Oh yeah, dusty.

Take a few plastic bags big enough to keep the radio in when you're not
using it. The radio will need ventilation when being used, especially
in hot places. I've used large Tupperware type containers in snowy and
rainy places to keep rigs dry, it'd work for dust and critters.

Humid: If it's too wet, it's too wet. Sometimes letting the radio warm
up will drive out moisture, unless it's really hot and humid.
