    We've noticed a huge increase in rants and negative posts that revolve around agencies going to encryption due to the broadcasting of scanner audio on the internet. It's now worn out and continues to be the same recycled rants. These rants hijack the threads and derail the conversation. They no longer have a place anywhere on this forum other than in the designated threads in the Rants forum in the Tavern.

I'm sitting here listening to my PRO-96 and State Police, Lafayette just put out a broadcast from NWS stating that a Tornado Watch was in effect for 24 northern Indiana counties until 2100 EDT today. I jumped on NOAA and found NOTHING indicating this. We are in the "no risk" catagory. How often is this updated? Am I looking at the wrong thing?

Here is the NWS home page, it shows the national watch and warning map. It does show a tornado watch for much of northern Indiana, southern Michigan, and northwest Ohio.


Click in your area and it will bring you to your local NWS page.

The Storm Prediction Center shows the area in a slight risk for severe weather.

You have several options for finding out the details of a Tornado Watch.

As previously offered, weather.gov and spc.noaa.gov will give you good detail about tornado watches.

What I do in Jacksonville, FL is:

1. Keep your local National Weather Service office as a bookmark/favorite.
For me, it's http://www.srh.noaa.gov/jax
That gives you an overview map, with a legend, and would highlight the counties with watches, warnings, etc.
Use weather.gov to find your local area office.

2. Keep the Storm Prediction Center office as a bookmark/favorite
That's the link (given already) http://www.spc.noaa.gov
Here you will find details about each Watch, Mesoscale Discussion, and a Severe Weather Outlook for today, tomorrow, and the upcoming week.
Each convective watch (e.g., Severe Thunderstorm, Tornado) is issued a number. The numbering system starts Jan 1st with 0001 and continues ad infinitum.
Each watch that is issued has associated probabilities of tornadoes, hail, and wind damage.
Explore the site, it's packed full of current and archived data!!!
Also, you can look back in time to see what/where Watch #001 was, etc.
They, too, keep a log of severe weather events.....more fun!!!
