INSTRUCTIONS

A Coastal Flood Advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore.

Feet Above Ground is locally defined as feet above the Highest Astronomical Tide or HAT.

DESCRIPTION

* WHAT…High astronomical tides will cause minor flooding in low lying areas around Humboldt Bay. Up to half foot of saltwater inundation above ground level is possible near shorelines and tidal waterways. Between 8.9 and 9.1 feet MLLW at the North Spit tide gauge is predicted.

* WHERE…Northern Humboldt Coast County.

* WHEN…From 9 AM to 1 PM PST Sunday. High tide is at 10:42 AM PST at the Humboldt Bay North Spit tide gauge. Saltwater inundation will be possible 1 to 2 hours before and after high tide.

* IMPACTS…Flooding of low lying areas around Humboldt Bay including parks and roads with only isolated closures expected. Flooding will likely impact Jackson Ranch Road in the Arcata Bottoms and several roads in King Salmon.
