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.

It’s mostly clear here in Maui County early this morning, although with some streaky high cirrus clouds…with a low temperature of 52.5 degrees at my place.

Hawaii’s Broad Brush Weather Overview: Bands of low level clouds with embedded showers will focus mainly along windward and mountain areas as moderate trades hold into Monday. Winds will become light and veer southerly Tuesday, as a front approaches the state from the northwest. The front is expected to move over the state during the second half of next bringing a wetter period.

Hawaii’s Weather Details: Latest surface analysis shows a trough of low pressure west of Kauai, where some isolated thunderstorms are being triggered just outside of the coastal waters. This trough is expected to weaken and lift north today, keeping the threat of thunderstorms west of the coastal waters. Overnight rainfall totals on Kauai range from 0.06 to 2.00 inches for the wetter regions of Kauai. Expect showers to trend down during the day as a drier airmass with limited upstream clouds and showers moves through.

Moderate trades will ease slightly tonight as an upper level trough moves overhead. This slight instability overnight could help provide isolated moderate to locally heavy rainfall, but should be brief and mainly focused along windward and mountain areas. The exception could be the Kona slopes of the Big Island, as sea breezes strengthen this afternoon into the early evening hours.

The upper level trough will continue to dig southeast of the state through Sunday, and eventually form a closed low east of the state Monday. This pattern should place the state in an area of subsidence as low to mid level ridging builds in from the west, creating a highly stable, moderate trade wind pattern. Some bands of low level clouds and showers trapped within the trade wind flow, enhanced by the upper low, will mainly focus along windward and mountain areas.

Extended guidance continues to show a cold front approaching the state from the northwest Tuesday, allowing winds to become light to gentle and veer southeast. Details on the timing and exact impacts as the front moves through the state are still unknown. The EC model brings the front in Wednesday night, with more modest impacts than the GFS, which brings the front in around Thursday morning with stronger frontal lift, and upper level dynamics resulting in a wetter pattern.

Fire weather: The inversion slopes from around 7,000 feet at Lihue to 11,000 feet at Hilo. A slightly drier airmass has filtered in, but moderate trades are unlikely to reach the critical fire threshold and will ease slightly tonight. Light southeast winds are expected Tuesday preceding a wetter weather pattern during the middle to second half of next week.

Hawaii’s Marine Environment: A surface trough west of Kauai will continue to weaken and drift slowly westward away from the islands through Sunday. A surface high pressure ridge will remain north of Hawaii, winds flowing around this ridge will produce moderate to locally strong easterly trade winds today, then wind speeds will slowly decrease Sunday onward.

Lighter southeast to south winds are forecast from Tuesday to Wednesday as another cold front moves into the region from the northwest. A consensus of weather model guidance suggests this cold front may move into the western Hawaiian islands from late Wednesday into Thursday.

A Small Craft Advisory (SCA) remains in effect for the typically windier waters around the islands in Maui and Hawaii Counties. Trade winds will drop below SCA thresholds by tonight.

The current medium period north-northwest (340-350 degree) swell continues to slowly decline. Buoy observations from National Data Buoy Center stations 51001 and 51101 just northwest of Kauai show a gradual downward trend. The latest swell model guidance confirms this downward trend as the current north-northwest swell energy will gradually fade into Monday, bringing surf back down to below average levels for this time of year. The next two long to medium period overlapping northwest (310-320 degree) swell pulses will arrive on Monday and Tuesday, boosting surf along north and west facing shores, possibly reaching marginal advisory levels by Wednesday.

Choppy east shore surf will remain small and decline this weekend as trades ease. Expect minimal background energy for south facing shores through the next few days, other than a slight rise this weekend.

Peak monthly tides combined with water levels that are running higher than predicted will likely lead to minor flooding along the shoreline and in low-lying coastal areas. Coastal flooding is possible around the early morning peak tide through Sunday.

Interesting:  Hurricane Season Ends, But Weather Woes Push Floridians to Move

Although the Atlantic hurricane season has officially ended, Floridians’ woes over severe weather and soaring homeowners’ insurance costs still linger. A new Florida Atlantic University survey finds hurricanes and other climate-related threats are causing many Floridians to consider moving.

The Florida Climate Survey found that 36% of respondents statewide had moved or were considering moving in part or fully due to weather hazards. Broken down by region, the results show that threats such as hurricanes, flooding and extreme heat have already influenced some Floridians to relocate.

Nearly a quarter of North Floridians (24%) reported that these factors contributed to a previous decision to move within the state. Across much of the peninsula, from Tampa to Cape Canaveral south, about 20% of respondents report that weather hazards play a role in them exploring a move.
