Term Definition
Feeder Bands

In tropical parlance, the lines or bands of thunderstorms that spiral into and around the center of a tropical system. Also known as outer convective bands, a typical hurricane may have three or more of these bands. They occur in advance of the main rain shield and are usually 40 to 80 miles apart. In thunderstorm development, they are the lines or bands of low-level clouds that move or feed into the updraft region of a thunderstorm.

Flood Plain

Any land area susceptible to being inundated by water from any source. Normally the regulatory flood plain is characterized by the 100-year meaning there is a 1% chance of flooding per year. The flood plain is often referred to as flood prone areas.

Flood Warning

The expected severity of flooding (minor, moderate or major) as well as where and when the flooding will begin.


A general and temporary condition of partial or complete inundation of normally dry land areas from the overflow of inland or tidal water or rapid accumulation or runoff of surface waters from any source.


A statement of expected future occurrences. Weather forecasting includes the use of objective models based on certain atmospheric parameters, along with the skill and experience of a meteorologist. Also called a prediction.

Forward Speed

The rate of movement (propagation) of the hurricane eye in miles per hour or knots

Fujiwhara Effect

A binary interaction where tropical cyclones within a certain distance (300-750 nautical miles depending on the sizes of the cyclones) of each other begin to rotate about a common midpoint.
