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 Thursday 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 partly cloudy here at Sea Ranch with low clouds just offshore and lots of high cirrus clouds too, the low temperature was 44.5 degrees…with a chilly breeze

 

Hawaii’s Weather Highlights…as of Thursday morning: Strong trade winds are expected today as high pressure continues to build south toward the state. Windward and mauka showers increase as a decaying cold front moves from north to south across the state. Moderate to locally breezy trades will return Friday.

Weather Narrative…as of Thursday morning: A weakening front will bring some deeper moisture south through the islands today. Increased shower coverage is expected over mostly windward and mauka areas, but a few may make it into leeward areas too. The Wind Advisory has been cancelled but winds could still be strong and gusty today…although likely remain below advisory thresholds.

The strong trade winds should ease some Friday down to breezy to locally strong speeds. Another high pressure ridge will slide east, well to the north of the state this weekend. Some increase in the trades is possible again Saturday night and Sunday, before the high stalls to our northeast early next week. A reduced pressure gradient should allow trades to relax some by that time. Brief pulses of better moisture in the trades will keep typical trade wind showers over windward and mauka areas, mostly during the overnight and early morning hours through the period.

Fire Weather: With strong trades and low humidity levels critical fire thresholds may be reached today. However, 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. Winds should ease slightly with a modest increase of humidities on Friday. Temperature inversion heights will remain between 6,000 and 7,000 feet across the state.

Marine Conditions…as of Thursday morning: Strong high pressure north of Hawaii will maintain fresh to near gale force winds across the marine areas through tonight. The Gale Warning has been discontinued in favor of a Small Craft Advisory (SCA) which covers all coastal waters. The SCA has been extended through tonight, with a gradual tapering of winds forecast and some uncertainty on how widespread strong trades will be by Friday. Look for high seas with a large north-northwest swell moving through the area.

A weakening front will drop south across central waters today as it weakens to a trough. This disturbance will bring increased shower activity to the area until it dissipates tonight. Though trade winds diminish some for Friday and Saturday, high pressure restrengthening northeast of the islands may bring more widespread strong winds Sunday and Monday to all waters.

Buoy 51201 near Waimea Bay observed the peak of the large, north-northwest swell late last evening with a 15 second period. A High Surf Advisory (HSA) remains in effect for north- facing shores of Kauai, Oahu, Molokai and Maui and west- facing shores of Kauai and Oahu.

The large swell will generally maintain, before declining this afternoon and falling below advisory criteria tonight. Surf will continue to decrease Friday, but will see a small rise on Saturday, with a new north-northwest swell, followed by a more significant north swell which could push surf back to advisory levels on Sunday.

Surf along east-facing shores will remain rough and choppy due to the strong trade winds through Friday, then may diminish slightly this weekend. A small, long-period south swell may bring a small rise to south shore surf today. 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.
