Synopsis for hawaiian coastal waters - A kona low will remain far northwest of the area into the weekend, then slowly lift northward and away from the region Sunday through early next week.
FXHW60 PHFO 180150 AFDHFO
Area Forecast Discussion National Weather Service Honolulu HI 350 PM HST Fri May 17 2024
SYNOPSIS
A kona low north of the state will continue drawing unstable tropical moisture northward over Kauai County through Saturday.
The kona low will begin slowly drift away from the state this weekend with improving trends spreading from east to west, though enhanced rainfall may linger over Kauai and Niihau through Saturday night. By Monday all islands will see an improvement in weather conditions as easterly trade winds return.
DISCUSSION
A kona low remains centered roughly 750 nm northwest of Kauai.
Meanwhile, a decaying front in the Kauai Channel will transition to a trough this evening. This feature is serving as the dominant focus for showers and isolated thunderstorms late this afternoon, where recent radar trends show that nearly all of the moderate to heavy rainfall is now occurring over the Kauai Channel. Similar to yesterday, afternoon convection on the Big Island has sparked a few upslope showers and even isolated thunder this afternoon, but this convection has been weaker and more transient than yesterday.
The band of showers over the Kauai Channel will gradually move westward this evening, reaching Kauai County where a Flood Watch remains in effect and has been extended through late Saturday night. With this afternoon's forecast updates, the watch has been cancelled for the island of Oahu as the band has progressed farther west. While showers will still be possible at times for Oahu, model guidance suggests that the heavy rain threat will be focused over the Garden Isle through the first half of the weekend. The main consideration for the island of Kauai will be how long the band lingers over the island before moving off to the northwest as the kona low exits the region. While consensus is that conditions will begin to improve Saturday night, the flooding concerns could linger a bit longer should this be a slower transition. Models also are still hinting that one last moisture surge back towards Oahu is possible on Saturday night, but confidence remains low in this occurring at this time.
High pressure will slowly build into the region this weekend as the kona low exits the pattern to the north. Expect more stabilizing trends with decreasing showers as east to southeast winds spread across the state. Likely by Sunday, the moderate to heavy rainfall threat will diminish over Kauai as more stable conditions fill in across the state.
More typical easterly trade winds will return across the state from Monday onward with only brief passing showers in the forecast favoring the typical windward and mountain areas through the middle of next week.
AVIATION
A moist and unstable cloud band associated with a kona low far to our northwest is currently over the waters between Oahu and Kauai and approaching Kauai. This cloud band will bring MVFR with embedded IFR conditions to Kauai through tomorrow morning. Winds should remain out of the south- southeast through tomorrow.
Lingering moisture could still bring short periods of MVFR conditions to any of the islands tonight and primarily focus over the southeast facing slopes.
AIRMET Sierra is in effect for Kauai, Oahu, and windward Big Island. IFR cond over Kauai will likely persist through tomorrow morning as the rain band lingers. Mountain obscuration could remain over Oahu tonight if low clouds persist.
AIRMET Tango is in effect for low level mechanical turbulence north through east of the Big Island and East Maui. Also upper level turbulence could be a possibility tomorrow morning.
Occasional light rime icing is expected from Kauai to Oahu in layer 140-FL250.
MARINE
Fresh to locally strong south to southeast winds associated with a kona low north-northwest of the state will persist through tonight. A shift out of the east to southeast direction is expected over the weekend through early next week as it lifts northward and away from the area. A Small Craft Advisory remains in effect for the Windward and Leeward Big Island waters (Hamakua Coast and waters near South Point) through tonight. In addition to the winds, expect locally rough seas in heavy showers or storms that develop, with the best chances being over the waters west of Maui County. Seas should remain just below the advisory level over the exposed Kauai waters as a short-period northwest swell moves through (downward trend expected this weekend).
Surf along south facing shores will remain up through early next week due to overlapping, long-period south-southwest swells. The first swell is peaking today and will hold at the advisory level into tomorrow before briefly lowering. Expect rough conditions for most southerly exposures today due to a combination of the onshore winds, swell, and periodic heavy showers moving through.
As a result, a High Surf Advisory remains in effect through Saturday. A fresh, long- period south-southwest swell will fill in through the day Sunday, then peak at a similar level early next week before easing through midweek.
Surf along north and west facing shores will remain up into Saturday due to a short-period northwest swell generated from the kona low. This swell will lower over the weekend.
Surf along east facing shores will remain well below average through the weekend. An upward trend is possible next week as the trades return locally and far upstream over the eastern Pacific.
HFO WATCHES/WARNINGS/ADVISORIES
Flood Watch through late Saturday night for Niihau and Kauai.
High Surf Advisory until 6 PM HST Saturday for south facing shores of all islands.
Small Craft Advisory until 6 AM HST Saturday for Big Island Windward Waters-Big Island Leeward Waters.
