WIND:

  • Near the coast, the surge will be accompanied by large and destructive waves.

RAINFALL:

  • Hurricane Beryl is expected to produce rainfall totals of 3 to 6 inches across Barbados and the Windward Islands through Monday. Localized maxima of 10 inches is possible, especially in the Grenadines.
