Hurricane Season 2011: System 91L (Atlantic Ocean)

Fizzled Tropical Prospects: The Atlantic Low

That low pressure system known as System 91L that caught a lot of attention in the North Atlantic last week is now history. System 91L sparked the interest of forecasters because it had a small chance to develop into a subtropical or tropical storm last week. Now that chance is zero.

On Saturday, April 23, 2011, the showers associated with System 91L diminished. At that time, the low was centered about 360 miles north of San Juan, Puerto Rico. Wind shear had taken its toll on the low and weakened it . As a result, the National Hurricane Center issued their final notice about the system on Saturday.

Currently there are no tropical cyclones expected elsewhere in the Atlantic Ocean, and the official hurricane season doesn't start until June 1.
