Regional Radars

 National Nexrad network

 

Fig. 1 depicts our regional NEXRAD radars and their “theoretical” areas of coverage. In reality, our weather radar coverage is about 80-90 percent of this theoretical coverage, due to beam attenuation and extreme height of the beam at longer distances.  Additionally, mountains will block smaller scale areas, such as the Franklin Mountains blocking portions of El Paso and Hudspeth Counties. Larger areas void of data include the area north and west of Silver City and much of southern and eastern Hudspeth County.
