Forecasters Still Expect Rain for S.A. Area from Tropical System


  • A broad area of low pressure is producing disorganized shower and thunderstorms activity over the SW Gulf of Mexico Tuesday morning. This system is expected to move slowly northwestward toward the northeastern coast of Mexico, and it could become a tropical cyclone before it moves inland within the next 24 hours. An Air Force Reserve reconnaissance aircraft is scheduled to investigate the disturbance later today, if necessary. 
  • There is a medium (50%) chance for tropical cyclone formation within the next 48 hours in the southwest Gulf of Mexico.
  • Regardless of development, tropical moisture is expected for portions of South Central Texas through Wednesday night, bringing an increased chance for showers and thunderstorms.
  • 1-3 inches of rainfall are forecast through tonight across the western counties. Isolated higher amounts are possible.
  • 1-3 inches of rainfall are forecast through Wednesday near and east of I-35 and I-37. Isolated higher amounts are possible.
  • Isolated Flash Flooding is possible within the higher rainfall amounts.
  • Given the weak and disorganized nature of the system, this is a lower confidence rain forecast and is likely to change depending on the eventual track of the potential system.
