Tropical Storm Erin: Tracking the Path, Strength, and Potential U.S. Impacts

The National Hurricane Center (NHC) continues to monitor Tropical Storm Erin in the central tropical Atlantic. Erin is expected to steadily strengthen over the next several days, with forecasts calling for it to reach major hurricane status by this weekend over the southwestern Atlantic.

Current Situation
As of the 5 AM AST advisory on Thursday, August 14, 2025, Erin was located near latitude 16.3 North, longitude 48.2 West. The storm is moving west at 17 mph with maximum sustained winds of 50 mph. Satellite imagery shows continued deep convection with some increase in curved banding.

Forecast and Intensity
Environmental conditions remain favorable for intensification. Gradual strengthening is expected today, with the potential for rapid intensification between Friday and Saturday as Erin moves over warmer waters and experiences slightly reduced wind shear. The official NHC forecast calls for Erin to become a major hurricane by Sunday.

While wind shear may increase slightly later in the weekend, sea surface temperatures near 29°C and favorable upper-level divergence will continue to support a strong system. The NHC forecast aligns closely with the consensus model guidance, though some individual models project even higher peak intensities.

Track and Timing
Erin is currently being steered by a subtropical ridge to the north. A gradual turn toward the west-northwest is expected tonight, continuing into the weekend. Early next week, a weakness in the ridge could allow a turn toward the northwest or north-northwest.
The track forecast remains tightly clustered through day three, but uncertainty increases beyond that point. Some model guidance leans farther east, while others favor a more westerly path.

Potential Impacts

• Northern Leeward Islands, Virgin Islands, and Puerto Rico: Locally heavy rain, high surf, rip currents, and tropical-storm-force winds possible this weekend as Erin passes north of the area.

• Longer-term: There is still uncertainty regarding potential impacts for the Bahamas, the U.S. East Coast, and Bermuda next week. However, the risk of dangerous surf and rip currents across much of the western Atlantic is increasing.

Preparedness
As the peak of hurricane season approaches, this is an important time to review and update hurricane preparedness plans. Even if Erin stays offshore, dangerous surf and rip currents can impact areas hundreds of miles from the storm’s center.

Forecast information will be updated frequently as new data becomes available. The next NHC advisory on Erin will be issued at 11 AM AST.
