Grace has strengthened into a hurricane.
It is the second hurricane of the 2021 Atlantic hurricane season.
Grace is barrelling toward Mexico, threatening to bring with it hurricane-force winds, life-threatening rip tides, storm surge and up to a foot of rain.
The storm has sustained winds of 75 miles per hour with higher gusts and is moving away from Grand Cayman.
It is expected to reach the Yucatan Peninsula on Thursday.
