We are monitoring two disturbances, one in the Gulf and the other east of the Caribbean (Remnants of Dolly). The system in the Gulf has become better organized and has a 50% chance of development as it drifts WNW over the next few days. It is expected to bring an increased chance of showers and storms on Tuesday, as well as an increased risk of heavy rainfall and flash flooding.
Atmospheric conditions are expected to be favorable for producing high levels of ozone pollution across the Houston, Galveston, and surrounding areas through Sunday evening, creating conditions that are considered unhealthy for sensitive groups. To help mitigate these levels, residents are encouraged to limit driving or carpool when possible. Furthermore, those planning outdoor activities are advised to restrict them to the early morning or late evening hours to avoid peak pollution times.
Hot and humid conditions continue. Highs range from 96-100°F inland and 92-94°F on the beaches. Heat indices will range from 102-107°F. Isolated storms are possible throughout the day with the highest chances being this afternoon into the evening. Expect SE winds of 5-10 mph, and locally higher gusts around any storms.
Sunday Night’s Outlook: Warm and muggy conditions persist for the Houston/Galveston area. Overnight low temperatures are forecast to be 74-78°F inland and 75-82°F at the beaches. Patchy fog is possible around sunrise, accompanied by light and variable winds. Data updated on August 30, 2026.
