ForecastEx lists contracts on how many named storms and how many hurricanes form in the Atlantic season, how many major hurricanes form in a month, whether specific category storms make landfall in the United States, and major hurricane landfall by region.
While a storm is active, ForecastEx also lists its flagship Live Hurricane wind gust contract at population centers in the storm’s path and a contract on which location records the highest wind gust of the storm.
Wind gust probabilities at the exchange’s reference locations, delivery by delivery, the peak gust each one recorded once the storm has passed, and the pool contract’s prices through the storm.
National Hurricane Center positions, intensities and five-day wind speed probabilities for each storm in this ocean.
The forecaster’s reasoning for each active storm, as issued.
Each count product gets one panel. On the left, how many have formed this season against the pace of an average season. On the right, the price of the Yes contract at each count, read across the same vertical axis. The blue line is the 1991–2020 formation calendar in the NHC best tracks, scaled to the seasonal forecast total where one is published; the dashed line is that calendar unscaled, an average season.
Yes prices by date, drawn against how often a season has produced a Category 4 landfall by that date.
Yes prices by region, for states, counties and countries, on a landfall at Category 3 or stronger. The contract names no ocean, so a region that faces both, as Mexico and Honduras do, is priced on the Atlantic view and the Pacific one.
