Please consult your device documentation for instructions. Check out NOAAs National Weather Service data for the main Hawaiian Islands. ![]() On mobile devices, you can save the bookmark as an easy-access icon similar to other apps. The Doppler weather radar is used to identify the location of precipitation (rain) and is one of the most important instruments for meteorologists to track a storm. For example, if you select "Weather for a location," then select a location, the bookmark will return to your location on your next visit. Click on the Layers menu in the bottom right of the radar to select radar options like Current Conditions, Storm Tracks. You may bookmark the URL to return later to the same view with the selected settings. Track rain, storms and weather wherever you are with our Interactive Radar. The URL will automatically update as you select the view and settings. Now 11p Map Options Layers and Styles Specialty Maps Make your map your own. This view provides a full map view of all alert hazards (similar to WWA map). Show Low, AZ Radar Map Rain Frz Rain Mix Snow Show Low, AZ Slight chance of rain over the next 6 hours. This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This view combines radar station products into a single layer called a mosaic and storm based alerts. This view provides specific radar products for a selected radar station and storm based alerts. Rainfall Storm Total Doppler Radar for Surprise AZ, providing current static map of storm severity from precipitation levels. 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.This site is organized into views that provide relevant radar products and weather information for a common task or goal. Yuma/Martinez Lake and Vicinity/Lower Colorado River Valley AZ: AZZ132: Central Deserts: AZZ133: Southern Gila County/Tonto National Forest Foothills: AZZ137: Yavapai County Valleys and Basins: AZZ138: Oak Creek and Sycamore Canyons: AZZ139: Black Mesa Area: AZZ140: Northeast Plateaus and Mesas South of Hwy 264: AZZ150: Pima-South Central Pinal. Hail is a good reflector of energy and will return very high dBZ values. ![]() Mostly cloudy with a 30 percent chance of thunderstorms in the evening.partly cloudy after midnight. Light winds becoming southwest around 15 mph in the afternoon. Near steady temperature in the upper 70s. Base Reflectivity Doppler Radar for Mesa AZ, providing current static map of storm severity from precipitation levels. These values are estimates of the rainfall per hour, updated each volume scan, with rainfall accumulated over time. Partly cloudy late in the morning then becoming mostly cloudy. 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. 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). Each reflectivity image you see includes one of two color scales. 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. ![]() infoTodays and tonights Phoenix, AZ weather forecast, weather. Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). Check out our current live radar and weather forecasts for Phoenix, Arizona to help plan. "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.
