Description
What
Large breaking waves of 7 to 9 feet expected in the surf zone. Dangerous rip currents expected.
Where
North facing reefs of the Marianas.
When
Until 4 AM ChST Saturday.
Impacts
Dangerous swimming and surfing conditions and localized beach erosion. Rip currents can sweep even the best swimmers away from shore into deeper water.
Additional details
An elevated, long-period north swell is producing hazardous surf up to 9 feet and a high risk of rip currents along north-facing reefs. Observation sites have reported surf up to 7 feet with frequent, larger sets of 7 to 9 feet already occurring along some north-facing reefs. Swimming conditions will be dangerous at least through late Friday night before surf falls below hazardous levels of 9 feet shortly afterwards.
Instructions
Rip currents will be life threatening. Inexperienced swimmers should remain out of the water due to dangerous surf conditions. Rip currents will be life threatening. If caught in a rip current, relax and float. Don't swim against the current. If able, swim in a direction following the shoreline. If unable to escape, face the shore and call or wave for help.
