The Multimedia Hazardous Weather Briefing is a product designed to keep you informed of any upcoming hazardous weather. The briefing will be updated as needed, and focus on any potential weather hazards over the next 7 days. Longer range threats such as drought or river flooding may also be discussed. This product will be suspended during severe convective weather events. During those times, you are urged to consult our severe weather summary page for the most timely information.

It may take a few minutes to load.

Spotter activation statement and color-coded guide. For a quick idea of what's expected today, look in the upper left corner to find the spotter activation statement and a color-coded guide. Green means spotter activation is not anticipated, yellow means spotter activation may be needed, and red means spotter activation is likely.

Quick access to the multimedia hazardous weather briefing and the daily weather story. Both the multimedia briefing and the weather story can be viewed right on this page! Clicking the appropriate icon will open a box just like this help page. To return to the briefing page, click the "X" in the upper right corner of the dialog box (not the browser).

Common questions

What is the "spotter activation statement"? The spotter activation statement is taken directly from 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. 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.

The graphics look odd in the "image swap" tab. Lines are jagged or broken, and it's hard to read the text in the lower left corner. What's going on? This is a problem with how Internet Explorer handles image rendering. The graphics look fine in Mozilla Firefox.

I clicked on one of the two pictures below the spotter activation statement, and now I can't click anywhere else on the page. Help! Look for a gray bar with the phrase "Multimedia Hazardous Weather Briefing" or "Daily Weather Story" 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.

The GIS display is broken. Part of the display is grayed out and the controls don't work very well. What happened, and how do I fix it? Sometimes there is a display conflict between the GIS display and the other tabs. To fix it, refresh the page by using the gray refresh button on the upper right side of the web page, or by placing your cursor in the address bar of the web browser and pressing enter. Using your brower's refresh button may not work.

The GIS display doesn't show any storm reports, but several LSRs have been sent out. What's going on? The GIS display uses a file provided by the WDSSII group at the National Severe Storms Laboratory. This file is provided on a non-operational basis and may experience temporary data outages. This is why the GIS display might be empty even if storm reports have been sent out.

I'm not an emergency manager. Can I still use this page? Absolutely! Although this page was developed to meet the needs of emergency managers in our county warning area, it is available for everyone to use.
