Severe thunderstorms and dangerous flash flooding is likely across the Gulf Coast States on Saturday. A strong surface low will develop just off the Texas coast near Galveston early Saturday and track across southern Louisiana, southern Mississippi, southern Alabama and into central Georgia. A well-defined cold front associated with the surface low will track eastward across the area, triggering a line of severe storms. Abundant moisture ahead of the front will lead to widespread rainfall of 2 to 3 inches with isolated amounts of up to 4 inches in some locations. In addition to flash flooding, mid- and upper-level winds will be favorable for isolated tornadoes, some violent/strong, across the region.

LOCATIONS
A strong storm system will move across the Gulf Coast states on Saturday. The Storm Prediction Center has the following areas in a slight risk area on Saturday:

  • extreme southeastern Texas (including Galveston),
  • southern Louisiana (including New Orleans),
  • southern Mississippi and southern Alabama (including Mobile, Dothan),
  • southern and central Georgia (including Columbus) and the
  • western Florida Panhandle (including Destin, Panama City and Tallahassee).

PRIMARY THREATS
The primary threat will be dangerous flash flooding, damaging thunderstorm winds and tornadoes.

TORNADOES/TIMING

  • southeastern Louisiana, including New Orleans, during early- to mid-afternoon hours,
  • coastal sections of Mississippi and Alabama, including Biloxi and Mobile, during the mid- to late-afternoon hours, and
  • the extreme western Florida Panhandle, including Destin during the early evening hours.
