Will a hurricane form by May 31?

This market will resolve to "Yes" if NOAA designates any storm in the Atlantic a hurricane between December 4, 2025, and May 31, 2026. Otherwise, this market will resolve to "No". The resolution source for this market will be NOAA’s list of named storms during the Atlantic hurricane season (https://www.nhc.noaa.gov/data/tcr/) and/or their data on individual storms. If there is a potential named storm that has not yet been classified by May 31, 11:59 PM ET, the market may remain open until June 1, 12:00 PM ET to determine if a classification was made prior to midnight.
