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, Hawaii.

It’s mostly clear here in Maui County early this morning, although with some low clouds along the windward sides and some thin high cirrus as well. The low temperature at my place was a chilly 52.5 degrees…with a relative humidity of 78%.

For you full-on weather nerds out there, like me, here’s a great new blog by a friend of mine, Kevin Kodama, the former Senior Service Hydrologist at the NWSFO in Honolulu…Mauka Showers

Tropical Cyclone Kiko: I’m keeping a close eye on this hurricane, despite the fact that it’s still in the eastern Pacific. The Central Pacific Hurricane Center is suggesting that Kiko will cross into our Central Pacific this weekend. The latest GFS model has whatever is left of Kiko (definitely in a weakening mode) arriving here in the Hawaiian Islands early next week. Many changes in its path/intensity could occur between now and then. So, I will be keeping my eye on this hurricane each day going forward. You can follow along if you scroll down this page to the Tropical Cyclone section, and look for more information on Kiko.

 

Hawaii’s Broad Brush Weather Overview:  Light to moderate trade winds will bring a drier more stable air mass over the island chain through the remainder of the week. Light showers over windward and mountain locations can be expected in the overnight and early morning hours. Most leeward areas will be rather dry with sea breezes producing afternoon clouds and a few showers, especially on the Big Island.

Hawaii’s Weather Details: Radar and satellite show scattered showers moving across the state, with some low level clouds moving into the Big Island and Maui. A weak surface ridge parked north of Kauai will maintain light to moderate trades. An upper- level low northwest of the state will begin to creep northward, and in the process allow a strong mid- level ridge, to bring stable conditions to the entire state.

Most leeward areas will be rather dry, but sea breezes will produce afternoon clouds and a few showers, mainly on the Kona slopes of the Big Island. Windward and mountain showers will be possible overnight into the early morning hours. Little change is expected to the somewhat dry trade wind flow through the coming weekend.

With the latest National Hurricane Center update we now have Hurricane Kiko in the East Pacific basin. Hurricane Kiko is moving due west at 7 mph and should cross into the Central Pacific basin Saturday. It remains too early to tell what, if any, impacts this system might have on local weather as it nears the islands early next week.

Fire weather:  Dry conditions return with trade winds remaining in the light to moderate range, keeping the state below critical fire weather thresholds this week.

Hawaii’s Marine Environment:  A weak surface ridge to the north will remain nearly stationary and maintain moderate to locally fresh trade winds through the forecast period, with some localized sea breezes, especially across leeward waters.

Elevated surf will continue along north facing shores with a mix of a short to medium period north swell, and a small medium period northwest swell that has begun to fill in. These swells will peak today and gradually decline through Thursday. Reinforcing small short to medium period north-northwest swells are expected, keeping surf elevated through the end of the week.

Surf along south facing shores will continue to slowly decline as the current south swell fades. Background medium to long period energy will hold through the second part of the week, before a small to moderate long period south-southwest swell fills in over the weekend.

Below average surf is expected to continue along east facing shores, persisting through early next week.

Peak monthly high tides, combined with water levels running higher than predicted, may lead to minor flooding along the shoreline and in low-lying coastal areas Wednesday through the end of the week. Coastal Flooding will be mainly focused around the daily afternoon peak tide.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean: There are no active tropical cyclone

Eastern Tropical Atlantic

 >>> A tropical wave located over the far eastern tropical Atlantic south of the Cabo Verde islands is producing disorganized showers and thunderstorms. Environmental conditions appear conducive for gradual development of this system during the next several days, and a tropical depression is likely to form later this week or this weekend. This system is expected to move westward to west-northwestward at around 15 mph across the eastern and central tropical Atlantic through the weekend.

* Formation chance through 48 hours…low…30 percent
* Formation chance through 7 days…high…70 percent

 

Caribbean Sea:  There are no active tropical cyclone

Tropical cyclone formation is not expected during the next 7-days.

Gulf of America:  There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7-days.

 

Northeastern Pacific:

Tropical Cyclone Kiko…is located about 1815 east of Hilo, Hawaii

HURRICANE KIKO CONTINUES TO STRENGTHEN

According to the NHC advisory number 10

Kiko is moving toward the west near 6 mph and this motion is expected to continue through Wednesday. A gradual turn toward the west-northwest is expected late this week. Maximum sustained winds have increased to near 85 mph with higher gusts. Additional steady strengthening is expected during the next day or two, and Kiko could become a major hurricane by Wednesday night. Hurricane-force winds extend outward up to 15 miles from the center and tropical-storm-force winds extend outward up to 60 miles.

Tropical Cyclone 12E (Lorena)…is located about 240 west of Manzanillo, Mexico

TROPICAL DEPRESSION 12E BECOMES TROPICAL STORM LORENA

According to the NHC advisory number 3

Lorena is moving toward the northwest near 14 mph and this motion is expected to continue for the next few days before slowing and turning north then northeastward toward the latter portion of this week. Maximum sustained winds have increased to near 45 mph with higher gusts. Additional strengthening is forecast during the next 48 hours and Lorena could reach hurricane strength by Wednesday. Tropical-storm-force winds extend outward up to 35 miles from the center.

Interesting:  More Than 11,000 Workers Filed for Unemployment Assistance Programs Because of Los Angeles Wildfires, New Report Shows

Unemployment claims increased between 12% and 17% due to the January 2025 Palisades and Eaton fires, according to a new report from the nonpartisan California Policy Lab.

Analysis by researchers at the University of California institute showed that unemployment claims surged not only in the fire zones but also among people living in neighborhoods far from the fires, especially in South and Central Los Angeles. There were also large increases in claims from workers in low-wage industries like accommodations and food services, and workers with lower levels of education.

“Our analysis shows the economic impacts extended beyond the Palisades and Altadena, as workers who live in areas like South and Central L.A. but commuted to work in the fire areas also filed for unemployment in the aftermath of the fires,” explains report co-author Till von Wachter, faculty director of the California Policy Lab at UCLA and a professor of economics. “This report shows the critical role that unemployment insurance benefits can play in supporting people after natural disasters, and also provides insights that can be helpful for future disaster response planning and targeting relief to impacted people.”
