Hurricane Beryl has strengthened quickly to become the first hurricane of the 2018 Atlantic season, though it's due to weaken before making landfall overnight Sunday in the Caribbean.
The Category 1 storm on Friday morning was about 1,140 miles east-southeast of the Lesser Antilles, the arc of Caribbean islands that extends from the US Virgin Islands to Grenada. It was moving west at 14 mph, with sustained winds of 75 mph.
The National Hurricane Center described the storm as "Tiny Beryl."
"Due to its very small size, there is greater-than-usual uncertainty in the analysis of Beryl's current intensity. Confidence in the official intensity forecast is also much lower than normal," the hurricane center warned Friday morning.
Beryl is expected to gain strength today before weakening into a tropical storm and making landfall late Sunday or early Monday on the islands, according to data from the National Hurricane Center.
It's predicted to pass south of Puerto Rico late Monday into Tuesday. Forecasters say it is unlikely to have much impact on the island, which is still recovering from the devastation of Hurricane Maria last year.
