* WHAT...Flooding caused by excessive rainfall continues to be possible. * WHERE...A portion of northwest California, including the following areas, Mendocino Coast, Northeastern Mendocino Interior, Northern Humboldt Coast, Northern Humboldt Interior, Northern Lake, Northwestern Mendocino Interior, Southeastern Mendocino Interior, Southern Humboldt Interior, Southern Lake, Southern Trinity, Southwestern Humboldt and Southwestern Mendocino Interior. * WHEN...From Friday afternoon through Sunday 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. Storm drains and ditches may become clogged with debris. * ADDITIONAL DETAILS... - Widespread moderate to heavy rain from two consecutive strong weather systems will produce 2-4 inches of rainfall Friday afternoon through late Sunday. - http://www.weather.gov/safety/flood

* WHAT...For the Coastal Flood Warning, High astronomical tides and large surf will cause moderate to major flooding in low lying areas along the Redwood, around Humboldt Coast, and Mendocino Coast. Up to one half foot of saltwater inundation above ground level is possible in low lying areas near shorelines and tidal waterways. Between 9.1 and 9.4 feet MLLW at the Crescent City tide gauge is predicted. Between 9.8 and 10.1 feet MLLW at the north spit tide gauge is predicted. Between 8.3 to 8.6 feet MLLW at the Pt Arena tide gauge is predicted. For the Coastal Flood Watch, High astronomical tides and large surf may cause moderate/major flooding in low lying areas along the Redwood, around Humboldt Coast, and Mendocino Coast. Up to one half foot of saltwater inundation above ground level is possible in low lying areas near shorelines and tidal waterways. * WHERE...Coastal Del Norte, Northern Humboldt Coast, Southwestern Humboldt and Mendocino Coast Counties. * WHEN...For the Coastal Flood Warning, from 7 AM to noon PST Friday. For the Coastal Flood Watch, from Saturday morning through Sunday afternoon. High tide is at 8:54 am at PT Arena tide gauge, at 9:41 am at the Crescent City tide gauge, and at 9:53 am at the Humboldt Bay North Spit tide gauge. Saltwater inundation will be possible 1 to 2 hours before and after high tide. * IMPACTS...Several coastal roads may be closed. Low lying property and some critical infrastructure will be inundated. These impacts will include, but not limited to, roadways in King Salmon and the Arcata bottoms, and sections of highway 1 and 101. Shoreline erosion will occur.
