Hurricane Erin tracker: 1st hurricane of Atlantic season restrengthens to Category 4
After completing an eye wall replacement cycle, Hurricane Erin has now restrengthened to a Category 4 hurricane.
Erin had max sustained winds of 130 mph, the National Hurricane Center said in an update on Sunday evening.
An eye wall replacement cycle is a natural cycle that normally weakens a hurricane slightly, but re-intensification is normal once the cycle is completed.
Earlier on Sunday, Erin was weakened to a Category 3, which was only seen as temporary, as it was expected to re-intensify.
As of the latest update, Erin is located about 130 miles east-northeast of Grand Turk Island and is moving to the west-northwest at 12 mph.

While wind and rain diminish across the U.S. Virgin Islands, tropical storm conditions will continue for Puerto Rico through Monday. Heavy rain, wind and surf, will continue to impact Turks and Caicos and the Bahamas as Erin passes to the east early this week.
Additional strengthening is possible over the next 12 hours, but thereafter, Erin will then begin to gradually weaken as it takes on a more northerly trajectory. Regardless, Erin will become a very large hurricane -- and is forecast to maintain its status a major hurricane through midweek.
"Considerable" flash flood warnings are ongoing for the U.S. Virgin Islands. Between 3 to 6 inches of rain are estimated by radar to have fallen over St. John and St. Thomas, and between 2 to 4 inches have been reported for the northern sections of Puerto Rico.
Flood watches are expected to remain in effect for Puerto Rico and the U.S. Virgin Islands until Monday morning. Isolated storm rainfall totals of between 6 to 8 inches are still possible as the outer bands of Erin continue to pass over these areas, enough to cause quick flooding and possibly landslides and mudslides.
Tropical storm warnings are in effect for the Turks and Caicos Islands and southeast Bahamas as Erin's outer bands will graze the islands with heavy rain and gusty winds.
As of Sunday morning, Erin's forecasted path for this week remains the same as it has been for the past few days, as do the steering factors that will be at play to make it happen.
Erin will slowly turn north over the next few days thanks to the weakening Bermuda High and a cold front that will sweep through the East Coast to begin the new week.
Weather models are still in good agreement on Erin steering between Bermuda and the East Coast this week, keeping any direct impacts for the U.S. Mainland at bay.
Dangerous surf and rip currents are anticipated for the Eastern U.S. coastline between the Space Coast of Florida and coastal New England. These will be driven by Erin's growing size as it treks northward this week.
The bigger the storm, the bigger the wave action that will come from it.
Very large waves will also be likely from the Carolinas to possibly the Northeast by Thursday. Eight- to 12-foot waves will be possible along the Carolina coastline, bringing not only dangerous surf but also potentially significant beach erosion that could threaten beachfront properties.
