chatgpt interpretation:
He is saying that the large-scale tropical pattern is likely to become more favorable for storm formation around Central America, the eastern Pacific, and perhaps the southwestern Gulf of Mexico during roughly October 720.
And importantly, this isn't just one guy reading tea leaves. NOAA's official Week 23 Global Tropics Outlook issued September 29 says essentially the same thing: it expects continued East Pacific activity, sees models developing a Central American Gyre, and assigns a 2040% probability of tropical cyclone formation in the Bay of Campeche/western Caribbean region.
What this means for Houston
At this stage, it does not mean "a hurricane may hit Houston." It's much farther upstream than that.
Think of the forecasting chain as:
favorable large-scale pattern > thunderstorms increase > low pressure forms > tropical cyclone develops > steering pattern determines where it goes
What is worth paying attention to is that the Bay of Campeche/southwestern Gulf may become an area to watch during roughly the second week of October. If an actual disturbance forms there, then the position of ridges/troughs over the U.S. becomes extremely important for whether it stays in Mexico, moves west toward Texas, or gets pulled north/northeast.
