Houston woke up inside a cloud early Monday, February 9, 2026, as dense fog wrapped around much of the metro area and chopped visibility down to about a quarter mile in spots. The National Weather Service hoisted a Dense Fog Advisory through 9:00 a.m. CST, with an early morning that felt more like late spring than winter, thanks to unusually mild temperatures in the upper 50s to low 60s, near-saturated humidity and light south-southwest winds.
Dense Fog Advisory And Commute Tips
The National Weather Service issued the Dense Fog Advisory at 5:31 a.m. CST, flagging visibility of one-quarter mile or less and warning of hazardous driving conditions for the morning rush. Drivers are urged to slow down, stick to low-beam headlights and leave extra room between cars. Expect slower speeds and longer commutes through mid-morning as the fog hangs on. For the official advisory details and safety guidance, see NWS Houston/Galveston.
Afternoons Warm, Midweek Shower Chance
The thick morning fog should mostly burn off by mid-morning, flipping the script to mostly sunny afternoons. Highs will top out near 78°F on Monday and stay in the upper 70s for much of the week. South winds will generally run light at 5 to 10 mph, although a weak disturbance on Tuesday could nudge gusts up to around 20 mph. That system also brings a slight chance of showers and isolated rain from late Tuesday into Wednesday morning. Forecast guidance does not point to widespread heavy rain.
Sea Fog And Boater Notice
Out along the coast, sea fog is likely to form over Galveston Bay and nearby Gulf waters overnight and could linger into the afternoon in some coastal spots. That may tangle up launches and ferry schedules. Mariners should be ready for low visibility and use running lights, radar and proper fog signals while underway. Operators of small boats may want to delay nonessential trips. Forecasters note a nightly sea-fog setup at least through mid-week if light winds and sticky air hang around.
Where To Check
If you are heading out, build in extra time for the morning drive and be ready for slowdowns on major routes. For live traffic flow and lane-closure updates, check Houston TranStar, and keep an eye on the National Weather Service for any changes to advisories. We will pass along any new alerts or timing shifts as they come in later this week.
