Why this matters in The San Antonio
San Antonio's potential triple digit temperatures this week will put a strain on the city's water usage, even as the Edwards Aquifer and area lakes continue to rise. The aquifer's level, now above 650 feet for the first time since 2022, is a welcome sign after years of drought, but the impending heat wave will likely lead to increased water consumption. Residents can expect to see higher water bills if they aren't mindful of their usage. Meanwhile, the tropical system brewing in the Gulf, potentially to be named Bertha, may bring some relief from the heat, but its impact on the city is expected to be minimal. As the system moves towards South Texas, residents should still be prepared for potential changes in the weather forecast and take necessary precautions to stay safe during the hot summer days ahead.
