Understanding Radar Coverage Gaps During Winter Storms

During winter storms, accurate and timely weather information is crucial for safety and preparedness. However, certain areas in the United States experience radar coverage gaps that can hinder the detection and monitoring of these storms.

What Are Radar Coverage Gaps?

Radar coverage gaps occur when radar beams fail to detect precipitation or storm activity due to various factors, including distance from the radar, terrain obstructions, and the curvature of the Earth. These gaps are particularly significant at lower altitudes, where winter storms primarily develop. For instance, the Next Generation Weather Radar (NEXRAD) system, a network of 159 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, has coverage limitations below 10,000 feet in many parts of the United States.

Where Are These Gaps Located?

Radar coverage gaps are more prevalent in certain regions due to factors such as distance from radar sites and mountainous terrain. Areas like Alaska, parts of Oregon, the Rocky Mountains, and the Four Corners region often experience these gaps. Notably, many of these gaps lie in Tornado Alley, where undetected tornadoes have occurred due to such coverage limitations. (en.wikipedia.org)

How Do Radar Gaps Affect Winter Storm Monitoring?

During winter storms, radar coverage gaps can lead to delays in detecting and tracking storm development, intensity, and movement. This can result in less timely warnings and reduced preparedness for affected areas. For example, in mountainous regions, the NEXRAD beam may overshoot low-level precipitation, leading to underestimation of storm severity. (climeradar.com)
