Hurricane Isaias continues to strengthen move northeast, approaching the Central Gulf. Hurricane warnings are currently in effect from Ocean Springs, Mississippi, to the Bay/Gulf County line in Florida. The system is forecast to turn northward and make landfall along the northern Gulf Coast tonight. Consequently, no significant impacts are expected for Southeast Texas, though increasing winds, swells, and rip current risk in Gulf waters are anticipated through the early weekend along with potential minor coastal flooding. You can continue to monitor for updates.
A Small Craft Advisory is in effect for the High Island to Matagorda Shipping Channel (0-60 NM) on October 9, 2026, through 1 AM CDT Saturday. Hazardous wind and wave conditions are expected, with nearshore seas of 4 to 6 feet, offshore seas of 6 to 9 feet, and northeast winds of 10 to 20 knots with gusts up to 25 knots in the open Gulf. Inexperienced mariners, especially those operating smaller vessels, should avoid navigating in these conditions. The advisory covers multiple locations across the region and is issued by the National Weather Service Houston/Galveston.
Minor coastal flooding will be possible today in Galveston and Bolivar due to water levels nearing 3.5 Feet above normal. Most likely time frame of minor coastal flooding will be during high tide this afternoon. Strong rip currents are likely as well.
An Air Quality Alert and Ozone Action Day have been issued for Saturday, October 10, 2026, by the National Weather Service Houston/Galveston. Atmospheric conditions will be favorable for producing high levels of ozone pollution in the Houston, Galveston, and surrounding areas through Saturday evening, resulting in conditions that are unhealthy for sensitive groups. Residents are encouraged to limit driving, carpool, and schedule outdoor activities for early or late in the day to minimize exposure and emissions.
Tonight features comfortable and less humid conditions. Low temperatures will range from 63 to 71 degrees Fahrenheit inland and 68 to 75 degrees Fahrenheit at the beaches. The night will feature low humidity and generally dry conditions inland, though a few light showers remain possible along the coast.
