PrecipWatch Watches the Second Storm
A stormwater compliance tool that watches rainfall at permitted sites and alerts inspectors when a permit threshold is crossed.
Field notes
The product evaluates a rolling 24-hour rainfall total against the threshold attached to each permitted site, checking every five minutes. Its displayed Georgia example shows NOAA Stage IV and MRMS readings separately, including a case where they disagree by 0.15 inches and the alert uses the higher value. The page also describes a six-hour dry-period reset, local-time deadline calculation, forecast warnings, and signed PDF records for later inspection or audit workflows.
