Remnants of Cindy are Spreading Heavy Rainfall From Lower Mississippi Valley into Ohio Valley

June 23,2017
Cindy was a tropical storm that brought days of heavy rainfall from the Gulf Coast northward into the Ohio and Tennessee valleys, and continues to spread rain from the lower Mississippi Valley into the Ohio Valley.
Moisture and energy from the remnants of Cindy are spreading north and east ahead of a cold front into Saturday, which will result in heavy rain and possible flooding from the South to as far north as the Ohio Valley and mid-Atlantic.

Isolated tornadoes and heavy rain will continue to be possible through Friday evening.
NOAA's Storm Prediction Center has issued the following severe weather watches:
  • A tornado watch valid until 10 pm EDT for portions of eastern Kentucky. This watch area includes Lexington and Hazard, Kentucky. 

What's Happening Now

Satellite and radar imagery show shower and thunderstorm activity in parts of the South, Ohio Valley and Northeast. The remnants of Cindy are located in central Kentucky, and they will continue northeastward into the central Appalachians.

Current Radar and Alerts
The remnants Cindy will continue to move into east-northeastward into the central Appalachians late Friday bringing very heavy rainfall.
Here's a rundown of the timing and impacts for Cindy.
  • Friday: Heavy rain from Cindy will continue in the lower Mississippi Valley into the Ohio Valley, but moisture from the storm will also spread north and east ahead of a cold front arriving from the Midwest. This could contribute to locally heavy rain and flooding in parts of the Ohio Valley and the central Appalachians. 
  • Additional rainfall of 1 to 2 inches, with locally higher amounts, is possible through Friday.

Impacts and Summary

Cindy developed from a monsoonal low-pressure system near Central America. A heavily sheared tropical low-pressure system moved northward into the Gulf of Mexico and became a tropical storm.
The tropical storm strengthened and expanded as it moved northward. On June 21, winds increased to 60 mph and tropical-storm-force winds expanded to more than 250 miles from the storm's center.
Wind gusts of 45 to 55 mph were clocked along the Alabama, Louisiana and Mississippi coasts June 20-22.
Cindy made landfall as a tropical storm on the northern Gulf Coast between Cameron, Louisiana, and Port Arthur, Texas, early Thursday, June 22 with maximum sustained winds of 40 mph.

Tropical Storm Cindy made landfall early Thursday morning along the Gulf Coast.

In the days following Cindy's landfall, the storm's circulation combined with a cold front dropping south from the Midwest and Plains produced numerous tornadic circulations from Florida to Pennsylvania including one EF2 tornado near Birmingham.
Cindy washed out as a tropical depression in central Kentucky after traveling through Louisiana, Texas, Arkansas and Tennessee mainly as a rainmaker.
The highest rainfall amount so far is 18.74 inches near Ocean Springs, Mississippi. Here are a few select rainfall totals:
  • Alabama: 8.29 inches in Mobile; 4.35 inches near Tuscaloosa
  • Arkansas: 4.86 inches near DeWitt
  • Florida: 10.70 inches in Navarre; 9.47 inches near Pensacola; 8.14 inches near Panama City Beach
  • Georgia: 7.51 inches near Rocky Plains; 6.85 inches in Starrsville
  • Louisiana: 10.49 inches near New Orleans; 6.92 inches in Pearl River; 4.63 inches near Baton Rouge
  • Mississippi: 18.74 inches near Ocean Springs; 14.40 inches in Gulfport
  • Texas: 5.36 inches in Mahaw Bayou; 3.35 inches in Sabine Ranch; 2.90 inches near Galveston
Radar estimated rainfall from June 20-22, 2017.
