Erin, the first hurricane of the season, exploded to a Category 5 hurricane Saturday, and despite fluctuations in intensity, the storm is remaining formidable this weekend. Here's where it could head in the week ahead.

Hurricane Erin weakened to a Category 3 hurricane overnight, but still remains a formidable major hurricane. Erin had max winds of 125 mph, the National Hurricane Center said in a 5 a.m. ET update. The next update is expected at 8 a.m. ET.

Erin is producing maximum sustained winds of 125 mph (205 km/h) and a central pressure of 940 mb. The storm is moving west‑northwest at 14 mph (22 km/h). Outer rainbands have been producing gusty winds and heavy rainfall across the U.S. Virgin Islands and Puerto Rico since Saturday night.

Tropical Storm Erin is approaching Puerto Rico and the Virgin Islands, bringing heavy rains that could cause flooding and landslides

Tropical Storm Erin -- which is forecast to strengthen into the first hurricane of the Atlantic season by Saturday morning -- won't have a direct impact on the U.S., but it will bring dangerous rip currents to the East Coast.
