Update 8 p.m.: The weak low-pressure area over Florida is interacting with an upper-level low to produce a large but disorganized area of cloudiness and showers extending from the northwestern Caribbean northward through most of the state, according to the National Hurricane Center in Miami.
Environmental conditions appear to be marginally conducive for some additional development before the upper-level winds become unfavorable early next week, according to the center’s 8 p.m. tropical weather outlook. The chance of a tropical system forming over the next five days is 40 percent.
Regardless of development, the system is likely to produce locally heavy rainfall over portions of western Cuba, the Florida Keys, and the Florida peninsula during the next several days while the system moves northwestward to northward, according to the NHC. The next tropical outlook will be issued at 2 a.m.
