* WHAT…Large breaking waves of 20 to 30 feet.
* WHERE…Pacific Coast.
* WHEN…From 10 AM Thursday to 4 PM PST Sunday.
* IMPACTS…Dangerous swimming and surfing conditions and
localized beach erosion can be expected. Large waves can sweep
across the beach without warning, pulling people into the sea
from rocks, jetties and beaches. Sudden immersion in cold water
can result in cold water shock even for the most experienced
swimmers. Cold water shock can result in dramatic changes in
breathing, heart rate and blood pressure, greatly increasing the
risk of drowning in rough open waters.
