Radio towers (and some other things) continuously transmit a predetermined radio message you can pick up with a radio. You can determine direction to the transmitter with a directional antenna. One of the broadcasts is a weather radio station that gives accurate-ish weather forecasts.
I should totally put a “pile of straw” next to the tower, give you a “climb” command to get to the top, and a “leap from tower” command once you’re at the top.
And kill you when you jump into the pile of straw, because that’s not enough to protect you from a fall from that height.
