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. The animated weather radar view of Hillsborough and Pinellas counties in Florida, including Tampa Bay, St. 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. See the latest United States Doppler radar weather map including areas of rain, snow and ice. 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. gov > Tampa Bay Area, FL Current Hazards Current Conditions Radar Forecasts Rivers and Lakes. Notice the color on each scale remains the same in both operational modes, only the values change.
