...Advanced Hydrologic Prediction Service (AHPS) long range
probabilistic outlook for the Sabine River basin of East Texas...


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...the Sabine River near Mineola
Texas flood stage is 14 feet.  There is a 50 percent chance the
Sabine River will rise above 16.4 feet during the next 90 days.


        Chance of exceeding stages at specific locations
               valid for March 18 - June 18 2015

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:  http://ahps.srh.weather.gov/index.php?wfo=shv
(internet address URL is all lower case).

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