![]() ![]() ![]() 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. 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 higher the dBZ, the stronger the rainrate. Our interactive map allows you to see the local & national weather. Live interactive radar with many layering options. See the latest New York Doppler radar weather map including areas of rain, snow and ice. Then, set customized alerts to keep you and your family informed and safe. With its easy to use interactive radar, you can take control and see where the storm is now and where it is tracking. Typically, light rain is occurring when the dBZ value reaches 20. The WPRI Weather app utilizes the most advanced radar maps, weather and digital technology available. The scale of dBZ values is also related to the intensity of rainfall. ![]() The value of the dBZ depends upon the mode the radar is in at the time the image was created. Notice the color on each scale remains the same in both operational modes, only the values change. The other scale (near left) represents dBZ values when the radar is in precipitation mode (dBZ values from 5 to 75). RadarScope (Android, iOS: 9. 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. Have you ever wondered why there is that small spot at the center of our Klystron 9 radar that is always blank Theres a good scientific reason all weather. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Read details Now 3p Map Options Layers and Styles Specialty Maps. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Pinpoint Doppler One Hour Loop Regional Satellite/Radar Loop Pinpoint Doppler North Pinpoint Doppler South. Hourly 10 Day Radar Winter Erie, PA Radar Map Rain Frz Rain Mix Snow Erie, PA Small Craft Advisory until TUE 10:00 PM EST. "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. ![]()
