Warning: This system contains automated rain gages from Ventura County and surrounding counties. These gages send a radio transmission when enough rain has fallen to "tip" the bucket. The amounts varies from 0.01" to 0.04" (1mm). The flood warning network also receives data via GOES Satellite radios. Additional satellite data is received from the USGS, RAWS (Remote Automated Weather Stations) and other automated rain gages. Satellite data are transmitted on a regular basis due to bandwidth limitations on the satellite. This means that data can be delayed up to 4 hours and no reports sooner than 1 hour. Since all the data is automated, errors due to transmissions are possible. The data available on this web site is provisional and has not been checked or verified for accuracy. All data should be considered preliminary and is subject to change without notice. These maps and reports were created solely for the convenience of the County, other agencies and the public. The County does not warrant the accuracy of these maps and reports, and no decision involving a risk of economic loss or physical injury should be made from the data available on this site.
