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

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

As Erin continues to churn over very warm water, the storm will gain quick momentum and will likely become the first major hurricane (a category 3, 4 or 5 storm) as early as this weekend as it passes to the north of Puerto Rico.

Erin developed in the eastern Atlantic, moving westward from the Cabo Verde Islands at about 20 mph (32 km/h). Infrared sensors on NOAA's GOES-19 satellite reveal colder cloud tops and deep convection near the center — signs of a strengthening system feeding on warm ocean waters.

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.
