Antecedent moisture conditions are highly affected by preceding rainfall levels. However, preceding rainfall is not the only condition that affects antecedent moisture, and many other variables in the hydrologic process can have a significant impact.
The amount of moisture present before an event is heavily impacted by the amount of rain that has fallen previously. However, it's important to note that this isn't the only factor influencing antecedent moisture; many other variables within the hydrological cycle can have a significant impact.
