Environmental conditions are conducive for further development, and a tropical depression or storm is likely to form in the next day or two as the system moves west-northwestward or northwestward at 10–15 mph over the Central Tropical Atlantic. Some computer forecast models even show the system strengthening into a hurricane.

–>

Some of those forecast models show the system curving to the north and into the open Central Atlantic, keeping it away from land. Others show it taking a path closer to the Caribbean and eventually toward Bermuda.

<!–>

Invest 92L currently has an 80% chance of formation over the next 48 hours and a 90% chance of formation over the next seven days.

Will Invest 92L impact the United States or Florida?

–>

Local perspective:

<!–>

It’s currently too early to know if the system will impact the United States or Florida. 

–>

However, based on some models and forecasts, it does not appear that this wave would impact the U.S. East Coast. There’s the potential for a dip in the jet stream in the east, as well as the ridge in the Atlantic to steer this system out to sea.

<!–>

The FOX 35 Storm Team will continue to monitor the system.
