A Tropical Storm Warning has been issued for the southwest coast of Florida, stretching from East Cape Sable to Bonita Beach, as Potential Tropical Cyclone 4 moves closer to the state, according to the National Hurricane Center.

Additionally, a Tropical Storm Watch is in effect for the Florida Keys south of the Card Sound Bridge, including the Dry Tortugas; the southern coast of Florida from East Cape Sable to the Card Sound Bridge; and the west coast of Florida from Bonita Beach to Aripeka.

The system, previously known as Invest 97, has been upgraded to Potential Tropical Cyclone 4 as it approaches. While the tropical wave over southeastern Cuba has shown minimal change, it is generating 25-30 mph winds over the southeastern Bahamas and tracking westward across Cuba. Although there is no organized circulation yet, the system could develop into a tropical cyclone over the Straits of Florida by Saturday evening or Sunday, prompting the upgrade.

Models now predict a track closer to Florida, reducing the risk of a Gulf Coast impact and potential hurricane development. A turn back into the Atlantic next week seems likely.

Reconnaissance planes are scheduled to fly over the Long Island Bahamas at 4 p.m. to search for any developing circulation, which could elevate the system to a Tropical Depression. NOAA will also conduct a P-3 flight near Andros Island later tonight to enhance forecast accuracy.

Saturday is expected to be a decent beach day, though by the evening, the system will bring 20-25 mph gusts and frequent showers to the Florida Keys. Rain and breezy conditions are anticipated to intensify on Sunday evening, with heavier rain possibly continuing into Monday.

The GFS ensemble model predicts the system will remain below 40 mph as it moves through Florida, potentially affecting areas from the Keys to the west coast. Rapid intensification into a hurricane seems unlikely due to moderate wind shear and insufficient mid-level moisture. However, intensity models suggest it could reach hurricane strength when it moves into the Atlantic offshore the Carolinas by Tuesday, with any threat to the First Coast having passed by then.
