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.
