There is a 10–20% chance of isolated interior thunderstorms this afternoon and evening. This includes interior Del Norte, interior Humboldt, northeastern Mendocino, and Trinity counties. The highest chance is over northeastern Trinity County. Brief heavy downpours, lightning strikes, and gusty, erratic winds are possible with the strongest storms. Pay attention to storm threats and remember, when Thunder Roars, Go Indoors!
A very long period swell will begin building along the coast on Wednesday and peak around 7 feet on Thursday. The swell, combined with mostly calm winds Thursday, will generate a moderate risk of sneaker waves, especially on northwest facing beaches. Never turn your back on the ocean!
