Understanding NEXRAD Radar Coverage in 2026

The Next Generation Weather Radar (NEXRAD) system is a network of approximately 160 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), the Federal Aviation Administration (FAA), and the U.S. Air Force. These radars are essential for detecting precipitation, wind patterns, and severe weather events, providing critical data for weather forecasting and aviation safety. (ncei.noaa.gov)

What is NEXRAD?

NEXRAD, which stands for Next Generation Weather Radar, is a collaborative effort among federal agencies to monitor and predict weather conditions across the United States. The system utilizes Doppler radar technology to measure the velocity of precipitation particles, enabling the detection of severe weather phenomena such as thunderstorms, tornadoes, and hurricanes. (faa.gov)

How Does NEXRAD Coverage Work?

NEXRAD radars are strategically located to provide comprehensive coverage of the continental U.S., including Alaska, Hawaii, and Puerto Rico. Each radar has a maximum range of 230 kilometers (approximately 125 nautical miles) for Doppler velocity measurements, allowing for the detection of weather patterns at significant distances.

Limitations of NEXRAD Coverage

Despite its extensive network, NEXRAD coverage has certain limitations:

  • Terrain Obstructions: Mountains and other geographical features can block radar signals, leading to areas with reduced or no coverage. (noaa-mirror.org)

  • Line-of-Sight Constraints: The curvature of the Earth and the radar's beam height can result in blind spots, especially at longer distances from the radar site. (catalog.data.gov)

  • Offshore Gaps: While NEXRAD provides coverage along the Atlantic and Gulf coasts, offshore areas may experience reduced radar data availability. (weather.gov)
