Flash Floods and Hail property and personal devastation
Cases involving either slow-moving thunderstorms or a series of storms which move repeatedly across the same area (sometimes called train-echo storms) frequently result in flash flooding.
Floods are a fact of life in a Queensland summer. Some towns are particularly prone, as was Clermont in the 19th and early 20th centuries.

Flood- a condition that occurs when water overflows the natural or artificial confines of a stream or river; the water also may accumulate by drainage over low-lying areas.
flood: when water overflows the confines of a body of water and gathers over low-lying areas.

Flood Warning
The expected severity of flooding (minor, moderate or major) as well as where and when the flooding will begin.
Foehn
Wind warmed and dried by descent, in general on the lee side of a mountain.

Flash Flood: A flood caused by heavy or excessive rainfall in a short period of time, generally less than 6 hours. A flash flood rises rapidly, often with little or no warning.
Flash Flooding - Rapidly-developing flooding of tributaries, usually as a result of thunderstorms.
Flash flood A sudden rise in river or stream levels causing flooding.
Forced convection Convection aided by topographic uplift or converging surface winds.
Free convection Convection triggered by intense solar heating of Earth's surface.
Annual Flood
In hydrologic terms, the maximum discharge peak during a given water year (October 1 - September 30).

Flood tide
The portion of the tide cycle between low water and the following high water. It is sometimes called "rising tide".
Fog ...
Flood - It results from days of heavy rain and/or melting snows, when rivers rise and go over their banks.
Flood Plain - The lowland that borders a river, usually dry but subject to flooding when the river is high.
Flooding caused by a rapid rise in the water level of rivers, streams, or lakes, usually as a result of heavy rains.
Fog

Flow: 1. wind; 2. volume of air carried by wind.
FLASH FLOOD - A sudden flood of water caused by heavy rainfall in a short period of time or sudden snowmelt. Flash floods could occur as ponding of water in low areas or a destructive wall of water.
Hurricane: flooding, devastation.
