WES Case for Winter 2006: The 25 February 2004 San Francisco Urban Flash Flood Event

摘要

Cool-season flooding is, on average, the most significant of the various short-fused weather related hazards that occur in our CWA. As these also have some rather unique aspects in the sort of heavily urbanized environments that prevail within our CWA, we decided review of a relatively recent and significant urban flood occurrence would provide for a valuable WES training exercise. The case chosen was the 25 February 2004 San Francisco and San Mateo county flash flood event, which was driven by torrential short-term rainfalls associated with convective elements embedded in a land-falling Pacific cold front.
