WaterWatch PRO displays a site-specific 3-day forecast for your locations on the app from the National Weather Service. When the 24-hour forecast is expected to exceed your notification threshold, you'll receive a notification along with a link to see the most recent 72-hour precipitation history at that location.
WaterWatch PRO normally displays the most recent 48 hours of data for monitored locations. This upgrade feature lets users select a date/time range and view a the results on the app or receive a report via email.
The RapidRain feature uses raw NOAA radar data to track rainfall every fifteen minutes. This is ideal for those needing to take quick action when rain falls. Plus, you and the contacts you define can receive a notification when thresholds you define are met.
Need to know the 25-year rain event? The 100-year event? WaterWatch PRO knows these values for your location and proactively compares detected rainfall against these historic maximums. The app will also notify you when those values are reached, keeping you ahead of a flood.
WaterWatch PRO uses NOAA data to monitor rainfall and sends you a notification via text and/or email when sufficient rain meets a threshold you define within a 24-hour period. This provides you with hyper-focused, accurate and timely rainfall data for any location in the U.S. - right on your mobile phone.
WaterWatch PRO provides updated daily precipitation forecasts for the Continental U.S. from the National Weather Service. This gives you a general idea of when rain might occur for the next three days.
Each month, receive an emailed report of the hourly, daily, and monthly rainfall for your monitored locations. Also, WaterWatch PRO sends you a daily text and email notification of the prior day's rainfall at each monitored location. Automate your record-keeping and lower your operating costs.

The National Oceanographic and Atmospheric Administration (NOAA), which is the parent government organization of the National Weather Service (NWS), processes digital representations of rainfall. One of the tools used by NOAA compiles and analyzes Doppler radar-derived precipitation measurements, generating hourly grids with data points spaced at 1-km (1/2-mile) intervals across the continental United States – a so-called “rainfall map.”
This highly detailed picture of hourly data is based on a combination of various sources:
· Precipitation data from a network of 180 NWS-maintained overlapping dual-polarization Doppler radar networks.
· Analysis of nearly 20,000 rain gauges.
· Satellite data processed at 15-minute intervals.
· Observations from hourly automatic reporting instruments (often located at airports).
· Numerical models and climatology.
Among other uses, this digital rainfall map is input to NWS flood guidance, producing flash flood forecasts essential to public safety. In operation since 2014, this integrated weather data stream was awarded a NOAA Silver Medal in 2015, one of the highest recognitions conferred by NOAA.
The key to this approach is the process of incorporating rain gauges into the hourly data stream alongside Doppler radar-derived rainfall measurements. Doppler radar computes precipitation based on the empirical relationship between radar reflectivity measured from the beam and the rainfall rate.
However, the beam is located above the ground, meaning it does not fully capture the amount of rain reaching the ground. Therefore, incorporating available rain gauges enhances the accuracy of the rainfall determined from the radar data.
WaterWatch PRO collects and processes this hourly digital rainfall map. It then utilizes a proprietary method to identify a client’s GPS location within the nearest 1-km grid section.
During processing, no further data interpolation is made of the client’s GPS location within the 1-km grid field.
Our proprietary method delivers more precision to critical stormwater monitoring rainfall measurements. By using a computerized, automated system, WaterWatch PRO accounts for variances in time and space.
This process makes WaterWatch PRO an ideal way to account for highly localized rainfall events, producing a reliable NOAA data source you can confidently trust.
