Tropical Storm Isaias () is a currently active tropical cyclone located in the Bay of Campeche. The ninth named storm of the 2026 Atlantic hurricane season, Isaias originated from a low-pressure area over the southwestern portion of the Gulf of Mexico on October 6.
Meteorological history
On October 3, the National Hurricane Center (NHC) first identified a potential area for tropical cyclone formation, related to a low-pressure area that was expected to develop over the southwestern Gulf of Mexico. Two days later, a trough developed along the Gulf Coast of Mexico, producing an area of thunderstorms. As the system drifted eastward on October 5, it was designated as Invest 92L. The following day as the system became more organized, the NHC increased formation chances to near 100%. Conditions in the gulf included high sea surface temperatures. On October 6 at 21:00 UTC, the system developed a closed circulation and was designated as Tropical Depression Nine. Around that point in time, the system was moving slowly eastward as a result of a trough, and the convection was found mostly to the north. At 09:00 UTC on October 7, the system was judged to have attained tropical storm strength, becoming named Isaias, with a slightly faster movement speed.
