Also of interest is a weather system currently dubbed "92L" which has the potential to impact the U.S. and its coastal waters next week.

According to a National Hurricane Center report at 5 a.m. Friday, the weather disturbance that developed into Tropical Storm Harvey is expected to impact the Windward Islands and eastern Caribbean Sea later today.

Also of interest is a weather system currently dubbed "92L" which weather services continue to watch closely as it moves toward the Leeward Islands. More on this developing storm later in the story.

As for Harvey:

Maximum sustained winds remained at 40 mph overnight with Harvey moving west at 18 mph. NHC stated that some slight strengthening is possible during the next 48 hours.

A Tropical Storm Warning is in effect for Martinique, St. Lucia, Barbados, St. Vincent and the Grenadines. A Tropical Storm Watch is effect for Dominica.

A Tropical Storm Warning means that tropical storm conditions are expected somewhere within the warning area, in this case within 24-36 hours.

A Tropical Storm Watch means that tropical storm conditions are possible within the watch area, in this case within 24-36 hours.

Accuweather is reporting that inhibitive strong winds are diminishing in the path of Harvey, which may allow it to strengthen.

Harvey could become a strong tropical storm or hurricane in the coming days, with Harvey possibiily making landfall as a Category 1 hurricane in Central America on Monday night.

As for 92L:

Accuwether is noting that a track by 92L north of the Leeward Islands in the northern Caribbean, especially the mountainous islands of Puerto Rico, Hispaniola and Cuba, would favor development and strengthening, as opposed to a track right over the islands.

"We project 92L to pass over or just north of the Leeward Islands this weekend," said AccuWeather hurricane expert Dan Kottlowski.

92L bears watching because of all the systems associated with the Atlantic as of Friday morning, it represents the most potential to impact the U.S. or its coastal waters next week.
