What do the warnings mean?
A first degree warning means that the water levels (observed or forecasted) are in the zone below the warning states, with a possible sudden increase.
A 2nd degree warning means that water levels (observed or forecasted) are in the zone above the warning states but below the alarm states.
A warning state is announced when water levels are very high, almost to the point of overflowing. An alarm state is announced when water begins to threaten farmland and water constructions. The alarm state is the basis for the announcement of a flood alarm.
