Rain, wind, surf and flooding anticipated for Maui, other isles
Heavy rain, high surf, wind and flooding alerts for early this week have been posted by the National Weather Service.
A flash flood watch is in effect through Tuesday afternoon for Maui, Molokai, Lanai, Kahoolawe and Oahu, with heavy showers and isolated thunderstorms anticipated.
“Landslides may also occur in areas with steep terrain, especially along Maui’s Hana Highway,” forecasters said Sunday.
They warned of the possibility for “significant flooding” of streams, drainages and roads.
A storm front will move down the island chain and stall around Maui and the Big Island between Sunday and Monday, then drift back to Oahu and Kauai between Tuesday afternoon and Wednesday, the service said.
Also, strong northeast trade winds will follow.
A wind advisory is in effect until 6 p.m. Monday as north winds of 20 to 30 mph expected with localized gusts over 45 mph. The wind advisory covers Kahoolawe, Kauai, Lanai, Maui, Molokai, Niihau and Oahu.
“Winds this strong are capable of downing tents or other temporary structures, as well as downing trees and causing power outages,” forecasters said. “The strongest winds will occur over ridges and through valleys where winds can accelerate down-slope.”
The weather service also extended a high surf warning for much of the state as Saturday’s monster swell of 50-foot waves is replaced by a smaller, but still dangerous, northwest swell.
Surf of 30 to 40 feet is expected for north shores of Maui, Molokai, Niihau, Kauai and Oahu while 15-to-20 feet waves are predicted for west shores of Molokai, Niihau, Kauai and Oahu through Tuesday at 6 a.m.
