Hawaii’s Mountains – Here’s a link to the live webcam on the summit of our tallest mountain Mauna Kea (~13,800 feet high) on the Big Island of Hawaii. Here’s the webcam for the (~10,023 feet high) Haleakala Crater 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.

Interesting Weather Blog: Mauka Showers…Hawaii Rainfall Patterns During Recent El Niño Events

 

Hawaii’s Weather Highlights…as of Sunday morning: A strong high pressure system will build north of the Hawaiian Islands today on a slow eastward drift. Strong gusty winds will develop over and down stream of island mountain ranges today. Wind speeds will exceed advisory thresholds in the windier areas of all islands except for Kauai and Niihau. Passing showers are possible over windward and mountain areas through much of the upcoming week, with higher rainfall amounts favoring the overnight to early morning hours.

Weather Narrative…as of Sunday morning: A combination of satellite and radar imagery shows unsettled cumulus clouds riding in on the trade winds, producing periods of rain showers across much of the state. Higher rainfall amounts will favor windward mountain areas of all islands, especially in the overnight to early morning hours.

Upper air weather balloon soundings from Lihue and Hilo observed subsidence temperature inversion heights around 6,000 feet, high enough for periods of passing showers to remain in the forecast. Stronger low level winds will also help to lift unstable clouds up over island mountains, forcing enhanced rainfall activity.

A satellite scatterometry pass from last night, measuring wind speeds through microwave scattering of wind blowing over the ocean water, reported near Gale Force winds in the Kaiwi and Alenuihaha channels. This satellite wind report and the forecast for increasing winds through the day, led to Gale Warnings for the windiest channels, and Wind Advisories for windier land areas over and down wind of island mountain ranges from Oahu eastward to the Big Island of Hawaii. Kauai and Niihau will likely remain just below Wind Advisory thresholds today.

Enhanced showers will likely continue through much of this week. Initially, we see a low level cloud band moving across the islands from the north Monday afternoon into Tuesday. Then a passing weak upper low tracks from west to east across the islands on Wednesday and Thursday lifting cloud heights, and finally we see yet another low level cloud band riding into the islands on the trade winds by Friday.

In essence, these passing weather systems will keep periods of enhanced showers in the forecast into next weekend. Light to moderate beneficial rainfall amounts are expected in this weeks wet trade wind weather pattern.

Fire Weather: Strong winds will develop today for most higher elevation mountain areas. Relative humidity levels in these areas will remain above critical fire weather thresholds. Wet weather conditions will also help to mitigate fire threats by increasing humidity levels in lower elevation areas. Temperature inversion heights near Maui and the Big Island will range from 6,500 to 7,500 feet elevation today.

Marine Conditions…as of Sunday morning: Strong trade winds expected today as a strong high builds far north of the islands. Some zones have been upgraded to a Gale Warning today, with the remaining coastal waters in the Small Craft Advisory (SCA). Winds will diminish gradually tonight and Monday as the high moves to the northeast, but a new north swell will push combined seas above 10 feet for exposed waters, likely prompting an extension of the SCA for most zones. Expect moderate to locally strong trade winds to require a SCA for the typically windy waters Tuesday through the remainder of the upcoming week.

A moderate, long-period north swell will build today and produce surf near High Surf Advisory thresholds along north-facing shores, as well as some exposed eastern shores into Monday morning. The north swell will gradually decline late Monday through Wednesday. A tiny pulse of northwest swell will be possible late in the week, followed a moderate swell next weekend.

Rough surf along east-facing shores will remain above seasonal average over the next couple of days, due to elevated trade wind swell and some wrapping north swell. East shore surf is expected to be around seasonal average Tuesday through the rest of the week. Mainly small background level surf will persist along south- facing shores through much of the week, though a small long- period swell will be possible on Friday.

Oahu Infrastructure Threatened by Tipping Point in Sea-Level Rise Impacts

A new comprehensive study by researchers at the University of Hawaii (UH) at M?noa Climate Resilience Collaborative reveals that traditional sea-level rise models, that account only for rising ocean waters, drastically underestimate the true threat to coastal infrastructure on Oahu, Hawaii. By incorporating shoreline erosion and high-wave events, in addition to rising sea levels, researchers found that current single-hazard projections overlook up to two-thirds of threatened land area on and up to 85% to 100% of critical infrastructure, such as buildings, roadways, and cesspools, that are likely to be impacted.

“This tells us that it is critical to use multiple hazard models, and that areas with little data, such as other Pacific Islands, that rely on simpler passive flood model estimates may be underestimating the risk to their coastal infrastructure,” said Anna Mikkelsen, lead author and graduate student in the Department of Earth Sciences in the UH M?noa School of Ocean and Earth Science and Technology (SOEST).

The study updates previous sea-level rise vulnerability estimates for Oahu using high-resolution interagency climate projections. Researchers overlaid three advanced physical models—accounting for flooding from rising water levels, shoreline erosion, and annual high wave events—onto maps of buildings, parcels, roads, schools, hospitals, parks, wastewater infrastructure, and resident population.
