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
Automated airport weather station than actual. Current sensors are capable of reporting visibility in a wide range. For aviation purposes, the reported values are rounded down to the nearest step in one of the following scales: Automated airport weather stations use a Light Emitting Diode Weather Identifier (LEDWI) to determine if and what type of precipitation is falling. The LEDWI sensor measures the scintillation pattern of the precipitation falling through the sensor's infrared beam (approximately 50 millimeters in diameter) and determines from a pattern analysis of the particle size and fall velocity whether the precipitation is rain or snow. If precipitation is determined to
