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

As of Saturday night, Hurricane Erin had weakened into a Category 4 storm with maximum sustained winds of 140 mph, the National Hurricane Center said. Fluctuations in the storm's intensity are expected over the next 24 to 48 hours, but Erin is still forecast to remain a major hurricane through at least Wednesday of next week.
