Impact Levels
Inland Flooding – Potential Impact Descriptions
Extreme
Potential for Extreme Impact: Aggressive preparations should be made for the threat of catastrophic inland flood damage from heavy rain. If realized, expect several to many inland locations to experience major fresh water flooding at or near historic levels with highest (flash) flood waters capable of causing rivers and tributaries to significantly overflow their banks in multiple places. Small streams, creeks, canals, and ditches become raging rivers. Widespread rapid inundation covers both primary and secondary roads. Streets and parking lots become rivers of fast-moving water. Storm drains and retention ponds overflow. Flood waters will affect buildings and homes and may prompt many evacuations and road closures. Rescues may be necessary. Descriptions are consistent with damage caused by heavy rain where highest totals greatly exceed amounts conducive for (flash) flooding.
High
Potential for High Impact: Aggressive preparations should be made for the threat of major inland flood damage from heavy rain. If realized, expect several inland locations to experience major fresh water flooding with highest (flash) flood waters capable of causing rivers and tributaries to overflow their banks in multiple places. Small streams, creeks, canals, and ditches become dangerous rivers. Widespread rapid inundation covers both primary and secondary roads. Streets and parking lots become rivers of moving water. Storm drains and retention ponds overflow. Flood waters may affect buildings and homes and could prompt many evacuations and road closures. Rescues may be necessary. Descriptions are consistent with damage caused by heavy rain where highest totals well exceed amounts conducive for (flash) flooding.
Moderate
Potential for Moderate Impact: Preparations should be made for the threat of moderate inland flood damage from heavy rain. If realized, expect several inland locations to experience moderate fresh water flooding with highest (flash) flood waters capable of causing rivers and tributaries to become swollen and overspill their banks in a few places, mainly in historically vulnerable places. Small streams, creeks, canals, and ditches overflow. Expanded areas of rapid inundation occur at underpasses, low-lying spots, and poor drainage areas. Some streets and parking lots take on moving water. Storm drains and retention ponds overflow. Flood waters may prompt several evacuations and road closures. Descriptions are consistent with damage caused by heavy rain where highest totals notably exceed amounts conducive for (flash) flooding.  
Low
Potential for Low but Concerning Impact: Preparations should be made for the threat of minor inland flood damage from heavy rain. If realized, expect several inland locations to experience minor fresh water flooding with highest (flash) flood waters capable of causing small streams, creeks, canals, and ditches to become swollen and overflow in a few places. Quick ponding of water occurs at underpasses, low-lying spots, and poor drainage areas. Storm drains and retention ponds become near-full and begin to overflow in a few places. Flood waters may prompt a few evacuations and brief road closures. Descriptions are consistent with damage caused by heavy rain where highest totals are near amounts conducive for (flash) flooding.    
None
Potential for Little to No Impact: Preparations are not needed as appreciable damage is unlikely. However, heavy rain and nuisance flooding may still occur.   

Note: Impact statements do not account for longer-term river flooding.
