![]() ![]() 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. Radar Forecasts Rivers and Lakes Climate and Past Weather Local Programs Click a location below for detailed forecast.

These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. There are 63 areas with 63 active weather alerts.

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. into the U.S., affecting air quality in many areas across the Lower 48. The higher the dBZ, the stronger the rainrate. Check the latest weather conditions, get location.

There are 14 areas with 14 active weather alerts. 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). 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. Interactive weather map allows you to pan and zoom to get unmatched weather details in your local neighborhood or half a world away. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. 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. ![]()
