The writer asked "do you know what frequency the skywarn net is here in Houston. There are some tornado warnings".
How would you answer?
RepeaterBook lists Skywarn repeaters. It is a popular list.
Always check with your local Weather Service Office. For help finding your local office, go to Weather dot GOV and enter your zip code. That will get your local forecast. Nets are listed in the Skywarn section of the page.
There are also nets on 40 and 20 meters.
