Why this matters in The San Antonio

As Tropical Storm Bertha moves toward the Florida Panhandle and Alabama, San Antonio residents should be aware of the potential for heavy rain and flash flooding in the coming days. Although the storm is expected to stay near the northern Gulf Coast, its trajectory westward toward Texas could bring significant rainfall to the area. With the storm surge watch and tropical storm warning in effect for parts of Louisiana, Alabama, and Florida, it's likely that the effects of Bertha will be felt in San Antonio, particularly in terms of increased rainfall. The National Hurricane Center's prediction of 3 to 5 inches of rainfall along the Louisiana coastline, with higher amounts in some areas, suggests that San Antonio could see similar amounts of rain, potentially leading to flash flooding. Residents in low-lying areas should be prepared for possible flooding and stay informed about the storm's progress.
