   At what point will they be unharmed by rain running off a garage roof and falling directly on the concrete?

   I wouldn't take a chance with that kind of persistent rainfall tonight, that's for certain.  I'd cover both pads with plastic then carefully lay something on top of the plastic, under the roof edge to deflect the rain water.  A couple of scrap pieces of plywood or whatever you have on hand. 

   I'd also put some weight around the edges of the plastic so they'll stay put.

   you should be fine with just a couple of hours setting time before exposure to rain, it certainly wont weaken the concrete.

   water wont hurt the concrete but the force of water off the roof will, get off your butt

   Be hoping by now you are already doing something to protects it.

   >>> Radar doesn't show any rain in the area currently so it is probably at least a couple hours away.

   You still have time for a few more replies to get a concensus, and have another beer.

   Well even though we never seem to get rain (South Dakota) there is lightening in the South now so I went up and covered the freshest pad almost totally and the older one where the rain off the roof would hit.
   Thanks for the responses.

   I had a floor being poured once, new house, big cellar bottom. Roof not tight, cement guy decides to go for it..... next morning after hellacious downpour ( brief but torrential ) I look in the cellar..... About 20 coffee cups strategically placed wherever the drips came in through the subfloor, and some scrap ply laying under the stairway hole. Floor was perfect.Good thing we drink so much coffee.

   You want to be very careful that water doesn't get under the plastic and sit on the surface of the concrete. If it does you'll likely get blotchy spots that won't go away.

   Hey how's Friday harbor doing these day's?
   I lived on Orcas for Four years. Started to get a bit
   crowded after a while, so I headed back east.
   Friday Harbor gotten much bigger in the last ten years?PS
   Concrete needs twenty four hours to be safe.

   Continuing expansion here, maybe more on SJI than Orcas but I bet it's there too. Sure do love to ride my bike at Moran State Park.

   That's one of the best state parks anywhere.
   When I was living there work was endless, one good
   part of growth anyway.

   If your pads are just footings, it's no biggy, but if, by "pads" you're speaking of a finished surface of some kind, direct rainfall will erode the cream finish on top and you'll get an uneven exposed aggregate finish.

   If that's the case, I'd keep it covered for a couple of days, at least, or until the rain is gone.

   "..you'll get an uneven exposed aggregate finish." Or worse. I have had a couple of instances where steady drops on day old concrete ate holes into the surface. Worst mess with rain and concrete though was a garage approach that endured a deluge off an 8/12 roof all the way across the front of the garage. I had left it covered and the owner pulled the plastic and ply back to open the garage doors. The resulting trench does make for a convenient drain though.
