Welcome to Live Weather Radar I am always looking to improve the weather radars on this site. View LIVE satellite images, rain radar, forecast maps of wind, temperature for your location. Doppler radars scan the horizon in 360˚ degrees in a set pattern of angles from very low (along the horizon) to very high (almost straight up). This view is similar to a radar application on a phone that provides radar, current weather, alerts and the forecast for a location. This process of emitting a signal, listening for any returned signal, then emitting the next signal, takes place very fast, up to around 1300 times each second. This view combines radar station products into a single layer called a mosaic and storm based alerts. Computers analyze the strength of the returned pulse, the time it took to travel to the object and back, and the phase shift of the pulse. The radar instrument receives a signal from this reflected energy during its listening period. A small fraction of the scattered energy is directed back toward the radar. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. The coverage of the Pacific Northwest by weather radar is by no means uniform. Our loop shows the signals recorded by several radars in the northwest over the last several hours. The radar emits a burst, or pulse, of energy. High values of dbz (color scale to the right of the image) indicate large drops and heavy precipitation. NEXRAD (Next Generation Radar) stations obtain weather information (precipitation and wind) based upon returned energy.
