San Antonio and parts of South Texas are under a patchwork of weather advisories today, and people in Bexar County and surrounding communities are being urged to stay alert. KSAT’s weather desk flagged multiple warnings affecting different neighborhoods and counties, and local officials are reminding residents to plan for sudden changes. This article walks through what those notices mean, who’s at risk, and practical steps to stay safe around the city and region.
The first thing to know is that “advisory” is not the same as “warning.” Advisories point to expected impacts that can disrupt daily routines, while warnings mean dangerous conditions that require immediate action. That difference matters when deciding whether to delay travel, protect property, or check on vulnerable family members. Expect varied language across jurisdictions, with some counties upgrading or downgrading their notices as conditions evolve.
The region is currently juggling several types of alerts: flash flood advisories, high wind notices, and heat-related advisories among them. Each of those affects different people in different ways — low-lying neighborhoods feel floods, drivers face wind hazards, and outdoor workers deal with rising heat stress. Agencies coordinate, but local conditions can change block by block, so look for updates from county emergency management and trusted local reports.

Flood advisories are the most immediate concern in low-lying parts of San Antonio and nearby river valleys. If you live near arroyos, creeks, or drainage ditches, have an evacuation route in mind and avoid driving through standing water. Vehicles can be swept away by surprisingly shallow floodwater, and homes with basements or ground-floor entries are most vulnerable to quick rises.
High wind notices are cropping up along open stretches and elevated corridors, threatening unsecured outdoor items and light structures. Secure patio furniture, trampolines, and signs, and move vehicles away from trees where possible. For drivers, be cautious with high-profile vehicles and be ready for sudden gusts that make steering difficult on bridges and overpasses.
Heat-related advisories also affect the metro area, especially where shade and cooling are scarce. Hydration, frequent breaks, and access to air-conditioned spaces are key for anyone working or exercising outdoors. Check in on older neighbors and those with medical conditions because heat illness can escalate fast and quietly.
Power outages are likely in some zones as conditions worsen, so gather basic supplies now: flashlights, a battery radio, extra water, and a charged phone power bank. If you or someone in your household relies on medical devices that need power, contact local health services about backup plans or cooling centers. Many community centers and libraries open as temporary refuges during extended outages.
Commuters should expect delays and detours and plan trips with extra time. Road crews may close flooded streets without notice, and high winds can topple trees onto lines and lanes. Employers often allow flexible hours during advisory periods, so consider remote work or staggered schedules to avoid peak hazard windows.
Schools and childcare programs will watch conditions closely and sometimes alter schedules or close if safety is compromised. Parents should keep contact information updated and have a pickup plan with designated adults in case early dismissal becomes necessary. For outdoor events and youth sports, organizers should err on the side of caution—the risk to kids in heat or sudden storms isn’t worth a tight game schedule.
Pets and livestock need attention too: make sure animals have shade, water, and a cool place to shelter. Bring small pets indoors during storms and secure larger animals in sturdy enclosures. If evacuation becomes necessary, have an animal plan and carriers ready so no one is left behind in a rush.
Finally, stay informed but don’t panic. Local emergency management and broadcasters will update advisories as conditions change, and small adjustments—like postponing a drive or securing loose items—reduce the likelihood of damage. Keep phones charged, heed official instructions, and check back frequently for the latest status in your neighborhood.
