Episode Narrative A stationary trough of low pressure off the Pacific Northwest Coast steered a deep fetch of subtropical moisture over the Cascade Mountains from March 29th through the 31st. This resulted in several rounds of moderate to heavy rainfall mainly near the immediate crest. Mild temperatures and breezy winds accompanying the subtropical moisture feed resulted in excessive mid-elevation snowmelt. Consequently, saturated soils became unstable in some locations resulting in small debris flows.
Event Narrative A trained spotter reported minor flooding of First Creek which resulted in some damage along First Creek Road.
