It’s happened countless times – you’re caught in a torrential downpour, but the construction 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 rainfal 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 variance. 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.
WeatherWatch PRO uses a proprietary method that delivers more precision to these critical stormwater monitoring rainfall measurements. We use a computerized, automated system that accounts for the variances mentioned above in time and space. It all starts with continuously combining vast amounts of high resolution data from across the country.
Every two minutes, a cadre of satellites, surface and upper-air observations, lightning reports, numerical weather prediction models and yes, rain gauges, are fed through a series of propriety algorithms to ultimately create a highly detailed picture of hourly rainfall.
This raw data, supplied by the National Weather Service, is enhanced by trained meteorologists who analyze the results and make necessary adjustments, discarding questionable data points. This ensures that the stormwater monitoring performed by WeatherWatch PRO is as accurate and reliable as possible. You can trust this data because it comes from the National Weather Service.
Knowing how much rain fell at a certain point can prove to be invaluable on days where rainfall is not uniform, saving you lost hours stuck in traffic and ultimately money. This is why you can depend on WaterWatch PRO for your stormwater monitoring needs.
