~~~ Hawaii Weather Narrative ~~~

 

Glenn’s Monday comments:  I’m home here in upper Kula, Maui, I hope you have a great Monday wherever you happen to be spending it.

505am, it’s partly cloudy and unusually warm early this morning here in upper Kula.

846am, cloudy and I had light sprinkles falling while I was out on my first walk of the day. I understand it is windy and wet over along the windward side of east Maui.

1006am, here in upper Kula we’re finally getting some light showers, although nothing like what the windward sides of the islands received overnight into early this morning.

344pm, the cloudy skies this morning have backed off quite a bit, leaving partly sunny skies this afternoon…along with very muggy conditions.

5pm, it’s so humid, way more muggy than usual up here in Kula, I don’t want to imagine how it is down closer to the coast!

MINOR COASTAL FLOODING DURING HIGH TIDES THROUGH TUESDAY…Peak monthly high tides combined with water levels that are running higher than predicted will lead to minor flooding along the shoreline and in low-lying coastal areas for the next several days. Coastal flooding is most likely around the peak high tide, occurring each day around late morning or early afternoon.

 

Hawaii’s Broad Brush Weather Overview:  Locally breezy trade winds will continue to bring humid and somewhat wet conditions tonight, especially for windward areas. Drier trade wind weather will prevail Tuesday into the weekend, with moderate showers focused over windward slopes.

Hawaii’s Weather Details: After a very wet night for most windward areas, diurnal trends led to a significant decrease in rainfall by mid-morning, and more recently, only a few stations on Kauai have registered more than a quarter of an inch of rain. Isolated heavy showers are flaring on the upper slopes of Mauna Loa this afternoon, but other leeward areas have seen little shower activity today.

The fuel for the rainfall is moisture accompanying a mid-level trough that is drifting westward over the island chain. Look for an increase in shower frequency over windward areas tonight. With some drier trade wind flow moving in from the east and undercutting the moisture, rainfall totals should be significantly less than last night. However, expect humid conditions to linger.

The deeper moisture will move off to the west Tuesday, bringing a less active shower pattern. High pressure north of the state will generate moderate to locally breezy trade winds, with a brief decline in the trades possible around Thursday and Friday. While a ridge aloft will bring stability, the mid- level trough will linger nearby into Wednesday, which will keep shower chances a bit higher than normal. Drier conditions are due Thursday and Friday and likely into Saturday.

While a ridge aloft will maintain stability over the islands through much of the week, an upper-level trough will persist to the west. The main effect of this feature will be periods of high clouds overhead. Models suggest that a low aloft may develop Sunday and Monday and north of Kauai. At this time, it does not look like it will affect local weather significantly.

Hawaii’s Marine Environment:  Moderate to locally strong trade winds will hold through Thursday, as a strong high meanders far north of the islands. A Small Craft Advisory (SCA) has been expanded for all waters surrounding Maui County and the Big Island, and remains in effect for the typically windy waters around the Big Island and Maui County through Tuesday night. The SCA advisory may need to be extended through Thursday. The high will weaken and move eastward late Thursday and Friday, leading to a slight decline in the trades.

Surf across most shores will be below seasonal average through the week. Surf along east facing shores will remain choppy through Thursday, due to persistent trades locally and upstream of the islands. A decrease in trade winds will cause east shore surf to decline Friday.

South facing shores will continue to decline over the next few days. A small southwest pulse out of the Tasman Sea could produce a slight rise in surf Friday. Aside from trade wind wrap, surf along north facing shores will be minimal through Wednesday, and a tiny northwest swell will be possible Thursday or Friday.

The combination of seasonally high astronomical tides and water levels running around 6 inches higher than predicted, will produce localized coastal inundation each afternoon through Tuesday.

World-wide Tropical Cyclone Activity

 

Atlantic Ocean: 

Tropical Cyclone 07L (Gordon)…which is located about 935 miles east of the Northern Leeward Islands

GORDON EXPECTED TO TURN NORTHWARD ON TUESDAY AND COULD RE-INTENSIFY BY MID-WEEK

According to the NHC Advisory number 23

The depression is moving toward the west near 3 mph. A turn toward the north is expected during the next day or so, followed by a turn toward the north-northeast on Wednesday. Satellite wind data indicate that the maximum sustained winds are near 35 mph with higher gusts. Gordon could gradually re-intensify by midweek and become a tropical storm again.

Potential–Tropical Cyclone 08L…which is located about 45 miles west of Cape Fear, NC

LIFE-THREATENING FLASH FLOODING AND GUSTY WINDS CONTINUE ACROSS PORTIONS OF SOUTHEASTERN NORTH CAROLINA

According to the NHC Advisory number 5

The system is moving toward the north-northwest near 7 mph. A northwestward motion is expected during the next day or so, and the low will move inland across the Carolinas tonight and Tuesday. Surface observations indicate that maximum sustained winds have decreased to near 35 mph with higher gusts. Continued weakening is expected during the next day or so, and the low is forecast to dissipate over the Carolina’s by early Wednesday.

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

Interesting:  Researchers Drill Down on Mine Waste Monitoring Using Drones and Sensors

University of Queensland researchers are developing new ways to monitor mine waste using drones and ground sensors to improve safety and land rehabilitation across mine sites.

Lead investigator Dr Thierry Bore from the School of Civil Engineering said safe management and rehabilitation of mine waste was one of the biggest challenges facing the industry.

“Mine waste is currently monitored using expensive and challenging drilling techniques and sometimes the results aren’t accurate,” Dr Bore said.

“We are developing advanced technologies to capture electromagnetic measurements which could tell us what is happening in the soil, rock and water underneath.
