Storm surge is an abnormal rise of water generated by a storm, over and above the predicted astronomical tides. Storm surge should not be confused with storm tide, which is defined as the water level rise due to the combination of storm surge and the astronomical tide. This rise in water level can cause extreme flooding in coastal areas particularly when storm surge coincides with normal high tide, resulting in storm tides reaching up to 20 feet or more in some cases.

This web application was created to show dynamically, how the storm tide can effect where you live and other places of interest. You can locate where you are now (if you allow the app to get your location from your browser), or you can enter an address or place into the search bar at the top. The app will zoom in and you can also choose to toggle the background map to show all the streets. This web app or tool will only function in the Tampa Bay area.
