The National Hurricane Center is monitoring Tropical Storm Cindy in the Gulf of Mexico.

Rip currents, high surf, isolated tornadoes and some coastal flooding are also possible.

Tropical Storm Cindy has formed in the Gulf of Mexico, and it will be a soaker and flooding concern for parts of the South through late this week.

Gusty winds, rip currents and isolated tornadoes are also expected.

A tropical storm warning has been issued from High Island, Texas, to the mouth of the Pearl River. Tropical storm conditions are expected within 36 hours. A tropical storm watch is in effect from west of High Island, Texas, to San Luis Pass, Texas, which means tropical storm conditions are possible within 48 hours.

Tropical storm conditions are expected to first reach the Louisiana coast within the warning area by Tuesday afternoon. These conditions are possible within the watch area Wednesday.

Satellite imagery shows vigorous shower and thunderstorm activity in the northern and eastern Gulf of Mexico. That stormy weather is located mainly to the north and east of the low-pressure center, which is over 200 miles south of Morgan City, Louisiana.

Cindy is expected to move north to northwest and reaching the Louisiana coast late Wednesday.

It's important to not focus completely on the forecast path of the low-pressure center since impacts will extend well to the east along the Gulf Coast.

Parts of southeast Louisiana, southern Alabama, southern Mississippi and the Florida Panhandle are not in the forecast path but are expected to see a substantial amount of rain, which could cause flooding.

Another ingredient in this soaking setup is a stalling frontal boundary in the South that will also provide a focus for locally heavy rain.

Florida was the first area to experience this influx of moisture, resulting in heavy downpours on Monday. The northern Gulf Coast will see heavy rain from Cindy Tuesday through Thursday.

This heavy rain could eventually lead to flash flooding and river flooding in some areas.

What To Know

  • The heaviest rain amounts are likely to be on the northern Gulf Coast, including parts of southeast Louisiana, southern Mississippi, southern Alabama and the Florida Panhandle.
  • This swath could see 6 to 9 inches or more of total rainfall by Thursday. Locally extreme rain amounts of 12-plus inches could occur in localized areas, according to the NHC.
  • Flash flooding and river flooding are both possible threats.
  • Other parts of the South, including the Florida Peninsula, will also see locally heavy rain at times this week due to the abundant moisture and stalling front. Heavy rain could occur as far west as southeast Texas through Thursday.
  • The rain could linger into Friday.
  • A high risk of rip currents is likely along parts of the Gulf Coast. High surf and some coastal flooding are also expected. Inundations of 1-3 feet are possible in the tropical storm warning area.
  • Gusty winds are likely near parts of the northern Gulf Coast this week, particularly north and east of where the low tracks.
  • An isolated tornado is also possible through Tuesday night from south-central Louisiana to the western Florida Panhandle.
