There is an increased risk of ocean drowning. Rip currents can pull swimmers and surfers out to sea. * ADDITIONAL DETAILS...Sunday carries the widest range of coastal flooding outcomes due to chances of rain, wind, low pressure tidal enhancements, and swells from multiple directions.

This warning may be extended past Sunday, or converted to a Coastal Flood Advisory through Tuesday.
