Hawaii’s MountainsHere’s a link to the live web cam on the summit of near 13,800 foot Mauna Kea on the Big Island of Hawaii. This web cam is available during the daylight hours here in the islands…and when there’s a big moon shining down during the night at times. Plus, during the nights you will be able to see stars, and the sunrise and sunset too… depending upon weather conditions. Here’s the Haleakala Crater webcam on Maui – if it’s working.

Tropical Cyclone activity in the eastern and central PacificHere’s the latest weather information coming out of the National Hurricane Center, covering the eastern north Pacific. You can find the latest tropical cyclone information for the central north Pacific (where Hawaii is located) by clicking on this link to the Central Pacific Hurricane Center. A satellite image, which shows the entire ocean area between Hawaii and the Mexican coast… can be found here. The 2012 hurricane season is over in the eastern and central Pacific… resuming on May 15th and June 1st 2013.

~~~ Hawaii Weather Narrative ~~~

Returning trade winds through Friday morning, then faltering again later Friday into the weekend. Here’s a weather chart showing a near 1034 millibar high pressure system, located far to the northeast of the islands. This high pressure cell has an associated ridge of high pressure extending southwest from its center, over the Kauai at the time of this writing. Meanwhile, a cold front has stalled in its approach…to the northwest of Kauai. The trade winds will finally resume statewide by Wednesday, although will slack-off again early Friday, as the next cold front approaches the Kauai side of the chain this weekend. The localized voggy weather will stick around until the trade winds finally ventilate it away…although it appears that more in on the horizon by this weekend.

Satellite imagery shows clear to partly cloudy skies over the island chain…with a weakening cold front stalled to the northwest of Kauai.  The afternoon clouds that formed during the afternoon hours, will evaporate for the most part during the overnight hours. Here’s the looping radar image, showing showers falling over the island of Oahu, at the time of this writing, with very few elsewhere. As the winds begin blowing more from the east and northeast with the departure of the cold front, we’ll see some modest increase in windward biased showers falling locally…mostly during the night and early morning hours. We’ll see more afternoon clouds developing around the leeward sections Friday into the upcoming weekend, with showers falling locally.

The computer models continue showing another late season cold front approaching the island chain…Friday into the weekend.
Despite it being late in the spring season for such an occurrence, the most reliable models are continuing to show its approach, which could bring some increase in showers to the state. It would also bring lighter winds from the south to southeast directions, and potentially more voggy conditions…and that chance of increased showers. These showers will likely be of the convective variety, falling from clouds that develop over the interior sections during the afternoon hours. There will continue to be some necessary fine tuning of the particulars over the next several days.

Here on Maui [530pm HST]:
  The weather remained pretty static today, at least in the leeward areas…including the upcountry slopes. The trade winds began to make an appearance on both the Big Island, and Maui, although didn’t make it further into the island chain than that. The volcanic haze is still very much present this evening, and could easily be called thick! Looking over towards the West Maui Mountains, from here in Kula, they are totally out of sight…due to the vog. We had a few showers around today, although they were more active earlier in the afternoon hours…especially around Kauai. Oahu, and the Big Island. It was another very warm day here on the valley isle, with the Kahului airport reporting a high temperature of 91F degrees, missing the record for the date by only 1 degree…which occurred back in 1953. At a little after 5pm, the airport was still reporting a very warm 87 degrees, while at the same time here in Kula, it was 75 degrees. The Haleakala Crater was measuring in with a much cooler 45 degrees. I’m sure that everyone can’t wait for the return of the trades, which will finally sweep this vog away…hopefully! I’ll be back again early Wednesday morning with your next new weather narrative, I hope you have a great Tuesday night wherever you’re spending it! Aloha, Glenn
