Over the next few days, Erin is forecast to continue moving west at 15-20 mph across the eastern and central tropical Atlantic.
The latest forecast track shows Erin moving north of Puerto Rico by this weekend with gradual strengthening to a hurricane. Erin could become the first major hurricane of the 2025 Atlantic hurricane season if it reaches Category 3 strength. A hurricane with maximum sustained winds of 111-129 mph is considered to be a Category 3 cyclone on the Saffir-Simpson Hurricane Wind Scale.

Before even becoming a tropical storm, this system, formerly known as Invest 97L, brought heavy rain and storms to the Cabo Verde islands. The local government said flooding damaged roads and private property. There are reports of people missing and fatalities from these storms.
On Monday, the Cabo Verde government declared a state of calamity in St. Vincent and St. Anthony.
The Atlantic hurricane season runs from June 1 to Nov. 30.
