~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Monday comments:  I’m at home here in upper Kula, Maui, Hawaii

540am, it’s totally clear here at my place, with the low temperature 56 degrees, relative humidity is 77%…with near calm conditions

911am, it’s just about as cloudless as it ever gets here in Maui County!

110pm, mostly sunny with a few puffy cumulus clouds here and there…dry as a bone here on Maui.

342pm, the almost totally clear skies continue, it’s a very dry day here in paradise.

 

Well, very long-lasting Tropical Cyclone Nolo has passed us by, although not by much, and is still a very potent hurricane to the southwest of Hawaii. Its intensity is still very impressive, as it clocks in with sustained 155 mph winds, with gusts as high as 190 mph! This qualifies as a major Category 4 Hurricane!

Nolo is topping out in strength now and will begin to wind down tonight, although the models suggest that there could be some re-strengthening later this week…however by then it will be far away from Hawaii. There was some worry that Nolo could come close to Kauai around mid-week, although that has become unlikely at this point.

Interestingly enough, the models are suggesting that we might see the approach of our first cold front of the season, which may approach Kauai early next week. It’s very early for such an occurrence, although we’ll take a cold front over a Category 4 hurricane any day of the week!


Hawaii’s Weather Highlights…as of Monday afternoon: Breezy east-southeast winds with a drier airmass will limit clouds and showers through today. Clouds and showers will increase Tuesday through Thursday, as Nolo passes to the west, with rain bands along the south and east side of the storm…encroaching Kauai and Oahu. Nolo moves away to the northwest by the weekend with trades filling in.

Weather Narrative…as of Monday afternoon: A band of showery cumulus clouds is running nearly parallel and just north of the island chain. A few of these showers may impact windward Kauai and Oahu through the day, but conditions elsewhere should remain dry.

Major Hurricane Nolo is around 420 miles southwest of Honolulu, and has made it`s turn to the northwest. Main impacts in the short-term will be the breezy, but weakening winds across the state, due to the pressure difference between Nolo and the subtropical high far to the northeast, and the southwest swell directed towards the islands.

Nolo will weaken down to a Category 1 hurricane and stall around 250 to 300 miles west of Kauai Tuesday night and Wednesday, then continue on a more west-northwesterly track away from the state through the second half of the week. Winds will remain brisk and gradually veer southeasterly as Nolo gains latitude, then continue out of the southeast through the end of the week.

Rain bands along Nolo`s eastern flank will spread out enough to likely bring an increase in rainfall across Kauai and Oahu, as the southeasterly flow directs showers over populated areas of both islands. Guidance shows varying amounts and lengths of time that the bands will impact the western end of the state, and will ultimately depend on Nolo`s eventual path over the next few days.

By this weekend, trade winds are forecast to build in bringing drier and more stable conditions again.

Fire Weather:  Dry weather conditions are expected to prevail across the state today into Tuesday. An increase in shower activity is expected on Tuesday and Wednesday, as deep tropical moisture makes its way towards the islands as Hurricane Nolo passes west of the area. Fire concern will remain low for now as relative humidity values will remain above critical levels and winds have diminished as well.

Marine Conditions…as of Monday afternoon: Strong to near gale force trade winds and large, rough seas will gradually diminish through tonight as high pressure far north of the state begins to weaken and Hurricane Nolo, several hundred miles southwest of the Hawaiian Islands, moves farther west. The Small Craft Advisory (SCA) for all Hawaiian coastal waters (with the exception of Maalaea Bay) has been extended through tonight. Beyond that point, trade winds are expected to weaken below small craft advisory for most waters.

Higher seas and strong winds may persist for favored channels and waters near Kauai, where the current National Hurricane Center forecast has Nolo tracking around 230 nautical miles west of on Wednesday. Expect moderate to locally strong winds to veer out of the east-southeast to southeast during this time. Winds will gradually ease and back more easterly by Thursday as Nolo moves westward away from the islands.

A mix of long to medium period south-southwest swell and building short to medium south swell from a powerful Hurricane Nolo now located southwest of the Hawaiian Islands will bring advisory level surf to south facing shores of all islands and west facing shores of the Big Island today. The hurricane-generated swell will gradually shift southwest, then west, as Nolo tracks northwest roughly parallel to the islands through Wednesday.

While the forecast currently shows this swell gradually decreasing, and in particular, falling below advisory criteria tonight, Nolo is forecast to remain a major hurricane through Tuesday, which could maintain advisory level surf for longer than currently depicted. By mid-week, these swells will originate from the west and be diminishing as the hurricane will be weaker and it begins to track away from the islands.

East shore surf will slowly decline through Wednesday as trade winds diminish. However, small, medium period swells from distant East Pacific hurricanes will maintain moderate surf during the remainder of the week. On north facing shores, a small medium period swell will fade through Wednesday. Som

Interesting:  Contaminated Soil Poses Hidden Lead Threat Inside Homes

Lead contamination in soil tracked inside homes can cause dangerous indoor lead dust levels even in residences with no interior lead-based paint, according to researchers with the Rutgers Environmental, Occupational and Health Sciences Institute in collaboration with community scientists: members of the general public who participate in data collection under the direction of scientists.

The study, published in the Journal of Exposure Science & Environmental Epidemiology, was conducted in the neighborhood of East Trenton, in Trenton, N.J., which the U.S. Environmental Protection Agency (EPA) added to the Superfund National Priorities List in 2025 after determining there was lead contamination in soil from 19th-century pottery manufacturing plants.

They found 86% of 242 bare surface soil samples collected exceeded the EPA’s 200 parts per million residential soil lead hazard level and nearly 94% exceeded screening levels for multiple sources of lead exposure. “This is especially concerning because all samples were collected from bare soil at the surface, which is the most likely to be accessed by children or tracked into homes,” said Sean Stratton, a recent Rutgers School of Public Health PhD graduate and lead author of the study.
