Tropical Outlook: Atlantic, Caribbean and Gulf Remain Quiet Through August 23

Monday, August 17, 2026

The Atlantic Basin is beginning the week on a relatively quiet note, with no tropical cyclones currently active in the Atlantic, Caribbean Sea or Gulf of America. The latest outlook from the National Hurricane Center indicates that tropical cyclone formation is not expected anywhere across the basin during the next seven days. (National Hurricane Center)

That means residents across Florida, including Marco Island, Naples and the Southwest Florida coast, can begin the week without an immediate tropical development threat. However, it is still the heart of hurricane season, and forecasters will continue watching tropical waves moving westward across the Atlantic.

🌴 Atlantic Ocean: Watching the Tropics

The eastern Atlantic contains a new tropical wave along roughly 17°W, moving westward at about 10 to 15 knots. At this time, the wave is not showing signs of significant organization, and conditions are not expected to support tropical cyclone development during the next seven days. (National Hurricane Center)

For the remainder of the week, the main areas to watch will be the central and eastern tropical Atlantic, where additional waves can emerge from Africa.

Even though development is not expected, tropical waves can still bring increased clouds, showers and thunderstorms as they move westward.

🌀 Caribbean Sea: No Development Expected

The Caribbean is also expected to remain free of organized tropical cyclone development through the next seven days.

Moisture associated with tropical waves may produce periods of heavy rain, thunderstorms and locally gusty winds, particularly across portions of the eastern and southern Caribbean.

For the western Caribbean and Florida Straits, conditions will remain more closely tied to the movement of tropical moisture and the daily pattern of thunderstorms than to any organized tropical system.

🌊 Gulf of America: Quiet Tropical Pattern

The Gulf of America is not currently showing signs of tropical cyclone formation, and the National Hurricane Center does not anticipate development during the next seven days. (National Hurricane Center)

High pressure is expected to remain a dominant feature across the Gulf during the week, with generally slight to moderate seas anticipated. (National Hurricane Center)

For Southwest Florida, that means the primary concern will be the typical summertime thunderstorm pattern, rather than a tropical storm or hurricane.

Afternoon thunderstorms will remain capable of producing brief heavy rain, frequent lightning, gusty winds and locally higher seas.

📅 Seven-Day Tropical Outlook

Monday, August 17: 🌴 Quiet start. No tropical cyclone development expected. A tropical wave in the eastern Atlantic will continue moving westward.

Tuesday, August 18: 🌊 Low tropical risk. Atlantic tropical waves will be monitored, but organization is not expected. Caribbean and Gulf thunderstorms remain the main weather concern.

Wednesday, August 19: ☀️ Generally quiet basin-wide. No tropical cyclone formation expected. Tropical moisture may continue producing showers and thunderstorms in parts of the Caribbean and Gulf.

Thursday, August 20: 🌀 Watching the Atlantic. Additional tropical waves could move off Africa, but there is currently no indication of significant development.

Friday, August 21: 🌦️ Stormy weather remains possible locally. Tropical development remains unlikely, while moisture and thunderstorms continue across portions of the Caribbean and Gulf.

Saturday, August 22: 🌴 No organized tropical threat expected. Forecasters will continue monitoring the Atlantic for emerging tropical waves.

Sunday, August 23: 🔎 End of the outlook period. Current guidance suggests no tropical cyclone formation across the Atlantic, Caribbean or Gulf through this period.

🚨 What Southwest Florida Residents Should Know

For Marco Island and Naples, the message for the week is relatively reassuring: there is no tropical system currently threatening Southwest Florida and no tropical cyclone formation is expected in the basin over the next seven days.(National Hurricane Center)

That doesn’t mean the weather will be completely quiet.

August remains firmly within the peak portion of hurricane season, and conditions can change quickly. Residents should continue monitoring official forecasts, particularly when tropical waves begin moving across the central Atlantic and Caribbean.

For now, however, the tropics are giving Florida a break.

🌴 Tropical Threat Level: LOW

Atlantic: 🟢 Low
Caribbean: 🟢 Low
Gulf of America: 🟢 Low
Southwest Florida: 🟢 No immediate tropical threat
7-Day Tropical Cyclone Formation: 🟢 None expected

This outlook is based on the National Hurricane Center’s tropical weather information available Monday, August 17, 2026. Tropical conditions can change, and residents should monitor the latest NHC forecasts for updates. (National Hurricane Center)
