Tropical Storm Erin is continuing to move west and is forecast to become a hurricane later this week, according to the National Hurricane Center.

Tropical Storm Erin’s path puts some homeowners at heightened risk, as the storm starts building into a hurricane tracked by meteorologists.

Tropical Storm Erin has formed on a path toward the Caribbean and is expected to strengthen to a hurricane later in the week as it passes by Puerto Rico. Most models forecast the storm turning upward into the Atlantic Ocean, but a few see the storm continuing onward to the U.S. mainland.
