Should not be a problem, GM and other have spend a lot of $$ on R&D for those connections and parts.
I have cleaned some of my older car engine by just spraying it down with Gunk Engine cleaner and then just hosing it off.. I has always started up and ran for me.
But as jmm98ls1 stated, blow or dry off what you can if your really concern about it.

Uh... After loosing an engine possibly due to a rain storm I'd absolutely advise against starting it right away. I'd try and dry it off / let it dry. Pull the plugs and turn it over by hand in an attempt to get any water that could have possibly gotten in there out.

For all those saying just start it up, I agree somewhat because your only option is to take the intake off. You might want to know that water does seep between the heads and the intake thru the headbolt groves (see bottom pic), the front under the intake and the back under the intake. All of it goes onto the valley cover.
Now, that by itself would normally not be a problem if the rubber seals did a good job of sealing the knock sensors up. Unfortunately, heat causes seals to dry up and shrink leading to loss of the seal. Once that happens, if enough water that get's in there, it will puddle and reach the knock sensors and they will rust and eventually die. See pic below.
When I put my 408 in, I made damn sure the knock sensors were sealed good with plenty RTV before putting the intake on. See 2nd pic.
A tarp is always a good idea, no matter what the weatherman says. And it's inexpensive. Live and learn...

I routinely cleaN MY ENGINE WITH the green goo and a garden hose. i have done this with many cars for years - no issues if you are not spraying down the intake or directly on the pcm.
...let it dry a while since the rain my have soaked the pcm... that is the risk.

Fire it up. You wont have anything to worry about especially if your running a stock lid, because by some act of god the rain would hafta get under the lid then make a verticle leap through your airfilter and continue upward until it gets out of the lid. Point being your not going to injest any water so you wont have problems. FWIW my car sat ouside of a body shop with no hood and a half *** rigged up stock air induction system for over 6 months, through rain sleet snow shine and thunderstorms. You will be fine.

I pressure washed my engine once and managed to get some sensor wet, which ended up making my starter engage while driving down the street, or just never disengage from starting it lol. Will that stop me from washing my engine bay in the future? No, but ill prolly not use the high pressure washer on it.

Wait till those rubber seals dry out in your car.
