![]() 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. Typically, light rain is occurring when the dBZ value reaches 20. The scale of dBZ values is also related to the intensity of rainfall. 75 6 mph W 75 Humidity 18 ☏ Dew Point 18 ☏ Comfort Level 10 mi Visibility 30.12 in Barometric Pressure Real-time Pollen & Air Quality Current Time : 02:31 AM MST Nearest / Estimated. The value of the dBZ depends upon the mode the radar is in at the time the image was created.

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). Previous Locations-Reporting Station : Evanston-Uninta County Burns Field, WY. Each reflectivity image you see includes one of two color scales. 79 22 mph SW 79 Humidity 25 ☏ Dew Point 18 ☏ Comfort Level 10 mi Visibility 29.83 in Barometric Pressure Real-time Pollen & Air Quality Current Time : 3:10 PM MST Nearest / Estimated. The dBZ values increase as the strength of the signal returned to the radar increases. Previous Locations-Reporting Station : Evanston-Uninta County Burns Field, WY. 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. South Australians should play their part in preparation for a hot and dry bushfire season ahead, authorities say as the state recorded its second warmest winter in history.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. 66 18 mph WSW 66 Humidity 17 ☏ Dew Point 10 ☏ Comfort Level 10 mi Visibility 30.26 in Barometric Pressure Real-time Pollen & Air Quality Current Time : 7:43 PM MST Nearest / Estimated.
