surf zone and increasing risk of sneaker waves and rip currents
with breaking waves up to 10 to 14 ft.
* WHERE…San Francisco, Coastal North Bay Including Point Reyes
National Seashore, San Francisco Peninsula Coast, Northern
Monterey Bay and Southern Monterey Bay and Big Sur Coast

can sweep across the beach without warning, pulling people into

changes in breathing, heart rate and blood pressure, greatly
increasing the risk of drowning in rough open waters.
