KEY MESSAGES

Updated at 711 AM EDT Mon Aug 10 2026 - A Heat Advisory is in effect today for Miami-Dade, Broward, Palm Beach, and Collier Counties.

- 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 start the work week.

SHORT TERM

(Today through Tuesday) Issued at 303 AM EDT Mon Aug 10 2026

Deep-layered high pressure centered over the Atlantic will continue to hold influence over Florida with the ridge extending into the eastern Gulf. Light easterly to southeasterly surface wind flow over the area continues through the week. The Gulf sea breeze will develop and advance inland each day allowing for a convective focus zone over portions of Southwest Florida and inland South Florida. Drier air will remain over the region the next few days which will help lower convective coverage, particularly over Southeast Florida.

Maximum temperatures will reach the lower to mid 90s each day under more abundant sunshine. 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 Miami-Dade, Broward, Palm Beach, and Collier Counties. Experimental Probabilistic HeatRisk depicts a substantial 50+ percent swath of the Dade/Broward/Palm Beach western suburbs and central urban heat island away from the immediate coast with major HeatRisk today. Palm Beach County has some values exceeding 90 percent in some cases along the State Road 7/US 441 corridor. Collier County, particularly around Marco Island, has similar with 70+ percent chances of Major HeatRisk.

LONG TERM

(Tuesday night through Sunday) Issued at 303 AM EDT Mon Aug 10 2026

A drier Saharan Air Layer settles in Wednesday into Thursday 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. This moisture will allow convective activity to trend closer to seasonal norms based on the current forecast guidance. Another round of drier could emerge late in the weekend to close out the long term forecast period.

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 720 AM EDT Mon Aug 10 2026

Generally VFR with L/V flow through around 15Z, then SE winds around 10kt prevail. Only exception will be APF where a westerly flow will develop after 16Z due to the Gulf breeze. Brief periods of MVFR?IFR cigs/vis are possible over APF this afternoon. VFR and L/V flow returns tonight at all terminals.

MARINE

Issued at 303 AM EDT Mon Aug 10 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 303 AM EDT Mon Aug 10 2026

Persistent easterly to southeasterly wind flow will allow the rip current risk to remain elevated through a good portion of the week along the Atlantic beaches.
