NEXRAD or Nexrad (Next-Generation Radar) is a network of 159 high-resolution S-band Doppler weather radars operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and the U.S. Air Force within the ...
In the United States NEXRAD network some of these angles are .5, 1.45, 2.4, and 3.35 degrees with the radar having up to 14 angles when it is in Severe Mode. [ 1 ] [ 2 ] In the composite reflectivity product, the highest intensities among those available on the different angles above each point in the image will be displayed.
Map of regions covered by the 122 Weather Forecast Offices. The National Weather Service operates 122 weather forecast offices. [1] [2] Each weather forecast office (WFO or NWSFO) has a geographic area of responsibility, also known as a county warning area, for issuing local public, marine, aviation, fire, and hydrology forecasts.
A NEXRAD weather radar currently used by the National Weather Service (NWS) is a 10 cm wavelength (2700-3000 MHz) radar capable of a complete scan every 4.5 to 10 minutes, depending on the number of angles scanned, and depending on whether or not MESO-SAILS [7] is active, which adds a supplemental low-level scan while completing a volume scan.
By and large, meteorological monitoring is done operationally by relatively legacy weather radar systems – in the United States, the NEXRAD network has been the primary weather radar network since the early 1990s. For the first 20 years of operations, its data output was, in comparison to modern schemes, considerably more modest.
This image is in the public domain because it is from one or more of the U.S. government’s 159 NEXRAD radars, which are jointly owned and operated by the National Weather Service (NWS), an agency of the National Oceanic and Atmospheric Administration (NOAA) within the United States Department of Commerce, the Federal Aviation Administration (FAA) within the Department of Transportation, and ...

In total, the tornado caused $6.6 million (2023 USD) in damage and injured three people along its 23.66 miles (38.08 km) path. [1] [2] A CoreLogic analysis estimated "approximately 18,600 single and multifamily residential properties with a combined reconstruction value (RCV) of $4.6 [billion] were potentially within the tornado path in Harris County", though the number of damaged or destroyed ...
