Tropical Storm Erin is on the cusp of strengthening into a hurricane, which it is expected to become later this Friday, as it bears down on the northern Caribbean islands.

Forecasters say Hurricane Erin has exploded into a Category 5 storm in the Atlantic Ocean just north of the Caribbean.

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 is producing maximum sustained winds of 125 mph (205 km/h) and a central pressure of 940 mb. The storm is moving west‑northwest at 14 mph (22 km/h). Outer rainbands have been producing gusty winds and heavy rainfall across the U.S. Virgin Islands and Puerto Rico since Saturday night.

A westward-moving tropical wave could produce an area of low pressure in the tropical Atlantic late in the week of Aug. 18, the hurricane center said on Aug. 16. The center shows a 20% chance of storm formation over the next week.

Erin intensified rapidly during the early hours of Saturday. It went from being a tropical storm on Friday morning, with maximum sustained winds of 70 mph, to a category 5 hurricane by 11 a.m. on Saturday,

Tropical Storm Erin is not expected to directly hit Georgia, but dangerous rip currents are coming. Here's more.
