24 expect major flooding. Historically, numerous homes and the Willapa Hatchery at Fork Creek have been completely flooded at this point, along with major flooding of numerous roads from Frances downstream to Raymond, including State Route 6 and US Hwy 101.
22 expect widespread flooding. Numerous roads are flooded with deep and swiftly moving water, including Heckard Road and US Hwy 101. The magnitude of flooding on Hwy 101 will depend on the tide.
21 expect flooding of several roads along the river, including Heckard Road. Portions of US Hwy 101 may be flooded as well if flood crest corresponds to high tide. Also expect minor flooding in Raymond.
19 the river is at bankfull level. Above this level, it begins to spill over the banks into adjacent low lands. Some minor flooding is possible in Raymond if this river level accompanies high tide.
18 high river flows combined with anomalously-high tides may cause some lowland flooding in and near Raymond, including low areas on Hwy 101 in Raymond and Heckard Road near Willapa.
