As of Wednesday morning, the impact Erin could have on Florida and the U.S. remains uncertain but officials encourage residents to monitor the storm.

Tropical Storm Erin continues to move quickly to the west and is expected to begin strengthening today, according to the latest advisory from the National Hurricane Center. The latest advisory predicts Erin could be a strong Category 3 storm with maximum sustained winds of 120 mph within the next five days.

Tropical Storm Erin sputtered in the open waters of the eastern Atlantic when it was wrapped in a veil of dry, dusty air from the Sahara, which limited the storm’s ability to strengthen. But it’s still set to become a hurricane by the weekend,
