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 319pm 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 319pm Wednesday:  At the surface, strong high pressure remains centered north-northeast of the islands, with a front located northwest of Kauai. Winds across the state are at or very near advisory levels, which are sustained speeds of 30-39 mph and/or gusts 50-57 mph, especially over higher terrain, passes, and areas immediately south through west of mountains. Latest observations show that the strongest gusts have occurred over the typically windier locations of Molokai, Maui County and the Big Island, with Gales in the windier waters and channels surrounding Maui County and the Big Island.

A mid-level dry airmass will remain in place in support of a strong inversion. Gradient winds are expected to remain nearly unchanged as the surface high remains to our north, and the front remains nearly stationary to our west. Based on this, the Wind Advisory has been extended in time through 6am Thursday. By Thursday afternoon, winds will begin to slowly decrease, but still remain locally strong throughout the rest of the week.

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

Latest guidance remains in good agreement that moist southeast flow in the lower levels could expand moisture over the islands this weekend, then stall it over the state into Sunday. This is being closely monitored for potential flooding that could develop in this scenario. Forecast confidence will largely depend on the expected strength of trades, which will in turn modulate forward motion of showers.

Guidance indicates that the islands could reside somewhere along the gradient between stronger trades to the east, and light southeast flow to the west (where exactly this sets up could make for a large difference in rainfall potential for the islands). Still too early for specifics and what impacts we will face. Please continue to monitor forecasts in the coming days as details begin to iron out.

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.
