Updated forecast for weekend of September 14

The National Hurricane Center has updated the predictions to 70 percent chance of tropical storm development in the Gulf of Mexico.  Currently the tropical clouds have not developed into a named storm; however, conditions exist for the further activity and development before the storm reaches the Texas coastline.  

This tropical event will produce heavy rainfall even if the clouds do not develop into an organized storm. The updated forecast from the National Hurricane Center is listed below.

“A broad area of low pressure is located over the central Gulf of Mexico. Although the shower activity is still disorganized, upper-level winds are forecast to become more conducive for development, and it is likely that a tropical depression will form Thursday or Thursday night, before the system reaches the western Gulf coast.  An Air Force Reserve Hurricane Hunter aircraft is scheduled to investigate the disturbance tomorrow, if necessary. Regardless of development, heavy rainfall and gusty winds are expected across portions of northeastern Mexico, Texas, and Louisiana late this week.”

The National Weather Service has updated the forecast for the San Antonio area to include: 

“Showers and thunderstorms are expected Thursday through Tuesday. Heavy rains become more widespread Friday into Saturday resulting in a greater threat for flash flooding and possibly renewed river flooding. Rainfall amounts of 2 to 4 inches will be possible with isolated totals up to 8 inches. Due to recent rains and the saturated ground even a quick 1 inch of rainfall could lead to flash flooding issues in some areas. The area of greatest concern for the heavy rainfall and potential flash flooding will be across the Rio Grande, western Hill Country and San Antonio metro areas. Chances and coverage of rainfall will begin to decrease during the first part of next week.”
