WeatherWatch PRO uses a proprietary method that delivers more precision to critical stormwater monitoring rainfall measurements. Our computerized, automated system accounts for
variances in time and space.
Every two minutes, a cadre of satellites, surface and upper-air observations, radar data, lightning reports, numerical weather prediction models and rain gauges, are fed through a series of proprietary algorithms to ultimately create a
highly detailed picture of hourly rainfall.
This raw data, maintained and supplied by the National Weather Service, is enhanced by trained meteorologists who analyze the results and make necessary adjustments, discarding questionable data points. The resultant rainfall grid WaterWatch PRO uses is composed of data points spaced 1/2 mile apart.
The National Weather Service uses rain gauges to calibrate this analysis field on a regular basis to account for seasonal and climatological variability. How reliable is this data? The National Weather Service uses it in predictive models that produce flood guidance for critical safety decisions.
This makes WaterWatch PRO ideal for accounting for highly localized rainfall events. You can confidently trust this reliable National Weather Service data source.
It’s happened countless times – you’re caught in a torrential downpour, but the site you’re monitoring across town didn’t get a drop. Why is that? Different natural processes occur as clouds develop, move and produce rain.
The weather systems that bring rain happen for a variety of reasons even though the result, water falling from the sky, is the same. However, that same variety of conditions
results in rainfall that isn't uniform.
Additionally, due to the dynamic nature of weather systems, rainfall can start and stop erratically. You’ve got plenty to do, and
wasting time driving needlessly to check dry sites isn’t one of them.
While it may seem that simply sticking a rain gauge in the ground guarantees results, there can be wide variances. One issue with regular rain gauges is so-called “exposure”. The amount in the gauge could be lower than it should be as falling rain is blocked by nearby obstacles. Wind also plays a factor, as gusts can blow rain into or away from the gauge.
Ultimately, you're depending on someone to go check the gauge as part of your stormwater monitoring process. In doing so, you're assuming that they don’t make a mistake or there isn't inaccuracy due to evaporation, the gauge doesn't get damaged or even stolen.
WeatherWatch PRO solves this by using an automated, accurate measuring method.
