Loading live data… · Marker positions are approximate; severity is labelled in each popup. Sources: USGS, GDACS, NASA EONET, NOAA/NWS, EMSC.
* WHAT...For the High Surf Warning, dangerously large breaking
waves of 12 to 18 feet expected. For the High Surf Advisory,
large breaking waves of 8 to 12 feet expected in the surf zone.
For the Coastal Flood Statement, isolated minor coastal flooding
up to 1 foot expected. For the High Rip Current Risk, dangerous
rip currents expected.
* WHERE...North and east facing reefs of Tinian and Saipan.
* WHEN...For the High Surf Warning and Coastal Flood Statement,
from 1 AM to 4 PM ChST Friday. For the High Surf Advisory, from
4 PM Friday to 4 PM ChST Saturday. For the High Rip Current Risk,
from late tonight through Saturday afternoon.
* 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.
