What's Happening?

The National Hurricane Center is introducing a revamped track forecast cone graphic for the upcoming Atlantic hurricane season, starting June 1, 2026. This new graphic aims to enhance communication about storm risks and probabilities, addressing previous misunderstandings associated with the 'cone of uncertainty' used since 2002. The updated version includes inland tropical storm and hurricane watches and warnings for the continental United States, Hawaii, Puerto Rico, and the U.S. Virgin Islands, shaded with bright colors to better convey wind risks. The graphic will also be interactive, allowing users to zoom, pan, and save images. The changes are part of a continuous improvement process to ensure the public and emergency managers receive accurate and comprehensive information about potential storm impacts.

Why It's Important?

The new forecast cone graphic is designed to provide a more accurate representation of storm risks, extending beyond the traditional coastal areas to include inland regions. This change is crucial for emergency managers and residents in these areas, as it highlights the potential for high winds and other hazards that can occur outside the cone. The graphic aims to reduce misunderstandings about the storm's size and path, offering a clearer picture of the risks involved. By improving the communication of these risks, the National Hurricane Center hopes to enhance preparedness and response efforts across affected regions.

What's Next?

The updated cone graphic will debut with the first tropical storm of the Atlantic season, which begins on June 1, 2026. The graphic uses ellipses instead of concentric circles to illustrate forecast errors, based on a 90% probability that the storm's center will remain within the cone. This change is expected to provide higher forecast confidence and a better representation of potential storm paths. The interactive version of the graphic will allow users to explore detailed information about storm risks and timing, aiding in more effective planning and decision-making.

Beyond the Headlines

Residents and emergency managers are advised to use the new forecast cone graphic in conjunction with other weather products to gain a comprehensive understanding of storm risks. The National Hurricane Center emphasizes the importance of considering the full range of hazards, including those outside the cone, to ensure effective preparedness and response.
