Tropical Weather Outlook July 22, 2020

Tropical Storm Gonzalo was named Wednesday morning as a second tropical disturbance is being monitored in the Gulf of Mexico.

Two developments have popped up on the National Weather Service's Lake Charles office radar — including one that could creep into the Gulf of Mexico later this week.

A series of tropical waves have lined up across the tropical Atlantic, Caribbean and Gulf of Mexico this week, and triggered the rain Southwest Louisiana experienced early Tuesday. The next in the series is expected to be moving into the Gulf today. The National Hurricane Center gives the wave a 40 percent chance of development over the next four days.

Another tropical system is developing out in the Atlantic with an 80 percent chance of developing and maybe given a name later this week. The next names on the list for 2020 are Gonzolo and Hanna.

"Should this storm be named any time in the next four days — or three days, I should say — this will be the ... quickest that we've gotten to the ‘G'-name storm if either one of these systems receive that name," said meteorologist Donald Jones.

The last fastest was in 2005 with Hurricane Girk, Jones said.

The biggest impacts for these tropical disturbances will be higher-than-normal rain chances and elevated tides today and Friday.

"The most immediate threat is going to be the tropical wave that is presently located in the western Caribbean Sea," Jones explained.

Rainfall could go up to almost 2 to 3 inches of rain, but can increase should the storm become "better organized," Jones said.

Going into the weekend, the best-case scenario shows Southwest Louisiana being on the northeast side of the storm with heavy rainfall. The recent dry spell will allow the moisture to better soak into the ground, hopefully slowing any chances of flooding unless the storm worsens, Jones said.

"I think by Thursday we're going to start to see the impacts as far as rainfall from this system," he said. "The more spread out the rain is, the better off we'll be."
