When there is an alert sent out, the text associated with it has been teaching us new terms. It could be that folks who live in these areas are quite used to these terms, but they are new for us.

| "20 Foot winds..." |
I found this on a National Weather Service site:
http://www.nws.noaa.gov/forecasts/wfo/definitions/defineWind20ft.html
20ft winds: Is defined as sustained winds averaged over a 10 minute period and measured 20 feet above the average height of nearby vegetation. This is the standard reported by the Remote Automated Weather Stations(RAWS) owned by land management agencies and used in the National Fire Danger Rating System (NFDRS).

| The rest of the alert for Roswell and areas around. |

| "Hydrologic Statement" |
This is the website it referenced:

This is what the map looks like at this time (when there is a "Hydrologic Statement" for the Shreveport area):
