A Wind Advisory is in effect for Del Norte and Humboldt counties from Monday evening into early Tuesday. A strong storm system will approach the coast on Monday evening, bringing another round of strong south winds. The strongest winds are anticipated for the coastal headlands and exposed ridges.
A Flood Watch is in effect from Monday evening through Tuesday evening for Del Norte, Humboldt, Trinity, Mendocino and Lake counties. Flooding caused by excessive rainfall is possible. There will be an increased risk of rock and land slides along roadways. Excessive runoff may result in minor flooding for small streams and creeks, and other low-lying and poor drainage areas.
Periods of moderate to heavy rain are likely starting this evening and continuing through Tuesday. Del Norte, Humboldt, Trinity, and northern Mendocino counties will see the most precipitation with 2-4 inches forecast. Southern Mendocino, Coastal Humboldt, and Lake Counties are forecast to see 1-3 inches of total rainfall.
A Coastal Flood Advisory has been issued for areas around Humboldt Bay from 3 AM to 5 AM Tuesday 2/24. Strong southerly winds offshore are expected to increase storm surge. Along with high astronomical tides, this may cause minor coastal flooding impacts around Humboldt Bay, including the Arcata Bottoms and around King Salmon.
