Heavy rains keep crews busy over the weekend

Heavy rains pelted Oahu this afternoon and evening, resulting in several weather-related mishaps around the island.

In the 24-hour period ending at 7:45 p.m., the heavy rainfall was recorded at Manoa’s Lyon Arboretum (4.37 inches), Moanalua (3.92), Nuuanu (3.82) and Maunawili (3.74).

Around 12:20 p.m., Honolulu Fire Department personnel responded to an incident in which a vehicle spun out of control just outside the Kaneohe side of the Wilson Tunnel, where heavy rains had been detected. About an hour later, another vehicle traveling in the opposite direction spun out in the same area. No one was injured in either incident, according to HFD spokesman Capt. Kevin Mokulehua.

Around 7:14 p.m., HFD dispatched three units staffed by 11 personnel to a section of Palolo Stream near the intersection of Waialae Avenue and Koali Road, where two people were in need of assistance amid rain-swollen stream conditions.

Both were rescued from the stream without serious injury.

Less than an hour later, scanner transmissions indicated that three vehicles had struck a fallen tree in Nuuanu. No further details are yet available.
