16 Sep
Summary
- Steamy conditions persist with feels-like temps reaching low 100s.
- Expect gusty winds up to 20 mph and scattered thunderstorms.
- A low-pressure system in the Atlantic has a 30% chance of development.
As of Wednesday, September 16, 2026, South Florida is facing a steamy start to the day with temperatures feeling like the low 90s. Highs are predicted to reach the low 90s again this afternoon, with humidity making it feel closer to the upper 90s and low 100s.
Winds are increasing from the east, potentially reaching 15 to 20 mph by the afternoon and evening, with higher gusts possible overnight. Scattered thunderstorms are also anticipated later today, bringing the possibility of heavy downpours and lightning.
Swimmers heading to Atlantic beaches should be aware of a moderate risk of rip currents due to the onshore flow. Caution is advised, and swimming near lifeguards is recommended. Boaters currently have no alerts or advisories for Atlantic or Keys waters.
The chance of rain is increasing for Thursday and the remainder of the week, as deeper moisture and an upper-level low-pressure system move in. Daily scattered to numerous storms are expected through the weekend.
The CBS Miami Next Weather team is monitoring a low-pressure area in the Atlantic, located several hundred miles east of Bermuda. Conditions may become more favorable for development in the coming days as the system moves slowly westward. The National Hurricane Center has assigned this system a low potential, a 30% chance, of developing over the next seven days.
