Will the North Atlantic basin, including the Caribbean Sea and Gulf of Mexico, produce a tropical or subtropical cyclone?

🤖 Context

YES if at any time between 00:00 UTC on August 10, 2026 and 23:59:59 UTC on August 20, 2026 an operational advisory or an official best-track shows a system inside the North Atlantic basin (north of the equator, including the Caribbean Sea and Gulf of Mexico) classified as a tropical depression, tropical storm, hurricane, subtropical depression, or subtropical storm. Retroactive official best-track reanalysis that establishes such a classification inside the window also counts as YES. Model 'invest' labels, informal social media claims, or media reports without an official advisory do not count. Otherwise NO. Resolution sources include the U.S. National Hurricane Center, the World Meteorological Organization, or a national meteorological service.
