* WHAT...Flooding caused by excessive rainfall is possible. * WHERE...Del Norte County, Humboldt County, Trinity County, Mendocino County, and Lake County. * WHEN...From this evening through Friday evening. * IMPACTS...There will be an increased risk of rock and land slides along roadways. Excessive runoff may result in flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Creeks and streams may rise out of their banks. Flooding may occur in poor drainage and urban areas. Area creeks and streams are running high and could flood with more heavy rain. * ADDITIONAL DETAILS... - Additional rounds of heavy rain are likely again starting tonight and continuing through Friday night. An additional 4-8 inches of total precipitation is possible through Friday. There will be breaks in the heavy precipitation, but heavy rain falling on already saturated ground will promote flooding impacts. Additional precipitation amounts of 4-8 inches are possible through Friday. - http://www.weather.gov/safety/flood

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
