The electric awnings have an auto dump feature on them all .The lowest side or whichever side goes firest will let the shock go a bit and dump rain water off awning. It will repeat when water weight gets to a certain point . But it is still best to tilt any awning.
It was a rainy few days at Algonquin Prov park...tarps kept us dry.
