Flood Watch remains, heavy rains moving East of the Olympics
Significant rainfall is expected especially east of the Olympics. Up to 2 inches of rain could fall today, with higher amounts in the central cascades.
Excessive rainfall could lead to urban and small stream flooding. National Weather Service Hydrologist Brent Bower tells us “Because the rainfall amounts could come in very short periods of time. So you might see street flooding, around homes, low lying areas, that type of thing.” Intense rainfall with thunderstorms could result in flash flooding and overwhelm storm drains, leading to flooded roads. mud or rock slides are also possible in steep mountainous terrain.
Significant rises can be expected on area rivers but flooding is unlikely.
Stay out of the ditches in Olympia, the national weather service also has an Urban and small stream flood advisory in effect for minor flooding of poor drainage areas in Eastern Thurston, Lewis, and Pierce counties until 8:45 this morning.
