Several sources we consulted, Jesse, say that your pumpkins will be ok, esp this late in season and esp if they are strong and healthy otherwise. Dampness is not the best thing. Spraying, esp with rain coming that may wash off the spray, may not be the best solution. If you do want to spray, consult a nursery about horticultural oil of a biological fungicide.
In future, consider planting resistant varietes, give the plants plenty of room to grow, and certainly full sun.
Here's hoping you get this before the rains!
