Feedback from Emergency Managers • “It's like having you and your team of experts standing right with us. Your credibility is never questioned when we can show the hazards approaching using a BlackBerry or other PDA.” • “We used the graphical warning when making the decision to sound the sirens during the February 10 storm. We also captured screen shots of the graphical warning page to include in our "event" file for the day.” • “When questioned by elected officials as to why the sirens were sounded when the damages were in the city immediately adjacent to us, the picture and data really told the story.” • “The best thing about it for me is putting as much simplified info on the page with the map as possible and I think you have that down pretty well.”
