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. Galveston, TX traffic updates reporting highway and road conditions with live interactive map including flow, delays, accidents, construction, closures,traffic jams and congestion, driving conditions, text alerts, gridlock, and driving conditions for the Galveston area and Galveston county.

Notice the color on each scale remains the same in both operational modes, only the values change.

Weather Today Weather Hourly 14 Day Forecast Yesterday/Past Weather Climate (Averages) Currently: 88 ☏. 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.
Each fully-furnished suite offers a private balcony for you to relax and enjoy the view as well as a small living area with a newly remodeled studio kitchen. The dBZ values increase as the strength of the signal returned to the radar increases.

Live From Casa del Mar 6102 Seawall Blvd., Galveston, TX ( Directions) The Seawall Cam is located on Casa Del Mar Beachfront Suites, ideal for a family vacation or a weekend getaway for two. 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.
