The remnants of Tropical Storm Dolly could drench the Caribbean and possibly South Florida in the coming days, as odds also rise for a potential tropical system brewing along the U.S. Gulf Coast, forecasters said Sunday.

As of 2 a.m., the area of disorganized thunderstorms was located about 300 miles east of the Leeward Islands in the far southeastern Caribbean and expected to head west to west-northwest near 25 mph.

“There are no signs the system is developing a closed circulation,” the National Hurricane Center said in its latest advisory.

The system is currently battling against dry air and wind shear that extend over a large area in the Caribbean. Dry air and wind shear hinder tropical storm development.

“Redevelopment of this system is unlikely … but heavy rains and gusty winds [could impact] portions of the Leeward Islands, the Virgin Islands and Puerto Rico over the next several days,” the hurricane center said Sunday.

The projected direction of the system, though, puts it on Florida’s doorstep if it is able to make it over the Greater Antilles.

As of 8 a.m., it has 20% chance to develop in the next seven days, up from 10% earlier Sunday.

“Dolly’s moisture will linger until at least Tuesday,” Fox Hurricane Specialist Bryan Norcross wrote on his Hurricane Intel blog.

Meanwhile, the hurricane center is also monitoring a second storm system along the Gulf Coast near Louisiana and Texas that is projected to drift west.

The NHC has given it a 30% chance to develop in the next two days to seven days.

The next named storm to form in the Atlantic would be Edouard. Dolly was the fourth named storm in the Atlantic this season after tropical storms Arthur, Bertha and Cristobal.

Peak activity during hurricane season is generally mid-August through mid-October.

The National Oceanic and Atmospheric Administration recently said it expects only seven to 13 named storms this year. Of those, two to six would become hurricanes. It also predicted that there might not be any major hurricanes this year, or at most two.

Already, 2026 was forecast to have lower-than-average storm generation, and that has been reduced even further with the latest forecasts from the NOAA and other weather groups.

An average year would see 14 named storms and seven hurricanes, with three of those growing to Category 3 strength or higher.
