High Surf Warning — Waianae Coast; Kahoolawe; Maui Leeward West; Kona; East Honolulu; Honolulu Metro; Ewa Plain; Molokai Southeast; Molokai West; Molokai Leeward South; Lanai Leeward; Lanai South; Maui Central Valley South; Kipahulu; South Maui/Upcountry; South Haleakala; Big Island South; Big Island Southeast
Severity: Moderate. Certainty: Likely.
...HIGH SURF WARNING FOR SOUTH FACING SHORES OF ALL ISLANDS
THROUGH MONDAY NIGHT...
...HIGH SURF WARNING FOR WEST FACING SHORES OF BIG ISLAND THROUGH
MONDAY NIGHT...
...HIGH SURF ADVISORY FOR EAST FACING SHORES OF ALL ISLANDS
THROUGH MONDAY NIGHT...

.South swell from Hurricane Lowell is expected to rise rapidly
Monday, and peak Monday night bringing warning level surf to
exposed shorelines. This swell may shift out of the southwest
late Monday night. Due to the track of Lowell, a sharp gradient
in swell is expected from west to east. This will bring damaging
surf to portions of Kauai County and possibly Oahu. Swell energy
is expected to drop off quickly on Tuesday.

A large, medium-period east swell from Tropical Storm Karina will
also persist through at least Monday, producing advisory level
surf along east facing shores.

* WHAT...Surf of 7 to 10 feet through Monday morning, rapidly
building Monday afternoon and evening up to 12 to 20 feet on
Oahu and 12 to 16 feet on Maui County and the Big Island.

* WHERE...South facing shores of Kahoolawe, Lanai, Maui, Molokai,
Oahu and the Big Island.

* WHEN...Until 6 AM HST Tuesday.

* IMPACTS...Very High...Expect ocean water surging and sweeping
across beaches, coastal benches, and lava flows creating the
potential for impacts to coastal properties and infrastructure,
including roadways. Powerful longshore and rip currents will be
present at most beaches. Large breaking waves and strong
currents may impact harbor entrances and channels causing
challenging boat handling.
