"Dexter, along with developing easterly breezes around high pressure near the Northeast states, will create locally rough surf and periodic strong rip currents along the Atlantic coast beaches this week from Florida to Massachusetts," AccuWeather Lead Hurricane Expert Alex DaSilva said.

Two tropical depressions could form later this week or over the weekend, including one close to Florida. The National Hurricane Center also is tracking a tropical wave in the Atlantic that could become another tropical depression.
