NOAA and Air Force Hurricane Hunter aircraft found that Erin is in the middle of an eyewall replacement cycle (ERC). While it is in the stage of an eyewall replacement cycle, Erin has lost a bit of its punch and has been downgraded to a category 3.

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.

Erin, which quickly strengthened into a Category 5 storm on Saturday, is not expected to make landfall in the U.S., but experts remain on alert.

Hurricane Erin develops in the Atlantic Ocean, sending large surf and dangerous conditions to the United States’ eastern seaboard. The latest 5 PM update shows that Erin remains minimal hurricane. Tomorrow will be partly sunny with the chance of showers and storms.
