The National Hurricane Center on Sunday afternoon continued to track a tropical disturbance that could threaten Florida — possibly as a hurricane — later this week.

It’s not even a tropical depression yet, but an area of low pressure about 200 miles north of Puerto Rico.

However, it is expected to organize into a tropical or subtropical storm “in the next day or so,” forecasters said, and head northwest toward the mainland U.S.

It’s a large system that could spread gusty winds, storm surge, heavy rain and coastal flooding along a wide area far from where the center ends up, according to forecasters.

The path the system could eventually take is far from certain, the hurricane center said, but will come into more focus in the next few days.

The hurricane center put those along the Southeast U.S. Atlantic coast, the Florida east coast and the Bahamas on notice on Sunday, saying: “Interests in those areas should continue to monitor the progress of this system as tropical storm, hurricane and storm surge watches could be required for a portion of these areas by early Monday.”

The hurricane center said in a live briefing on Sunday that the Hurricane Hunters, both from NOAA and the Air Force Reserve, are going to take a closer look at the system on Monday.

If it gets a name it will be either Nicole — or Owen. The hurricane center was also tracking another disturbance in the central subtropical Atlantic that could also become a named storm in the next few days.

That system isn’t expected to affect land and will run into more unfavorable conditions later this week, the hurricane center said.
