What will be the name of the first hurricane in the Atlantic this year?

What's driving it

• • Cristobal's 50% odds imply the market expects an early-season Gulf or western Caribbean system to become a hurricane before any Cape Verde wave earns an 'A' or 'B' name, a scenario that occurred in 2020 when Cristobal became the third named storm but not a hurricane.
• • The near-0% odds on Arthur and Bertha suggest the market sees a very low chance of a named storm forming in the typical 'A' or 'B' window (June–early July) and reaching hurricane strength, consistent with the 2024 season where no hurricane formed until Beryl in late June.
• • Dolly at 22% is the only non-Cristobal name with meaningful odds, likely reflecting the possibility that a late-forming 'D' storm could become the first hurricane if earlier systems remain tropical storms, as happened in 2011 when Dolly became the first hurricane in late July.

What to watch

• • The release of the National Hurricane Center's August outlook (typically around August 1–4) could shift odds toward Cristobal if it highlights Gulf development potential, or away if it emphasizes Cape Verde activity.
• • Any tropical disturbance in the Gulf of Mexico or western Caribbean that is designated as a potential tropical cyclone (PTC) by the NHC in the next two weeks would likely push Cristobal odds above 50%, as it would signal a near-term named storm.
• • A named storm forming in the eastern Atlantic (e.g., a tropical storm named Arthur) would collapse Cristobal's odds toward zero, as it would indicate the first hurricane will likely come from a Cape Verde system.
