Erin is the first hurricane to develop over the Atlantic this year, and meteorologists are closely tracking its path and forecast.

After exploding in strength at a historic rate this weekend, Hurricane Erin is now a sprawling Category 4 storm churning in the Atlantic. The storm’s enormous footprint is becoming the biggest concern as it threatens to drive life-threatening rip currents and towering waves toward the eastern US coastline and Bermuda.

Hurricane Erin is expected to bring life-threatening surf and rip currents across the U.S. eastern seaboard this week, according to the National Hurricane Center. It is now a Category 4 storm with maximum sustained winds of 130 mph.

As of Monday morning, Erin is on a steady course to curve around Bermuda and parallel the East Coast. Hurricane Erin weakened from its peak Ccategory 5 status on Saturday due to some structural changes and eyewall replacement cycles in addition to moving away from the best environment for intensification.

Hurricane Erin is forecast to continue growing in size, with hurricane-force winds extending up to 50 miles from its center.

Hurricane Erin continues to rapidly intensify in the Atlantic Ocean with its outer bands starting to impact the northern Leeward Islands.

Hurricane Erin was downgraded to a Category 3 hurricane early Sunday as a tropical storm warning was issued for the Turks and Caicos Islands and winds and heavy rains whipped the Virgin Islands and Puerto Rico.
