PreVieux is our 1-hour nowcast that updates and animates every 5 minutes for each 5 minute increment. One to two hour predictive rainfall forecasts are made possible by projecting current radar into the future for 60-minutes beyond currently detected precipitation. Our predictive rainfall service relies on a patented and licensed algorithm to project the storm path, intensification or decay, and aggregate the results in terms of sewershed accumulation or rainfall intensity.
The forecast rainfall information is shown as images, and can be integrated with other systems in interoperable formats such as XML. Pager notification and cell phone or handheld display options are available to notify clients of likely rainfall in high impact areas. Thresholds can be set for notification once the threshold is crossed for any basin on a detected or predictive basis.
