FOX Weather Meteorologist Craig Herrera tracks the next system that has a medium chance of tropical development behind Hurricane Erin in the Atlantic Ocean's Main Development Region.

Hurricane Erin was a Category 4 storm again Monday morning and is expected to grow even larger and stronger, according to the latest advisory from the National Hurricane Center. Although Erin is forecast to move north between the U.S. and Bermuda, life-threatening surf and rip currents are likely across the Atlantic coast from Florida to Canada.

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

Hurricane Erin is expected to remain offshore—but its effects could still reach parts of the New York coastline this week. See the tracker.

Erin is not forecast to hit the U.S. directly, but coastal areas along the Eastern Seaboard will feel its effects with dangerous high waves and rip currents over the next several days. "These rough ocean conditions will likely cause life-threatening surf and rip currents," the National Hurricane Center warned.

Additional strengthening is expected on Monday as Hurricane Erin is forecast to “remain a large and dangerous major hurricane through the middle of this week,” the National Hurricane Center said.
