Tropical Storm Lala at 8 PM continues to move west in offshore waters this evening located 190 miles west-southwest of Lihue. The Tropical Storm Warning for the coastal waters around Kauai has been replaced with a Small Craft Advisory (SCA). The current SCA now is for all waters around Maui County, Oahu and Kauai through 4 AM Monday. Marine conditions should gradually improve tonight through tomorrow as zones around Maui County and Oahu will likely get cancelled in the morning.
Large east-facing shore surf produced by Tropical Storm Lala has progressed westward across the state and is currently impacting Kauai and Niihau, where a High Surf Advisory remains in effect through midnight tonight. Surf will gradually fall below advisory levels overnight as Lala progresses further west of the state. North-facing surf will remain rough into this evening across the western end of the state as a result of this short period, Lala wind wave-driven chop in tandem with an east swell wrap.
South-facing shore surf will stay below advisory thresholds but remain elevated from a combination of lingering medium period south swell and Lala short period east swell through this evening. Longer period south swell energy generated from gales just south and east of New Zealand will begin arriving late this week.
