Saturday we'll see peak conditions and some cooling is expected especially at the coast on. Hail is a good reflector of energy and will return very high dBZ values. The warming trend continues Saturday with 70s and low 80s at coastal valleys and low 90s in the interior. 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. hall and library to trick-or-treaters KSBY Santa Barbara-San Luis Obispo, CA. Use the + or at the top right to zoom in. By finger pressure or mouse click you can move the area on the map. With the cursor at the bottom left in the center you can view the weather over time. Typically, light rain is occurring when the dBZ value reaches 20. View live doppler radar, snow totals, closings, and alerts from the WAVY. The weather radar live itself displays cloud cover, current precipitation, storms, thunderstorms or tornados in real-time. 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). Check the latest weather conditions, get location-specific. Each reflectivity image you see includes one of two color scales. You can also view current severe weather warnings & watches for Monterey on the KSBW alerts page. 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. 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.
