The Forecaster

 is a psychic child living under the bridge at 188 Trading Post in 2281.

Background
The Forecaster lost his parents a long time ago, and has been on his own since, but he's gotten used to it.

Other interactions
You can offer to buy his headgear but he will refuse.

You can pay him 100 caps to "hear his thoughts" on "You", "Here", or "Everywhere". He is basically a fortune teller.

You: Your face does the thinking - two to the skull, yet one gets up. Odds are against you... but they're just numbers after the two-to-one. You're playing the hand you've been dealt, but you don't let it rest, you shuffle and stack, and a gamble... a gamble that may pay off? But how? Forecast: Rapidly changing conditions. A lot of think- most of it in your face. It's almost shouting at me. Sorry if I said anything weird.

Here: Local, local, the here and now... little of interest.. things to buy, false hopes, and regrets watered down, washed down in dirty glasses. With regret comes a girl... smiling sad,brown robe, name Veronica, half here. Wraps her and her heart up like a pack, in the pack, a key, some say. Forecast: Cloudy, with a chance of friendship.

Everywhere: Bull and Bear over the Dam, at each other's throats... but a light from Vegas? Ball spinning on the wheel, more then two at the table. Placing bets. All lose in different ways. A dam of corpses, towns of corpses, scattered across the sand. But whose in what shares? Even the dealer doesn't know. Forecast: A rain of blood will flood the desert and not purify it.

Bugs
Addition/correction: you will get stuck in the ground not far from Black Mountain, in the place where you met Neil. On PC, with the use of console command you can get to the road (the nearest solid ground where it is possible to stay and move normally). There will be a large amount of texture, clipping, and object interaction bugs in the area. You may see a supermutant master and few centaurs stuck in the rocks, one of the satellite dishes may fall down… If you travel a short distance from the place (say, to the nearest road post and a little further) and then come back, you'll see that all glitches are gone. (The crashed satellite dish will remain there constantly.)
 * On the PC Patch 1, the Forecaster can be seen floating in mid-air a few inches off the ground instead of on the ground in his sitting pose.
 * If you try to kill the forecaster with the sandman perk enough times, you may end up being transported to an irradiated part in the wasteland with no means of escape. (Confirmed PC and PS3.) (A note from this readers/writers, this is probably not a bug, but a glitching feature.)

Appearances
appears in Fallout: New Vegas.
