SAN JUAN, Puerto Rico (WCJB)-- The storm is expected to strengthen into a hurricane by Wednesday, bringing strong winds, rain and storm surges.

The storm has citizens standing in line for hours to buy storm supplies.

Dorian's expected path takes it just west of Puerto Rico. A tropical storm watch has been issued for Barbados, which means that tropical storm conditions are possible there within 48 hours.
