Every warning is a market

Three short-fuse calls per warning.

The second the NWS issues a warning, AtmosOption opens three YES/NO contracts on what the cell will actually do — the gust, the hail, the tornado on the ground. Take a side before the clock runs out; they settle on the verified storm report.

Built for atmos & meteorology students

For the people who actually read the models.
