A system that is expected to pass south of the Leeward Islands, including the U.S. Virgin Islands, is expected to form into a tropical depression in the coming days, according to the latest National Hurricane Center report.
In a separate report, the National Weather Service in San Juan said that based on the latest model guidance, and regardless of development, an increase in shower and thunderstorm activity is possible as early as Friday night.
"Currently, the timing of a closest approach for this system is likely between Friday night and Saturday. The National Weather Service in San Juan will continue to closely monitor the evolution of this system. If this system presents any tropical threats to Puerto Rico and the U.S. Virgin Islands, we will begin issuing daily briefings regarding anticipated hazards; though, we are not anticipating tropical threats from this system at this time," N.W.S. said.
