The findings revealed that rain, which led to flooding and landslides, was the most deadly part of the storm, followed by wind, which toppled trees. And they showed that most of the deaths happened in counties where the risk of hurricane fatalities had been considered low, according to data from the Federal Emergency Management Agency.
