Tropical Weather Outlook -- June 14th, 2021 Update

Click HERE and HERE for an update on the tropics.

Changes from previous update: 

  • The chance of development in the western Gulf of Mexico over the next 5 days has increased to 70%.

  • Confidence continues to increase that very heavy rainfall will occur in southeast Louisiana and south Mississippi, so a preliminary forecast rainfall graphic has been included.


There is a LOW (20%) chance of tropical cyclone development over the next 2 days.  

There is a HIGH (70%) chance of tropical cyclone development over the next 5 days.  


  • This system could impact the northern Gulf Coast region late this week and over the weekend, and although there is high uncertainty on any specific impacts this far out, the greatest concern at this point remains heavy rainfall and the potential for flooding.
  • Preliminary rainfall forecast amounts are expected to mostly range from 4-10 inches with some areas possibly seeing greater than 10 inch amounts. We emphasize this is preliminary, and amounts could shift lower or higher depending on the exact track, size and speed of movement of the tropical system.
  • Now is the time to review preparedness plans since we are only in the beginning of hurricane season.

The attached graphics hyperlinked above highlight the likely development area and the preliminary rainfall forecast.
