In the table below, the 90 through 10 percent columns indicate the
chance the river could rise above the listed stage levels during
the next 90 days. For example, for the Sabine River near Mineola
Texas, the flood stage is 14 feet. There is a 50 percent chance the
Sabine River will rise above 16.2 feet during the next 90 days.

This long range probabilistic outlook uses probabilities
computed using multiple scenarios from 60 years of historical
climatological and stream flow data. These probabilities also
account for the current river flows and soil moisture conditions.
By providing the complete range of probabilistic numbers, the
level of risk associated with long range planning decisions can be
determined.

Additional supportive data and explanations are available on the
internet at this URL: https://water.weather.gov/wfo/shv (internet
address URL is all lower case).

Long range probabilistic outlooks are issued during the third
Thursday of every month.
