Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. These webcams are available during the daylight hours here in the islands, and at night whenever there’s a big moon shining down. Also, at night you will be able to see the stars, and the sunrise and sunset too…depending upon weather conditions.

~~~ Hawaii Weather Narrative ~~~

 

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

511am, clear early this morning…the low temperature here at my Kula weather tower was 51.5 degrees.

840am, clear sunny morning here in upper Kula Maui, with just some streaky high icy Cirrus clouds here and there. I just got back from my first walk of the day, which is the steepest. Here in Kula you’re either going uphill or downhill, not much level ground on the slopes of this leeward Haleakala Crater. I’ve mentioned it once before, although you might have missed it, I’m heading out on a vacation this coming Monday, flying to San Francisco, and on across the Golden Gate Bridge to my friend Linda’s in Corte Madera, Marin County.

 

Hawaii’s Broad Brush Weather Overview:  Light winds and mostly dry weather will prevail for the next couple of days. Strengthening trade winds from Friday into the weekend will bring an increase in showers, some potentially heavy, especially over windward areas.

Hawaii’s Weather Details: Light winds and mostly dry weather are on tap the next several days. Trade winds will strengthen from Friday into next week, and may bring an increase in showers, especially to windward areas.

Latest satellite imagery shows that there’s been a slight increase in low cloud cover over waters east of the islands, with areas of scattered low clouds punctuating otherwise nearly clear skies. A few small showers are noted over waters east of Maui and the Big Island, moving generally west near 10 mph. An area of showery low clouds that loitered near Kona airport through the night appears to be dissipating.

Land-based observations show light winds mostly blowing downslope and offshore, except at exposed windward locations, where light east trade winds are coming it at speeds less than 10 mph. The trade-wind-supporting ridge to the north, and the local pressure gradient, remains weakened by a slow-moving complex low about 1300 miles northwest of Kauai. The subtropical jet stream south of this feature is sending wispy high clouds over the area from the west, while morning soundings indicated a relatively dry air mass.

The slow-moving low to the northwest will keep winds light, while a quickly developing low about 1300 miles northeast of the islands will also contribute to keep the local pressure gradient loose into Friday. The resultant land and sea breeze weather regime means mostly clear (aside from some high clouds) and cool mornings, with a slight chance of a windward shower.

Afternoon clouds over leeward areas will also bring a chance of a shower, especially on the Big Island. A nearby ridge aloft will ensure little to no rainfall accumulation. As mentioned, there will be periods when increased high clouds move over the islands from the west, especially this afternoon and tonight.

High pressure building north of the islands from Friday into early next week, will lead to strengthening trade winds that become breezy by Sunday. The ridge aloft will weaken over the weekend, as a low aloft moves over the area from the north, but model guidance remains inconsistent as to the timing and location of this low.

A slow moving cold front will approach the islands from the northeast this weekend, and some guidance indicates that this source of increased low- and mid- level moisture will eventually move over the islands, with the increasing trade wind flow. The forecast has been indicating the potential for heavy showers (and even snow on the Big Island Summits) this weekend. Rainfall would favor windward areas with the trade winds prevailing.

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 surface ridge to the north will remain weak for the next several days, as broad low pressure meanders well northwest of the state. Expect land and sea breeze conditions near the coasts, with diurnally driven accelerations potentially leading to fresh breezes during the afternoons. A return of fresh to strong easterly trades is possible over the weekend, as the ridge strengthens to the north.

Surf along north and east-facing shores will trend up Wednesday through the second half of the week, as a north-northeast swell arrives from a storm-force low forecast to develop around 1,000 nautical miles to the northeast through mid-week. This will be a long-lived event, as the system slowly evolves and drifts northeastward late in the week. Guidance indicates a reinforcement from this system Friday into Saturday, which may coincide with the peak surf.

Heights will near advisory levels for east-facing shores from Thursday through Saturday, while north-facing exposures are expected to remain below advisory levels. For the long-range, guidance shows a gale- to storm-force low tracking eastward from the Bering Sea to the Gulf of Alaska late Wednesday through Friday. If this materializes, a northerly swell could arrive late Sunday into early next week from this feature.

Surf along south facing shores will remain small, with predominantly a mix of southeast and south to south-southwest swells. A slightly larger south swell is expected this weekend.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  There are no active tropical cyclones

Caribbean Sea:

Tropical Cyclone Oscar is located about 700 miles east-southeast of Long Island, Bahamas

OSCAR IS BARELY A TROPICAL CYCLONE

Oscar is moving toward the northeast near 12 mph, and a faster northeastward motion is expected during the next day or two. On the forecast track, the center of Oscar will be moving away from the Bahamas later today or tonight. Maximum sustained winds are near 40 mph with higher gusts. Oscar could dissipate later today, or merge with an extratropical low pressure system within the next couple of days. Tropical-storm-force winds extend outward up to 105 miles from the center.

Gulf of Mexico:  There are no active tropical cyclones

Northeastern Pacific: 

Tropical Cyclone Kristy is located about 405 miles southeast of Socorro Island

KRISTY COULD RAPIDLY STRENGTHEN OVER THE NEXT COUPLE OF DAYS

Kristy is moving toward the west near 16 mph and a continued westward motion is expected for the next several days. Maximum sustained winds are near 60 mph with higher gusts. Additional strengthening is forecast and Kristy could rapidly intensify into a major hurricane by the latter part of this week. Tropical-storm-force winds extend outward up to 70 miles from the center.

Interesting:  U.S. Winter Outlook: Warmer and Drier South, Wetter North

A slowly-developing La Nina is favored to influence conditions for the upcoming winter across most of the country, according to NOAA’s U.S. Winter Outlook released today by the Climate Prediction Center — a division of NOAA’s National Weather Service. This outlook is for December 2024 through February 2025 and contains information on likely conditions throughout the country for temperature, precipitation and drought.

This winter, NOAA predicts wetter-than-average conditions for the entire northern tier of the continental U.S., particularly in the Pacific Northwest and the Great Lakes region, along with northern and western Alaska. Meanwhile, drier-than-average conditions are expected from the Four Corners region of the Southwest to the Southeast, Gulf Coast and lower mid-Atlantic states.

“In September, we announced a $100 million investment into NOAA’s high-performance computer system to advance research on weather, climate and ocean predictions because understanding our climate system is essential for making longer-term predictions like the Winter Seasonal Outlook, which provides vital information for many of our partners and the public,” said Michael Morgan, Ph.D., NOAA’s assistant secretary of commerce for observation and prediction. “We continue to innovate in this space, developing new ways to share winter forecast information with the public.”
