A few rumbles of thunder have been heard on Oahu as well. A Flash Flood Warning remains in effect until 915 PM to cover this ongoing event. Elsewhere across the state, scattered to numerous light to moderate showers prevail. Surface analysis shows a weak trough over the Northwestern Hawaiian Islands, with a strong high centered far to the NNE of the state. Brisk ESE flow prevails between these features over the islands. Aloft, a deep mid/upper level trough remains west of the state, with shortwaves evident in water vapor imagery rotating through the trough. MIMIC-TPW imagery and the 00Z soundings depict a very moist environment over and around the islands, with PW values ranging from 1.7 to almost 2 inches. Overnight, expect active weather to continue over Oahu and possibly Kauai, where the deep moisture in place is closest to the upper trough. Short-term radar trends suggest that the greatest risk for additional flooding during the next few hours may be over Oahu, and will need to look at expanding the Flash Flood Watch to cover Oahu for the rest of the night, as this current round of flooding may not be the last for this event. We have already updated the forecasts to keep mention of heavy rains and isolated thunderstorms through the remainder of the night for Kauai and Oahu. For Maui County and the Big Island, expect scattered to numerous showers but lower potential for any heavy rains or flooding. Models remain in good agreement with the weather pattern for the upcoming week, with a transition to drier and stable conditions expected. The upper trough to our west weakens during the next few days, while the blocking mid/upper level ridge that has been parked northeast of the state for the past several weeks shifts westward and closer to the islands. This will bring an increasingly stable airmass over the islands, with significant drying occurring in the mid levels. At the surface, east/southeast flow will continue between a persistent weak low pressure trough well to our west and strong high pressure to our northeast. It appears that winds will remain easterly enough to prevent blocking by the Big Island of the smaller islands, so expect trade winds to become strong and gusty in many areas by midweek. Downsloping effects may allow the winds to be strong enough to require Wind Advisories for some areas. As for rain chances, Monday looks like a transition day with trade winds taking hold and shower intensity diminishing during the day. Some heavier showers will remain possible over the western end of the state, especially in the morning. Models show a drier airmass moving in from the northeast on Tuesday, with PW values dropping to around one inch. Thereafter, expect a strong trade wind pattern, with passing showers focused over windward and mauka areas. The strength of the trades will allow some showers to spill over leeward. && .AVIATION... High pressure far NE of the area and a broad surface trough W of Kauai, will keep locally strong E to SE winds over the islands tonight. The trough of low pressure will shift westward on Monday, allowing a more typical easterly trade wind regime to overspread the island chain. Widespread MVFR cigs/vsbys are expected to continue over windward areas of Kauai Oahu Molokai Maui and the Big Island overnight, with conditions improving in most areas around mid morning Monday. Conditions will be a bit more unsettled across Oahu and Kauai at least through the evening, with the potential for heavy rainfall and thunderstorms, along with MVFR cigs/vsbys even in leeward areas. AIRMET Sierra remains in effect for mountain obscuration across Kauai and Oahu, and for windward sections of Molokai, Maui, and the Big Island. These conditions will likely continue through mid morning Monday, although leeward sections of Kauai and Oahu may improve later tonight. AIRMET Tango remains in effect for low level turbulence due to strong east to southeast winds, and this AIRMET will likely continue through Monday. AIRMET Tango also remains in effect for moderate upper level turbulence for the entire island chain and will likely continue through Monday as well. AIRMET Zulu remains in effect for moderate icing over Kauai and Oahu. These conditions will likely improve later tonight. Light icing is also mentioned for the remaining islands. && .MARINE... A very moist and unstable air mass will maintain a threat of thunderstorms across the western half of the state through early Monday morning. Mariners should be alert for reduced visibilities in heavy downpours, locally gusty and shifting winds, increased seas and frequent lightning in the vicinity of any thunderstorms that develop over the ocean. A Small Craft Advisory (SCA) remains posted through Tuesday afternoon for most waters, including all windward areas, due to strong east-southeast winds and elevated rough seas. The east- southeast winds are forecast to strengthen Tuesday. As a result, gale conditions are possible over some waters adjacent to the islands of Maui County and the Big Island starting Tuesday. The winds may be near gale force over these areas through mid-week. Otherwise, expect SCA conditions to prevail over most waters through Friday. A long and relatively broad fetch of strong easterly winds along the southern flank of the circulation around a large subtropical high over the northeast Pacific will continue to produce a large east swell this week. This east swell is generating elevated surf along east facing shores. Therefore, a High Surf Advisory (HSA) remains in effect for most east facing shores through Monday afternoon. The strengthening winds upstream of the state will cause the east swell to build. Therefore, surf may reach the High Surf Warning criteria along east facing shores starting Monday night or Tuesday. This elevated surf will likely continue into next weekend. The long duration of this large surf combined with strong onshore winds and large astronomical tides will likely result in coastal inundation, especially during the highest tides, along some vulnerable low lying sections of the east facing shorelines later this week. Small northwest swells are forecast to keep surf well below normal along most north and west facing shores this week. The east swell energy wrapping around to some select north and south facing shores may produce localized bumps in surf heights along some exposed northern and southern beaches across the island chain. && .HFO WATCHES/WARNINGS/ADVISORIES... Flash Flood Watch until 6 AM HST Monday for Niihau-Kauai. High Surf Advisory until 6 PM HST Monday for east facing shores of Kauai Oahu Molokai Maui and the Big Island. Small Craft Advisory until 6 PM HST Tuesday for Kauai Northwest Waters-Kauai Windward Waters-Kauai Channel-Oahu Windward Waters- Kaiwi Channel-Maui County Windward Waters-Maui County Leeward Waters-Pailolo Channel-Alenuihaha Channel-Big Island Windward Waters-Big Island Leeward Waters-Big Island Southeast Waters. && DISCUSSION...Jacobson AVIATION...Jelsema MARINE...Houston
