Beach Hazards Statement 10 PM Tue to 10 PM Thu

More rain on the way, but how much? Let's take a look as most reasonable outcomes. There is some uncertainty regarding exact placement of rainfall maximum. Utilization probabilistic information gives meteorologists a "boom vs bust" scenario and most likely amounts.

Expect long period south swell with breaking waves up to 10 to 14 feet from 10 PM Tuesday to 10 PM Thursday along the coast from Monterey County to Sonoma County. Impacts include dangerous swimming and surfing conditions. 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.
