The amusement park, along with Zoo America, was closed Monday because of the weather.
The park tweeted Monday morning that the decision was made because of the excessive rainfall over the last three days and localized flooding.
"Hersheypark is slated to resume operations tomorrow, Tuesday, July 24, as scheduled at 10:00 a.m., barring any unforeseen weather changes overnight. Please note ZooAmerica will remain closed. Our team continues to watch conditions closely and will post updates here," the amusement park tweeted Monday evening.
