KEY MESSAGES

Updated at 644 AM EDT Sun Aug 9 2026 - Scattered showers and thunderstorms expected in the afternoon, focused over the interior and Southwest Florida.

- Persistent easterly winds will maintain an elevated Rip Current risk along the Atlantic beaches to close out the weekend.

- A Heat Advisory is in effect from late morning into the early evening for the Dade/Broward metro area. A Moderate HeatRisk is expected across the eastern half of South Florida and western Collier County today.

SHORT TERM

(Today through Monday) Issued at 135 AM EDT Sun Aug 9 2026

Deep-layered high pressure centered over the Atlantic will continue to hold influence over Florida with the ridge extending into the eastern Gulf in the wake of an inverted trough. This will keep a light easterly to southeasterly surface wind flow over the area to close out the weekend and kick off the work week. The Gulf sea breeze will likely develop and advance inland each day allowing for a convective focus zone over portions of Southwest Florida and inland South Florida.

Temperatures will continue to be on the warm side with highs reaching the lower to mid 90s each day. Maximum heat index values will range from the lower 100s to the lower 110s, depending on the area. Accordingly, a Heat Advisory will be in effect from mid- morning into the early evening for the Miami-Dade and Broward metro area. Will allow the next shift to monitor the morning warm up in case this needs to be expanded to additional areas. Experimental Probabilistic HeatRisk depicts a substantial 50+ percent swath of the Dade/Broward western suburbs and central urban heat island away from the immediate coast with major HeatRisk today and Monday. Similar is the case for portions of Collier County as well.

LONG TERM

(Monday night through Saturday) Issued at 135 AM EDT Sun Aug 9 2026

A drier Saharan Air Layer moves in Tuesday into Wednesday as the ridge axis slides a bit further north along the peninsula of Florida. This will allow for the easterly to southeasterly wind flow to persist while the lower relative atmospheric moisture will provide lower convective coverage focused inland in the afternoons. The dry air will linger until late in the week when the next burst of tropical moisture begins to arrive from the Bahamas and Greater Antilles Friday into Saturday to close out the week. This moisture will allow convective activity to trend closer to seasonal norms based on the current forecast guidance.

Given the relative decrease in showers and storms forecast for a good portion of the long term forecast period, temperatures will begin a warming trend with lower to mid 90s becoming the story across much of the area. Triple digit heat index values are forecast and the potential for Heat Advisories will need to be monitored day- to-day, particularly over the urbanized areas.

AVIATION

(12Z TAFS) Issued at 644 AM EDT Sun Aug 9 2026

Scattered showers along the east coast metro this morning and then scattered showers and storms across the interior and SW FL this afternoon into early evening. SE winds 10-15 kts, with an afternoon westerly Gulf breeze at APF.

MARINE

Issued at 135 AM EDT Sun Aug 9 2026

Gentle to moderate east-southeasterly winds will persist across the local coastal waters through the next few days. Isolated to scattered thunderstorms remain possible each day, which may result in locally gusty winds and brief periods of rough seas. Outside of convection, seas will generally remain 2 to 3 feet.

BEACHES

Issued at 135 AM EDT Sun Aug 9 2026

Persistent easterly to southeasterly wind flow will create another elevated rip current risk today along the Atlantic beaches. The rip current risk may remain elevated through a good portion of the week along the Atlantic beaches.
