Usage Note
falls is a subordinating conjunction meaning 'if / in case', so it sends the verb to the end of its clause: falls es regnet. It stresses a condition that may or may not happen, slightly more tentative than wenn. Don't confuse it with the adjective falsch (wrong).
Examples
"Falls es regnet, bleiben wir hier."
Natural Translation
If it rains, we'll stay here.
Literal Translation
In-case it rains, stay we here.
