These scans are interpreted by a computer and translated into an image. A complete set of scans takes around 5 minutes to complete. 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).

A weather radar is used to locate precipitation, calculate its motion, estimate its type (rain, snow, hail, etc. 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. The Current Radar map shows areas of current precipitation. 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. View LIVE satellite images, rain radar, forecast maps of wind, temperature for your location. 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. The radar map is updated every 5 minutes with a new radar observation. Click the dot of any active station to display current radar. Click Local Radar to see the location of radar stations. Use the Layers window to change the base layer or add other boundaries. If the energy strikes an object (raindrop, snowflake, bug, bird, etc), the energy is scattered in all directions. The weather radar (United States) shows where it is currently raining or snowing. View radar the contiguous United States, or search, zoom, and pan to an area of interest. The radar emits a burst, or pulse, of energy. Got radar?

We added new features to the radar viewer based on feedback we received from the public and emergency management community. The webpage is more reliable now that it's on an operationally supported system 24/7. The new page’s infrastructure allows for easy integration of new datasets, like satellite imagery, in the future and See the latest Oregon Doppler radar weather map including areas of rain, snow and ice.
