NOAA Weather Radio typically recorded once per hour, and are broadcast at 5 or 10, and at 15 minutes past the hour. A complete detail of current weather conditions (current sky condition, temperature, dew point, humidity, wind speed/direction and barometric pressure) for the main reporting station in the station's city of license. NOAA Weather Radio All Hazards has a multi-tier concept for forecasting or alerting the public to all types of weather. Actual forecasts vary by the area that the transmitter serves. During severe weather situations, Watch Information Statements for government-designated jurisdictions served by the local NWR station are typically inserted within the
Weather radar Weather radar Weather radar, also called weather surveillance radar (WSR) and Doppler weather radar, is a type of radar used to locate precipitation, calculate its motion, and estimate its type (rain, snow, hail etc.). Modern weather radars are mostly pulse-Doppler radars, capable of detecting the motion of rain droplets in addition to the intensity of the precipitation. Both types of data can be analyzed to determine the structure of storms and their potential to cause severe weather. During World War II, radar operators discovered that weather was causing echoes on their screen, masking potential enemy targets. Techniques were developed to
