Texas is unusually clear about how the window should be measured, and it matches how this product was built: a rolling 24 hours, not accumulation reset at midnight.

Defaults we ship, not legal advice. Your individual permit governs, and every threshold is editable per site.
What it means on site
Rain that starts at 22:00 and runs to 02:00 is a single event and is measured as one. Tools that accumulate against the calendar day split it in half and neither half reaches the threshold — so nobody is told to inspect a storm that plainly qualified.
Most of Texas is Central; El Paso and part of Hudspeth County are Mountain. Deadlines are computed in each site's own timezone, which is stored per site and never defaulted.
TXR150000 requires a routine inspection every 14 calendar days regardless of rain. It sits on the same dashboard as the storm-triggered work, ranked by what is due soonest.
Same everywhere
Whatever your state's number is, the reading it is compared against matters just as much. We run NOAA Stage IV and NOAA MRMS independently, store both per site, alert on the higher, and flag it when they disagree. Neither is averaged into the other.
Texas questions
0.5 inches or more in a 24-hour period under TXR150000, with the inspection due within 24 hours. A routine inspection is separately required every 14 calendar days.
Yes — Houston, Dallas-Fort Worth, San Antonio, Austin, El Paso and everywhere between. Coverage comes from one national NOAA radar grid, so fleet size does not change what is monitored.
The reading is reported as unavailable, never as 0.00 inches. A site the radar cannot see must never look identical to a dry one.
Not a compliance guarantee. This is a monitoring and recordkeeping aid. Where your permit names an on-site rain gauge as the system of record, the gauge is the record — and the inspector's judgement outranks ours.
