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, 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.

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:  Moderate to locally breezy trade winds will prevail across the islands through the work week into the upcoming weekend. A slug of deep moisture will bring an increase in trade wind showers particularly to windward slopes and coasts, as it moves from east to west across the islands today and tonight. Typical trade wind weather featuring mainly windward and mountain showers will return by Tuesday, and continue through the upcoming weekend.

Hawaii’s Weather Details:  Weather maps show a high centered far north-northeast, which is generating moderate to locally breezy trade winds across the island chain. Satellite imagery shows partly to mostly cloudy conditions across the state, with cloud coverage the greatest in windward areas. Radar imagery shows numerous to widespread shower activity over windward areas from Oahu eastward, with scattered showers moving into windward Kauai.

High pressure north-northeast of the state will drift westward to a location due north of the islands today, then remain nearly stationary through Thursday, keeping moderate to locally breezy trade winds in place. The high will shift eastward and weaken slightly Friday through the upcoming weekend, which could bring a slight easing in the trade wind speeds.

Meanwhile, a mid-level trough will bring an area of deeper moisture from east to west across the islands today and tonight. Showery weather can be expected in windward areas, as this batch of deeper moisture moves through. We should see a return back to more typical trade wind weather beginning this afternoon over the Big Island and by Tuesday morning over Kauai. Typical trade wind weather featuring mainly windward showers and the occasional leeward spillover will then continue Tuesday through the upcoming weekend.

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:  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 985 miles east of the Northern Leeward Islands

GORDON SHOWING LITTLE CHANGE IN STRENGTH

According to the NHC Advisory number 21

The depression is moving toward the west near 7 mph. A gradual turn toward the west-northwest and northwest at a slower forward speed is expected during the next day or so, followed by a turn toward the north and north-northeast by Wednesday. Maximum sustained winds remain near 35 mph with higher gusts. Little change in strength is forecast during the next 48 hours.

Potential–Tropical Cyclone 08L…which is located about 70 miles south-southwest of Cape Lookout, NC

STRONG WINDS AND HEAVY RAINS CONTINUE SPREADING OVER PORTIONS OF SOUTHEASTERN NORTH CAROLINA

According to the NHC Advisory number 4

The system is moving toward the north-northwest near 5 mph. A northwestward motion is expected during the next day or two. On the forecast track, the low will reach the coast of South Carolina this afternoon and then move inland across the Carolina’s tonight through early Wednesday.

Surface observations indicate that maximum sustained winds are near 50 mph with higher gusts. Little change in strength is expected before the system reaches the coast, but steady weakening is anticipated after the system moves inland. The low is forecast to dissipate over the Carolina’s by early Wednesday.

Tropical-storm-force winds extend outward up to 175 miles from the center. A National Ocean Service station at Wrightsville Beach, North Carolina, recently reported a sustained wind of 51 mph and a gust of 67 mph.

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.
