statute miles north and south of a line from 40 miles east northeast
of Alexandria LA to 85 miles west northwest of Fort Polk LA. For a
complete depiction of the watch see the associated watch outline

The "Low" category contains probability values ranging from less than 2%
to 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities),
"Moderate" from 30% to 60%, and "High" from 70% to greater than 95%.
High values are bolded and lighter in color to provide awareness of
an increased threat for a particular event.
