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…The perigee moon cycle is generating above normal high tides, reaching 8.03 ft MLLW Thursday and 7.94 ft MLLW Friday. Southerly winds ahead of a weather system may increase the tidal anomaly, with 0.85 to 1.0 positive tidal anomaly possible, creating a high tide of 9.0 ft at the North Spit.

* WHERE…Minor coastal flooding occurs around Humboldt Bay at tides of 8.8 ft at locations such as King Salmon, Jackson Ranch Road, and Arcata Bottoms.

* WHEN…Thursday and Friday afternoons.

* 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.
