What should I know about inland flooding caused by hurricanes/tropical cyclones?

Heavy rainfall is associated with slower moving storms as slower moving hurricanes/tropical cyclones allow heavy rain to persist over a particular area. Over the last 30 years, inland freshwater floods have accounted for 59% of hurricane-related deaths in the United States. There is a danger of flash floods in creeks, streams, or in urban areas (insufficient storm drain systems, etc.). Streets can become rivers with strong currents and underpasses can become deathtraps. River flooding associated with these storms can last over a week in extreme cases.
