The primary concern for the public is the life-threatening danger posed by sneaker waves. These are unexpectedly large waves that surge much farther up the beach than preceding waves, catching unsuspecting individuals off guard. The immense power of the surf is also expected to dislodge heavy driftwood and other debris, turning them into dangerous projectiles. The National Weather Service is strongly advising against any beachcombing or activities near the shoreline. Coastal communities, infrastructure, and local ecosystems are also at risk from increased erosion and potential flooding. The heavy snow in the mountains could impact travel and pose avalanche risks.
