Hawaii’s MountainsHere’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.

Glenn’s Saturday comments:  I’m here at home in upper Kula, Maui

It’s mostly cloudy here in Maui County early this morning, and I just had a light shower, with a low temperature of 59 degrees at my place, with the relative humidity 80 percent.

1216pm, it’s turned cloudy and a bit foggy here in upper Kula, with a very light sprinkle.

115pm, it’s very voggy here in Maui County this afternoon.

506pm, it’s still very voggy, although the local clouds over Maui remain not showery, at least at the time of this writing.

842pm, skies have cleared up for the moment, although satellite images show more high and middle level clouds moving towards Maui County. Due to the clear skies the temperature has dropped to 59.1 degrees, with the RH  70%

Interesting Web blog: Mauka Showers – Recap – Our First Big Rain Event of the Wet Season

 

Hawaii’s Broad Brush Weather Overview: A few heavy showers and thunderstorms may linger across Kauai and Oahu. Trade winds are expected to build tonight becoming breezy Monday and Tuesday.

Hawaii’s Weather Details: A few heavy showers and thunderstorms may linger across Kauai and Oahu, as the system that brought heavy rain across much of the state begins to fade. Light and variable winds will shift easterly and strengthen tonight and Sunday, eventually becoming breezy by Monday.

Scattered to broken high clouds will continue across the area through Sunday. Upper ridging over the islands will keep an active system west of us over the next several days, but occasional high clouds may come in over the western half of the state into the new week.

A stationary front north of the islands will dissipate with trade winds overrunning it, carrying the remnant moisture band over the islands Monday and Tuesday. Otherwise, trades will focus clouds and showers over the typical windward and mountain areas, with breezier and wetter days (Monday and Tuesday) forcing more of the showers leeward.

Drier trade winds are expected Wednesday and Thursday, before winds begin to veer east-southeast on Friday through next weekend…ahead of the next early winter cold front.

Fire weather:  Conditions are expected to remain below critical fire thresholds over the next several days. Showers and generally high relative humidities will be accompanied by light southerly winds, that will transition to trade winds over the next couple of days.

Hawaii’s Marine Environment: A lingering unstable airmass will lead to another round of scattered showers and isolated thunderstorms over the western coastal waters with a light and variable wind flow. Gentle to locally moderate southeasterly winds will prevail across the eastern waters with less shower activity.

By late this weekend, easterly trade winds will gradually strengthen with the potential for SCA conditions over the windier waters and channels around Maui County and the Big Island. Expect trades to become even stronger early to mid next week, as surface high pressure builds to the north.

Two overlapping small to moderate, medium period, northerly swells (350 deg) and (010 deg) will dominate through the remainder of this weekend, and bring elevated surf to north facing beaches. However, surf should stay just shy of High Surf Advisory criteria, and combined seas will remain below Small Craft Advisory criteria. Late Sunday through mid next week, north swell energy fades which should allow surf to drop to below seasonal averages.

Surf along east facing shores will remain small given the lack of trade winds upstream of the islands, but areas exposed to the north swell will see an increase. As trade winds gradually strengthen late Sunday through early next week, east facing shores could become rough and choppy. Surf along south facing shores will remain flat to tiny through the weekend into early next week.

Interesting: Researchers Find Trees Could Spruce Up Future Water Conservation Efforts

Trees contain valuable information about Earth’s past, so much so that studying their rings may help fill in hidden gaps in Ohio’s environmental history.

Trees are the planet’s living lungs; they remove carbon from the atmosphere to clean the air, and filter our water. Yet depending on their species, not all record long-term environmental changes, such as fires, floods and droughts, in the same way.

By analyzing how various types of tree rings grow in response to these distinct weather-related events, researchers discovered that some can act as useful tools in managing local watersheds, that drain water into nearby streams and rivers.
