Current Radar
The Current Radar map shows areas of current precipitation at the national or regional level. A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc.), and forecast its future position and intensity. Modern weather radars are mostly doppler radars, capable of detecting the motion of rain droplets in addition to intensity of the precipitation.

Radar Storm Tracking
Radar Storm TrackingDigital radar systems now have capabilities far beyond what their predecessors only dreamed of. Digital systems now offer storm tracking surveillance. This provides users with the ability to acquire detailed information of each storm being tracked. Storms are first identified by the radar by matching the raw data received from the radar pulse to some sort of template, preprogrammed into the system. Once the storm is identified speed, distance covered, direction, and Estimated Time of Arrival (ETA) of the storm are all tracked and recorded into a memory location of the radar in order to be utilized later. In order for a storm to be identified it would have to meet the definitions of a storm, as programmed by the manufacturer. Otherwise, any cloud could be mistaken for a storm. Usually the storm must show signs of organization. The storm must have a core or a more intense center to be identified and tracked by digital radar tracking systems.
