The National Weather Service canceled a flood advisory for Oahu on Wednesday after heavy but short-lived rains passed to the east. A weakening front is expected to move over Maui tonight then dissipate as it shifts to the Big Island later in the week.
At around noon, radar indicated heavy rain over Oahu, the NWS said. Residents and visitors were advised to stay away from streams and low-lying areas subject to flooding.
Multiple power outages were reported on Oahu. The Hawaiian Electric Co. outage map showed trouble spots around the island.
A flash flood warning for Kauai was posted then canceled Wednesday. County officials said in a news release that one lane is open to alternating traffic on Kuhio Highway near Hanalei Bridge. The highway had been closed earlier due to flooding. Drivers were advised to be careful in the area and allow for extra time because of slow-moving traffic.
The state Department of Transportation said on Twitter Wednesday night that Kailua-bound lanes of the Pali Highway have been reopened after a rock slide near the tunnels earlier in the day. Crews cleared debris and brought down loose material that potentially could have become loose.

A wind advisory for Oahu, Kauai and Niihau was also canceled.
Kauai and Niihau remain under a high surf advisory for south-facing shores until 6 a.m. Thursday.
The weather service issued a special notice earlier this week warning that coastal flooding is possible over the next few days along shores of all islands because of higher than normal tides.
Peak tides occur between midnight and daybreak for each day when the heaviest effects would occur. The high tides combined with potential for heavy rains and southerly winds could exacerbate flooding in low-lying areas and regions with poor drainage, the weather service said.
