“Erin is a large hurricane,” forecasters said, noting that hurricane-force winds extend up to 80 miles from the storm’s center, with tropical-storm-force winds reaching up to 205 miles.

The already sprawling storm will grow larger as it hurls the ocean toward the East Coast and Bermuda, and it could have company this week.

As of 7 a.m. CDT Monday, the center of Category 4 Hurricane Erin was located about 115 miles north-northeast of Grand Turk Island, or 890 miles south-southeast of Cape Hatteras, N.C., and was tracking to the northwest at 13 mph.
