.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 6 to 8 feet through Monday morning rapidly
building Monday afternoon and evening to 12 to 16 feet.
* WHERE...West facing shores of the Big Island.
* WHEN...Until 6 AM HST Tuesday.
* IMPACTS...High. Expect very strong breaking waves and powerful
currents. Waves breaking in channel entrances may make
navigating the channels dangerous.
