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’s Broad Brush Weather Overview…as of 345am Wednesday:  A breezy to windy trade wind pattern will persist through at least Wednesday, then gradually wane through the rest of the week. Moisture embedded in the trades will allow showers to favor windward and mountain areas. An overall wetter pattern is possible this weekend, as additional moisture is drawn over the island chain.

Hawaii’s Weather Details…as of 345am Wednesday:  A stationary 1037 millibar surface high is centered north-northeast of Hawaii. A stationary front is located 600 miles northwest of Kauai.  Winds continue to blow strong across the state at advisory levels (sustained speeds of 30-39 mph and/or gusts 50-57 mph) across portions of islands, especially over higher terrain, passes, and areas immediately south through west of mountains. A Wind Advisory goes through 6pm today for these portions of the state. By Thursday, winds will begin to decrease, but remain locally strong throughout the rest of the work week.

As far as precipitation is concerned, little change is expected over the next few days, with occasional showers and clouds embedded within the trades favoring windward and mountain areas over the next several days. Things begin to get a bit more interesting near the end of the week, as an overall pattern shift could ultimately lead to several days of wet and unstable trades this weekend into early next week.

Latest guidance remains in good agreement that southeast flow in the lower levels could expand moisture over the islands late this week, then stall it over the state for at least Saturday and Sunday. While it is still very early, this will be closely monitored for potential flooding, that could develop in this scenario. However, forecast confidence will largely depend on the expected strength of the trades, which will in turn modulate forward motion of showers.

The latest guidance continues to indicate that the islands could reside somewhere along the gradient between stronger trades to the east and light southeast flow to the west (though where exactly this sets up could make a large difference in rainfall potential for the islands). Still too early for specifics as there remains a lot of room for error, but something to continue monitoring throughout the rest of the week.

Hawaii’s Marine Environment…as of 345am Wednesday: Strong high pressure will remain far northeast of the state during the next couple of days, as a slow moving front approaches from the west. The front will stall out and weaken into a trough just a few hundred miles west of the islands this weekend, with a new high building in to the distant north. The trade winds and seas are expected to gradually lower Friday through the weekend.

Surf will hold relatively steady along east facing shores during the next couple of days, and as a result the High Surf Advisory (HSA) has been extended through 6pm Thursday. As the trade winds ease late in the week and over the weekend, surf along east facing shores will gradually lower below HSA thresholds.

Surf along north and west facing shores will remain well below seasonal levels through the weekend, and surf along south facing shores will remain very small.

Forerunners from a large, long-period north to north-northeast swell are forecast to arrive Sunday night, then rapidly build to advisory and potentially warning levels along north facing shores late Monday through Tuesday.

Interesting:  Even in Antarctica, Insects Are Eating Microplastics

Microscopic particles of plastic have been found across the Earth, from the clouds over Mount Fuji to the bottom of the Mediterranean Sea. Now, scientists have found microplastics in the bellies of Antarctic midges, the only insects found exclusively in Antarctica.

Microplastics are shed by synthetic fabrics and rubber tires, or by plastic bags, bottles, and other goods as they break down. Carried by winds or ocean currents, these plastic particles have been scattered across Antarctica and are now showing up in snow and seawater. There is some evidence that penguins and seabirds are consuming microplastics, and, according to a recent study, so are Antarctic midges.

For the study, researchers examined 40 midge larvae gathered from around the Antarctic Peninsula and analyzed the contents of their guts. While scientists detected just two plastic fragments in the dozens of larvae studied, they say the results are striking given that plastic pollution is so much scarcer in Antarctica than across the rest of the planet.
