THE NATIONAL WEATHER SERVICE IN BROWNSVILLE HAS ISSUED A
* SEVERE THUNDERSTORM WARNING FOR...
CENTRAL ZAPATA COUNTY IN DEEP SOUTH TEXAS.
* UNTIL 100 PM CDT
What type of warning is it, who is it for, when does it expire and where did it come from?
The * is there to help software, such as at TV and radio stations read the warning automatically.
Also warnings can be re-issued after they expire, so just because it's 1:00 p.m. doesn't always mean the threat is over!
