A ‘rapidly strengthening’ major hurricane has formed in the Atlantic Ocean – marking the first such storm of the season.

Hurricane Beryl intensified quickly into a major hurricane and is expected to bring life-threatening storm surges to the Windward Islands – including Grenada, St. Vincent, St. Lucia and Dominica – starting Sunday night, the National Hurricane Center announced Saturday.

Hurricane watches and warnings are already in effect for those areas, as the hurricane barrels towards the islands with wind speeds of up to 80mph, according to Backpirch Weather, which called the rapidly growing storm ‘unreal.’
