I’ll be back as soon as possible after the power returns…if that happens. I have limited ability to do any updating…as the power is still off

 

>>> Be safe everyone, and if you can, stay home and off the wet roads here in Hawaii…makes sense right?!

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. Here’s the webcam for the (~10,023 feet high) Haleakala Crater on Maui (out of operation). 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 at home here in upper Kula, Maui, Hawaii

435pm, working on one small laptop screen, and on limited battery power, although I’ll do my best to do what I can, in keeping current information coming to you.

 

 

Hawaii’s Weather Highlights…as of Sunday afternoon: Tropical Storm Lala will continue to affect the state today as it moves westward to the south of Oahu and Kauai. Areas of damaging winds will persist, mainly across the western end of the state, and the threat of heavy flooding rainfall will continue on all islands. As Lala moves west of Kauai tonight and Monday, strong easterly winds will slowly diminish, and the threat of flooding will decrease. A drier moderate to locally breezy trade wind flow will prevail Tuesday through the end of the work week.

Weather Narrative..as of Sunday afternoon: Lala was moving WNW at 14 kt, or 16 mph. Tropical Storm Warnings remain in effect for all islands except the Big Island. Strong winds and heavy rain were still occurring over parts of all islands still within the Tropical Storm Warning, although rainfall over Oahu has recently decreased. There is still a chance for heavy precipitation to occur there this afternoon and tonight. A Flash Flood Watch remains in effect for all islands.

A large convective band remains attached to Lala and extends across Kauai County, Oahu, and Maui County. This band has been slow to move, and has resulted in nearly continous rainfall for many areas. Six-hour rainfall amounts range broadly from up to 4 inches on Kauai, up to 6 inches on Oahu and Maui, and up to 4 inches on Molokai and Lanai. Additional rainfall this afternoon will vary greatly, depending on exactly where the rainband moves, but amounts of 2 to 4 inches, with isolated higher amounts, are forecast.

Marine Conditions…as of Sunday afternoon: Tropical Storm Lala was moving west- northwest at 13 kts with its low level center approximately located 140 nm west-southwest of Honolulu. A Tropical Storm Warning is in effect for all the Hawaiian coastal waters around Maui through Kauai and a Small Craft Advisory is in effect for windward and leeward coastal waters around the Big Island.

Marine conditions are expected to gradually improve tonight through tomorrow. Large east-facing shore surf peaked last night on Big Island and Maui as former Hurricane Lala approached and passed just south of Big Island. Surf for the east-facing shores of Oahu and Kauai is peaking at advisory levels this morning. High Surf Advisories are now in effect for all east-facing shores through 2 PM HST this afternoon, but might need to be extended for at least Kauai. Overall, surf will gradually fall below advisory levels along all east facing shores as Lala progresses further northwest. North-facing surf will remain rough today as a result of this short period, Lala wind wave-driven chop in tandem with an east swell wrap.

South-facing shore surf will stay below advisory thresholds but remain elevated from a combination of lingering medium period south swell and Lala short period east swell. South shores will likely experience a minor boost in surf from trailing short period east swell energy from Lala as it travels into the far west offshore waters Monday morning. Longer period south swell energy generated from gales just east of New Zealand will begin arriving late this week.

Northeast Pacific: 

Post-Tropical Cyclone 08E (Hernan)…is located 1760 west of the southern tip of Baja California – Last Advisory

HERNAN HAS BECOME A REMNANT LOW

According to the NHC advisory number 12…

The post-tropical cyclone is moving toward the west near 12 mph and this general motion is expected to continue through the next few days. Maximum sustained winds are near 30 mph with higher gusts. Slow weakening is forecast to occur over the next couple of days before dissipation occurs on Tuesday. The estimated minimum central pressure is 1009 mb (29.80 inches).

 

>>> South of Mexico:

An area of low pressure could form several hundred miles south of the coast of southern Mexico around the middle portion of next week. Some gradual development of this system is possible thereafter while the system moves west-northwestward well south of Mexico.

* Formation chance through 48 hours…low…near 0 percent
* Formation chance through 7 days…low…30 percent

 

>>> Western portion of the eastern Pacific:

An area of low pressure is expected form well to the west-southwest of the southern tip of the Baja California Peninsula early next week. Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form during the middle to latter portions of next week while it moves generally westward across the western portion of the east Pacific.

* Formation chance through 48 hours…low…near 0 percent.
* Formation chance through 7 days…medium…50 percent

 

Central North Pacific: 

Tropical Cyclone 01C (Lala)…is located about 30 miles southwest of South Point, Hawaii

LALA’S EYEWALL BRUSHING THE SOUTHERN PORTION OF THE BIG ISLAND …DAMAGING WINDS AND HEAVY RAIN WILL PERSIST ACROSS THE BIG ISLAND THROUGH TONIGHT AND SPREAD WESTWARD ACROSS THE SMALLER ISLANDS ON SUNDAY

According to the NHC advisory number 15…

Lala is moving toward the northwest near 9 mph. Some erratic motion remains possible into tonight while Lala interacts with the Big Island of Hawaii. After passing the Big Island, Lala is expected to turn westward on Sunday with an increase in forward speed, as the core of the storm remains south of the smaller Hawaiian Islands, and the easternmost Northwestern Hawaiian Islands through the early part of next week. Maximum sustained winds have increased to near 80 mph with higher gusts. The intensity of Lala is forecast to remain steady over the next few hours as the hurricane remains near South Point of the Big Island. Thereafter, steady weakening is expected later tonight into Sunday as Lala passes south of the smaller main Hawaiian Islands. Some restrengthening is possible early next week. Hurricane-force winds extend outward up to 45 miles from the center and tropical-storm-force winds extend outward up to 175 miles. The estimated minimum central pressure is 985 mb (29.09 inches).

Interesting: Amid Drought, Hundreds of French Rivers Are Drying Up

An ongoing drought in Europe has sapped French rivers. Officials say that 43 percent of small waterways in France have been partially or completely dried up.

Of the more than 3,000 small waterways in France, 1,373 have seen their flow interrupted or halted, according to an analysis from the French Office for Biodiversity. The agency said rivers were desiccated in every region, describing the drying as “the most critical situation ever observed at this time of year.”

Large waterways have also been hard hit. On the Loire River, water levels typically drop in the summer, inhibiting boat travel, but this year sightseeing boats had to suspend operations a month earlier than usual as the river dried up. In Paris, the Seine is being sustained by flows released from reservoirs that stored up surplus water over the winter.
