Storm drains and retention ponds become near-full and begin to overflow in a few places. In urban places, quick ponding of water occurs at certain underpasses or poor drainage spots, especially in historically vulnerable locations. In flatter terrain, quick ponding of water occurs around low-lying spots, especially in historically vulnerable locations. Minor Flooding: Within 6 hours after heavy rain, small streams, creeks, canals, and drainage ditches become swollen and overflow in a few places. * Isolated to scattered locations may experience minor flooding. Potential Impacts: There is an elevated threat to life and property. * Isolated locations may experience moderate flooding, among scattered locations of minor flooding. There is a potential for higher rainfall amounts which could overwhelm local drainage capacity. Potential Impacts: There is a significant threat to life and property. Flood waters generally affect several buildings and roads. Storm drains and retention ponds overflow. ![]() In urban places, expanded areas of rapid inundation occur at several underpasses or poor drainage spots, with some streets and parking lots taking on moving water. In flatter terrain, expanded areas of rapid inundation occur around low-lying spots covering several secondary roads. Small streams, creeks, canals, and drainage ditches overflow. Moderate Flooding: Within 6 hours after heavy rain, rivers and tributaries become swollen and may begin to overspill their banks in a few places, especially in historically vulnerable locations. Local drainage capacities in many communities will be overwhelmed. ![]() * Most locations will experience minor to moderate flooding. * Isolated locations may experience major flooding. There is a elevated potential for higher rainfall amounts which will overwhelm local drainage capacity. Potential Impacts: There is a critical threat to life and property. Note: In all tropical cyclone situations, listen for possible flash flood watches move to higher ground if a flash flood warning is issued for your area. Flood waters generally affect many buildings and roads In urban places, widespread inundation with streets and parking lots becoming rivers of moving water. In flatter terrain, extensive inundation occurs covering both primary and secondary roads. Small streams, creeks, canals, and drainage ditches become dangerous rivers. Major Flooding: Within 6 hours after heavy rain, rivers and tributaries overflow their banks in several places. Local drainage capacity in many communities may be overwhelmed. * Scattered locations may experience major flooding, Many locations will experience minor to moderate flooding. There is a very elevated potential for higher rainfall amounts which will overwhelm local drainage capacity. Potential Impacts: There is an extreme threat to life and property. ![]()
