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 Monday 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 53 degrees…with a relative humidity of 76%.

Hawaii’s Broad Brush Weather Overview: An upper-level low centered several hundred miles north of the state will continue to move south through mid-week, 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 lasting into the weekend.

Hawaii’s Weather Details: Satellite imagery shows that we have a few showers moving across the islands. A few low clouds are hanging around where there are showers, with some upper level clouds associated with a jet stream that is moving out of the area. Look for our local winds to remain light today.

A strong upper level low will continue to move south through Wednesday afternoon, reaching the western end of the state (roughly centered overhead),  before moving to the west and weakening late this week into the weekend. This will bring cooler air aloft, increase instability and the chance for stronger showers and a few thunderstorms. With confidence increasing thunderstorms have been introduced into the forecast. The most likely area is the western part of the state, but we can’t rule out thunderstorms over Maui County and the Big Island.

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 windiest areas.

Fire weather:  Light winds and isolated to scattered showers will help maintain fire weather below critical thresholds for the next several days. Inversion heights will range from 6,000 to 7,000 feet.

Hawaii’s Marine Environment:  A trough will linger north of Hawaii resulting in light east to southeast winds across the state. The trough will fade while high pressure builds far to the northeast Tuesday night, with trade winds building in for the rest of the week. An upper low will also track over the islands beginning around Tuesday night, resulting in possible thunderstorms Wednesday through Friday.

A long period northwest swell has arrived and will peak tonight. A High Surf Advisory is now posted for north and west facing shores of Niihau, Kauai, Oahu, Molokai and north facing shores of Maui through Tuesday. Surf will drop off Tuesday night through Thursday.

Small, medium period south swell will continue through the week, with minor pulses of longer periods arriving tonight and again on Saturday. East shores will remain small due to light winds, but should begin to increase beginning Wednesday as trades strengthen.

There may be some minor flooding within low laying areas during high tide.

 



World-wide Tropical Cyclone Activity

 

Atlantic Ocean:  

Tropical Cyclone Lorenzo is located about 1180 miles west of the Cabo Verde Islands

LORENZO REMAINS POORLY ORGANIZED OVER THE TROPICAL ATLANTIC

According to the NHC advisory number 3

Lorenzo is moving toward the northwest near 12 mph and this motion is expected through Tuesday, followed by a turn to the north Tuesday night. A northeastward motion is expected on Wednesday. Maximum sustained winds remain near 50 mph with higher gusts. Little change in strength is forecast during the next day or so, but some gradual intensification is possible later in the week. Tropical-storm-force winds extend outward up to 160 miles from the center. The estimated minimum central pressure is 1002 mb (29.59 inches).

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 broad trough of low pressure located a couple hundred miles south-southwest of Guatemala is producing disorganized showers and thunderstorms. Little development is expected during the next few days while the system meanders well offshore. Towards the end of the 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

Interesting:  Parched Soils Can Spark Hot Drought a Nation Away

A new study found compound drought-heatwave events are rippling farther and lasting through the night, raising risks for southwestern North America.

Dry soils in northern Mexico may trigger episodes of simultaneous drought and heatwave hundreds of miles away in the southwestern United States, such as Arizona, New Mexico, and Texas, according to a new study. These “hot droughts” in the region increasingly persist through consecutive days and nights rather than easing up after sundown, the research also found, leaving no window for afflicted areas to recover.

Hot drought can kill crops, worsen wildfire risk, and shock workers and outdoor enthusiasts with unexpectedly high temperatures, all more than either drought or heat alone can do. Scientists involved in the study say the findings could help communities better anticipate and prepare for these stressful events in advance, such as by limiting outdoor working hours, keeping medically vulnerable individuals inside, and opening cooling centers when soils far upwind desiccate.

The study appears in Geophysical Research Letters, AGU’s journal for high-impact, innovative, and timely articles on major advances across the geosciences.
