Description:
The graphic depicts the potential impact from tropical cyclone floods across the specified area valid through the event. It is based on the likelihood of rainfall amounts exceeding flood guidance for the local area.
Important Note: Worded expressions describe the expected impact relative to the latest forecast conditions, while Graphic expressions convey the potential impact relative to the uncertainty of forecast conditions.

TEST.
None
Threat -
No discernible threat to life and property; the likelihood for higher rain
totals to remain below flash flood guidance.
Potential Impact - None expected heavy rain may still
occur.
Very Low
Threat -
A limited threat to life and property; the likelihood for higher rain totals
to approach flash flood guidance.
Minimum Action - Prepare for the likelihood of damage
consistent with very minor inland flooding.
Potential Impact - A very low impact to communities
within the specified area. Isolated locations may experience minor inland
flooding.
Low
Threat -
An elevated threat to life and property; the likelihood for higher rain
totals to be around flash flood guidance.
Minimum Action - Prepare for the likelihood of damage
consistent with minor inland flooding.
Potential Impact - A low impact to communities within
the specified area. Isolated to scattered locations may experience minor
inland flooding.
Moderate
Threat -
A significant threat to life and property; the likelihood for higher rain
totals to exceed flash flood guidance.
Minimum Action - Prepare for the likelihood of damage
consistent with moderate inland flooding.
Potential Impact - A moderate impact to communities
within the specified area. Isolated locations may experience moderate
inland flooding, among scattered locations of minor flooding.
High
Threat -
A critical threat to life and property; the likelihood for higher rain
totals to well exceed flash flood guidance.
Minimum Action - Prepare for the likelihood of damage
consistent with major inland flooding.
Potential Impact - A high impact to communities within
the specified area. Isolated locations may experience major inland flooding,
among scattered locations of minor to moderate inland flooding.
Extreme
Threat -
An extreme threat to life and property; the likelihood for higher rain
totals to greatly exceed flash flood guidance.
Minimum Action - Prepare for the likelihood of damage
consistent with very major inland flooding.
Potential Impact - An extreme impact to communities
within the specified area. Scattered locations may experience major inland
flooding, among many locations of minor to moderate inland flooding.
Minor Flooding — Within 6 hours
after heavy rain, small streams, creeks, canals, and drainage ditches
become swollen and overflow in a few places. In flatter terrain, quick
ponding of water occurs around low-lying spots, especially in historically
vulnerable locations. In urban places, quick ponding of water occurs
at certain underpasses or poor drainage spots, especially in historically
vulnerable locations. Storm drains and retention ponds become near-full
and begin to overflow in a few places. In mountain areas, runoff moves
down the valley and is becoming a concern, especially in river valleys.
Flood waters generally affect a few buildings and roads.
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.
Small streams, creeks, canals, and drainage ditches overflow. Normally
dry gullies or dry creek beds become alive. In flatter terrain, expanded
areas of rapid inundation occur around low-lying spots covering several
secondary roads. 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. Storm drains and retention ponds
overflow. In mountain areas, considerable runoff moves fast down the
valley washing out some roads, especially in river valleys. Hillsides
vulnerable to erosion become a concern for mudslides. Flood waters generally
affect several buildings and roads.
Major Flooding — Within 6 hours after heavy rain,
rivers and tributaries overflow their banks in several places. Small
streams, creeks, canals, and drainage ditches become dangerous rivers.
Normally dry gullies or dry creek beds become alive with dangerous and
fast moving water. In flatter terrain, extensive inundation occurs covering
both primary and secondary roads. In urban places, widespread inundation
with streets and parking lots becoming rivers of moving water. In mountain
areas, destructive runoff moves fast down the valley washing out everything
in its path, especially in river valleys. Hillsides vulnerable to erosion
give way to mudslides. Flood waters generally affect many buildings and
roads.
