On subsequent trail runs flooding, debris flows and erosion were noted in Upper Sycamore and Blue Canyons in Pt. Rainfall totals in Los Angeles, Ventura and Santa Barbara Counties for the storm generally ranged from 4 to 8 inches with some higher totals recorded. The atmospheric river event on February 17 produced high flows on many local streams and many of these streams continue to flow.
One tangible indicator of this deficit is that despite above average rainfall, many creeks in the Santa Monica Mountains and Simi Hills have remained dry or are barely flowing. It’s hard to appreciate the size of this deficit while running in the rain, splashing through puddles, and trying not to slip in the mud. There has been a five year precipitation deficit of nearly 36 inches at Downtown Los Angeles (USC). Just how much a continued wet rain season would impact the drought in the long term is a question that has to wait for future analysis. The rain has been very beneficial and has impacted the drought, at least in the short term. By either measure Los Angeles rainfall is well above normal, and with three well-advertised storms in the forecast it looks like Los Angeles rainfall could remain above normal for at least a few weeks.Įven if it has been a bit wet - and muddy - it’s been great to have a more normal rain season. As of yesterday Downtown Los Angeles (USC) has recorded 8.80 inches of rainfall for both the Rainfall Year (July 1 – June 30) and Water Year (October 1 – September 30).
