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.78201 WEATHER WARNINGS (SEVERE T-STORM & TORNADO) 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. Leone Program Manager Sterling Software P P MARYLAND Office of Planning 1120 San Antonio Road Palo Alto CA. Professor and Chair of Emergency Medicine at UT Health. The value of the dBZ depends upon the mode the radar is in at the time the image was created. SAN ANTONIO Medical staff is warning people heading outdoors to pace themselves and pay attention to their bodies to prevent heatstroke.

First Alert Weather Radar LIVE RADAR: Watch our KENS 5 First Alert Radar as the thunderstorm system makes its way into San Antonio. 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. See the latest Texas Doppler radar weather map including areas of rain, snow and ice. 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. ![]()
