Rainfall, Precipitation, Weather, Map, Los Angeles County

NOTE: When most weather reporting sources cite weather in Los Angeles (without specifying where, exactly, in Los Angeles), these numbers are typically for the Downtown Los Angeles weather station (actually located on the USC campus).

Established in 1949, the Pierce College Weather Station in Woodland Hills is reported to have been one of the first official cooperative weather stations in the United States to independently provide its archived data online and one of the oldest unmoved operational cooperative weather stations in the world. In late March 2020, as California began closing down to deal with the COVID-19 pandemic, Pierce College Weather Station discontinued their online presence, thereby making direct daily weather reports unavailable.
