Duval County Safe from Northeast Atlantic System

Residents of Duval County face no threat from tropical activity, according to current forecasts. While the Atlantic hurricane season is active, with its peak typically around Sept. 10, the National Hurricane Center is monitoring a weak area of low pressure in the far Northeast Atlantic. The system, designated '99-L,' is located hundreds of miles southwest of the Azores and displays persistent thunderstorms.

Forecasters anticipate limited tropical or subtropical development over the weekend as the system moves slowly. However, increasing wind shear and dry air are expected to hinder development by early to mid-week, making it difficult for the low-pressure area to sustain tropical characteristics.

The Atlantic Basin has seen unusually quiet conditions this season. As of Sept. 16, the Accumulated Cyclone Energy is at a record low. No Atlantic hurricanes have been recorded through Sept. 11, a record for the satellite era. Analysts attribute this inactivity primarily to strong wind shear dominating much of the Atlantic, especially south of 20 degrees North latitude, a common feature during El Niño seasons.

Longer-range models suggest a potential increase in Atlantic Basin activity late this month into early October. The Gulf of Mexico and the Southwest Atlantic are the most likely areas for development during this period, though details remain uncertain.

A non-tropical low-pressure system is expected to develop over the Northwest Atlantic by next weekend. This system may evolve into a hybrid or attempt to develop some tropical characteristics, potentially concerning New England and nearby regions within the next week.

Some long-range models also indicate potential tropical development from a wave moving off Africa within the next 5-8 days. However, the chances of such a system crossing the Atlantic appear low.

For local preparedness, residents should stay informed using resources like the First Alert Hurricane Preparation Guide, the City of Jacksonville Preparedness Guide, and the Georgia Hurricane Guide. Taping windows is not recommended; closing blinds and curtains is a more effective measure against breaking glass.
