Hi Beth,
"情况"的范围要比"状况"大一些,有时可以通用。“情况”has a larger range than "状况",sometimes they can be interchangeable. But "状况" emphasize on the current status now.
Here are some examples for these two phrase:
◎情况
1. 根据具体情况而定。
It depends on the specific situation.
2. 一有情况你就要立即报告给老板。
You should report to your boss immediately if something happened.
◎状况
1. 他的家庭经济状况不太好。
The economic situation of his family is not good.
2. 大多数中国老人的身体状况都很好。
Most of the Chinese old people's health situation is good.
I hope these answers are useful for you.
