Update at 11:24 p.m. Nov. 5: The National Weather Service forecast office in Honolulu reports the heavy rain has ended and stream gauges are dropping around Kaua‘i.
Flooding is no longer expected to pose a threat, so the flood advisory that was previously in effect until 12:15 a.m. for the island has been canceled.
