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.

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 evening: Tropical Storm Lala is moving away to the west but will continue to affect the west end of the state . Areas of damaging winds may persist, mainly across Kauai County, and the threat of heavy flooding rainfall will continue on most island

As Lala moves west of Kauai tonight and Monday, strong easterly winds will slowly diminish, and the threat of flooding will decrease. Trade wind flow will prevail Tuesday through Thursday, after which time winds will veer to east-southeast.

Weather Narrative..as of Sunday evening: Radar and satellite show widespread showers, some quite heavy, across most islands. The heaviest showers have been over eastern Maui, eastern Oahu, northern Big Island, and most of Kauai County. Total rainfall has been extreme, with over 35 inches on Big Island, 10 to 15 inches on Maui, 5 to 10 inches on Molokai, Lanai, and Oahu, and 10 to 15 inches on Kauai.

Wind damage (roofs off, trees down, power lines down, etc) has been widespread, but speeds are decreasing and should decrease more through the night. Although overall rainfall areal coverage is trending down, significant heavy rain continues in strong convective showers and even a few thunderstorms.

Tropical Storm Lala continues to move away to the west, well southwest of Kauai. Tropical storm warnings remain for Kauai County, but have been cancelled for all other islands. A Flash Flood Watch remains for all islands except Big Island.

As Lala departs to the west, winds will ease to moderate to locally breezy trades. Windward areas may remain wet with some risk for flooding due to a band of moisture trailing Lala. Precipitable moisture will remain a little higher than normal through the upcoming week, leading to relatively wet trades. These trades will veer to east-southeasterly Thursday night, and remain that way through next weekend. This will slightly shift the “windward” areas late in the week.

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.

Tropical cyclone formation is not expected during the next 7 days.

>>> Caribbean Sea: There are no active tropical cyclones

Tropical cyclone formation is not expected during the next 7 days.

Northeast Pacific: 

 

>>> South of Mexico:

An area of low pressure could form several hundred miles south of the coast of southern Mexico around the middle part of the week. Gradual development of this system is possible thereafter, and a tropical depression could develop towards the end of the week or next weekend while the system moves west-northwestward, while staying south of Mexico.

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

 

>>> Western portion of the eastern Pacific:

A broad area of low pressure could form well to the southeast of the Hawaiian Islands during the middle to latter part of the week. Environmental conditions appear conducive for gradual development of this system, and a tropical depression could form towards the end of the week and into the weekend, while the system moves generally westward across the western portion of the east Pacific and into the central 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 170 miles west-southwest of Lihue, Hawaii

LALA HOLDING STEADY SOUTHWEST OF KAUAI COUNTY …OUTER BANDS OF LALA BRINGING HEAVY RAINFALL AND GUSTY WINDS TO PORTIONS OF THE MAIN HAWAIIAN ISLANDS

According to the NHC advisory number 19…

Lala is moving toward the west near 16 mph (26 km/h). A westward motion is forecast through Tuesday, followed by a turn toward the west-northwest on Wednesday. Maximum sustained winds are near 65 mph (100 km/h) with higher gusts. Little intensity change is expected over the next day or two. Some restrengthening is forecast thereafter, and Lala could become a hurricane again by Wednesday. Tropical-storm-force winds extend outward up to 140 miles (220 km) from the center. The estimated minimum central pressure is 994 mb (29.36 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.
