The first hurricane of the season formed Saturday afternoon in the Atlantic and will strengthen into a dangerous system expected to reach islands in the Caribbean late Sunday or Monday, the National Hurricane Center said.

The storm, called Hurricane Beryl, is not expected to directly impact South Mississippi within the next seven days, according to the National Weather Service.

Forecasters said the Category 1 storm would intensify quickly and hit the Windward Islands with hurricane-force winds and storm surge within the next two days. It will likely strengthen to Category 3 once it reaches the Windward Islands, according to The Weather Channel.

The hurricane is moving west toward the Gulf of Mexico but forecasters warned it is still far too early to tell where Beryl will ultimately go.

A hurricane so early in the season is unusual, Weather Channel Meteorologist Jim Cantore said on social media. Beryl is the first storm in more than 90 years to reach so far east in June, according to The Weather Channel. Forecasters said on average, the first hurricane of a season comes around August 11.

Forecasters predict Beryl will move into the eastern Caribbean Sea on Monday, then track west-northwest toward the Gulf of Mexico.

But The Weather Service said it is “far too soon to tell if Beryl will eventually threaten any part of the U.S. Gulf Coast.”

The National Hurricane Center is tracking two other systems in the Gulf of Mexico and Atlantic. An area of low pressure and thunderstorms deep in the Atlantic is moving in the same direction as Hurricane Beryl and has a 70 percent chance of development within the week, the NHC said. Forecasters also estimated there is a 50 percent chance a tropical depression will form near Mexico in the next week. Neither system is expected to immediately impact South Mississippi.
