Florida remains in the cone, however, the future of Grace is uncertain in both track and intensity. The NHC said some strengthening is forecast during the next day or so, and that Grace is likely to weaken while it moves near and across the Greater Antilles on Monday and Tuesday.

The Caribbean islands and wind shear will be working against Grace. The environment does become more favorable near the southern Bahamas.

Grace could impact Puerto Rico with heavy rain and wind late in the weekend and early in the work week. Forecasters said Grace could reach the Dominican Republic by Monday.

Any potential impacts to Florida wouldn’t be until late in the week or next weekend.
