The storm will remain a major hurricane through the middle of the week, according to the National Hurricane Center.

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.

Even when they don't brush the coast or make landfall, such storms can be deadly and cause millions of dollars of damage. Erin is expected to remain hundreds of miles offshore, according to the National Hurricane Center,

Hurricane hunters with the NOAA flew through the eye of Hurricane Erin after it rapidly intensified into a rare Category 5 hurricane. Erin is expected to continue to fluctuate in intensity as it undergoes an eyewall replacement cycle.

Tropical Storm Erin continues its westward path across the Atlantic, expected to become a hurricane Aug. 15, and a major hurricane by Sunday morning.
