NHC tracking Tropical Storm Humberto, Invest 94L. Spaghetti models. Naples, Marco Island impact?

Tropical Storm Humberto formed in the Atlantic Sept. 24. A second tropical systems, Invest 94L, is expected to develop further and could become the next named storm of the 2025 hurricane season, according to the latest advisory from the National Hurricane Center.

The next named storm of the 2025 hurricane season will be Imelda.

Tropical Storm Humberto is located several hundred miles east of the Leeward Islands and likely to become hurricane in the next 72 hours.

The second system, Invest 94L, is a tropical wave in the southeastern Caribbean Sea and expected to bring heavy rainfall and gusty wind into Puerto Rico and the Virgin Islands today and across the Dominican Republic beginning tonight.

Invest 94L is then expected to slow down and turn northwestward when it reaches the southwestern Atlantic in a couple of days. A tropical depression is likely to form late this week or on the weekend when the disturbance is in the vicinity of the Bahamas.

An Air Force Hurricane Hunter Aircraft is en route to perform a system survey.

Interests in the Virgin Islands, Puerto Rico, the Dominican Republic, the Turks and Caicos Islands, and the Bahamas should monitor the progress of this system.

Hazardous beach and marine conditions could develop along portions of the Florida East Coast from Invest 94L later this week and into the weekend.

While neither system is expected to pose a direct threat to Florida at this time, the hurricane center will continue to watch them closely. Officials encourage residents to always be prepared.

While it’s too soon to tell if these systems will have any impact on the Naples area, the National Weather Service’s weather forecast for the next two days includes daily chances for rain and thunderstorms, with temperatures in the low 90s and heat index values above 100 degrees.
