SAN JUAN — All Coastal Flood Advisories have been canceled, the National Weather Service said on Sunday.
Small Craft Advisories were also canceled, but deteriorating marine conditions will again trigger Small Craft Advisory criteria by tonight onwards, according to the NWS.
Overview: A dissipating northerly swell will continue to stream across the regional waters, maintaining
choppy marine conditions through Monday. Additional swell pulses will again promote hazardous
marine conditions for small craft by Monday night and Friday morning, respectively.
Despite these variations, life-threatening coastal conditions will persist throughout the workweek, mainly for beaches with northern and eastern exposure.
