Gulf disturbance could become 2026’s first named storm, Arthur, bringing heavy rain to Houston
TL;DR
A disturbance over northeastern Mexico has a 50% chance to become a tropical storm in the Gulf, potentially late Tuesday into Wednesday as Arthur—the first named storm of 2026. The bigger risk is prolonged heavy rainfall for Southeast Texas, with a Flood Watch in effect through Thursday and forecast totals of 3–7 inches (locally higher). Rain rates could reach 2–4 inches per hour in bands, creating the potential for flash flooding; stay weather-aware and avoid flooded roads.
