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

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

CS VALUES INDICATE THE ESP 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 OR HEFS IS MORE THAN HS...THE PROBABILITY OF
EXCEEDING THAT LEVEL IS HIGHER THAN NORMAL. WHEN THE VALUE OF CS OR
HEFS IS LESS THAN HS...THE PROBABILITY OF EXCEEDING THAT LEVEL IS
LOWER THAN NORMAL.
