ESFEKA A series of atmospheric rivers will bring an increased risk for urban and small stream flooding late this week and into this weekend. The first round of rain will arrive Wednesday night into Thursday and provide generally light to moderate rainfall amounts. Locally heavy rain is expected in the King Range. This initial period of rain will set the stage for a more intense rainstorm expected to arrive Friday into Friday night. Current indications are for the heaviest rainfall to occur during the day on Friday into Friday night. The greatest risk for small stream flooding will occur during this time period and probably continue into Saturday after heavy rain has ended due to the lag in rainfall run-off. Road closures will be possible. At this point, the area of greatest concern is in southern Humboldt and northwest Mendocino counties. Small rivers, streams and creeks such as Elk river, Jacoby creek and Mattole river could exceed their banks and flood area roads. Southern Mendocino and Lake counties may also experience heavy rain and road flooding will be possible. Mainstem rivers will also likely rise sharply and will need to be monitored for possible flood stage exceedance. Be on the lookout for watches, advisories and warning as this next heavy rain event unfolds. Plan to avoid driving through areas that tend to flood.

* WHAT...Flooding caused by excessive rainfall is 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. Additional heavy rainfall will be possible Sunday through early next week. * 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
