Public Works operates and maintains a network of rain gages to collect rainfall (precipitation) data for the purposes of in-house engineering and design of flood control and water conservation facilities.
RAINFALL AMOUNTS:
Although Public Works operates and maintains 242 rain gages, including those which record amounts for durations ranging from 5 minutes to 24 hours, only daily and annual amounts for the report period are listed herein. Additional data (e.g., intensities) can be obtained by contacting the custodian of hydrologic records.
ALERT SYSTEM Automated Local Evaluation in Real Time:
Public Works operates and maintains a state-of-the-art ALERT computer system to monitor meteorological conditions in the County and Southern California in real time, i.e., as they occur. The system includes a network of field sensors that monitor and receive precipitation amounts including rainfall data from the Corps of Engineers' Los Angeles Telemetry System.
COOPERATION:
The cooperation of observers in furnishing rainfall data to Public Works as a public service is appreciated. The effort of the many agencies and individuals who have so freely cooperated with us in the collection of this data have resulted in the large number of complete records for the period covered by this report.
Data from 22 stations of Public Works' records are reported and published by the National Oceanic and Atmospheric Administration (NOAA).
