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.
