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 Sunday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s mostly clear with a few clouds here in Maui County early this morning. The low temperature at my place was a chilly 51.5 degrees…with a relative humidity of 78%.

I played pickleball again this morning in Haiku, which was always vigorous and fun. I’m back home this afternoon here in upper Kula, where it’s mostly cloudy.

Hawaii’s Broad Brush Weather Overview: An upper-level low centered several hundred miles north of the state will continue to move south through midweek, then weaken and slide off to the west. This will bring a chance for heavier showers and a few thunderstorms from Wednesday into Friday evening. Relatively light southeast surface winds continue through Tuesday, with stronger trades kicking in Wednesday into lasting into next weekend.

Hawaii’s Weather Details: Afternoon sea breezes and isolated showers mainly in leeward areas continue. This pattern will generally continue through Tuesday. The largest area of showers has been over southwest Kauai. In addition, a band of higher clouds, associated with an upper level jet stream, was moving through parts of the state from the southwest.

A strong upper level low and its surface reflection will continue to move south through Wednesday afternoon, reaching the western islands (it will be centered roughly overhead) before sliding off to the west, and weakening late this week into next weekend.

This will bring cooler air aloft, increasing instability and the chance for stronger showers and thunderstorms, especially Wednesday through Friday evening. Thunderstorms are in forecast now, as confidence is high that they will occur. The most likely area is the western part of the state, but we can’t rule out thunderstorms in the east as well.

The other significant change this coming week will be the surface winds. Relatively light southeast winds will give way to easterly trades Wednesday. Wind speeds will increase, especially in the usual topographically driven areas. Small craft advisories may be needed beginning Thursday.

Fire weather:  Light winds and isolated showers will help maintain fire weather below critical thresholds for the next several days. Inversion heights will range from 6,000 to 8,000 feet.

Hawaii’s Marine Environment: Broad troughing north of the islands will keep the local pressure gradient somewhat weak, maintaining mainly gentle to moderate trade winds over coastal waters into Tuesday. The trough will gradually fill in late Tuesday and Wednesday, and building surface high pressure north will drive strengthening trade winds.

Small Craft Advisory conditions may develop over the typically windy waters around the Big Island and Maui as early as Wednesday night and likely by Thursday. As trades strengthen, a disturbance aloft will drift southward over the islands and bring instability.

The small to moderate northwest swell will give way to long period forerunners of a new northwest (320 deg) swell building late and through the night. Surf should peak at High Surf Advisory levels Monday and Tuesday for most north and west shores from Kauai to Maui. Surf will gradually decline Thursday and Friday, with some small northwest swell lingering into next weekend. Tiny background south swell will prevail through the week.

A slight increase to near seasonal norms, as medium-period easterly swell from a distant tropical cyclone moves across the area. East shore surf will be small Tuesday, then increase and become rough during the second part of the week, as trade winds build over and upwind of the islands.

Water levels during morning high tides will continue to gradually lower during the next couple of days. Water levels peaked just below the flooding level at most stations Saturday, with conditions expected to be borderline at high tide in the mornings.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  

Central Tropical Atlantic:

Invest 97L

>>> Showers and thunderstorms have increased in association with a small area of low pressure located about 900 miles west-southwest of the Cabo Verde Islands. Environmental conditions are forecast to become more favorable for further development of this system during the next few days, and a tropical depression is likely to form by the middle part of this week while it moves to the west-northwest then northwest at 15 to 20 mph across the central tropical Atlantic.

* Formation chance through 48 hours…medium…60 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 cyclone

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

 

Northeastern Pacific: 

South of Southern Mexico:

>>> A large area of showers and thunderstorms, located a couple of hundred miles south of the coast of southern Mexico, is associated with an elongated area of low pressure. Little development is expected to occur during the next few days while it meanders well offshore. Towards the end of the work week, environmental conditions appear more conducive for development, and a tropical depression could form while the system drifts northward then northwestward near or just offshore of the coast of southern Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…medium…40 percent

 

North Central Pacific: There are no active tropical cyclone

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

Interesting:  How Lemurs Are Laying the Groundwork for Interstellar Travel

After astronauts wake up from hibernation, will they still be able to drive the spacecraft? Duke researchers are studying lemurs to find out.

From fairy tales – such as Sleeping Beauty and Rip Van Winkle – to science fiction films, including Planet of the Apes and Alien, people have long been fascinated by the concept of humans undergoing prolonged periods of sleep.

Ana Breit’s fascination started with her studies of body temperature regulation and hibernation. Her early research focused on bats, which can double their weight before entering a months-long hibernation state. A year ago, when she joined the Duke Lemur Center as a research scientist, she began studying Malagasy fat-tailed dwarf lemurs. “Being able to study hibernation in the closest relatives to humans able to hibernate is an incredible opportunity,” said Breit, who, along with Duke Lemur Center colleagues, received a $30,000 NC Biotech Flash Grant to study hibernation at warmer temperatures.

While many space films have depicted humans in cryogenic tubes during long space flights, in reality, this kind of “synthetic hibernation” would lead to numerous health–related challenges, including a loss of cognitive function.
