Though New Orleans residents were told to evacuate days before the arrival of Hurricane Katrina, no one could have predicted the real extent of the devastation.Now researchers from Tel Aviv University say they have found a novel and reliable way to help predict the intensity of the next big flood, using common cell phone towers across the United States. Their model, which analyzes cell phone signals, adds a critical component to weather forecasting never before available."By monitoring the...
