A tropical feature will sweep across Florida and the Bahamas with enhanced downpours and rough surf into the middle of the week.

The feature of interest, dubbed 92L, is a disorganized cluster of showers and thunderstorms located northeast of Puerto Rico. A continued track to the northwest is expected over the next few days.

The chances of 92L becoming the next tropical depression or storm of the 2017 Atlantic hurricane season remain low.

“Ninety-two L is expected to remain in a strongly sheared environment for the next several days,” AccuWeather Hurricane Expert Dan Kottlowski said. “So, the potential for further development looks low at this time.”

Wind shear, or the change in wind speed and direction with altitude, can prevent disorganized features from developing and shred apart mature tropical systems, as was the case with Harvey.

“Regardless of development, this system will bring gusty winds and downpours into the Turks and Caicos Islands, as well as the southern Bahamas on Monday,” Kottlowski said.

Hispaniola and Cuba could also face an increasingly wet pattern as 92L sweeps to the north.

“Downpours will arrive over the rest of the Bahamas on Tuesday, then into southern Florida Tuesday night and Wednesday,” Kottlowski said.

A separate tropical feature will bring heavier-than-normal thunderstorms to the Florida Peninsula into Monday. This feature has lost its opportunity to develop.

Enhanced surf and rip currents will progress northwestward with the storm. Boaters and beachgoers should exercise caution and heed all advisories.

Rainfall associated with 92L could be heavy enough to trigger flash and urban flooding.

A strong front diving across the Southeast late in the week could interact with 92L and further enhance torrential rainfall across the Sunshine State. Motorists and airline travelers should expect an increase in delays toward the middle and latter half of the week.

Should 92L beat the odds and strengthen to a tropical depression or storm, downpours, gusty winds and rough surf would be enhanced even more.

Another area of disorganized showers and thunderstorms located about 1,000 miles east of the Leeward Islands will likely be steered to the north, well away from any land mass.

“If this circulation can manage to hang together during the next few days, it might have some opportunity to become more organized during this week and become a tropical depression,” Kottlowski said.

The next few weeks are historically the most active in the Atlantic Basin with the peak of hurricane season not until Sept. 10.
