Guam – The National Weather Service in Tiyan is warning of dangerous surf throughout the Mariana Islands this weekend.
The Weather Service has issued a High Surf ADVISORY for Guam and Rota, and a WARNING has been declared for Tinian and Saipan.
The Advisory and Warning go into effect at 4am TODAY, Friday January 24, and they are scheduled to remain in effect until Noon next Tuesday, January 28.
The Weather Service says the cause is a strong cold front that is moving southeastward from Japan toward the Marianas. The NWS says that “gales on the north side of the front will generate very large and dangerous long period swells.”
In the CNMI the surf could rise as high as 19 feet by Saturday night and up to 14 feet on Guam.
The NWS advises residents to avoid venturing near exposed reefs and beaches, especially those along north facing reefs because surf this high will generate dangerous rip currents which are life threatening.
In addition, the national Weather Service has also issued a Small Craft Advisory which will also take effect at 4pm TODAY, Friday Janaury 24th, and remain in effect until 6pm SUNDAY.
