Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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.

Glenn’s Wednesday comments:  I’m with my friend Bob here at our vacation rental at Sea Ranch, Sonoma County, CA on a working vacation.

439am HST, it’s clear here at Sea Ranch with low clouds just offshore, the low temperature was 44.5 degrees…with a chilly breeze

Two nights ago a racoon opened one of the screen doors in Bob’s room, and came in and ate our two remaining perfectly ripe avocado’s, and ransacked through a full bag of trash we were going to empty today! We could see his paw prints on the floor, and it wasn’t a small animal, it looked more like a grizzly bear paw prints…well, maybe not that big. However, it’s intimidating to have a wild animal invade your private dwelling space!

 

Hawaii’s Weather Highlights…as of Wednesday morning:  Strong and gusty trade winds are expected through Thursday, as a new high builds north of the state. Relatively dry conditions are expected today, with windward and mauka showers tonight into Thursday, as a band of moisture moves from north to south across the state. Moderate to locally breezy trades will briefly return around Friday or Saturday, but trade winds will strengthen once again Saturday night into Sunday.

Weather Narrative…as of Wednesday morning: A high building far north of the state will strengthen the trade winds, bringing windy conditions across the state. A Wind Advisory is in effect for the typical windy areas around Maui County and the Big Island until 6am Thursday. Winds will be strongest through gaps, and over and downslope of ridges through this evening. Wind gusts of 50 mph are expected during this time.

For Oahu and Kauai strong and gusty trades are possible, but confidence was too low to include them in the wind advisory at this time. The combination of strong trade winds and mostly dry conditions will elevate fire weather concerns today. A frontal boundary is expected to move through the island chain tonight into Thursday, which should bring a brief increase of scattered showers, especially over windward and mauka areas.

The strong trade winds should begin to ease some by Friday afternoon down to breezy to locally strong speeds. From Friday through the weekend, we should see our typical trade wind showers most frequent during the overnight and early morning hours over windward and mauka areas. Trade winds should restrengthen back to strong levels Saturday night into Sunday, as another high passes far north of the state.

Fire Weather: Fire weather conditions will remain near critical levels over the next several days, mainly due to the increase in winds that will persist through Thursday. With the trades strengthening under a drier air mass, winds and humidity will likely reach critical thresholds today, while fuel conditions remain below critical thresholds, due to the above average rainfall over the past few months.

Due to the fuels, Red Flag Warnings are not expected at this time, but near critical fire weather conditions are expected through Thursday. Winds should ease slightly with a modest increase of humidities on Friday. Temperature inversion heights will remain between 5,300 and 6,700 feet across the state. The strong low level inversion will make winds quite gusty especially during the afternoons and evenings downwind of terrain over the next several days.

Marine Conditions…as of Wednesday morning: Strong high pressure north of Hawaii is producing fresh to strong winds across the marine areas. Winds may be locally higher through the typical windier channels and waters near Maui County and the Big Island, for which a Gale Warning remains in effect through tonight. A Small Craft Advisory (SCA) remains in effect for all other coastal waters, and this may need to be extended into Thursday. High seas are also forecast later today into Thursday with the arrival of a large north-northwest swell.

Meanwhile, a front will drop south from the northern offshore waters to reach the central waters as it weakens into a trough by tonight. The trough will bring increased shower activity to the area through Thursday. Winds will gradually ease through Saturday as high pressure weakens slightly, but this weekend another strong area of high pressure passes north of the islands, which may lead to another period of strong winds Sunday into early next week.

A large, long-period north-northwest swell (340 degree) swell arrives today and will bring rapidly increasing surf to north and west-facing shores. Surf will reach the advisory level and approach warning level surf tonight and linger into Thursday. A High Surf Advisory remains in effect for north and west-facing shores of Niihau, Kauai, Oahu, Molokai and for north-facing shores of Maui through Thursday afternoon. Surf will decrease Friday followed by a north swell this weekend which could push surf back to advisory levels on Sunday.

Surf along east facing shores will increase today as trade winds strengthen. East shore surf will remain elevated and choppy through Friday, then may diminish slightly this weekend.

A small, long-period south swell may bring a small rise to south shore surf today into Thursday. Surf becomes tiny again Friday into the weekend for south- facing shores.

Can Engineering Solve the Forever Chemical Problem?

Among the technical inquiries spanning topics like cyclodextrin polymers and mass spectrometry that were stacked in Damian Helbling’s inbox was a question about four golden retrievers.

A local woman had contacted Helbling, a professor in Cornell’s School of Civil and Environmental Engineering and a leading researcher of trace organic chemicals in water, wanting to know if it was safe for her dogs to swim in a nearby pond.

“I also have a golden retriever that loves to swim and I absolutely sympathize with this question,” Helbling said, “but I hesitate to give a concrete answer when people ask me such specific questions about the safety of their water. As a researcher, I tend to look at the situation through a totally different lens.”

Damian Helbling, professor of civil and environmental engineering, shows a laboratory sample to doctoral students Florencia Corbo-Ferreira and Fanshu Geng. The researchers are working to better understand, detect and remove PFAS, also known as forever chemicals, from the environment.
