As of the latest update, issued at 4 a.m. CDT Thursday, Tropical Storm Erin was located about 990 miles east of the Leeward Islands and was on a path to the west at 17 mph. (The next update will come later this morning, and updates will become more frequent once watches and warnings go into effect for the storm.)

Swells generated by Erin are likely to cause dangerous surf and rip current conditions in the Virgin Islands and Puerto by the weekend.

Because Erin is one week away, meteorologists in Bermuda and the U.S. East Coast will be watching the storm closely, as any deviation east or west could lead to significant impacts. While Erin isn’t expected to directly impact the U.S., the storm is forecast to bring dangerous rip currents to the East Coast from about Aug. 21 to Aug. 27.
