Key takeaway Chance around San Antonio is only 20%, but a little higher closer to the coast because of Tropical Storm Bertha.
Why this matters in The San Antonio
The scorching heat index in San Antonio today is a stark contrast to the flooding still affecting areas along the Nueces and Frio Rivers, where nearly 500 billion gallons of water from last week's rains are slowly draining. As Cotulla and Tilden continue to deal with major flood stages, the city's own flood mitigation efforts will be put to the test if the predicted spotty showers materialize. With a 20% chance of rain in San Antonio, residents should remain vigilant and check the latest forecasts before heading outdoors. Meanwhile, the weak Tropical Storm Bertha may bring some relief to coastal areas, but its impact on San Antonio's weather will be minimal. As the city navigates this complex weather landscape, residents can stay informed through local weather resources, such as the KSAT Weather Authority App, to plan their daily activities and stay safe.
