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

Good day everyone, I hope you have a great Sunday wherever you happen to be spending it.

550am, it’s mostly clear early this morning here in Kula, with a chilly low temperature of 50.5 degrees at my place.

 

Hawaii’s Broad Brush Weather Overview:  Gentle to moderate trade winds will prevail, with afternoon sea breezes along terrain sheltered western slopes of each island. Trade winds will strengthen into the moderate to breezy range as sea breezes diminish Monday onward.

Clouds and passing showers will favor the windward and mountain areas, trending higher in the overnight to early morning hours. Isolated thunderstorms are possible near Kauai. More stable conditions are forecast Monday onward, with brief passing showers mainly forming over windward and mountain areas.

Hawaii’s Weather Details:  A subtropical high pressure ridge north of the Hawaiian Islands will keep trade winds in the forecast through this week. An upper level low roughly 200 miles north of Kauai will continue to drift west, and then weaken as it moves northward Monday away from the area.

A weak low level trough under this upper low, will keep trade winds in the gentle to moderate range for one more day. Upper level forcing from this passing low will enhance shower activity over the western islands, mainly affecting windward and mountain areas in the overnight to early morning hours.

Sea breezes will also develop over terrain sheltered western slopes of each island. Large scale trades and local scale sea breeze winds will converge, producing afternoon clouds and showers over these terrain sheltered leeward locations.

By Monday, the ridge will build into the islands as the upper low weakens and drifts northward away from the area. Trade winds will strengthen into the moderate to breezy range through much of the next week. Stronger subsidence under this ridge will stabilize the atmosphere by lowering the trade wind thermal inversion heights and reducing cloud heights. Expect mostly brief passing showers from Monday onward, as more stable conditions return to the Hawaii area.

Here’s a near real-time Wind Profile of the Pacific Ocean – along with a Closer View of the islands / Here’s the latest Weather Map / Vog map animation

Hawaii’s Marine Environment:  High pressure north of the state will maintain moderate to fresh trade winds. Monday through mid-week, trades are expected to strengthen back to fresh and strong levels, and a Small Craft Advisory will likely be required for the typically windy waters around Maui and the Big Island.

No significant south swells are expected through this upcoming week. However, a series of small south-southwest and southeast swells will keep south facing shores from going flat.

Typical mostly flat summertime conditions will continue along north facing shores.

East shore surf will remain below normal, then trend up closer to seasonal levels early to mid this week, as the trades strengthen over and upstream of the islands.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean: 

Tropical Cyclone 02L (Beryl) is located about 355 miles east-southeast of Barbados…according to the NHC advisory number 8

BERYL IS NOW A VERY DANGEROUS CATEGORY 3 HURRICANE…LIFE-THREATENING WINDS AND STORM SURGE EXPECTED IN THE WINDWARD ISLANDS BEGINNING EARLY MONDAY

Beryl is moving toward the west near 21 mph. A continued quick westward to west-northwestward motion is expected during the next few days. On the forecast track, the center of Beryl is expected to move across the Windward Islands early on Monday and across the southeastern Caribbean Sea Monday night and Tuesday.

Aircraft data indicate that the maximum sustained winds have increased to near 115 mph with higher gusts, making Beryl a very dangerous category 3 hurricane. Continued rapid strengthening is forecast over the next day or so, and Beryl is expected to become an extremely dangerous category 4 hurricane before it reaches the Windward Islands.

Hurricane-force winds extend outward up to 15 miles from the center and tropical-storm-force winds extend outward up to 80 miles.

 

>>> Eastern Tropical Atlantic:

Invest 96L

Showers and thunderstorms continue in association with an area of low pressure located several hundred miles southwest of the Cabo Verde Islands. Environmental conditions appear conducive for additional development of this system, and a tropical depression is likely to form by the middle part of this week while it moves generally westward at 15 to 20 mph across the eastern and central tropical Atlantic.

* Formation chance through 48 hours…medium…40 percent
* Formation chance through 7 days…high…70 percent

 

Caribbean Sea:  There are no active tropical cyclones

Gulf of Mexico:   There are no active tropical cyclone

>>>  Southwestern Gulf of Mexico:

Invest 94L

An area of low pressure located over the southern portion of the Bay of Campeche is producing disorganized showers and thunderstorms. Environmental conditions appear conducive for further development, and a short-lived tropical depression could form before the system moves inland over Mexico on Monday morning. Interests along the Gulf Coast of Mexico should monitor the progress of this system. Regardless of development, heavy rainfall associated with the area of low pressure will continue to affect portions of Central America and Mexico through early next week. An Air Force reconnaissance aircraft is scheduled to investigate the system later today.

* Formation chance through 48 hours…medium…50 percent
* Formation chance through 7 days…medium…50 percent

 

Northeastern Pacific: There are no active tropical cyclones

>>> Offshore of Southern Mexico:

https://www.nhc.noaa.gov/xgtwo/two_pac_7d0.png

A broad area of low pressure is expected to form early this week a few hundred miles south of the coast of southern Mexico. Some gradual development is possible, and a tropical depression could form around midweek while the system moves west-northwestward at 10 to 15 mph.

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

Interesting:  In the Grip of Global Heat

It’s only the beginning of the summer season in the Northern Hemisphere, but Earth is already roasting.

Scientists from NASA’s Goddard Institute for Space Studies recently reported that May 2024, the hottest May in NASA’s global surface temperature analysis, marked a full year of record-high monthly temperatures.

Likewise, NOAA recently reported that January through May 2024 ranked warmest on its 175-year temperature record.

On June 19, 2024, the Northern Hemisphere was running 1.1 degrees Celsius (1.9 degrees Fahrenheit) above normal, according to an analysis of meteorological data from Climate Reanalyzer.

In this context, early summer heatwaves in the Northern Hemisphere have been fierce. Just as Central America and the southwestern and eastern United States saw blasts of heat in May and June, temperatures also soared in the Middle East, South Asia, and Africa.

The series of heat waves has contributed to large numbers of deaths, strained power grids, and challenged meteorological records.
