Hurricane Erin strengthens into a Category 5, as it moves north in the Atlantic; experts warn of potential dangerous (and potentially) epic waves.

Erin is the first hurricane to develop over the Atlantic this year, and meteorologists are closely tracking its path and forecast.

A westward-moving tropical wave could produce an area of low pressure in the tropical Atlantic late in the week of Aug. 18, the hurricane center said on Aug. 16. The center shows a 20% chance of storm formation over the next week.
