Note:  	NOAA INL weather alerts/statements are analogous to NWS watches/warnings.  Statements are issued 
       	because weather conditions are forecast to become favorable to occur.  Alerts are issued because 
       	weather conditions are imminent or already occurring, and/or significant.   NWS watches/warnings 
       	will always supersede any NOAA INL weather alert/statement. However, NOAA INL weather alerts/
       	statements may be issued at any time to give additional weather information regarding the INL.
