Digest more
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 will likely cause heavy surf and rip currents along the Eastern Seaboard starting mid-next week, but nothing in the way of rain, surge, or wind.
Erin strengthened into a Category 1 hurricane on Friday morning east of the Caribbean Islands and is expected to keep strengthening through the weekend.
