* IMPACTS...Some water on low lying roads and property. Breaking waves can sweep people off jetties and docks, and into dangerous seas. Life-threatening swimming conditions and significant beach erosion can be expected. Rip currents can sweep even the best swimmers away from shore into deeper water.
* ADDITIONAL DETAILS...As TY In-fa moves west-northwest toward the far northern CNMI, seas are expected to rapidly increase dueto the large, long-period northeast swell emanating from In-fa. This has begun to produce dangerous surf along north and east facing reefs. As In-fa progresses, swell will become north, then northwest, resulting in surf building over west facing reefs Friday night. Surf will remain hazardous through at least Saturday afternoon. These surf conditions will maintain a high risk of dangerous rip currents.
