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. 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

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

450am, it’s totally clear early this morning here in Kula, with a chilly low temperature of 51 degrees at my place.

1055am, it’s mostly sunny with a few cumulus clouds drifting around here and there.

435pm, once again late this afternoon, there are practically no clouds in the sky over Maui…it’s very warm too!

747pm, it was quite clear at sunset, although since then we’ve had lots of clouds forming. Nonetheless, the temperature has fallen from a high of 84 degrees…down to a more comfortable 64.4 degrees.

Take Note: Potential Power outages across the state of Hawaii…as of today.

 

Hawaii’s Broad Brush Weather Overview:  High pressure will build north of the Hawaiian Islands today and continue through the week, resulting in breezy trade winds. Fairly stable conditions will keep brief passing showers over windward and mountain areas, mainly in the overnight to early morning hours.

Hawaii’s Weather Details:  An upper level low shown on satellite water vapor imagery is north of the island of Kauai, will weaken as it lifts farther northward. Infrared satellite imagery east (upstream) of the island chain shows fairly stable clouds riding in on the trade winds. These passing stable clouds will not produce much rainfall over the islands in the short term.

The high pressure ridge north of the islands will build into the Hawaii region, producing more stable conditions with less clouds, lower showers, and increasing trade winds into the moderate to breezy range through Friday. Expect limited showers for most windward areas with even fewer showers over the typically drier leeward areas.

Trade wind thermal inversion heights will range from around 5,000 to 6,500 feet in most locations in a fairly stable weather pattern. Some exceptions may include the eastern slopes of Maui and the Big Island where periods of passing rain showers will likely continue…at times.

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 bring fresh to strong trade winds, and persist through most of the week. A Small Craft Advisory has been issued for the waters and channels around the Maui and The Big Island. Trades may weaken slightly Wednesday, before a slight uptick Thursday and Friday.

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 through most of the week. East shore surf will gradually trend up closer to seasonal levels through the middle of this week, as the trades strengthen over and upstream of the islands. A fetch of strong northeast winds well off the California coast should bring a small northeast (050 to 060 degree) swell by this weekend into early next week. Some of this swell should wrap into select north facing exposures as well.

Water levels running roughly 0.5 ft higher than normal around the Big Island combined with the new moon tides could cause minor flooding issues between July 2nd and July 6th, with peak water levels expected on July 4th. During our last full moon, we received reports of some areas of the coastline becoming inundated with the high tide such as Coconut Island and Puhi Bay. A Coastal Flood Statement will likely be needed for the Big Island near the 4th of July. For the other islands, water levels are running just a touch above normal and will likely not reach our criteria of 1 foot above the Mean Higher High Water.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean: 

>>> Central Tropical Atlantic:

Invest 96L

Disorganized showers and thunderstorms have diminished somewhat in association with an area of low pressure located over 1000 miles east-southeast of the Windward Islands. Environmental conditions only appear marginally conducive for additional development of this system, but a tropical depression could still form during the next few days while it moves generally westward at 15 to 20 mph across the central and western tropical Atlantic. Interests in the Lesser Antilles should monitor the progress of this system.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…medium…40 percent

Caribbean Sea:  

Tropical Cyclone 02L (Beryl) is located about 775 miles east-southeast of Kingston, Jamaica…according to the NHC advisory number 14A

CATEGORY 5 BERYL STILL INTENSIFYING IN THE SOUTHEASTERN CARIBBEAN…EXPECTED TO BRING LIFE-THREATENING WINDS AND STORM SURGE TO JAMAICA LATER THIS WEEK

Beryl is moving toward the west-northwest near 22 mph. Beryl is forecast to continue moving rapidly west-northwestward during the next couple of days. On the forecast track, the center of Beryl will move quickly across the southeastern and central Caribbean Sea tonight through Tuesday and is forecast to pass near Jamaica on Wednesday.

Recent data from the NOAA Hurricane Hunters indicates that the maximum sustained winds have increased to near 160 mph with higher gusts. Beryl is now a catastrophic category 5 hurricane on the Saffir-Simpson Hurricane Wind Scale. Fluctuations in strength are likely during the next day or so, but Beryl is expected to still be near major hurricane intensity as its moves into the central Caribbean and passes near Jamaica on Wednesday. Some more weakening is expected thereafter, though Beryl is forecast to remain a hurricane in the northwestern Caribbean.

Hurricane-force winds extend outward up to 40 miles from the center and tropical-storm-force winds extend outward up to 125 miles.

Gulf of Mexico:  There are no active tropical cyclones

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 in a day or so a few hundred miles south of the coast of southern Mexico. Some gradual development of this system is possible thereafter, and a tropical depression could form during the next few days while it moves west-northwestward between 10 to 15 mph.

* Formation chance through 48 hours…low…20 percent
* Formation chance through 7 days…medium…50 percent

Interesting:  Antarctic Ice Shelves Hold Twice as Much Meltwater As Previously Thought

Slush – water-soaked snow – makes up more than half of all meltwater on the Antarctic ice shelves during the height of summer, yet is poorly accounted for in regional climate models.

Researchers led by the University of Cambridge used artificial intelligence techniques to map slush on Antarctic ice shelves, and found that 57% of all meltwater is held in the form of slush, with the remaining amount in surface ponds and lakes.

As the climate warms, more meltwater is formed on the surface of ice shelves, the floating ice surrounding Antarctica which acts as a buttress against glacier ice from inland. Increased meltwater can lead to ice shelf instability or collapse, which in turn leads to sea level rise.
