aerial flood warning definition
An Areal Flood Warning is issued for flooding that occurs more gradually, normally from prolonged and persistent moderate to heavy rainfall. Areal is an adjective referencing a particular area or region. Example of areal flooding via kwout. In hydrologic terms, (1) A part of the flood plain, otherwise leveed, reserved for emergency diversion of water during floods. A part of the flood plain which, to facilitate the passage of floodwater, is kept clear of encumbrances. An established gage height for a given location above which a rise in water surface level begins to create a hazard to lives, property, or commerce. The issuance of flood (or in some cases flash flood) warnings is linked to flood stage. Terms defined for each forecast point which describe or categorize the severity of flood impacts in the corres­ponding river/stream reach. Each flood category is bounded by an upper and lower stage (see Example 1). An Areal Flood Warning is issued for flooding that occurs more gradually, normally from prolonged and persistent moderate to heavy rainfall. Areal is an adjective referencing a particular area or region. This results in a gradual ponding or buildup of water in low-lying, flood prone areas, as well as small creeks and streams. Basically an Areal Flood Watch means there is potential for flooding over a large area. The word “areal” is the adjective version of the noun “area.”. There’s no word on why the National Weather Service changed the name of the watch. The word “areal” refers to an area, which is an expanse of space or a region of land. Not to be confused with “aerial” which means of or relating to the air. If a view existed from the air of a large expanse of land, it would be an aerial areal view; in other words a view of the area from the air. Anyway, you may have noticed use of the word “areal” in the yellow or red bar at the top of cbsnewyork.com during the recent rash of rain. The National Weather Service adopted the new term several years ago which generally means the same as the more commonly used “Flood Watch” designation. ‘Areal,’ although it looks like it’s misspelled, is correct in reference to an areal flood warning. Like most meteorological terms, the word has a Latin origin. (Areal is the adjective form of area and is not the same as ‘aerial’). Technically, we could show an aerial image of an areal flood. The National Weather Service issues many hydrology related products. Some are to warn you of potential hazards; others are information statements to keep you up to date on changing weather and river situations. An areal flood warning means that the flooding happens over a longer period of time (like several days) from extended periods of rain. It also covers more area or space. So instead of just a river, it would cover multiple counties.
