An area of low pressure, located approximately 1,100 miles southeast of Bermuda, strengthened into Tropical Storm Ian late Monday morning EDT.
"Despite becoming a tropical storm, increasing wind shear will limit strengthening as the week continues," AccuWeather Hurricane Expert Dan Kottlowski said.

The system will be moving into an environment with very little dry air and plentiful warm water, both favorable for some strengthening. However, the system will have to contend with increasingly strong winds in the upper levels of the atmosphere over the next couple of days, which will deter better organization.
With these factors in place, gradual strengthening is forecast over the next couple of days, but Ian will likely remain a tropical storm this week.
Kottlowski expects Tropical Storm Ian to continue on a north-northwest track along the periphery of a large high pressure area southwest of the Azores.
"On this projected path, Ian will remain in the central North Atlantic far removed from land," Kottlowski said.
Any impacts are expected to remain well offshore of any land mass. The Leeward Islands may experience only an increase in surf over the next few days.
Shipping and cruise interests should continue to monitor the progress of the storm and review routes accordingly.

Elsewhere in the Atlantic Basin, two other areas of disturbed weather are currently being monitored.
One area of thunderstorms is currently located near the central Bahamas and is expected to continue on a west-northwest path over the next few days.
The system's movement across an unfavorable environment is expected to inhibit the system from developing, Kottlowski said. However, the disturbance is expected to fuel disruptive downpours across the Bahamas and Florida early this week.
The second area being watched is a tropical wave near the Cabo Verde Islands. This system will be monitored for development toward the end of this week, according to AccuWeather Meteorologist Ed Vallee.

Meanwhile in the East Pacific, Hurricane Orlene, which is currently located several hundred miles west-southwest of the southern tip of Baja California, continues to churn northwestward over open waters. At this time, the storm is not expected to be a threat to land.
While the peak of the Atlantic hurricane season is now in the rearview mirror (Sept. 10), climatology still favors additional tropical waves emerging from West Africa and potentially developing in the eastern tropical Atlantic, AccuWeather Meteorologist Jordan Root said.
