I meant that these things could happen like freak accidents, occuring once every year or so, and they would be map specific. The tornados would be hilarious to watch, you would see unlucky tankers get scooped up into the air, and you would be killed if you stuck your head out. Forest fires would also be fun.
I can hear the newbies singing now:
"My home base is burining down, burning down, burning down.
"My home base is burning down, curse, you, Skuzzy!"
Maybe a few floods, you know, only for a few weeks. Then they would come back and you would have to rebuild the base. It would help to keep the annoying posts for the B-29 down.
"You have angered the great HiTech, for that, your bases shall be covered for 40 days and 40 nights."

Let's get some meteorites going, too. They would just occasisonally pummel a few sectors of map into an intransverable heap of rubble. They would be 16', yes, not 16", 16' in diameter, and they would have an effective blast radius of one mile. They would come in showers of about 70. If it hit something like a fuel refinery, there would be a toxic cloud of petroleum; if you so much as fired a pilot's pistol in there it would ignite, destroying everything in a huge fireball.
That reminds me, why not have the occasional toxic cloud? They would come from destryoed chemical facilities and choke everything, or explode. They would get you even if you were the tower. There, your charcter would slowly choke to death, unable to move. There would start to be a white light, and HiTech would appear before you. Then you would slowly fall into empty, shadowed, unconcious and deathly darkness.
