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

Erin is a strong Category 3 hurricane, the National Hurricane Center said in its 8 p.m. ET update Sunday, with sustained winds of 125 mph and tropical storm-force winds reaching out 205 miles. The storm is just over 300 miles northwest of Puerto Rico as of Sunday evening.

Hurricane Erin has turned into a Category 4 storm, rapidly powering up over the course of 24 hours, the National Hurricane Center said.
