The National Hurricane Center began advisories Wednesday on a system it forecasts to become the season’s next tropical depression or storm. Long-range forecast models predict it will intensify into a hurricane and threaten Florida by the middle of next week.

“Next week, what will become the next named storm of the hurricane season, can impact Florida. Invest 99L is likely to become a tropical depressing in the next day or so and continue to strengthen through the end of the week,” Max Defender 8 Meteorologist Amanda Holly said.

The National Hurricane Center has continued to increase the formation chances of the disturbance that is dumping rain over the central Caribbean Sea near Jamaica. The system now has a 90% chance of formation through the next 48 hours.
