The local office's own words before the first event, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Honolulu, HI wrote its last area forecast discussion before the first event at Jan 31, 9:02 PM HST, 2 hours 58 minutes earlier.
Area Forecast Discussion...CORRECTED National Weather Service Honolulu HI 902 PM HST Fri Jan 31 2025 .SYNOPSIS... Residual moisture around a diminishing front in the vicinity of the central islands has continued to bring showers to parts of the islands, mainly over portions of Maui County and the Big Island. Drier conditions return with northwesterly winds, gradually transitioning northerly over the weekend. As the work week begins, a more typical northeast trade wind pattern is anticipated to return, with showers favoring windward and muaka areas through the early part of next week. However, trades weaken towards the end of the week in response to a passing mid-level troughing. && .DISCUSSION... Latest satellite imagery shows some showers continuing across many portions of the islands, moving southwest to northeast, with the strongest showers over Moloka'i from a diminishing frontal passage. This has resulted in a flood advisory being issued for the aforementioned area through 10:45 local time due to the excessive rainfall. These showers will continue through the evening and into the morning hours before moving southeastward into the eastern regions of the Big Island. Additionally, latest webcams show moderate snowfall accumulating over the summits above 12,000 ft of Mauna Kea and Mauna Loa. This will also continue through the overnight hours along with periods of gusty winds, and decreasing thereafter. Stable, breezy winds become established from the northwest as a weak area of transitioning to a more northern component over the weekend. Conditions will also be much drier for most of the island through the weekend, with only lingering showers over the Big Island, predominately over the Hamakua coastline. As we move into next week, trades are reintroduced to the forecast, courtesy of the building high pressure over the Central Pacific Basin just west of the islands. However, late week mid-level troughing passes over the islands, resulting in weakened trades. && .AVIATION... Clouds and spotty showers favoring SW through N facing slopes will linger overnight and into early Saturday, due to moderate west-southwest flow and some residual moisture lingering around a diminishing front. Expect a gradual drying trend from west to east through the 24 hr period, with the low-level flow gradually veering from the WSW to the N through the day Saturday. AIRMET Sierra for tempo mountain obscuration is in effect for SW thru N facing slopes, which may persist through a good portion of the night before improving. && .MARINE... A strong low passing to the north of the state will continue its slow northeastward march. Its associated cold front is presently passing over Oahu and moving steadily eastward --weakening in the process. Bands of showers, preceding the front, will persist over the eastern half of the sate through Saturday night. Showers may be heavy at times, but additional thunderstorms are not expected. By Saturday morning, the front is expected to be near the Big Island with gentle to moderate NW winds expected over most of the state on Saturday. High pressure building far NW of the state should bring the return of moderate northerly trades on Sunday veering slightly more easterly and strengthening to locally strong speeds by Monday afternoon into Tuesday. Multiple overlapping north and northwest swells associated with the storm will continue to impact Hawaii through the remainder of the weekend. A Small Craft Advisory (SCA) is in effect through 6 am Saturday for many zones due to seas of 10 feet or greater. While seas are expected to subside somewhat overnight, the SCA will likely need to be extended through Saturday afternoon for select zones. A High Surf Advisory (HSA) remains in effect for north facing shores of Niihau, Kauai, Oahu, Molokai, and Maui, but will likely be cancelled towards morning. The current long-period north (010) swell is expected to quickly subside and a medium- period northwest (310) swell become dominant by Saturday afternoon. Locally generated wind waves out of the south and west will keep surf rough along west and southwest shores through Saturday. Another significant north swell is expected to build in during the day Sunday, peak Sunday night, and possibly generate advisory level surf along north facing shores. An additional northwest swell is also expected. This swell will arrive on Monday, peak on Tuesday, and linger through Wednesday, but should not produce high surf. && .HFO WATCHES/WARNINGS/ADVISORIES... High Surf Advisory until 6 AM HST Saturday for Niihau-Oahu North Shore-Maui Windward West-Kauai North-Molokai Windward-Molokai North-Maui Central Valley North-Windward Haleakala. Wind Advisory until 6 PM HST Saturday for Haleakala Summit. High Wind Warning until 6 AM HST Saturday for Big Island Summits. Small Craft Advisory until 6 AM HST Saturday for Kauai Northwest Waters-Kauai Windward Waters-Kauai Leeward Waters-Kauai Channel- Oahu Windward Waters-Oahu Leeward Waters-Kaiwi Channel-Maui County Windward Waters-Big Island Windward Waters. && DISCUSSION...Pierce AVIATION...Gibbs MARINE...Bedal
