MISSISSIPPI RIVER FROM LAKE CITY..MINNESOTA TO
LOCK AND DAM 10 AT GUTTENBERG..IOWA
LONG-RANGE PROBABILISTIC OUTLOOK
NATIONAL WEATHER SERVICE
NORTH CENTRAL RIVER FORECAST CENTER TWIN CITIES/CHANHASSEN MN
155 PM CDT MON OCT 20 2014

IN TABLE 1 BELOW...THE CURRENT (CS) AND HISTORICAL (HS) OR NORMAL
PROBABILITIES OF EXCEEDING MINOR...MODERATE...AND MAJOR FLOOD STAGES
ARE LISTED FOR THE VALID TIME PERIOD.

CS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY
BASED ON CURRENT CONDITIONS.

HS VALUES INDICATE THE PROBABILITY OF REACHING A FLOOD CATEGORY
BASED ON HISTORICAL OR NORMAL CONDITIONS.

WHEN THE VALUE OF CS IS MORE THAN HS...THE PROBABILITY OF
EXCEEDING THAT LEVEL IS HIGHER THAN NORMAL. WHEN THE VALUE OF CS IS
LESS THAN HS...THE PROBABILITY OF EXCEEDING THAT LEVEL IS LOWER
THAN NORMAL.
