With the National Oceanic and Atmospheric Administration predicting that slow-moving Hurricane Sally may produce up to 30 inches of rain in Gulf Coastal states, yet another domino may fall when it comes to the list of all-time tropical-cyclone-related rainfall records broken in the United States. (Tropical cyclone is a catchall term that describes tropical depressions, storms and hurricanes.) Five states set tropical-storm-related rainfall records between 2017 and 2019 alone. There are also studies that show hurricanes are tending to move more slowly at landfall in parts of the world, including the United States, in another global-warming-linked trend. Such storms can continue to draw in moisture from warm ocean waters and dump it on land.
