* WHAT...High astronomical tides will cause minor flooding in low
lying areas around Humboldt Bay. Up to one half foot of
saltwater inundation above ground level is possible near
shorelines and tidal waterways. Between 9.0 and 9.3 feet MLLW
at the North Spit tide gauge is predicted.

* WHERE...Northern Coastal Humboldt County.

* WHEN...From 1 PM to 4 PM PDT Thursday. High tide is at 1:59 PM
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.

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.

* WHAT...Temperatures as low as 33 will result in frost formation.

* WHERE...Del Norte, Humboldt, and Mendocino Coast, Humboldt
Interior, Interior Del Norte, and Southwestern Interior Mendocino.

* WHEN...From 1 AM to 9 AM PDT Thursday.

* IMPACTS...Frost could harm sensitive outdoor vegetation. Sensitive
outdoor plants may be killed if left uncovered.

* ADDITIONAL DETAILS...Some valleys, especially closer to the coast,
may experience low cloud cover and/or fog, which will limit the
potential for frost.

Take steps now to protect tender plants from the cold.
