![]() 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. We will have good viewing conditions in SWFL with. ![]() Hail is a good reflector of energy and will return very high dBZ values. Live WINK News radar and detailed forecast analysis are available from expert meteorologists in the app. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Two formations have increased the odds of a tropical development from 20-30 within the next 2-7 days in the Central and Eastern Atlantic. 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. Typically, light rain is occurring when the dBZ value reaches 20. 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). Dubbed WINK Doppler 3X, the radar is the billed as the most powerful in the. One scale (far left) represents dBZ values when the radar is in clear air mode (dBZ values from -28 to +28). Live Doppler radar for Southwest Florida from our local tower in Fort Myers. 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. ![]() So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Interactive weather map allows you to pan and zoom to get. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). We’re dedicated to bringing you up to the minute information on weather, breaking news and more. The new WINK Doppler 3X radar provides the most powerful, sophisticated technology in the area. "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.
