Enhanced Data Display. The EDD is an advanced, interactive display that allows users to view real-time weather data including radar data, local storm reports, watches & warnings, current observations, and much more. By default, the EDD on this page is configured for radar, local storm reports, and watches/warnings. To view radar data, click on the white radar ball (NEXRAD site) or the Airplane (Terminal Doppler Weather Radar). The number on the symbols indicate the age of the latest image in minutes.

Common Questions

What is the "spotter activation statement"? The spotter activation statement is created in the Hazardous Weather Outlook (HWO). It is used to let trained weather spotters know approximately when and where they could be needed to help spot severe weather. Training sessions for weather spotters are free of charge and are held several times each year, usually in the early spring and fall. Check this calendar to find a class near you. If you would like to request a spotter talk, please contact us for more information (contact information is at the bottom of this page).

When I first load the web page, it looks strange for a few seconds. What's going on? It's called a "flash of unstyled content", or FOUC. It is completely harmless. It's just an artifact of the computer code that makes the web page work.

I clicked on one of the pictures and now I can't click anywhere else on the page. Help! Look for a gray bar with the phrase "Current Graphicast" on the left side of the bar and an "X" on the far right side of the gray bar. Click the "X" to return to the main briefing page.

I can't view the EDD, or this site doesn't work well with my device. What do I do? Try viewing our basic hazards page.

What don't the graphics or the EDD work? These features are considered experimental. Availability is not guaranteed.
