Since hail can cause the rainfall estimates to be higher than what is actually occurring, steps are taken to prevent these high dBZ values from being converted to rainfall. Hail is a good reflector of energy and will return very high dBZ values. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Contact the helpdesk for operational issues. Review the Radar FAQ for help with the transition to the new site. The radar products are also available as OGC compliant services to use in your application. Depending on the type of weather occurring and the area of the U.S., forecasters use a set of rainrates which are associated to the dBZ values. The NWS Radar site displays the radar on a map along with forecast and alerts. The higher the dBZ, the stronger the rainrate. Current weather updated multiple times per hour. Future radar to see where severe weather is headed. 250 meter radar, the highest resolution available. Typically, light rain is occurring when the dBZ value reaches 20. The KATC Weather App includes: Access to station content specifically for our mobile users. The scale of dBZ values is also related to the intensity of rainfall. KATC Investigates Submit a News Tip Around Acadiana Covering Louisiana Acadia Parish Power Doppler HD Acadiana View. The value of the dBZ depends upon the mode the radar is in at the time the image was created. Unidentified driver dies in fiery crash on LA Hwy.

Notice the color on each scale remains the same in both operational modes, only the values change. Doppler 10 Daily Weather Forecast SIGN UP NOW. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Each reflectivity image you see includes one of two color scales. The dBZ values increase as the strength of the signal returned to the radar increases. Acadiana's weather pattern will move into a more unsettled phase as the main regional weather-maker will be festering near the Northern Gulf of Mexico for. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Radar Forecasts Rivers and Lakes Climate and Past Weather Local Programs Click a location below for. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). "Reflectivity" is the amount of transmitted power returned to the radar receiver. The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. The KATC Power Doppler 3000 provides extremely accurate weather readings in a wide range of weather conditions.
