ALT Tropical Weather Outlook map issued by the National Weather Service Houston/Galveston at 12 PM on August 30, 2026. The graphic displays a 50% chance of tropical formation for a system south of Louisiana that may form over the next few days as it drifts west-northwestward. A note clarifies that the shaded area on the map represents where the disturbance may form and is not a track forecast cone. The graphic also notes a 20% chance of development for the remnants of Dolly over the next 7 days. Forecast impacts include an expected increase in the chance of showers and thunderstorms by Tuesday, with locally heavy rainfall possible. The outlook concludes that it is too early to know if Dolly's remnants will reach the Gulf and advises the public to monitor weather.gov/houston for updates.
