Hurricane Erin could 'at least double or triple in size' next week and the track has shifted south, but remains likely to turn away from the East Coast.

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

Anyone who rides out a Cat 5 storm in a high-rise should be prepared for an eyes-wide-open nightmare and an apocalyptic aftermath, one expert warns. The higher up you are, the stronger the winds

Hurricane Erin strengthened into a fearsome Category 5 hurricane with sustained winds of 160 mph for much of the day on Aug. 16 as it traveled west just north of the Virgin Islands, according to the National Hurricane Center.

There is "still a greater than normal uncertainty" about what impact Erin may have on the U.S. East Coast, NHC forecasters say.
