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. Kvoa-Tv Tucson, AZ Doppler Radar Weather - Find local Kvoa-Tv Tucson, Arizona radar loop and radar weather images. 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. The NOWRAD Radar Summary maps are meant to help you track storms more quickly and accurately. Notice the color on each scale remains the same in both operational modes, only the values change. The Current Radar map shows areas of current precipitation. 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). Data collected using Doppler radar polarimeteric technology are objectively analyzed by complex precipitation. 3-Day Infrared Satellite Loop 3-Day Water Vapor Loop (Color) Regional Satellite Loops. High resolution and interactive rainfall data on Google Maps. Each reflectivity image you see includes one of two color scales. Radar-estimated precipitation accumulation for the past 24 hours to 3 days. Wind 11 mph ENE Precip 4 Sunset 7:12 PM Moon. Yuma, AZ Doppler Radar Weather - Find local 85364 Yuma, Arizona radar loop and radar weather. The dBZ values increase as the strength of the signal returned to the radar increases. See the latest Arizona Doppler radar weather map including areas of rain, snow and ice. Hilo 73F Fair Feels like 73 Wind 4 mph N Humidity 79 Sunrise 5:48 AM Sunset 7:12 PM Tonight 71F Partly cloudy. Interactive Tucson, AZ weather map allows for personalized. 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). Tucson, AZ Doppler Radar Weather - Find local 85701 Tucson, Arizona radar loop and radar weather images. "Reflectivity" is the amount of transmitted power returned to the radar receiver. This page will be updated to a more robust version including PIREPs by the end of April.The colors are the different echo intensities (reflectivity) measured in dBZ (decibels of Z) during each elevation scan. The NWS Radar page and NWS Satellite page also are available. Weather Underground provides local & long-range weather forecasts, weatherreports, maps & tropical weather conditions for the. The URL should auto-update with the current settings, allowing for an easy bookmark/favorite. Arizona Weather Radar More Maps Radar Current and future radar maps for assessing areas of precipitation, type, and intensity Currently Viewing RealVue Satellite See a real view of Earth. Īdditional URL parameters include lt (center latitude), ln (center longitude), zm (zoom level, 0-12), nolabel (removes flight category icon ID labels), hidemenu (hides the menu options on the lower left), wide (thicken US state boundaries), county (include US counties and other political boundaries based on zoom level), hidefir (hide FIR boundary), zseareas (add the ZSE ARTCC areas), and start (UTC start date/time, YYYYMMDDhhmm format, AWC data goes back up to 2 days, GLM data up to 5 hours). To expand the radar map, keeping the menus/options above and legend below, click ⟺ (include "&invert" in the URL to reverse the background/text colors). To toggle the lower-left menu visible/hidden, click the ≪ or ≫ button.
Left-clicking on the "Speed" area will slow the loop and right-clicking will accelerate the loop, ranging from 0.05 to 5 second interval. When both the flight category and weather are displayed, the flight category icon will be on the inside and the partially-transparent weather color on the outside.Ĭlicking on the map will start/stop the loop. Also, GeoColor images may occasionally miss a frame or two. On the GeoColor satellite images (GOES-West/East cutoff at -114°) the pale bule areas are nighttime areas of lower clouds. The radar, lightning, visible satellite, IR satellite, GeoColor satellite, SIGMETs/CWAs, and flight categories/weather can be toggled on/off.
The above loop uses radar and visible/IR satellite data obtained from Aviation Weather Center (AWC), GeoColor satellite data from NOAA NESDIS-STAR, lightning (GLM) data from NOAA nowCOAST, and observations (for flight category and weather) from MesoWest.
