Hawaii’s Mountains – Here’s a link to the live webcams on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii, and atop the Haleakala Crater (~10,023 feet) on Maui. 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 Wednesday comments:  I’m home here in upper Kula, Maui, Hawaii.

It’s clear to partly cloudy here in upper Kula early this morning, with my low temperature 55 degrees.

 Weather Wit of the day:  Spring – When car thieves switch from sedans to convertibles

 

Hawaii’s Broad Brush Weather Overview:  Moderate to locally breezy trade winds will persist into early next week, as high pressure holds far north of the state. Rainfall will be focused over windward slopes, though showers will be slightly enhanced and will periodically pass over leeward areas during the next couple of days.

Hawaii’s Weather Details:  Radar and satellite imagery show scattered showers moving into windward areas on the trades, with some occasional spill over into leeward areas. While these showers have been fast moving, some have produced brief moderate to heavy rainfall, with select windward areas across Kauai and Oahu receiving between a quarter and half an inch of rain.

A strong high centered far northwest of the state will weaken slightly as it gradually progresses east-southeast, maintaining moderate to locally breezy trades across the island chain over the next several days. Relatively weak troughing aloft will provide modest instability, which will allow for slightly enhanced shower activity through Friday, as batches of moisture continue to be brought in on the trades. This will likely lead to brief periods of moderate to heavy rain over windward areas, with some showers occasionally making it over the island terrain into leeward areas as inversion heights remain elevated.

Shower activity will diminish over the weekend into early next week, as a mid-level ridge builds overhead, increasing atmospheric stability and lowering inversion heights. This more stable trade wind pattern will help to better confine showers to windward areas, with fewer showers passing over into leeward areas. The high sliding eastward well north of the state will maintain moderate to locally breezy trade winds through early next week.

Hawaii’s Marine Environment:  Fresh to strong easterly trades will persist through the weekend, as the surface ridge remains anchored north of the islands. A Small Craft Advisory will persist each day for the typical windier waters and channels around Maui County and the Big Island.

Surf along exposed north and west-facing shores will remain up around average through Thursday, due to a medium-period northwest swell that filled in Tuesday afternoon. This swell will gradually be shifting out of the north over the next couple of days.

Surf along south-facing shores will remain below average through Friday as a background south swell fades. A fresh long-period south-southwest swell is expected to arrive over the weekend, bringing an upward trend with above-average surf. Forerunners should begin filling in Friday, with the swell peaking late Saturday through Sunday. This swell has peaked slightly above guidance at the American Samoan buoy overnight, which will translate to a peak locally late Saturday into Sunday, likely enough to drive surf to the advisory level.

Surf along east-facing shores will remain rough and choppy, with heights hovering around average into the second half of the week. Heights could dip below average by the weekend, due to a weakness forming in the ridge far northeast of the area, leading to the upstream trades diminishing. A return to average levels is expected later this weekend into early next week as the trades strengthen upstream.

Interesting:  After 17 Years Underground, Massive Cicada Brood to Swarm U.S.

After hiding underground for the last 17 years, billions of cicadas will take to the skies this summer, from Tennessee to Cape Cod.

These cicadas, known as Brood XIV, will cover more of the U.S. than any other 17-year brood. They are also the original brood from which all other 17-year broods branched off.

After surfacing in May and June, these cicadas will issue their noisy, chirping mating call for just a few short weeks before laying eggs and dying. Their offspring will remain dormant underground for another 17 years.
