance flooding has continued to be a concern across all major Hawaiian Islands.

Latest satellite and radar trends show that recent rainfall rates have been trending down across the smaller islands, though the opposite is true for the Big Island, where rainfall has become more widespread. There remains plenty of moisture, instability, and large scale lift over the state, and a Flood Watch remains in effect until 6pm Sunday for all Hawaiian Islands.

For tonight, hi-res guidance, as well as the GFS model, are hinting at the possibility of a surge of trade winds moving across the islands from north to south. Meanwhile, ample moisture will remain in place, and will be further enhanced as an upper level trough deepens into a low and moves closer to the state.

Atmospheric instability will increase as this upper level feature moves closer, and will maintain the possibility for deeper convection and isolated thunderstorms. With all of these ingredients in play, any slow-moving heavy showers or thunderstorms will continue to produce flooding concerns.

On Sunday, trades will become locally breezy as the front north of the islands dissipates, and ridging begins to build. The upper level low will move more directly overhead, providing increasingly unstable conditions aloft. With plenty of low to mid-level moisture still streaming across the state, it won’t take much to kick off moderate to locally heavy showers over already saturated ground.

With the strengthening trades, showers will likely transition to focus mainly over windward areas. However, showers will also still form in the more sheltered leeward areas, particularly over the Kona slopes of the Big Island where locally heavy rain could fall into Sunday afternoon.

As the upper low pushes west of the area and surface ridging builds to the north, a breezy and increasingly stable trade wind flow is expected for much of next week, beginning on Monday. Pockets of moisture riding in on the trades will provide occasional brief increases in windward showers throughout the week.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Hawaii’s Marine Environment:  A frontal system to the north of the islands continues to maintain light to moderate winds over the area. As the front continues weaken, expect moderate to locally strong trades to build back in due to a ridge to our north. The trades should continue to strengthen into the first half of the new week, with widespread strong trades possible by mid-week. Small Craft Advisories for the typical windy waters around Maui County and the Big Island are possible Sunday.

A mid to upper level disturbance to the northeast of the islands combined with abundant moisture moving over the region from the east, will continue the chance for thunderstorms in both the coastal and offshore waters. While the chance for thunderstorms over the coastal will diminish by Sunday, the offshore waters will have the chance into mid-week.

The nearshore buoys exposed to the north-northeast swell peaked, with the swell now on the decline. Surf along east facing shores is expected to fall below advisory levels. However, the combination of strengthening trades and a small east swell from Tropical Cyclone Kristy should continue to produce rough and elevated surf along east facing shores throughout the new week.

After a few days of strong trades, surf could build to advisory thresholds along east facing shores by the middle of the new week. Another small to moderate north swell should fill in on Sunday and peak on Monday, then gradually decline. A new south swell is expected to peak, and then slowly decline into the early part of the new week.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:  There are no active tropical cyclones

>>> Southwestern Caribbean Sea:

A broad area of low pressure is likely to develop over the southwestern Caribbean Sea around the middle part of this week. Some gradual development of this system is possible through the end of the week as it begins to drift northward or northeastward over the southwestern Caribbean Sea.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…30 percent

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific: 

Tropical Cyclone Kristy is located about 1255 miles west of the southern tip of Baja CA

KRISTY QUICKLY UNRAVELING…FORECAST TO DEGENERATE INTO A REMNANT LOW ON SUNDAY

Kristy is moving toward the north-northwest near 12 mph. A turn toward the northwest and west at a slower forward speed is expected tonight and on Sunday. Maximum sustained winds have decreased to near 60 mph with higher gusts. Additional weakening is forecast, and Kristy is expected to degenerate into a remnant low on Sunday. The remnant low will likely dissipate by early Monday. Tropical-storm-force winds extend outward up to 140 miles from the center.

>>> Western East Pacific:

An area of low pressure is forming within a large area of disorganized showers and thunderstorms located well to the southwest of the southwestern tip of the Baja California peninsula. Environmental conditions appear conducive for additional development of this system, and a tropical depression is likely to form by the early to middle part of the upcoming week while moving westward or west-northwestward at about 15 mph over the far western portion of the eastern Pacific basin. This system is expected to move into the central Pacific basin on Wednesday or Thursday.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…high…80 percent

Interesting:  Fire Speed, Not Size, Drives Threat to People, Infrastructure

Fast-growing fires were responsible for nearly 90 percent of fire-related damages despite being relatively rare in the United States between 2001-2020, according to a new CU Boulder-led study. “Fast fires,” which thrust embers into the air ahead of rapidly advancing flames, can ignite homes before emergency responders are able to intervene. The work, published today in Science, shows these fires are getting faster in the Western U.S., increasing the risk for millions of people.

The research highlights a critical gap in hazard preparedness across the U.S. — National-level fire risk assessments do not account for fire speed or provide insight into how people and communities can better prepare for rapid fire growth events.

“We hear a lot about megafires because of their size, but if we want to protect our homes and communities, we really need to appreciate and prepare for how fast fires move,” said Jennifer Balch, CIRES fellow, associate professor of Geography, and the lead author of the study. “Speed matters more for keeping people safe.”
