THIS LONG-RANGE PROBABILISTIC OUTLOOK CONTAINS NUMBERS THAT ARE
CALCULATED USING MULTIPLE SCENARIOS FROM 50 YEARS OF HISTORICAL
CLIMATOLOGICAL AND STREAM FLOW DATA. THESE NUMBERS ALSO TAKE
INTO ACCOUNT CURRENT CONDITIONS OF THE RIVER AND SOIL MOISTURE.
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 EXPLANATION ARE AVAILABLE ON THE
INTERNET AT: HTTP://AHPS.SRH.WEATHER.GOV/INDEX.PHP?WFO=FWD
(INTERNET ADDRESS IS ALL LOWER CASE).
LONG-RANGE PROBABILISTIC OUTLOOKS ARE ISSUED AROUND THE THIRD
