The NWS Radar page and NWS Satellite page also are available. The URL should auto-update with the current settings, allowing for an easy bookmark/favorite. 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). See the latest United States Doppler radar weather map including areas of rain, snow and ice. To toggle the lower-left menu visible/hidden, click the ≪ or ≫ button. See the latest Northeast Regional Doppler weather radar map including areas of rain, snow and ice on. 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. rise unless there were swarms passing over at the time ) in cloudy weather. On the GeoColor satellite images (GOES-West/East cutoff at -114°) the pale bule areas are nighttime areas of lower clouds. The flight was from northeast to north on northerly winds 57 to 79. The radar, lightning, visible satellite, IR satellite, GeoColor satellite, SIGMETs/CWAs, and flight categories/weather can be toggled on/off. 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.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. 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. 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). Nome, North Slope, Northwest Arctic, Petersburg, Prince Of Wales-Hyder, Sitka, Skagway.

Northwest US 1800-Mile Doppler Radar 1 Map Northwest US Doppler Radar Current rain and snow in the Northwest US. The dBZ values increase as the strength of the signal returned to the radar increases. View weather map showing precipitation in the northeast US with an 1800 mile doppler radar. So, a more convenient number for calculations and comparison, a decibel (or logarithmic) scale (dBZ), is used. Wind direction is SSE at 5 mph 8 km/h with visibility of 10 mile(s) mi 16 km.

Reflectivity (designated by the letter Z) covers a wide range of signals (from very weak to very strong). 1 Map Shows current cloud cover with the white and grey areas representing cloud cover. "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.
