Hi,  
yes, the alarm stays on if there is still water on the sensor.  
At summer it’s not the problem. It will dry fast. At cold days with high humidity, even due will raise the alarm.  
For normal rain, I put a piece of aluminium tape at the bottom edge. So the water will not stay at the border but drips of.
