Kauai and Oahu can expect some heavy rainfall Wednesday, although the weak low-pressure system that brought heavy showers and flash flooding Monday and Tuesday is moving westward and away from the islands.
Flash flood warnings, watches and advisories across the state were in effect at various times throughout Tuesday.
The National Weather Service extended a flash flood watch for most Hawaiian Islands until 6 p.m. Wednesday. The watch was canceled for Hawaii island overnight.
A flash flood advisory was in effect for Molokai and Lanai Wednesday morning until 9:45 a.m. and 9:30 a.m., repectively. According to radar estimates, Lanai City was drenched with between 2 to 4 inches of rain from 3:30 a.m. to 4:30 a.m.
Advisories for Kauai, Oahu and Hawaii island expired. The advisories were posted as heavy rain started hitting those islands about lunchtime Tuesday.
On Hawaii island, police reported Tuesday night that Route 190 between the 7 and 13 mile marker was experiencing heavy rainfall, ponding and fog. Motorists were asked to avoid the area due to hazardous conditions.
Windward Oahu from Waimanalo to Hauula was under a flash flood warning for part of the day Tuesday. “Windward Oahu got smashed about the same location” Tuesday in the Waiahole-Waikane area, where floodwaters were up to 2 feet deep Monday night, said National Weather Service meteorologist Henry Lau.
“The Big Island quieted down today,” Lau said.
