...HIGH SURF ADVISORY FOR SOUTH AND EAST FACING SHORES THROUGH
MONDAY NIGHT...

South and southwesterly swells from Hurricane Lowell will keep
surf elevated above High Surf Advisory conditions across south-
and west-facing shores through Monday night. The northward turn
Lowell is currently executing will cause a rapid increase in
swell, likely bringing surf along some of these shores to warning
levels on Monday. These swells are then 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.
