Caption: The study is based on data from monitoring stations along the Eastern Seaboard of the United States, where the daily tide levels have been recorded all the way back to 1923. Rapid changes in sea level show that there has been a tropical storm. The map shows cloud cover and ocean temperatures when Hurricane Katrina hit New Orleans in 2005. Warm colors show ocean temperatures exceeding 28° C which can strengthen hurricanes.
