\nFor each watch, probabilities for particular events inside the watch
\n(listed above in each table) are determined by the issuing forecaster.
\nThe “Low” category contains probability values ranging from less than 2%
\nto 20% (EF2-EF5 tornadoes), less than 5% to 20% (all other probabilities),
\n“Moderate” from 30% to 60%, and “High” from 70% to greater than 95%.
\nHigh values are bolded and lighter in color to provide awareness of
\nan increased threat for a particular event.<\/p>\n<\/div>\n
