Large monsoon swells are moving toward the Marianas and are expected to generate hazardous surf through at least Thursday morning.
Based on the information received from the National Weather Service in Tiyan, Guam, the high surf advisory is now in effect until 6am Thursday.
Surf will remain at hazardous levels of 8 to 11 feet along south-facing reefs and at hazardous levels of 11 to 14 feet along west-facing reefs through at least Wednesday. Surf heights could briefly reach 15 feet through today, Tuesday.
Surf will gradually diminish around midweek.
The high surf could produce localized beach erosion and dangerous conditions for swimmers and beach-goers.
The public is advised to avoid venturing out along south- and west-facing reefs and beaches. Large breaking waves can knock you down and cause serious injuries. Strong rip currents will be life threatening. (PR)
