While redevelopment of Tropical Depression Four remains unlikely, the shell of the system will spread showers and thunderstorms across South Florida prior to the end of the week."The former tropical depression will remain poorly organized, but moisture associated with the system will bring locally heavy showers and thunderstorms to South Florida and the Keys on Thursday," according to AccuWeather Hurricane Expert Dan Kottlowski.
Much of the showers and thunderstorms precede the actual old center of the former depression. This activity will affect the Bahamas into Thursday.
"The best chance for torrential downpours along the Atlantic coast counties will be during early Thursday morning," according to AccuWeather Meteorologist Maggie Samuhel.
"The storms will migrate slowly westward on Thursday and Thursday evening," Samuhel said.
Some of the thunderstorms can be a bit more robust, when compared to most storms in the summer.
There is the potential for localized urban and low-lying area flooding.
Those spending time outdoors should keep an eye out for rapidly changing weather conditions.
Boaters should be alert for sudden changes in the sea condition as locally gusty squalls are possible.
Bathers should use caution due to an anticipated increase the strength and number of rip currents along the Atlantic coast, due to a stiff easterly breeze.

Otherwise, the rainfall may be beneficial for the southeastern counties, where rainfall has been lean during the first part of July.
While the former depression will wander into the Gulf of Mexico this weekend, development is still unlikely. The same system may bring an uptick in showers and storms to part of the Texas coast later in the weekend.
Strong winds at mid-levels of the atmosphere and large pools of dry air and dust will likely prevent or greatly limit tropical development in the Atlantic basin into next week. This includes another batch of showers and thunderstorms projected to reach the Leeward Islands by Friday and the Caribbean Sea this weekend.
