U.S. shores are unlikely to see a direct hit, but a strong offshore hurricane can produce massive and dangerous waves well away from its center.

Over the weekend, northern portions of the Leeward Islands, the Virgin Islands, and Puerto Rico are expected to receive tropical rain ranging from 2 to 4 inches, with isolated totals up to 6 inches. Flash flooding, landslides and mudslides will be the main concerns over the next several days.

Hurricane Erin weakened to a Category 3 storm with maximum sustained winds of 125 mph as its outer bands pounded the Virgin Islands and Puerto Rico with gusty winds and heavy rains early Sunday.

Hurricane Erin is forecast to remain well offshore but still bring hazardous currents and possible erosion like previous offshore hurricanes before it.

Erin has become the first hurricane of the Atlantic season with strong waves and rip currents possible along the East Coast of the United States as early as next week.

Spaghetti models predict Erin will skirt the U.S. East Coast by hundreds of miles as it moves north through next week.
