The rain stopped, the sun even came out for a while, and recovery was well underway until it was deja vu. The rains came again, bringing a repeat performance. It won't be over if more rain comes, and you can bet it will. Of course, never plug in an electrical appliance while standing in water. Don't even touch one.
Electricity easily runs through water, and charged water can be lethal.
If you can find a dry spot, stand on it and turn the power off with a wood stick. If you're in any doubt, have this done by a professional. This will prevent rising water from shorting out a water heater or furnace burner. Many electrical appliances, including washers and dryers, can survive inundation if allowed to dry out thoroughly. Some may have to be disassembled and cleaned, but not all.
