These near real-time maps of the Potential Flood Index indicate the
Average Recurrence Interval (ARI) of precipitation that has occurred during the past 6 & 24 hours. Until now, it has been difficult to ascertain the precise scale of precipitation events seen in an historic context in an interactive map. The maps maps are re updated every 6-hours (00 UTC, 06 UTC, 12 UTC & 18 UTC), which coincides with
updates of the gauge-adjusted radar-estimated precipitation from the National Weather Service (NWS) .
These maps are neither official nor certified and only represent ARIs up to 100-years. Contact us
for information on our suite of low-latency (real-time), high-resolution Potential Flood Index analysis and forecast maps with ARIs up to 1000+ years.
