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 170703 AFDHFO
Area Forecast Discussion National Weather Service Honolulu HI 903 PM HST Thu May 16 2024
SYNOPSIS
A kona low north of the state will continue drawing unstable tropical moisture northward over the islands into Saturday. Bands of showers producing moderate to heavy rain and isolated thunderstorms will move over the central and western islands tonight through at least Friday. The kona low will begin to drift away from the state this weekend with improving trends spreading from east to west. Enhanced rainfall may linger over Kauai and Niihau into Sunday. By Monday all islands will see a dramatic improvement in weather conditions as easterly trade winds return.
DISCUSSION
A kona low northwest of the Hawaiian Islands will continue to produce periods of moderate to heavy showers across portions of the central and western islands through at least Friday. Satellite and local radar imagery this evening continue to show a large band of moderate to heavy showers currently over Oahu. Rainfall rates under this band are falling around 1 inch per hour. The highest 24 hour rainfall totals over Oahu have reached from 8 to 10 inches in some locations. A Flood Watch remains in effect for the western and central islands through Friday.
Impacts through Saturday...Periods of moderate to heavy showers with the potential for isolated thunderstorms will continue mainly over Oahu tonight and possibly Molokai and Lanai. This shower activity will then shift towards Kauai on Friday with additional bands of showers moving over Oahu. The main flooding threat will be from bands of showers that line up and train over any one location, as several hours of 1 to 2 inch rainfall rates can add up fairly quickly, especially over already saturated ground. By late Friday the low will begin to drift farther north, moving away from the islands, and allowing the subtropical ridge to build back in north of the state. Expect more stable conditions with decreasing showers as east to southeast winds spreading across the state from east to west this weekend.
Sunday through Wednesday...By Sunday the moderate to heavy rainfall threat will linger over Kauai as more stable conditions move in across the state. Easterly trade winds return from Monday onward with only brief passing showers in the forecast through the middle of next week.
AVIATION
A strong kona low NNW of Kauai is pulling tropical moisture out of the south across the state. Moderate to heavy rain showers and isolated embedded thunderstorms are expected over the western side islands into Saturday. On the Big Island, shower activity will taper off during the nighttime hours only to redevelop during the afternoons and early evenings.
Latest radar imagery reveals the heaviest showers over Oahu and the Kaiwi channel. This band is expected to slide westward. By tomorrow afternoon, the heaviest showers will likely be over Kauai and Kauai Channel.
AIRMET Sierra is in effect for for mtn obsc for Kauai, Oahu, Molokai, Lanai, Maui and windward Big Island and for IFR conds over Oahu, Molokai and Lanai.
AIRMET Tango is in effect for turb blw 120 N thru E of the Big Island.
Occasional light rime icing is expected from Kauai to Maui 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 Friday. 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). 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 later Friday).
Surf along south facing shores will remain up through early next week due to overlapping, long-period south-southwest swells expected. The first swell filled in through the day today and will peak tonight through Friday, likely holding at the advisory level. Observations at the offshore buoys 51003 and 51004 (51002 remains down) reflect this with the long-period peak energy shifting into the 15-19 second bands. Expect rough conditions for most southerly exposures through this period 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 Friday. As this swell slowly eases over the weekend, a fresh, long-period south-southwest swell will begin to fill in through the day Sunday. This will peak at a similar level early next week before easing through midweek.
Surf along north and west facing shores has trended up through the day due to a short-period northwest swell generated from the nearby kona low. This swell will linger Friday (largest Kauai), then ease 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 Friday evening for the islands of Kauai, Niihau, Oahu, Molokai and Lanai.
High Surf Advisory until 6 PM HST Friday for south facing shores.
Wind Advisory until 4 AM HST Friday for Big Island Summits.
Small Craft Advisory until 6 PM HST Friday for Big Island Windward Waters-Big Island Leeward Waters.
